    Chevrolet Silverado Diesel Gets 33mpg Highway

      ...Besting EPA results from Ford and Ram...

    Once the diesel rolls out for the 2020 Silverado, it will take the title of most fuel efficient full-size truck on the market with an EPA rating of 23 City / 33 Highway / 27 Combined.  The 3.0 liter inline six-cylinder diesel generates 277 hp and 460 lb-ft of torque.  The diesel is mated to a 10-speed automatic transmission and also features a start stop system.  In the Silverado, the price of the diesel engine is the same as upgrading to the 6.2 liter gasoline V8. It adds, $2,495 to the price of an LTZ or High Country model, or $3,890 to the cost of an LT or RST. Naturally, the engine will be available in the GMC Sierra as well. For those counting, this means the Sierra diesel is more efficient than the 4-cylinder diesel in the Chevy Colorado and GMC Canyon. It is also a less costly upgrade than on the two smaller trucks, there costing $5,745 on an LT

    GM is likely to hold the MPG title for a while as Ford's F-150 diesel was just released for 2019 and is rated for 22 City / 30 Highway / 25 Combined.  Ram hasn't sold their 3.0 V6 Ecodiesel since 2017, but it was rated at 20 City / 27 highway / 23 combined. 

    Honda does not field a full size truck. Nissan does, but does not offer a diesel in their standard duty models. Toyota does not offer a diesel at all, though it is rumored that the next Tundra will be coming with a twin-turbo V6 hybrid

    The Silverado Diesel arrives in dealerships this fall.

    This is awesome and should spark interest for those that pull a boat or RV. Way to go GM! :)

    27 combined sounds awesome, even if you don’t tow; MPG & longevity. A 1500 3.0TD CC would be my top choice by far.

    Those numbers are simply amazing for a full-size truck. Hell, those would be great for a mid-size truck. 

    There haven't been test for this yet, have there? I hope it isn't as slow as the Ram. I don't think it would be as it's more powerful on a much lighter truck. If it's a 15.5 second 1/4 mile truck(or better), that would be freakin' great. 16.0 is about the bare minimum, imo.

    So when will GM put this diesel in the Colorado/Canyon twins?

    Probably never. It is likely too long to be mounded in there.  I don't see how they'd fit another two cylinders in there.

    I gotta say, for the little amount they are charging for the upgrade to diesel.  As long as you're not looking for raw speed, the diesel might be the best choice of engine for this truck. 460 lb-ft of torque plus a 10-speed should still hustle it along pretty good.

    great job Chevy.  The farmers I know love the chance to use diesel in their pickups since they have diesel tanks on their farms.

    One issue with diesels in the US....states like mine put biodiesel requirements in play.  Some diesels do not take to these biodiesel fuels well.  My friend had bought a Nissan Titan diesel and returned it because of the issues with the Titan engine and biofuel.  I hope GM has made this diesel compatible with these mandatory biodiesels.

    That is outstanding and I always felt like 30 mpg on a truck was the magic number to hit to stand out, 23/33 mpg is like 4-cylinder Malibu numbers from 10 years ago so we have advanced a long way.   This does make the Silverado stand out.  I think the Silverado has some issues in the looks department which are costing it sales though.

    I don't know, maybe with the 10-speed, the midsize twins with the 4 cylinder diesel could eke out a better MPG rating?

    Some people don't need or want full-size pickups.  Mid-size works great for them.

    Hard to believe the 33 MPG number.  Do beef curtains really enhance aero THAT much?  The truck is massive, some would say unnecessarily so, and brick-nosed.  But I do trust GM and their MPG testing.  33 MPG is for 2WD of course, with 4WD rated at 29 MPG.

    Still rather drive what I have.  Would have strongly considered diesel if it were available in a non-ZR2 extended cab.  Uncle says his neighbors are reporting 18 MPG with their crewcab ZR2 Duramax.

    So what would a Colorado get with the 2.0T or 2.7T and a mild hybrid system?  I bet either of those would top 30 mpg.

    GM, just like Ford and Ram have never been able to make small or mid size efficient trucks. GM would be best to make the mid size truck an EV at this point.

    What a lameass statement.  Clueless.  Would they intentionally wish to drop midsize truck sales by 98%?

    The base Tacoma has no power, I bet Toyota could put an Avalon Hybrid powertrain in there and make it just as capable and get over 30 mpg.

    GM already dropped midsize truck sales by 100%  in the 2/3 year gap between the 1st and 2nd gen Colorado/Canyon, so there is precedent. ;)

    What a lame ass counter statement but then again, that’s nothing new coming from a known anti-progress troll.

    Mileage and driving reviews of this diesel with the 10-speed are great...

    ...I wish GM spent half the time just putting the 10-speed with every powertrain, and spending the rest of the money they wasted with so many combos, to improve the rest of the truck.

    Here's the thing though. No one upgrades or pays more for a "better" powertrain. Enthusiasts and magazines do. No one else does. 33mpg will be a great marketing moneker. But diesels never sell here. Ever. And, even in the case of gas and "more power", no one buys them. Great time and energy spent on this one, but, unsure of the results.

    Not being negative, just factual. The rest will remain 5.3L's with the clunky needs to go away 8-speed, a few confused buyers ending up with the 2.7T, and 2 a year buying the 6.2L/10-speed. Too many combos. Diesel, GREAT. But go to a Ford lot...and see the old age, leftover diesel F-150's still sitting around. Great marketing...but buyers don't care.

    Hmm...

    Don't just chime in for the sake of it, surreal.  You know damn well it would never work, and it was posted purely to troll the thread.  "Progress" can only be termed as such when it actually changes something for the better.

    Yes and no.. The price of this is still significantly more than a mid-sizer. I think about the cheapest this can be had is about 43k(39k LT package + 3890) for 4WD or 40k for 2WD. A Colorado with the 3.6, LT trim, 4WD is 32K, 2WD is $28,400 so there is still a pretty significant price difference between the two that ~10k in fuel savings will roughly take..never years to pay off.

    FYI, I did extended cab configurations for both to find the cheapest builds.

    FWIW, LT, crew cab(because it isn't available in extended cab), Colorado, 4WD and 2.8 Duramax is 39k. I definitely think it just kicked the 2.8 to the curb. I don't see that selling for sh!t once these are on dealer lots.

    Ford also priced their F-150 diesels too high for people to make the jump.  I think GM did the right thing by keeping the diesel upgrade cost low.

      As we reported last month, Jeep is adding a diesel to the Wrangler lineup.  The 3.0-liter diesel will produce 260 horsepower and 442 lb-ft of torque and be paired only with the 8-speed automatic. Electronic Start-Stop is also standard issue. 
      As for how much it is going to cost, be prepared to shell out up to an additional $6,000 over the base model.  It breaks down like this:  $4,000 for the diesel engine + $2,000 for the automatic transmission.  All in all, it ends up being a $3,250 upgrade over a Wrangler with a Pentastar V6 and 8-speed automatic.   The diesel will only be offered in 4-door trims of Sport, Sahara, and Rubicon.  In the RAM 1500 with the same powertrain, highway fuel economy is rated for 30mpg. Expect the lighter but less aerodynamic Wrangler to match that once EPA numbers are finalized.
      Diesel Wranglers start down the production line in late November, but the order books are already open if you want to head down to the dealer and put your order in.

      General Motors is planing a range of updates for their full-size trucks starting in the 2021 model year, beginning with updated interiors. Also coming is a Silverado ZRX aimed to take on the likes of the Ford F-150 Raptor and the Ram 1500 Rebel.  The ZRX would come with an improved off-road suspension, special DSSV Dampers like on the Colorado ZR2, rear and front locking differentials, and improved approach and departure angles. 
      If Chevy uses the same recipe they did on the ZR2, the ZRX will likely also get unique front and rear fascias.  One thing that isn't changing though is the powertrain. It's rumored that the ZRX will continue to use the same 6.2 liter V8 with 420 horsepower and 460 lb.-ft of torque.  This is disappointing as the Raptor and Rebel TRX both get more powerful engines than their on-road counterparts. 
      If these plans come to fruition, expect the Silverado ZRX to come out in 2021 as a 2022 model.

      General Motors announced a recall Wednesday of 3.46 million GM trucks and SUVs for a braking issue that has been linked to 113 accidents and 13 injuries.  The problem arises from a vacuum pump issue where the pump make less vacuum over time, thereby increasing the braking effort. The pump is lubricated by engine oil and can accumulate debris and oil sludge lessening the pump's effectiveness.
      The recall covered model years 2014 - 2018 of Cadillac Escalade, Chevrolet Silverado, Suburban, and Tahoe, and GMC Sierra and Yukon. 
      GM told the NHTSA that the pump design was only used during those years of manufacture. 
      In a smaller recall, GM is recalling 177,000 2018 Chevrolet Malibus with the 1.5-liter Turbo engine where an error in the engine control computer could disable the fuel injectors.
