Chevrolet News:2016 Chevrolet SS Gets A Nip and Tuck

Recommended Posts


Earlier this week, we introduced you the refreshed 2016 Holden Commodore lineup. Now one question that came up was if the Chevrolet SS - a rebadged version of the Commodore - would see any changes. Chevrolet has provided the answer with an announcement of an updated 2016 SS sedan.

 

Changes for the 2016 SS are mostly cosmetic with new vertical ducts to improve aerodynamics and a set of LED lighting. Finishing off the exterior are a set of functional hood vents and nineteen-inch alloy wheels. The 6.2L V8 remains unchanged with 415 horsepower and 415 pound-feet of torque. A new dual-mode exhaust comes as standard.

 

"The 2016 SS design changes more fully express the true driving character of the sedan while further enhancing the car's overall performance," said Todd Christensen, Chevrolet Performance Car marketing manager.

2016 Chevrolet SS Designed for Performance

 

DETROIT – Building on the performance-oriented updates made to the Chevrolet SS last year, the 2016 model features several exterior enhancements that reinforce its presence on the road.
A revised front fascia features new, vertical ducts at the outer edges to direct airflow over the front wheel openings to improve aerodynamic efficiency. The fascia also incorporates new LED signature lighting, while new, functional hood vents and new-design 19-inch cast-aluminum wheels contribute to a stronger appearance for the rear-drive sports sedan.

 

“The 2016 SS design changes more fully express the true driving character of the sedan while further enhancing the car’s overall performance,” said Todd Christensen, Chevrolet Performance Car marketing manager.
What hasn’t changed is the SS’s unique blend of performance, comfort and spaciousness. It features a 6.2L V-8 engine under the hood and turns out an SAE-certified 415 horsepower (310 kW) and 415 lb-ft of torque (563 Nm), and offers a six-speed manual transmission or a paddle-shift six-speed automatic transmission.
A new, dual-mode exhaust system for 2016 complements the V-8 engine with quieter performance at low engine speeds and a more muscular engine note at wide-open throttle.

Looks nice...with the nip and tuck...actually...looks a lot better...although subtle are the touches...makes a difference...

 

However...there is still something about it that I cant put my finger on that I am not too excited about...and it has ALL the ingredients that I WANT from my muscle car daily driver...including the LS3...415HP/415 ft.lbs torque is plenty of ooomph that I require in a daily driver...no need for more...

 

But somehow...I aint interested...maybe its because Im am soooooo excited by the Alpha Camaro...yet the Camaro...is a small 2 door sport coupe...not really my style...its a small pony car...mid-sized muscle is how I roll...

 

I dont know...Im confused... :dizzy:

 

I SHOULD BE LOVING THIS CAR :unsure: ....but Im not.  :(

Is some of it the styling of the SS? I'll admit that I wasn't a fan of the styling. I think some small changes could make a big difference.

It could be...it does not help that the styling of the Chevy SS is a tad on the conservative side. But then again...I wasnt  all that smitten with the Pontiac G8 either...even in GXP trim...although the silhouette is sexy...

 

It does not help either that the exterior colours GM offers on the Chevy SS are also on the conservative side...although that blue colour on the intro to the article is stunning...makes the car look more like a fun car to drive.

 

I absolutely love the interior of the Chevy SS...miles apart from the Pontiac G8...and quite classy...for a Chevy...that interior is befitting for an Oldsmobile...

 

I dont know...

It is what it is and never was intended to sell in numbers great enough to make it profitable with whole sales changes.

It is a car where the circumstances and the time it is built and where it was built have conspired to hold it back and bring its end.

I am hoping the new GM culture has plan to move a similar model here built on the Alpha and merge it with the Impala. I am not holding my breath but you always dream.

The best thing in the world was this was a Holden or we would never have had it. The worst thing is it was a Holden coming from half way around the world from a market that sells less cars combined than the Camaro alone.

When GM finally green lit the Chevy version to be sold to the public, GM itself handicapped the vehicle and limited its sales by only offering a V8. The Caprice is only for government fleets, etc...

 

The Pontiac G8 never took off because of circumstance. Recession and bankruptcy and consequent killing off of Pontiac.

 

Had GM offered multiple engine offerings, like the G8, and more so like the Zeta Camaro, (the Camaro's LFX 3.6 or even the slightly less powerful version in the Holden Commodore) then the SS would have sold more...

 

I understand the whole economics part of the equation...built in Australia and shipped to America...not even in Canada...therefore too many options for the Chevy SS might have been a money losing proposition...so I get that...

 

What I dont understand is why GM didnt commit to building the Chevy SS in Canada along side the Camaro?

What I dont understand is why GM was afraid to commit?

.

Its understood that the G8 failed because of bad timing....or was it other reasons that GM knows and wont tell us?

 

But yeah...we  were lucky to have experienced these cars.

 

I remember back in the day when we had the Cadillac Catera here in North America with that dog of an engine and I was reading about Middle Eastern Lumina SS cars, i was thinking to myself...WTF? I thought North America was home to the Muscle Car...what gives?

 

And finally when Bob Lutz gave us...well Americans...the Monaro as the Pontiac GTO....I was super elated...because THIS is  FINALLY a step FORWARD in getting back our muscle cars...the F-Body pony cars died...and the closest to a muscle car we had was those German cars from BMW with the "M" badge and AMG trimmed Mercedes Benzes...

 

And then...the G8...WOW!!!

 

And the Zeta platform....so I heard because I havent driven a Zeta car....Camaro/G8/SS or otherwise...is a solid performing platform. GM and Holden REALLY dialed it in... Its a shame that the SS and the Holden versions are going away. I feel the same way I felt when the F-Body was killed off.

 

Yes I know...I said that I did not care for the SS or the G8 all that much...it still doesnt change the fact that I KNOW the SS and the G8 and obviously the Holden models were fantastically engineered muscle cars...and as of now...NOTHING is said to replace them...and THAT is extremely sad...

It is an improvement, albeit a small one. It's still not aggressive enough to draw many buyers' looks.

 

I for one have no problem with the looks, as they're fitting on a car like this. My problem lies with how GM packaged the car. They should have either built lower-end models so they could be competitive with Charger, or if they wanted to stick to an expensive one-car-fits-all approach, they should have found a way to get the new LT1 and trannys in there.

 

As it stands, it's a fantastic car to drive, especially in 6MT form. It's a new BMW E39 M5. But with modern features and better reliability. I've given serious thought to buying one, but my employee price is still in the 42K ball park, and I just can't justify it. I'll wait for a GM corporate demo to pop up with a few thousand miles that I can get for cheap, and maybe make a move then.

let's enjoy the car for what it is and that it is still available.  I would love a white SS manual + MT.

 

It could never be a daily driver for me in winter here or in daily traffic but as a good fun car or trip car it would be the bomb.  I'd make better use of this than a current Camaro.  A 16 Camaro 2.0 turbo MT would be a nice garage companion to this  ;)

The limitations of this car are many,. Some self imposed by GM for various reasons an some due to circumstances. Some of these we know why well and some we will never know. It is what it is.

 

I am just hopping there is an Act 2 that we are not aware of yet. I would love to see a melding of the Impala and Camaro into a full line larger sedan. This would remove it from the Malibu that is growing in size. It would offer a lighter RWD car than what Chrysler has and what Ford does not offer. It would still provide a police version. Finally It would give a chance to offer it in a 275 HP 4 to a 455 HP V8 or more. 

Being on an Alpha would help control the cost of a lower volume model. Lets face it this size car will never sell in the numbers the original Caprice of the 80's did as the market has down sized. Make it with a different body but make it more Camaro under the skin. The suspension should carry pretty much right over accept for spring rates.

 

I hope the silence on the Impala and SS hold more than they might.

 

I know it is something Mark would approve of but can he make the business case to get it approved?

This is where Im conflicted...

 

The Impala name...

Gone are the days when a RWD Impala meant muscle...and its been a very long time...

The 1994-1996 Impala SS does not count...most people recognize the Impala name as a family hauler be it as a RWD boxy car of the 1980s or FWD cars that replaced a Lumina....most people dont even remember the Lumina...but they equate the Lumina to an Impala...

 

Going back to the 1980s...even the Impala name is confused with Caprice as many people equate that body style to solely a Caprice and as cop cars...and THAT is why the 1994-1996 Impala SS does not count...as many people equate THAT body style as a cop car as well...

 

What Im trying to say is that...I dont think a RWD Impala SS in 2016 or beyond will have any effect to entice people to buy these cars or even show up at a Chevy dealership to look at them and them drive off in a brand new Malibu, Cruze or Equinox...

 

It seems like the Super Epsilon Impala is a mild hit...but like you said...the numbers are not that high as people have downsized in cars...but do buy SUVs for family haulin' needs...

 

The Super Epsilon Impala has rendered the Buick Lacrosse obsolete...

So...that leaves another problem....the Cadillac XTS is going away...GM does need to fiil in that hole...Buick SHOULD get the next XTS...make that into the next Park Avenue? B

ut is there enough room to continue to offer two plebian Super Epsilon cars?

 

Either the Impala should continue on or the Lacrosse...but not both...

 

However...should the Lacrosse continue on...I dont think a RWD Impala based on Camaro hardware and software which is based on Cadillac ATS hardware will not make a big splash either...and we saw it in the Chevy SS...

 

Many say its not the name of a car that projects sales of a model....Ill  agree to that to a certain degree...Had they called the Chevy SS an Impala SS...I dont think that would have generated much sales either...

 

And its not because the Chevy SS had the LS3 under the hood either...415 HP and 415 ft.lbs of torque is still a healthy amount of power to market to people...

 

What I am trying to say is that...the Chevy SS failed in the market place in the US...its because the average Joe does not want a muscle car anymore to haul around his family...the Chrysler/Dodge cars sell the way they do...because of V6 under the hood...not V8...

 

So...If a RWD Chevy Impala is in the cards...if the sole engine offered is a V8 so the car would be called Impala SS...it will generate just as many sales as the hevy SS generated...

 

And THAT is why Im conflicted...because I have come to realize...that muscle cars...for the average Joe is a thing of the past...

 

 

Does my speech make ANY sense?

I seem to go around in circles...but yet...it makes sense to me...does it makes sense to you?

Or am I completely in left field somewhere collecting daisies while the baseball game is unfolding before my eyes and the fly balls are passing over my head?

I think you are over thinking this.

As it is now the Impala is for the most part not nor is it expected to be a Volume model. It under cuts the lacrosse fine and makes added income off the platform. This for sure is a low risk no brainer.

 

Now my thought here is one the Impala name is not damaged. Second many people still equate the performance models of the 60's with the name.

 

What I would like it to see this car morph into what would be a 4 door Camaro with out being a Camaro. We would have styling of it's own and make even more  use of the Camaro parts they have made up. The price would be such that it would entice people to pay more for a RWD car and the profit per unit would go up. This would make more money on a lower volume car. Lets face it the Impala as it is now can move up more because one people would not pay it for a FWD car and we already have a Lacrosse.

 

Then for Buick you keep on offering AWD and add the AWD and RWD Omega.

 

The name Impala would not change a thing about the present car. What many fail to understand or realize is the SS was a program from way back around Chapter 11 time. For what all the reasons it got here late in the game and was pushed through. I had a talk with the head of the GM RWD Performance platforms Oppenhiser years ago and he told me then the car was coming but there was no set time for reasons he could not give.

 

Like the present Malibu the SS was a vehicle caught at a time in GM history where things did not get all they could because of the amount of time and money going into other projects. Some of these models were just to keep the line up fresh as they finished the Alpha and other things that would carry them forward. If GM had not used these still born models they would be like Chrysler struggling on with older models for 5 years or more. GM Dumped money into these models in 08 to try to get them to a point they could be taken off the shelf when they could to at least offer something new. Even the ZL1 was one of these projects.

 

I just feel there is enough to build a business case for an Alpha RWD sedan at Chevy in lower volumes. It also could serve as police fleets to help round out profits.

 

This would also help put a different twist on Buick and Chevy too.

This model could also serve in most LHD markets the Holden is in too and be exported out to the Middle east etc.

 

While the Impala had some lean years it was never seen as a failure and the equity of the name would be fitting. They could even use it in conjunction with the Caprice name too.

 

Lord knows the Impala SS of the 90's is still a very popular car as the prices continue to climb.

Yeah...I could see the advantages as the way you put them in place.

 

- a platform that would be paid off even faster with government fleet sales. Helping to fund more bespoke Cadillac architecture...

 

- engines and transmissions even suspensions shared with a coupe (Camaro) that would also help amortize said hardware. (irony in this case as it seems that a coupe would take the lion's share of sales in this case)

 

- and of course the world wide appeal of an affordable Alpha based Chevy/Holden. I dont know about the Aussies because their market seems to mirror ours circa 1980/1990 as of today...but then again...Cadillac wants to go world wide...and even in the Middle East...especially in the Middle East...Im guessing Chevy Lumina SS cars that evolved into Caprice SS and Commodore SS...a Cadillac ATS or Cadillac CTS would be a bigger hit than a Chevy equivalent...because of badge snob appeal...and even if Chevy somehow has more brand appeal than Cadillac, even in that region...I would think that Cadillac would want that peace of pie...just to introduce brand appeal to that market...you know...CT8 sales success might rely on that region...

 

 

And by all means...I didnt want to sound like the Impala name is messed up...I wanted simply to say that the name has been thinned out. But I guess you are right...even Millennial youngsters do know about full sized muscle Impala SS'es of the 1960s.

i read recently that the Avenir / clone may become the Commodore replacement and serve as a possible SS replacement.  As if to suggest we may get the Avenir, and then some form of it as an SS for Chevy.  Just to get the Avenir would be nice though.

 

What i wonder, is Buick really developing a new Regal, LaCrosse AND Avenir for the US?

 

AND THEY DON'T HAVE A MID SIZE CROSSOVER

 

Ignore the hot segments and make a bunch of sedans

I too have speculated the Avenir would be coming. I really think the only delay is the CT6 reaching the market and the new Lacrosse coming next year. I would peg 2018 as the year and guess what that is the year the SS and Holden both die. About then the Impala also is need of update or replacement as it will only have till 2019 if it is kept on line at Oshawa. We know the XTS that is on the same line I believe is good till 2019.

 

Either way moves will have to be made and these models fit together with a time line that is plausible.

 

Yes Buick will get a new Lacrosse next year. The Regal should be in just after it.

as for the mid size CUV there is one in China just ready to be built here. The whole thing about importing them is just a UAW negotiation tactic.  I am wondering with word the Terrain may be moving to Spring Hill with the SRX if it may on the longer version and the Buick will be on the shorter Nox Version. That way they do not step on each other at the dealers.

 

Also we have one more  mid size SUV coming too. We have yet to hear much on it but there is one more in the mix.

Build the car right and the name Impala will help with the older buyers and introduce the newer buyers. They may be young but with so many sales over the years with Impala and Caprice the equity is hard not to use.

It is great to see so much enthusiasm over this car with what could have been and what might be.

 

I think the Catera, GTO, G8, and now SS are examples of how Big GM (old and new) could never really "globalize" their models properly.

 

With Holden, you had three fundamental hurdles; 1) Distance to actually ship the product, 2) Different government regulations to build the product, and 3) consumer demand to buy the product.

 

There is an old video that can be found on this site where Bob Lutz gave three reasons for why the GTO didn't quite gain traction when it first was introduced; 1) The design of the car was late in the lifecycle period and did not come to the states with a fresh look.  2)  They shipped the car to places all over the US where the GTO had traditionally high sales (based upon 40 year old data) only to come to find that it was a big hit in SoCal.  That meant shipping a bunch of cars BACK to Long Beach where they first showed up just to be sold.  3)  The car was at a price point a bit too high along with dealer mark-ups.

 

If there is an SS with a MANUAL transmission available in my area, then I would seriously consider buying AND driving it. 

 

If purchased, this would give GM the data it needs to justify a next generation IMPALA SS sedan with the new LT-1 and a SEVEN speed manual.

You are all missing the boat when it comes to law enforcement.  Police officers no longer want SEDANS, they want CUVs built to handle the requirements of the job.  GM needs a Ford Explorer competitor if they plan to sell to law enforcement in volume.  At a local car show I attended yesterday, the town police had the roads closed for the show.  On the ends there were Ford Crown Vic's, around 2009-vintage.  In the middle were new 2014 Ford Explorers and Chevy Caprices (2012-2013 vintage).  Only one cop, a supervisor with a 29k mile 2009 Crown Vic, wished Ford never stopped with the Crown Vic.  The officer I spoke to with the Caprice said it goes like a bat out of hell, but is too cramped in the front seat with the PD computer and other PD equipment; he said he prefers the Explorer.  The other two cops, each with an Explorer, told me they'd never look back at a Crown Vic, Caprice, or Charger again.  Fleet sales of the Explorer to law enforcement are through the roof.  Police Dept's no longer desire nor want sedans.

 

I am a huge fan of the Chevy SS Sedan and the Caprice PPV, were I wish a civilian version was offered.  I would have jumped on either if I could afford the SS or a Caprice was offered to the public (in place of my GMC).  Last November and again in January, I looked at leftover 2014 SS sedans but just couldn't handle the payments - very few sales incentives were available even then.  Many Chevy dealers around me in southern NJ just don't want to stock these cars, and if they do it's usually one or two at the most.  I've recently been looking at dealer stock again and most of the dealers that had two just a month ago are down to one; a lot of other dealers that had one still have it (showroom or concrete pad queen, if you know what I mean).  Even at car shows I see tons of new privately owned Corvettes and Camaros, but only one local show had a dealer display consisting of a Camaro, Corvette, and an SS.  Heck, I just seen a silver SS on the road yesterday - the first spotting in months (and I drive all over south & central NJ and eastern PA).  These SS sedans aren't marketed because: (1) the dealer cost & MSRP is high, (2) incentives do not exist on the SS compared to the rest of the Chevy lineup, and (3) most people that want a powerful car like this are buying BMW M's and Mercedes AMG's while the Average Joe is looking for deals on Chargers, Challengers, Mustangs, and Camaros - none of which can compete with the SS on incentives and price.  I want nothing more than the SS to live on, heck I still drool over each one I see and say if I hit the lottery its the first purchase I'm making.  But the reality is GM was contractually obligated to sell Holden's in the US and this was the only way GM would do it (selling low volume, fully optioned, V8 powered models).

 

GM needs to concentrate on making CUVs that people want (arguably they do with the Terrain/Equinox/SRX), add in heavy duty versions that can serve law enforcement outside of full-size SUVs that LE doesn't want, and realize the market for full-size sedans has shrunk to the point they are becoming a niche market.  GM has the small-to-midsize sedan market well covered, and it should only continue to improve when the new Malibu and Regal go on sale.  Full-size sedans are not what the majority of the buying public want anymore, they want CUVs and so do law enforcement.

      Chevrolet has spilled a bit more information on the upcoming 2019 Silverado's powertrain lineup. The big story is a new turbocharged 2.7L four-cylinder becoming the base engine for the volume LT and new RST trims. We'll give you a moment to work through the shock that you're most likely experiencing.
      The 2.7 is rated at 310 horsepower and 348 pound-feet of torque. The torque figure is impressive when you consider that the 4.3L V6 (now relegated to the W/T, Custom, and Custom Trail Boss trims) produces 22 percent less torque. 0-60 mph is said to take under seven seconds. This engine can also run on just two cylinders. No word on fuel economy, but we wouldn't be surprised if this engine is close to the top in terms of the Silverado's powertrain lineup.
      The complete list of powertrain options available on the 2019 Chevrolet Silverado
      4.3L V6, 6-Speed Automatic: 285 horsepower and 305 pound-feet of torque Turbocharged 2.7L 4-Cylinder, 8-Speed Automatic: 310 horsepower and 348 pound-feet of torque 5.3L V8, 6- or 8-Speed Automatic: 355 horsepower and 383 pound-feet of torque 3.0L Turbodiesel I-6, 10-Speed Automatic: TBD 6.2L V8, 10-Speed Automatic: 420 horsepower and 460 pound-feet of torque “A major focus of the next-generation Silverado is expanding the range of choices. With all-new engines and a broader model range, there’s a Silverado for everyone, whether you’re buying your first pickup or your tenth,” said Tim Asoklis, chief engineer for the Silverado 1500.
      Source: Chevrolet
      A SILVERADO — AND AN ENGINE — FOR EVERY NEED
      The all-new 2019 Silverado 1500 offers six engine and transmission combinations, including an all-new 2.7L Turbo, and V-8 engines with industry-first Dynamic Fuel Management offering 17 different modes of cylinder deactivation DETROIT — With eight trims paired with six engine/transmission combinations, even more customers will find a 2019 Silverado 1500 perfectly tailored to their needs for performance, efficiency, technology and value.
      “A major focus of the next-generation Silverado is expanding the range of choices,” said Tim Asoklis, chief engineer for the Silverado 1500. “With all-new engines and a broader model range, there’s a Silverado for everyone, whether you’re buying your first pickup or your tenth.”
      The all-new 2019 Silverado 1500 propulsion lineup includes:  
      Over half of the models will be equipped with the most advanced V-8s in the brand’s history: updated versions of Chevrolet’s proven 5.3L and 6.2L engines equipped with industry-first Dynamic Fuel Management featuring 17 different modes of cylinder deactivation. An all-new, advanced 2.7L Turbo engine that replaces the 4.3L V-6 as the standard engine on the high-volume Silverado LT and new Silverado RST, expected to offer 22 percent more torque, greater fuel efficiency and a stronger power-to-weight ratio than the current model. Proven 4.3L V-6 and 5.3L V-8 engines deliver full-size truck capability and performance for the most affordable trucks in the Silverado lineup. An all-new, Duramax 3.0L inline-six turbo diesel will be available in early 2019. A Silverado — and an engine — for every need
      Each engine/transmission combination is matched with exterior design and interior features to create distinct personalities for each Silverado trim, based on three broad customer profiles: High Value, High Volume and High Feature.
      High Value — For customers seeking full-size truck capability and the highest level of affordability, the Work Truck (WT), Custom and Custom Trail Boss trims offer two proven engine and transmission combinations:
      Standard: 4.3L V-6 with Active Fuel Management and a six-speed automatic transmission (SAE-certified at 285 hp/305 lb-ft). Available: 5.3L V-8 with Active Fuel Management and a six-speed automatic transmission (SAE-certified at 355 hp/383 lb-ft). High Volume — For customers shopping in the heart of the truck market, the LT, RST and LT Trail Boss trims balance technology, efficiency and performance:
      Standard for LT and RST: All-new 2.7L Turbo with Active Fuel Management and stop/start technology paired with an eight-speed automatic transmission (SAE-certified at 310 hp/348 lb-ft). Standard on LT Trail Boss and available on LT and RST: An updated 5.3L V-8 with Dynamic Fuel Management and stop/start technology with an eight-speed automatic transmission (SAE certified at 355 hp/383 lb-ft). Available on LT and RST: The all-new Duramax 3.0L Turbo-Diesel with stop/start technology paired with a 10-speed automatic transmission will be available in early 2019. High Feature — For customers shopping for a premium truck, the LTZ and High Country trims offer the highest levels of performance and technology, including:
      Standard: Updated 5.3L V-8 with Dynamic Fuel Management and stop/start technology paired with an eight-speed automatic transmission (SAE certified at 355 hp/383 lb-ft). Available: Updated 6.2L V-8 with Dynamic Fuel Management and stop/start technology paired with a 10-speed automatic transmission (SAE certified at 420 hp/460 lb-ft). Available: The all-new Duramax 3.0L inline-six Turbo-Diesel with stop/start technology paired with a 10-speed automatic transmission will be available in early 2019. Improved Driving Experience
      The performance of each engine/transmission combination benefits from a truck that is lighter and more aerodynamic than the previous model.
      “With less weight and less wind resistance, we improved the driving dynamics without sacrificing fuel efficiency,” said Asoklis. “The next-gen Silverado is a bigger truck, but the chassis feels more responsive and acceleration is more pronounced. I would argue it’s the best-driving truck we have ever built.”
      The 2019 Silverado is larger than before, including a wheelbase that is up to 3.9 inches (100mm) longer, yet overall length is only 1.6 inches (41mm) longer, enabling both more cargo volume and more interior room for all cab lengths. Remarkably, it’s also lighter, weighing up to 450 pounds (204 kg) less than the current Silverado when comparing crew cab V-8 models, due to extensive use of mixed materials and advanced manufacturing.
      To improve the aerodynamic efficiency of the next-gen Silverado, the front grille features functional air curtains, similar to those introduced on the sixth-generation Camaro, that reduce wind drag by routing air around the front wheel wells. The powerful side profile also enhances aerodynamics, with an integrated spoiler at the rear edge of the cab that directs air onto the contoured tailgate, reducing wind drag from the bed. Most models also feature active aero shutters integrated in the front grille that close to reduce wind drag and open to provide improved engine cooling when needed. Changes like these result in a 7 percent increase in total aerodynamic efficiency.
      From the family of the Most Dependable, Longest Lasting full-size pickups on the road*
      For the new Silverado, Chevy set the lofty goal of improving on the legacy of the Most Dependable, Longest Lasting full-size pickups on the road. To do so, the next-gen truck will be subjected to more than 475,000 validation tests and accumulate a staggering seven million miles of real-world testing before the first 2019 Silverado 1500 is delivered to customers.
      That includes a battery of tests for the Silverado engines and transmissions that will simulate a range of customer needs:
      Each type of engine was first subjected to a “torture test” in a dynamometer test cell, running for months nonstop to simulate a lifetime of maximum hot and cold cycles. Each Silverado variant is certified to the SAE J2807 standard for towing and payload capacity. Certification requires a full battery of grueling tests such as the Davis Dam test, in which the truck must carry its maximum gross combined vehicle weight up a 7 percent grade in 110-degrees F (43 degrees C) heat, with no reduction in performance, including air-conditioning. Chevrolet engineers prove every Silverado engine and transmission design for lubrication capability on tilt stands, originally developed for Corvette, that tilt at an angle of up to 53 degrees and can simulate angles at a rate of up to 40 degrees a second — the equivalent of up to 1.4g. Production plans
      Silverado production commences with crew-cab V-8 models starting in the third quarter. In the fourth quarter, production will expand to include regular- and double-cab models, as well as V-6 and 2.7L Turbo engines. The new Duramax 3.0L inline-six turbo diesel will be available in early 2019.
      EPA fuel economy estimates and towing/payload capacities are not yet available, and will be announced closer to launch.

      ALL-NEW 2.7L TURBO ENHANCES VERSATILITY OF THE 2019 SILVERADO
      Technological powerhouse delivers performance and efficiency DETROIT — The all-new 2019 Chevrolet Silverado 1500 will be offered with an all-new, technologically advanced 2.7L Turbo that expands the range of available engines and builds upon additional choices to help customers find the Silverado that perfectly suits their needs.
      Standard on LT and RST trims, the new engine delivers an SAE-certified 310 horsepower and 348 lb-ft of torque, for 22 percent more torque than the 4.3L V-6 it replaces. Developed specifically for truck applications, the new 2.7L Turbo inline four-cylinder engine delivers peak torque from 1,500 to 4,000 rpm.
      The next-gen Silverado with the 2.7L Turbo delivers 0-60 mph performance in less than seven seconds and weighs 380 pounds less than the current Silverado with the 4.3L V-6. Compared with competitive full-size trucks, the Silverado 2.7L Turbo is expected to deliver comparable payload capability with greater torque than the 3.3L V-6 in the Ford F-150 XLT and the 3.6L V-6 in the Ram 1500 Big Horn.
      “The new 2.7L Turbo is a technological marvel, with our most advanced valvetrain,” said Tom Sutter, chief engineer for the 2.7L Turbo. “With a broad, flat torque curve and quick throttle response, it punches above its weight, delivering surprising performance and efficiency.”
      The cornerstone of the 2.7L Turbo is an innovative double overhead cam valvetrain that enables:
      Chevrolet’s first use of Active Fuel Management (cylinder deactivation) on a four-cylinder engine. High- and low-lift valve profiles. Continuously variable valve timing. Additional engine technologies supporting the engine’s performance and efficiency include:
      Dual-volute turbocharger housing for improved throttle response and low-speed torque. Chevrolet’s first application of Active Thermal Management, which uses targeted engine heating and cooling to improve engine performance in hot and cold ambient temperatures. An integrated exhaust manifold that is part of the cylinder head assembly and recovers exhaust heat for faster engine and transmission warmup, with quicker turbo response. Stop/start technology that automatically stops the engine in stop-and-go traffic for fuel efficiency. An electric water pump that eliminates the drag of a conventional, engine-driven pump to enhance efficiency. It also enables continual cabin heating even when the engine is disabled by the stop/start feature. Designed as a truck engine
      The new 2.7L Turbo engine represents a clean-sheet design for Chevrolet and was developed from the outset as a truck engine.
      To help generate the strong low-end torque customers expect in a truck, it was designed with a long piston stroke of 4.01 inches (102mm), which is the distance the piston travels up and down within the cylinder.
      The long stroke enables improved combustion and thus a higher compression ratio. Typically, a long stroke can increase the load of the pistons against the cylinder walls, generating more friction. That’s alleviated in the 2.7L Turbo with an offset crankshaft. It is slightly off-center of the cylinders, allowing a more upright position for the connecting rods during their movement.
      To support the high cylinder pressures that come with turbocharging, the crankshaft and connecting rods are made of forged steel and the pistons are made of a tough aluminum alloy with a cast iron ring groove insert.
      All elements of the 2.7L Turbo were designed for the demands of turbocharged performance in a truck environment, and the engine was subjected to the same rigorous durability standards as the Silverado’s proven V-8 engines.
      The 2.7L Turbo features an aluminum block and cylinder head for reduced mass.
      Unique valvetrain offers more precise control
      The 2.7L Turbo’s valvetrain is GM’s first to incorporate variable lift, duration and Active Fuel Management to optimize performance and efficiency across the rpm band. It is a key reason the engine’s peak torque is available at only 1,500 rpm.
      The system’s electro-mechanical variable camshaft effectively allows the engine to operate with three different camshaft profiles, complementing the variable valve timing system to deliver optimized operating modes for different engine speeds and loads:  
      High valve lift for full power. Low valve lift for balance of power and efficiency. Active Fuel Management shuts down two of the cylinders in light load conditions to further conserve fuel. “It’s like having different engines for low- and high-rpm performance,” said Sutter. “The camshaft profile and valve timing is completely different at low and high speeds, for excellent performance across the board.”
      The camshaft design alters the lift of the intake and exhaust valves. As the engine load changes, electromagnetic actuators allow a movable shaft containing different cam lobes to shift imperceptibly between high-lift and low-lift profiles.
      Lift is the distance the valve travels from its seat when opened, and duration is the amount of time the valve remains open. Higher lift and longer duration allow more air to flow into the combustion chamber, so the system’s high-lift lobe profile enhances performance at higher rpm, while the low-lift profile optimizes efficiency at low- and mid-range speeds.
      Dual-volute turbocharger builds torque
      The 2.7L Turbo engine employs an advanced dual-volute turbocharger that elevates the performance and efficiency advantages of a conventional turbo, with quicker response and enhanced low-rpm torque production.
      Rather than a single spiral chamber (volute) feeding exhaust gas from the exhaust manifold to drive the turbine on the turbocharger, the dual volute design has a pair of separate chambers with two exhaust gas inlets and two nozzles to drive the turbine. The design allows the exhaust pulses of the engine to be leveraged for faster spool-up and subsequent boost production, particularly at low rpm, where the effect significantly enhances torque output and drivability.
      It works in unison with the engine’s integrated exhaust manifold/turbocharger housing, which splits the exhaust channels from the cylinder head so the exhaust flows through two separate channels in the turbo housing, based on the engine’s exhaust pulses. When complemented by the precision of the engine’s valvetrain, that separation leverages exhaust scavenging techniques to optimize gas flow, which decreases exhaust gas temperatures, improves turbine efficiency and reduces turbo lag.
      An electronically controlled wastegate and charge-air cooling system support the turbocharger and enhance its effectiveness. Compared to a conventional wastegate, the electronically controlled version offers more precise management of the engine’s boost pressure for smoother, more consistent performance.
      With the charge-air cooler, the pressurized, heated air generated by the turbocharger is pumped through a heat exchanger before it enters the engine. That lowers the air charge temperature by about 130 degrees F (74 C), packing the combustion chambers with cooler, denser air that enhances power production. The system achieves more than 80 percent cooling efficiency with less than 2 psi (12 kPa) flow restriction at peak power, contributing to the engine’s available torque production at low rpm.
      Additional features
      A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump.
      Active Thermal Management helps the engine warm up faster and achieve its optimal engine temperature for performance and efficiency. The system uses a rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it’s needed to warm up the engine to reduce friction and heat the cab, or cools when needed for high power operation.
      An electric water pump — a first for Chevy trucks — supports the Active Thermal Management system and further enhances the engine’s performance and efficiency by eliminating the parasitic drag that comes with a conventional engine-driven water pump.
      Direct fuel injection is used to optimize efficiency and performance. With direct injection, a higher compression ratio (10.0:1) is possible because of a cooling effect as the injected fuel vaporizes in the combustion chamber, reducing the charge temperature and improving resistance to spark knock. Direct injection also enables gas scavenging from the combustion chamber to the turbo for fast response.
      Dual overhead camshafts contribute to the 2.7L Turbo’s smoothness and high output, with dual independent continuously variable valve timing working with the valvetrain to deliver optimal performance and efficiency. The dual independent system, which allows the intake and exhaust valves to be phased at different rates, promotes linear delivery of torque with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement) without sacrificing overall engine response or driveability.
      An integrated exhaust manifold on the cylinder head assembly promotes faster engine warmup and quicker turbo response.
      Oil jets located in the block are employed for performance and temperature control. They target the underside of the pistons and the surrounding cylinder walls with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more power and enhance long-term durability.
      Stop/start enhances fuel economy in city driving. The driver-selectable system shuts off the engine at stoplights and certain other stop-and-go situations, saving fuel. The engine automatically restarts when the driver takes their foot off the brake.
      The all-new 2.7L Turbo is matched with a Hydra-Matic eight-speed automatic transmission featuring enhancements designed to improve shift quality, as well as a new centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness.
      The all-new 2.7L Turbo will be built at the General Motors Spring Hill facility in Tennessee.
      The 2019 Silverado goes on sale this fall. EPA fuel economy estimates and towing/payload capacities are not yet available and will be announced closer to launch.

      Chevrolet has spilled a bit more information on the upcoming 2019 Silverado's powertrain lineup. The big story is a new turbocharged 2.7L four-cylinder becoming the base engine for the volume LT and new RST trims. We'll give you a moment to work through the shock that you're most likely experiencing.
      The 2.7 is rated at 310 horsepower and 348 pound-feet of torque. The torque figure is impressive when you consider that the 4.3L V6 (now relegated to the W/T, Custom, and Custom Trail Boss trims) produces 22 percent less torque. 0-60 mph is said to take under seven seconds. This engine can also run on just two cylinders. No word on fuel economy, but we wouldn't be surprised if this engine is close to the top in terms of the Silverado's powertrain lineup.
      The complete list of powertrain options available on the 2019 Chevrolet Silverado
      4.3L V6, 6-Speed Automatic: 285 horsepower and 305 pound-feet of torque Turbocharged 2.7L 4-Cylinder, 8-Speed Automatic: 310 horsepower and 348 pound-feet of torque 5.3L V8, 6- or 8-Speed Automatic: 355 horsepower and 383 pound-feet of torque 3.0L Turbodiesel I-6, 10-Speed Automatic: TBD 6.2L V8, 10-Speed Automatic: 420 horsepower and 460 pound-feet of torque “A major focus of the next-generation Silverado is expanding the range of choices. With all-new engines and a broader model range, there’s a Silverado for everyone, whether you’re buying your first pickup or your tenth,” said Tim Asoklis, chief engineer for the Silverado 1500.

Typically, a long stroke can increase the load of the pistons against the cylinder walls, generating more friction. That’s alleviated in the 2.7L Turbo with an offset crankshaft. It is slightly off-center of the cylinders, allowing a more upright position for the connecting rods during their movement.
      To support the high cylinder pressures that come with turbocharging, the crankshaft and connecting rods are made of forged steel and the pistons are made of a tough aluminum alloy with a cast iron ring groove insert.
      All elements of the 2.7L Turbo were designed for the demands of turbocharged performance in a truck environment, and the engine was subjected to the same rigorous durability standards as the Silverado’s proven V-8 engines.
      The 2.7L Turbo features an aluminum block and cylinder head for reduced mass.
      Unique valvetrain offers more precise control
      The 2.7L Turbo’s valvetrain is GM’s first to incorporate variable lift, duration and Active Fuel Management to optimize performance and efficiency across the rpm band. It is a key reason the engine’s peak torque is available at only 1,500 rpm.
      The system’s electro-mechanical variable camshaft effectively allows the engine to operate with three different camshaft profiles, complementing the variable valve timing system to deliver optimized operating modes for different engine speeds and loads:  
      High valve lift for full power. Low valve lift for balance of power and efficiency. Active Fuel Management shuts down two of the cylinders in light load conditions to further conserve fuel. “It’s like having different engines for low- and high-rpm performance,” said Sutter. “The camshaft profile and valve timing is completely different at low and high speeds, for excellent performance across the board.”
      The camshaft design alters the lift of the intake and exhaust valves. As the engine load changes, electromagnetic actuators allow a movable shaft containing different cam lobes to shift imperceptibly between high-lift and low-lift profiles.
      Lift is the distance the valve travels from its seat when opened, and duration is the amount of time the valve remains open. Higher lift and longer duration allow more air to flow into the combustion chamber, so the system’s high-lift lobe profile enhances performance at higher rpm, while the low-lift profile optimizes efficiency at low- and mid-range speeds.
      Dual-volute turbocharger builds torque
      The 2.7L Turbo engine employs an advanced dual-volute turbocharger that elevates the performance and efficiency advantages of a conventional turbo, with quicker response and enhanced low-rpm torque production.
      Rather than a single spiral chamber (volute) feeding exhaust gas from the exhaust manifold to drive the turbine on the turbocharger, the dual volute design has a pair of separate chambers with two exhaust gas inlets and two nozzles to drive the turbine. The design allows the exhaust pulses of the engine to be leveraged for faster spool-up and subsequent boost production, particularly at low rpm, where the effect significantly enhances torque output and drivability.
      It works in unison with the engine’s integrated exhaust manifold/turbocharger housing, which splits the exhaust channels from the cylinder head so the exhaust flows through two separate channels in the turbo housing, based on the engine’s exhaust pulses. When complemented by the precision of the engine’s valvetrain, that separation leverages exhaust scavenging techniques to optimize gas flow, which decreases exhaust gas temperatures, improves turbine efficiency and reduces turbo lag.
      An electronically controlled wastegate and charge-air cooling system support the turbocharger and enhance its effectiveness. Compared to a conventional wastegate, the electronically controlled version offers more precise management of the engine’s boost pressure for smoother, more consistent performance.
      With the charge-air cooler, the pressurized, heated air generated by the turbocharger is pumped through a heat exchanger before it enters the engine. That lowers the air charge temperature by about 130 degrees F (74 C), packing the combustion chambers with cooler, denser air that enhances power production. The system achieves more than 80 percent cooling efficiency with less than 2 psi (12 kPa) flow restriction at peak power, contributing to the engine’s available torque production at low rpm.
      Additional features
      A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump.
      Active Thermal Management helps the engine warm up faster and achieve its optimal engine temperature for performance and efficiency. The system uses a rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it’s needed to warm up the engine to reduce friction and heat the cab, or cools when needed for high power operation.
      An electric water pump — a first for Chevy trucks — supports the Active Thermal Management system and further enhances the engine’s performance and efficiency by eliminating the parasitic drag that comes with a conventional engine-driven water pump.
      Direct fuel injection is used to optimize efficiency and performance. With direct injection, a higher compression ratio (10.0:1) is possible because of a cooling effect as the injected fuel vaporizes in the combustion chamber, reducing the charge temperature and improving resistance to spark knock. Direct injection also enables gas scavenging from the combustion chamber to the turbo for fast response.
      Dual overhead camshafts contribute to the 2.7L Turbo’s smoothness and high output, with dual independent continuously variable valve timing working with the valvetrain to deliver optimal performance and efficiency. The dual independent system, which allows the intake and exhaust valves to be phased at different rates, promotes linear delivery of torque with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement) without sacrificing overall engine response or driveability.
      An integrated exhaust manifold on the cylinder head assembly promotes faster engine warmup and quicker turbo response.
      Oil jets located in the block are employed for performance and temperature control. They target the underside of the pistons and the surrounding cylinder walls with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more power and enhance long-term durability.
      Stop/start enhances fuel economy in city driving. The driver-selectable system shuts off the engine at stoplights and certain other stop-and-go situations, saving fuel. The engine automatically restarts when the driver takes their foot off the brake.
      The all-new 2.7L Turbo is matched with a Hydra-Matic eight-speed automatic transmission featuring enhancements designed to improve shift quality, as well as a new centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness.
      The all-new 2.7L Turbo will be built at the General Motors Spring Hill facility in Tennessee.
      The 2019 Silverado goes on sale this fall. EPA fuel economy estimates and towing/payload capacities are not yet available and will be announced closer to launch.

      We all know someone who takes things a bit a too far. In the case of automakers, that someone is EPA Administrator Scott Pruitt. Back in April April, Pruitt announced a serious rollback of fuel economy regulations that were set in stone during the Obama administration. In a summary of the proposed draft, the EPA would rollback the fleetwide average from 46.8 mpg for the 2026 model year to around 37 mpg - the fleetwide average for the 2020 model year. The draft also mentions pre-empting "California's authority" on setting their own emission standards under the 1975 Energy Policy and Conservation Act. This move has caused California and a collation of other states to file suit over the proposed changes.
      According to Automotive News, the changes proposed by Pruitt go a bit too far for automakers. All they wanted was the emission targets for the 2022-2025 model years to "ratchet up more gradually and offer more compliance flexibility." Now, they have to worry about litigation and uncertainty.
      "I don't think anybody in industry, when asked for reopening of standards, asked to level out to zero," said an unnamed lobbyist for a major automaker.
      However, certain groups argue that automakers should have expected something far-reaching under this current administration.
      "You've got to know your audience. If you go to [EPA Administrator] Scott Pruitt and Donald Trump and say you want relief from the rules and they are going to cost jobs, this is what you end up with," said Andrew Linhardt, deputy director of the Sierra Club's clean energy campaign.
      Later this week, executives from the major automakers will be meeting with officials at the White House to see if they can get the federal government and California to agree to some sort of comprise.

      When Chevrolet unveiled the Suburban and Tahoe RST last year, the Suburban seemed to get the short end of the stick. It didn't have the option of the 6.2L V8 that was available on the Tahoe. Chevrolet is fixing that for the 2019 Suburban RST.
      Available later this summer, the RST Performance Package for the Suburban brings the 420 horsepower 6.2 V8, 10-speed automatic, and magnetic ride control. We don't have a 0-60 mph time for the Suburban, but we're expecting to be a few tenths slower than the Tahoe RST with the same powertrain. Chevrolet does say the Suburban RST with the 6.2 can tow up to 8,100 pounds.
      “The RST Performance Package made its debut on the Tahoe RST last spring, and the response from our customers was overwhelmingly positive. In fact, Tahoe RST with the Performance Package is the fastest-turning Tahoe model, and we’ve received customer requests to offer the same performance and power to Suburban RST. Delivering on those requests with the Suburban RST Performance Package is another example of how Chevrolet has continually invested in the segment, developing models with combinations of capability, technology and performance to meet the needs of different customers,” said Sandor Piszar, director of Chevy Trucks Marketing and Advertising in a statement.

      2019 SUBURBAN RST PERFORMANCE PACKAGE BRINGS V-8 POWER AND STYLE TO CHEVROLET FULL-SIZE SUVS
      DETROIT — Chevrolet today announced the new Suburban RST Performance Package. Featuring a 420-hp, 6.2L V-8 engine, Magnetic Ride Control with performance calibration and a new Hydra-Matic 10L80 10-speed automatic transmission, the Suburban RST Performance Package brings a seamless blend of style and performance to Chevy’s portfolio of full-size SUVs.
      “The RST Performance Package made its debut on the Tahoe RST last spring, and the response from our customers was overwhelmingly positive,” said Sandor Piszar, director of Chevy Trucks Marketing and Advertising. “In fact, Tahoe RST with the Performance Package is the fastest-turning Tahoe model, and we’ve received customer requests to offer the same performance and power to Suburban RST. Delivering on those requests with the Suburban RST Performance Package is another example of how Chevrolet has continually invested in the segment, developing models with combinations of capability, technology and performance to meet the needs of different customers.”
      Available later this summer, this is the first time Suburban will offer the 6.2L V-8, which boasts 420 horsepower and 460 lb-ft of torque. The engine delivers three state-of-the-art technologies — direct injection, Active Fuel Management and continuously variable valve timing — to make the most of power, torque and efficiency across a broad range of operating conditions.
      Suburban RST will also feature a new 10-speed automatic transmission. Smaller steps between each ratio maximize engine power under acceleration. With a wide 7.39 overall gear ratio spread and lower numerical top gear ratio, the transmission also reduces engine revolutions at highway speeds.
      Magnetic Ride Control is an active suspension that “reads” the road every millisecond, triggering damping changes in the electronically controlled shock absorbers in as few as 5 milliseconds. As a result, the suspension delivers both improved body-motion control during cornering and a more comfortable ride while cruising. The new performance calibration included in the Suburban RST Performance Package increases body control for even higher levels of responsiveness and comfort.
      “When you want to hustle, the Suburban RST with the Performance Package offers high levels of acceleration, braking and road-holding grip,” said Eric Stanczak, chief engineer for Chevrolet full-size trucks. “When you want to relax, it is very refined, with exceptional ride comfort and interior quietness.”
      Available performance accessories for Suburban RST include a custom tuned Performance Dual-Side Exit exhaust system designed, engineered and backed by Borla, with sleek exhaust tips that improve exhaust flow by 28 percent for enhanced performance and decreased fuel consumption. Borla, and not GM, is responsible for the safety, quality and warranty for this exhaust system.  An available performance brake package designed, engineered and backed by Brembo features massive front red six-piston, fixed aluminum calipers with brake pads clamping on larger-than-stock 410 x 32mm (16.1 inch x 1.3 inch) Duralife™ rotors coupled with an 84 percent increase in brake pad area and a 42 percent increase in rotor area to increase system thermal capacity. Duralife™ rotors feature a hardened surface to reduce corrosion.
      The Performance Package is available as an upgrade to the Suburban RST, which was introduced last year. Styling is based largely on trends in the aftermarket space — virtually all chrome trim has been eliminated for a sporty, street appearance. Changes include body-color grille surround and door handles; gloss-black grille and mirror caps; and black roof rails, window trim, badging and Chevy bowties. RST package also includes 22-inch wheels wrapped in Bridgestone P285/45R 22 tires.
      The Suburban RST is expected to boast a towing capacity of 8,100 pounds. Full performance metrics will be announced closer to launch.
      Chevrolet has been the best-selling full-size SUV brand for 43 consecutive years. Today, Tahoe is the top selling vehicle in the segment, and Tahoe and Suburban account for nearly one out of every two Full-Size SUV sales when combined. Tahoe and Suburban customers are also the most loyal owners in the segment, with 77 percent of owners replacing their full-size SUV with another Tahoe or Suburban.
