It's the 9-Speed Automatics

Recommended Posts

THANK YOU Dwight!!!

This is very interesting information, so Ford then choose to write off the investment and go another route versus GM wanting to get money out of their investment and offer a rather pathetic power train.

These are the type of decisions that GM will end up hurting by. Yes it would be great if every dollar invested in R&D returned a profit, but sometimes, the best intentions means you throw it into the garbage bin and start over.

Very sad for sure, Hopefully GM will realize they need to offer something better. 

Put this in the Chevrolet's and bring in a proper Torque heavy Tranny!

The term for this type of behavior is the Sunk Cost Fallacy; go Google it.

But, I am not sure this is exactly true of GM's decision in this case. The 9-speeds do offer a few things -- better shift quality from one way clutches from gears 2-9 and smaller ratio steppings. The 6TXX trannies were very average boxes in this department. The new 9-speeds also have a pressure accumulator to prime the trannies for engine restarts with Start-Stop systems -- instead of having to spin the converter from stand still and pressurize the transmission fluid so the hydraulics will start working. The Accumulator stores pressurized fluids while the transmission is running and re-injects them during a restart. The only bad thing about the new 9As is that they are stuck at 280 lb-ft. which is OK for the LSY 2.0T and LGX 3.6 V6es. For high performance stuff, I guess GM is deferring to Longitudinal cars with the GM-Ford 10L80 and 10L90 transmissions good for 590 lb-ft and 650 lb-ft respectively.

That is great info to know and I wonder if that is what they are doing with this years XT5 that I had as a service loaner for a few days. The start / stop was barely noticable compared to earlier year versions.

Thank you Dwight, I love this type of learning. You made my day as I am still working so a break like this is very welcomed by me.

You Rock! :metal:

Interesting.

But I just wanna put out another point of view. A hypothetical if you will. 

This engine is a successor to the one that is in the ATS, right?

I know for a fact that one (of many) issue many journalists had with the ATS, and undoubtedly folks coming from Audi or BMW was that the 2.0T in the ATS was not as refined as the one offered in a Bimmer or Audi. Wasnt smooth. (A common complaint for GM 4 cylinders since, like...forever.)  

Well, this transmissions, as per the OP, and Ford apparently, is that it makes the LSY a refined powerplant.

Ford may not have had use for it because the refinement improvements alone did not justify the costs and weight increases for their Ford branded vehicles, but seeing GM kept it for their Cadillac small CUV, maybe GM and Cadillac engineers decided that refinement was an upmost  priority and since an XT4 doesnt really need tire melting torque to convince people to buy it, but silky smooth driving dynamics to lure folk from the German brands, then perhaps it was a wise decision?

Because that is how I choose to view this decision.  Because quite honestly, 237 horsepower and 258 ft.lbs of torque for a cute ute CUV in a segment that really doesnt care for power, nor would they understand it or feel or even want it, is good enough.

And here I was, trying to find out what the XT4's competition is with a Car and Driver article that tested it that usually also mentions the competition, and the first thing in the title is:  The 2019 Cadillac XT4 Is More Smooth Than Sporty

They follow that up with: 

Cadillac continues to bifurcate its lineup into sporty sedans and milquetoast crossovers.

https://www.caranddriver.com/reviews/a23143999/2019-cadillac-xt4-crossover-drive/

 

But...crossovers, especially little shytbox crossovers like these, ARE NOT ABOUT SPORTY...despite what some of us want to believe...

And after looking at the competition's numbers, Porsche, Volvo, Alfa Romeo...all 3 have more HP and torque...but... like I said...crossovers, especially little shytbox crossovers like these, ARE NOT ABOUT SPORTY...despite what some of us want to believe...

This is what Car and Driver said:

 

Quote

 

Sure, it's too bad that the honey of an engine, which revs so smoothly you'd swear its cylinder liners were spun silk, must work through a transmission that positively neuters its output with lackadaisical responses. But the competent yet uncommunicative suspension and steering? That's par for this class. The rest of the baby Caddy's package has plenty of good stuff to look forward to.

Fresh Powertrain

The XT4's new engine, for starters, makes a good first impression. Producing 237 horsepower at 5000 rpm and 258 lb-ft of torque from 1500 to 4000 rpm, this turbocharged 2.0-liter inline-four is so smooth and quiet we found ourselves regularly checking the tachometer to see if it was running. And even at full throttle, it is almost disconcertingly quiet and vibration free. Cadillac's estimates of a 7.0-second zero-to-60-mph time with front-wheel drive (and 7.2 for AWD models) are only midpack for this segment, but turbo lag is virtually unnoticeable. The engine—code-named LSY—weighs 15 pounds less than the 2.0-liter four used elsewhere in Cadillac's lineup, 

 

 

 

 

 

Steering and suspension response is uncommunicative...par for the class. Porsche and M-B and BMW and Alfa Romeo is well represented...

Midpack for performance times vis-a-vis the competition, in a segment that doesnt give a phoque about performance...despite Porsche and Alfa Romeo and BMW...in this segment...and  an anemic XT4 is STILL midpack in performance times...BUT...ITS SMOOTH AND QUIET!!!

Something that 4 cylinder GM cars NEVER were...and THIS is a Cadillac, where smoothness and quietness IS A MUST!!!  For the FIRST time in like...forever!

 The 2019 Cadillac XT4 Is More Smooth Than Sporty

The LSY (2.0T) and L3B (2.7T) are from the same (new) family of GM Tri-Power Inline-4 engines. They are a clean sheet designs which boasts a 3-stage cam switching valve train with dual continuous cam phasing. The cam switching system works by having 3 cam lobes for each intake valve on a sliding sleeve. There are four -- one for each cylinder -- on the intake cam. A pair of solenoid actuated pins acting on grooves in the sleeve commands the sleeve to slide back and forth on the camshaft. The switching can only occur when the valves' roller followers are on the base circle (zero lift). On the current implementation the three profiles are -- zero lift (cylinder deactivated), low lift and high lift. On the exhaust cam there are only two sleeves; for the two cylinders that can be deactivated. There are only two positions on the exhaust cam sleeves -- zero lift (deactivated) and regular lift. In addition to switch between cam profiles, the engine also has variable cam phasing (valve timing) which can advance and retard both the intake and exhaust camshafts. There are a total of 6 cam lobe switcher solenoid assemblies atop the valve covers. Unlike previous VVT phasers, the new ones park in the middle rather than one end of the variation range. The engine blocks are webbed for higher rigidity and feature a water cooled integral exhaust collector which terminate in a single divided outlet designed exclusively to support the use of a twin scroll turbo bolted directly to the cylinder heads. There is no exhaust headers. The engines are balanced by two counter rotating Lancester balance shafts in the oil sump. The aluminum block is of the deep skirt design with an integral girdle structure rather than a bolt on main bearing reinforcement. The engines only support direct injection and feature a revised oil separator and collector under the valve cover for the PCV system to minimize intake port fouling. If you know what a PCV oil catch can looks like, look for it on the top of the engine in the 2nd video @ ~ 6:52 on the top right of the frame. The engine also features advanced coolant and oil thermal management for fast warm up and the water pump is electric which decouples water pump speed from engine speed and allows continued full coolant movement even when the engine is shut down protecting the turbo and the engine from oil coking.

AWESOME, Thank you again @dwightlooi, This has been a great evening of working my job and learning some new stuff on new auto's. 

Very cool informative videos!

Question for you, with the complexity of these engines and the various cam phases, what do you think the engine life will be if the basic maintenance is done?

  • 250,000 miles
  • 350,000 miles
  • ??????

Appreciate your take on the engine life of these new designs.

The new 2.0T in the XT4 is disappointing when the dealership across the street selling Denali Terrains has a much more powerful and faster 2.0T.

I have no idea. Ask me in 15 years... LOL!

But, certain design decisions potentially increases the failure probabilities. For example, a electric water pump may fail to operate because its motor failed independently of the engine, whereas a traditional water pump will turn if the engine is still turning. Sure, the impeller can break and the engine itself can fail, but that applies to both electric and crank driven pumps. Motor failure is a new failure mode exclusive to an electric water pump. The cam switching system is also NOT a safe-in-fail. If the pin solenoids fail it is possible for the switcher to be stuck between lobes which will be a damaging event. Again, engines have adopted design decisions that are not safe-on-fail before... the most common being interference valve actuation. Should the timing belt of chain break, the piston will smash into the valves and grenade the engine. But that is almost universal today and I haven't heard of chains breaking. Active oil and coolant flow management also presents the possibility of solenoid failure cutting off the engine from the coolant and oil radiators which will be leave you on the side of the road, whereas traditional thermostat failure will simply be a emissions event from the engine not ever reaching the optimum operating temperatures.

Not for long... the LTG is not long for this world. BTW, the LTG in the Terrain was also detuned to 252 hp (from 275 hp) and 260 lb-ft (from 295 lb-ft). Again, because the 2018+ Terrain picked up the 9T50 9-speed Automatic.

Anyway... I suspect that GM will have a high output Tripower Four at some point, just not for the Transverse FWD  cars.

I'll like to see a 2.7T High Output 4-cylinder probably around 450 bhp @ 5,700 rpm, 420 lb-ft @ 2,600~5,600 rpm, rev limited to 6,200 rpm. This will pair quite well with the 10L80 10-speed automatic transmission and it will be a true V8 replacement 4-potter. It'll be more than good enough for a CT4-V. Maybe even an XT4-V if GM will buy Ford's 8-speed Auto.

Yeah. They haven't released the specs for the CT5 yet.  That is coming with the 10-speed RWD paired with the 2.0T, so hopefully it will be a much higher output version of the same engine.

So the really smooth 9AT coupled with a smooth and quiet 2.0T engine in a FWD luxury crossover lacks the performance punch a lot of people here expected.  Good to know.  When my '08 Lucerne was being serviced, I asked a salesman about the new Terrain.  We looked at a loaded SLT and he mentioned how quiet the engine was and the lack of turbo lag and the smooth ride.  What the salesman told me corroborates with what dwightlooi mentioned here.  For the FWD crossovers, the demand is for smooth-running quiet fuel-efficient four-cylinder engines.  This setup matches what is required. This is what most people want in their powertrain.

Now as for the CT5 and any RWD sedans that get the 2.0T or the 2.7T, I do not see the current 9AT installed in such a performance car since there would be too little torque available for those engines.

However the Buick envision now had 295lb torque from the 2.0 and its 9 speed.  So which 9 speed is it using or is it not a GM transmission. 

  • 9T50   -- 258 lb-ft
  • 9T65   -- 280 lb-ft

By the way I have a Terrain Denali and the 2.0 is plenty of powerful for it.  Everyone that has drove it thinks it has a v6.  These don't need super powerful engines

If it's the 9A it's probably the 9T65. It can work if they limit boost in 1st gear to moderate the input torque when the greatest amplification happens. 280 is not that far from 295. The Focus ST did that in 1st (back then) too. You can't responsibly drop in the 348 lb-ft 2.7T or th 368 lb-ft 3.6TT engines on the 9T65 like you could the 6T80 though.

GM doesn't have a longitudinal 9A. They have the 8L45, 8L90, 10L80 and 10L90 with 8 or 10 speeds.

Seems like a typical GM move, and why Cadillac is where they are. 

I don't see why they don't make a better FWD transmission that can handle over 300 lb/ft with 8-9 gears or whatever they deem they need.

No need for speed in this segment.  Its just a cute ute CUV. 

Define better transmission?

Because as I understand it, this 9 speed is smooth and makes this 4 cylinder rev even smoother. 

I know Drew mentioned that the Denali Terrain has got more power, but as much clout as a Denali has got,  its still not a Cadillac. And Im willing to bet that the Denali aint as smooth as the XT4 is said to be...

If you are gonna blast Cadillac for something, blast Cadillac for even being in this segment to begin with...

While I did say a couple of weeks ago if they are to do a vehicle this small, then they should go all in, but I also said that I wouldnt want any Cadillac to be in a 40 000 dollar price range. I would want Cadillac to START in the 55 000 dollar range. And therefore a XT4 better be a V trimmed CUV...

But as is...we all could moan about the XT4 not being a tire melting Hellcat beating motor vehicle, to my understanding, the XT4 is one smooth and quiet ride. And THAT would and should  be the main focus here. And I think it was wise for Cadillac to choose smooth and quiet over unnecessary torque figures and risking having a ride that some Euro loving badge snob complain about how harsh the engine or ride is! 

Its a Cadillac after all. No...not a V Series Cadillac. Just a luxury ride Caddy!

Cadillac issues aside, GM probably doesn’t have any transverse mounted engine with over 300lb-ft other than the soon to be dead XTS V-sport.  So if they made one 9-speed transverse mount transmission it could be used in everything from a Sonic to a Traverse .  Better economies of scale that way.

Then in rear drive maybe you have a couple torque ratings for a regular duty and the high torque outputs.

The older GM 2.0 is a good motor, and so is the new one.  But the new one is new, which means unproven, and it is slower.

It's fast enough in the XT4 for volume models.  They will want to look at getting a higher tune of that motor as an option.  It is smooth once up to speed, and sporty but it is not blazing quick.  It's like a 7-7.5 second to 60 car.  I am certain it will cruise well on the highway.

The CT6 base 2.0 through 2018 had the old 2.0.  When they swapped in the new one for 2019, it lost a second of 0-60 time...i.e. slower.

I thought the CT5 just announced was getting the older 2.0?  I don't think the new one is slated for the CT5, yet.

The 2020 Acadia gets the new 2.0 as an option.

I really am jazzing on a Regal, and probably a TourX.  The AWD tourX is slower by a bit with the 8 speed instead of the FWD 9 speed sportbacks but maybe that's a good thing.  Sounds like the 8 speed tranny might handle power and torque better.  Having the older proven 2.0 may be a good thing.

Not exactly... Unlike the difference between transverse and longitudinal transmissions -- which are totally different animals -- there is no substantial difference between a lengthwise or sideways engine installation. We are talking about a different exhaust pipe, new air box and new dress cover. The last being largely cosmetic (so the lettering don't don't face the wrong way). 99% of the engine is identical. The differences are minute enough that GM doesn't even have separate RPO codes for transverse and longitudinal versions of the same engine. The FWD and RWD 3.6TT are both the LF3. The FWD and RWD 3.6 NA are both the LGX or LFX. The FWD and RWD "old" 2.0Ts are both LTG.

The EPA ratings went from 22/25/30 to 24/28/34 MPG (US) with the new 2.0 and 10-speed automatic, which is more useful in the real world (along with improved NVH characteristics) than ~6 vs ~7 seconds 0-60 MPH.

The mpg improvements particularly for a big car are impressive however losing that much acceleration for a luxury brand is concerning.

Not when there are 4 additional engine choices above that. 3.6, 3.0TT, 4.2TT, 4.2TT-V

7 seconds to 60 is fine for most people anyway. Someone buying a base base base CT6 isn't going to be concerned with 0-60, they're going to be concerned with heated seats.

      On Wednesday, General Motors invited a number of media to their tech center in Warren, MI for their EV Day event. The company is making a big bet on electric vehicles with 11 new vehicles rolling out by 2025, featuring a new electric modular platform and battery tech. Here's what we know.
      Third-Generation Electric Vehicle Platform
      Underpinning this massive push is GM's new third-generation EV platform (BEV3). The new platform was designed to provide flexibility for different vehicle types - ranging from compact cars to pickup trucks. Battery packs are designed to be mounted beneath the passenger compartment to allow for a lower center of gravity. This results in more passenger room and improved handling. The platform also allows for different drive configurations - front, rear, or all-wheel drive - depending on the vehicle.
      Ultium Battery Technology
      Providing the electric power for these new models is what GM calls Ultium batteries. Working together with its battery partner LG Chem, the Ultium batteries are large-format, pouch-style cells that can either be stacked vertically or horizontally in packs. This will allow more flexibility for engineers to design battery packs for vehicles.
      More important is the chemistry of the batteries. GM has reduced the amount Cobalt - an element used in the making of batteries that is becoming harder to find and expensive - by seventy percent. Instead, the batteries are using aluminum. This will hopefully bring down the price of the battery packs.
      Battery capacity will range from 50 to 200 kilowatt hours - giving a projected max range of 400 miles depending on the vehicle. Level II and DC fast-charging are both supported.
      The Vehicles
      At the event, GM had 10 vehicles on display and one shown via digital renderings. The current plan is to start launching the new models beginning later this year.
      Updated Chevrolet Bolt: The first vehicle to be launched in this offensive. It will get an updated interior with a more premium dash. Chevrolet Bolt EUV: The crossover-variant of the Bolt, it is about five-inches longer and rides on a wheelbase that has been stretched by three inches. An updated roofline reportedly eliminates the small front windows on the Bolt. The EUV will also be the first model outside of Cadillac to get Super Cruise. Chevrolet Midsize Crossover: About the same size as the Blazer, this model has an aggressive design and features a low roofline. A pair of 18-inch multimedia displays dominate the interior. Chevrolet Full-Size Truck: This was the model only shown in digital renderings according to those who were at the event. It will complement the Silverado and be aimed at those who want something to be used on a job site - not like the upcoming GMC Hummer Truck or Rivian which are aimed more at lifestyle folks. This model is expected to arrive in 2025. Buick Crossover and SUV: These two models didn't have a name and were wearing a design that was described by the Detroit Free Press as a "vaguely European look".  GMC Hummer Truck: This will only be available in a crew-cab configuration with a five-foot bed. The design will be utilitarian and boxy. Inside, two large screens will serve as the instrument cluster and infotainment system. Don't expect any leather as many of materials used inside will be made from recycled materials. The truck will also have removable roof panels (like the Jeep Wrangler, that can be stored in the front trunk. GMC Hummer SUV: Basically the same as the truck, albeit using a shorter wheelbase. Cadillac Lyriq: We have seen teasers of this model last year and Cadillac dropped another this week showing off the silhouette - reminding us some crossovers from Jaguar and Porsche. The vehicle is wide and rides on 23-inch wheels. Size-wise, it is similar to the XT5. The interior boasts a 34-inch-wide high-def screen and seating for four, though the production model may have seating for five. Cadillac Celestiq: A new four-door flagship sedan that has a long front end and a fastback rear according to those who saw the clay model. It will be hand-built and carry a six-figure pricetag. Cadillac Large SUV: About the size of an Escalade, it be complementary vehicle to it. The model will have a more traditional design than the other Cadillac EVs. Inside, it will boast large screens up front and three-rows of seating. Source: Roadshow, Detroit Free Press, The Drive, General Motors

      GM Reveals New Ultium Batteries and a Flexible Global Platform to Rapidly Grow its EV Portfolio
      WARREN, Mich. – Starting today, General Motors Co. (NYSE: GM) is gathering hundreds of employees, dealers, investors, analysts, media and policymakers to share details of its strategy to grow the company’s electric vehicle (EV) sales quickly, efficiently and profitably.
      “Our team accepted the challenge to transform product development at GM and position our company for an all-electric future,” said Mary Barra, GM chairman and CEO. “What we have done is build a multi-brand, multi-segment EV strategy with economies of scale that rival our full-size truck business with much less complexity and even more flexibility.”
      The heart of GM’s strategy is a modular propulsion system and a highly flexible, third-generation global EV platform powered by proprietary Ultium batteries. They will allow the company to compete for nearly every customer in the market today, whether they are looking for affordable transportation, a luxury experience, work trucks or a high-performance machine.
      “Thousands of GM scientists, engineers and designers are working to execute an historic reinvention of the company,” said GM President Mark Reuss. “They are on the cusp of delivering a profitable EV business that can satisfy millions of customers.”
      Ultium Batteries and Propulsion System Highlights
      GM’s new Ultium batteries are unique in the industry because the large-format, pouch-style cells can be stacked vertically or horizontally inside the battery pack. This allows engineers to optimize battery energy storage and layout for each vehicle design. Ultium energy options range from 50 to 200 kWh, which could enable a GM-estimated range up to 400 miles or more on a full charge with 0 to 60 mph acceleration as low as 3 seconds. Motors designed in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications. Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400-volt battery packs and up to 200 kW fast-charging capability while our truck platform will have 800-volt battery packs and 350 kW fast-charging capability. GM’s flexible, modular approach to EV development will drive significant economies of scale and create new revenue opportunities, including: 
      Continuous Improvement in Battery Costs: GM’s joint venture with LG Chem will drive battery cell costs below $100/kWh. The cells use a proprietary low cobalt chemistry and ongoing technological and manufacturing breakthroughs will drive costs even lower. Flexibility: GM’s all-new global platform is flexible enough to build a wide range of trucks, SUVs, crossovers, cars and commercial vehicles with outstanding design, performance, packaging, range and affordability. Capital Efficiency: GM can spend less capital to scale its EV business because it is able to leverage existing property, including land, buildings, tools and production equipment such as body shops and paint shops. Complexity Reduction: The vehicle and propulsion systems were designed together to minimize complexity and part counts beyond today’s EVs, which are less complex than conventional vehicles powered by internal combustion engines. For example, GM plans 19 different battery and drive unit configurations initially, compared with 550 internal combustion powertrain combinations available today. Rising Customer Acceptance: Third-party forecasters expect U.S. EV volumes to more than double from 2025 to 2030 to about 3 million units on average. GM believes volumes could be materially higher as more EVs are launched in popular segments, charging networks grow and the total cost of ownership to consumers continues to fall. New Sources of Revenue: By vertically integrating the manufacture of battery cells, the company can reach beyond its own fleet and license technology to others. The first generation of GM’s future EV program will be profitable. The initial programs will pave the way for further accretive growth. GM’s technology can be scaled to meet customer demand much higher than the more than 1 million global sales the company expects mid-decade.
      Upcoming Launches and Reveals
      Chevrolet, Cadillac, GMC and Buick will all be launching new EVs starting this year. The next new Chevrolet EV will be a new version of the Bolt EV, launching in late 2020, followed by the 2022 Bolt EUV, launching Summer 2021. The Bolt EUV will be the first vehicle outside of the Cadillac brand to feature Super Cruise, the industry's first true hands-free driving technology for the highway, which GM will expand to 22 vehicles by 2023, including 10 by next year.
      The Cruise Origin, a self-driving, electric shared vehicle, shown to the public in January 2020 in San Francisco, was the first product revealed using GM’s third generation EV platform and Ultium batteries. Next will be the Cadillac Lyriq luxury SUV in April. Details about its launch will be shared then. The reveal of the Ultium-powered GMC HUMMER EV will follow on May 20. Production is expected to begin in Fall 2021 at GM’s Detroit-Hamtramck assembly plant, GM’s first assembly plant 100 percent dedicated to EV production.

      On Wednesday, General Motors invited a number of media to their tech center in Warren, MI for their EV Day event. The company is making a big bet on electric vehicles with 11 new vehicles rolling out by 2025, featuring a new electric modular platform and battery tech. Here's what we know.
      Third-Generation Electric Vehicle Platform
      Underpinning this massive push is GM's new third-generation EV platform (BEV3). The new platform was designed to provide flexibility for different vehicle types - ranging from compact cars to pickup trucks. Battery packs are designed to be mounted beneath the passenger compartment to allow for a lower center of gravity. This results in more passenger room and improved handling. The platform also allows for different drive configurations - front, rear, or all-wheel drive - depending on the vehicle.
      Ultium Battery Technology
      Providing the electric power for these new models is what GM calls Ultium batteries. Working together with its battery partner LG Chem, the Ultium batteries are large-format, pouch-style cells that can either be stacked vertically or horizontally in packs. This will allow more flexibility for engineers to design battery packs for vehicles.
      More important is the chemistry of the batteries. GM has reduced the amount Cobalt - an element used in the making of batteries that is becoming harder to find and expensive - by seventy percent. Instead, the batteries are using aluminum. This will hopefully bring down the price of the battery packs.
      Battery capacity will range from 50 to 200 kilowatt hours - giving a projected max range of 400 miles depending on the vehicle. Level II and DC fast-charging are both supported.
      The Vehicles
      At the event, GM had 10 vehicles on display and one shown via digital renderings. The current plan is to start launching the new models beginning later this year.
      Updated Chevrolet Bolt: The first vehicle to be launched in this offensive. It will get an updated interior with a more premium dash. Chevrolet Bolt EUV: The crossover-variant of the Bolt, it is about five-inches longer and rides on a wheelbase that has been stretched by three inches. An updated roofline reportedly eliminates the small front windows on the Bolt. The EUV will also be the first model outside of Cadillac to get Super Cruise. Chevrolet Midsize Crossover: About the same size as the Blazer, this model has an aggressive design and features a low roofline. A pair of 18-inch multimedia displays dominate the interior. Chevrolet Full-Size Truck: This was the model only shown in digital renderings according to those who were at the event. It will complement the Silverado and be aimed at those who want something to be used on a job site - not like the upcoming GMC Hummer Truck or Rivian which are aimed more at lifestyle folks. This model is expected to arrive in 2025. Buick Crossover and SUV: These two models didn't have a name and were wearing a design that was described by the Detroit Free Press as a "vaguely European look".  GMC Hummer Truck: This will only be available in a crew-cab configuration with a five-foot bed. The design will be utilitarian and boxy. Inside, two large screens will serve as the instrument cluster and infotainment system. Don't expect any leather as many of materials used inside will be made from recycled materials. The truck will also have removable roof panels (like the Jeep Wrangler, that can be stored in the front trunk. GMC Hummer SUV: Basically the same as the truck, albeit using a shorter wheelbase. Cadillac Lyriq: We have seen teasers of this model last year and Cadillac dropped another this week showing off the silhouette - reminding us some crossovers from Jaguar and Porsche. The vehicle is wide and rides on 23-inch wheels. Size-wise, it is similar to the XT5. The interior boasts a 34-inch-wide high-def screen and seating for four, though the production model may have seating for five. Cadillac Celestiq: A new four-door flagship sedan that has a long front end and a fastback rear according to those who saw the clay model. It will be hand-built and carry a six-figure pricetag. Cadillac Large SUV: About the size of an Escalade, it be complementary vehicle to it. The model will have a more traditional design than the other Cadillac EVs. Inside, it will boast large screens up front and three-rows of seating. Source: Roadshow, Detroit Free Press, The Drive, General Motors

      GM Reveals New Ultium Batteries and a Flexible Global Platform to Rapidly Grow its EV Portfolio
      WARREN, Mich. – Starting today, General Motors Co. (NYSE: GM) is gathering hundreds of employees, dealers, investors, analysts, media and policymakers to share details of its strategy to grow the company’s electric vehicle (EV) sales quickly, efficiently and profitably.
      “Our team accepted the challenge to transform product development at GM and position our company for an all-electric future,” said Mary Barra, GM chairman and CEO. “What we have done is build a multi-brand, multi-segment EV strategy with economies of scale that rival our full-size truck business with much less complexity and even more flexibility.”
      The heart of GM’s strategy is a modular propulsion system and a highly flexible, third-generation global EV platform powered by proprietary Ultium batteries. They will allow the company to compete for nearly every customer in the market today, whether they are looking for affordable transportation, a luxury experience, work trucks or a high-performance machine.
      “Thousands of GM scientists, engineers and designers are working to execute an historic reinvention of the company,” said GM President Mark Reuss. “They are on the cusp of delivering a profitable EV business that can satisfy millions of customers.”
      Ultium Batteries and Propulsion System Highlights
      GM’s new Ultium batteries are unique in the industry because the large-format, pouch-style cells can be stacked vertically or horizontally inside the battery pack. This allows engineers to optimize battery energy storage and layout for each vehicle design. Ultium energy options range from 50 to 200 kWh, which could enable a GM-estimated range up to 400 miles or more on a full charge with 0 to 60 mph acceleration as low as 3 seconds. Motors designed in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications.

      General Motors will be bringing back the Hummer name to sell a new electric truck as part of the GMC lineup.
      The Wall Street Journal first broke the news yesterday with GM moving forward on plans to bring Hummer back that was first reported back in June. The report also said that the company would tout the return with a Super Bowl ad featuring NBA star LeBron James. GM declined to comment.
      The decision is likely due to the planned $3 billion investment for the Detroit-Hamtramck plant that we reported back in October. The investment is to gear up the plant to build an electric pickup for GMC and an electric Cadillac SUV by 2023. But in 2021, the plant will produce a "low volume BT1 pickup" under a different brand. At the time we speculated that it may be Hummer. This seems to lineup with the reporting done by the Wall Street Journal which says the truck will be similar in design to the Jeep Renegade.
      Bloomberg adds that there are plans for a large SUV for Hummer if the truck proves successful according to sources. The sources also say that the company is considering selling the new Hummer truck in existing dealers under the name of “Hummer by GMC.”

      It's not possible to message you.  At least, it wasn't possible to do that last summer.  So I'll post it here.  I had a crazy layover back in June at PHL ... for about 8 hours ... and wondered how far into NJ you were from Philly.  What I did is get the PHLash day pass and did the self-guided tour of Center City before heading back to the airport.  I stayed too close to the center because of time. I actually wasted time by going into South Philly.  I wanted to venture out onto the Main Line and see Villanova.  That rail line was included on the pass I bought.  I had to manage my time because of the late afternoon flight to the Coast.  Cheers.
