    General Motors: Ignore the Fuel Economy Figures on Turbo-Four Silverado and Sierra

      On paper, both Ford and Ram can give the engine a run for its money

    General Motors made a big deal about a new 2.7L turbo-four that would be available on the 2019 Chevrolet Silverado and GMC Sierra 1500. This engine promises more power, better towing, and improved fuel economy when compared to the 4.3L V6 engine. But when the official fuel economy figures came out, the engine became somewhat less impressive.

    The EPA rates the 2.7L turbo-four at 20 City/23 Highway/21 Combined for the 2WD variant and 19/22/20 for the 4WD variant. That isn't a huge improvement on the V6s found in the Ford F-150 and Ram 1500.

    • F-150 with 3.3L V6: 19/25/22 (2WD), 18/23/20 (4WD)
    • F-150 with 2.7L EcoBoost V6: 20/26/22 (2WD), 19/24/21 (4WD)
    • Ram 1500 with 3.6L V6: 20/25/22 (2WD), 19/24/21 (4WD)

    "If you're delivering on everything, and you're getting the same fuel economy, the question is, 'Why?' " explained Stephanie Brinley, principal automotive analyst at IHS Markit.

    Officials at GM say the EPA ratings don't tell the whole story on the new engine. Like a diesel engine, " fuel economy will be better in the real world than its predecessor and will at least match comparable V-6 models from competitors," they said.

    "I don't think we're done with the fuel economy piece yet," said Tim Herrick, executive chief engineer of GM's full-size trucks to Automotive News.

    "Don't look at the label. We're as good or better than them in every step."

    Unfortunately for GM people do look at the label.  

    And when ever people say "we beat the label" well maybe Ford or Ram beats their label too.

    Unfortunately, GM is competitive with the other brands as opposed to class-leading in the fuel efficiency department.  There are two ways to fix this: either cut weight (at least 700-1000 lbs.) or improve engine MPG.  Maybe that turbo 4cyl needs to be tuned better; alternatively maybe the 4.3 V6 was not as bad as rumored.

    just another probable point that the EPA cycle doesn't do a good job of showing real world gas use.

    and another that any company can claim the cycles aren't representative.

    It will be interesting to see how this engine option is accepted by the market.   Still seems like a radical idea to have a 4cyl in a full size truck..

    I have a 2016 F-150 2WD SuperCab with the 2.7L V6 engine. 325 hp and 350 torque. Extremely impressive engine. It really accelerates, and in mixed driving, I am getting 22 mpg just about every tankful. On straight highway driving, it get 26 mpg. The Ford 2.3L 4cyl turbo, set to go into the 2019 Ranger, is supposed to do even better than that, mpg-wise. So Chevy's 20 City/23 Highway/21 Combined for its 2.7L 4cyl turbo is just not gonna cut it -- certainly with me and likely with many other buyers.

    See if this gets beat up in the Forums much like the EcoBoost from Ford does for not giving the stated gas mileage. People are going to enjoy the boost and the gas mileage will suffer. Common sense, you cannot have both fuel efficiency and power fun. Nothing has given that not even electric.

    Takes power to move weight.

    I've never really understood the issue with that.. Even non-boosted cars, if you're putting your foot into it you get bad fuel economy.

    Its really weird for them to come out and pretty much say EFF what the EPA says.. because for a looooong time I've been saying the exact same thing because of how I drive.

    Fuel economy is a direct result of the vehicle's overall efficiency AND.. and this is HUGE.. the driver's driving style.. Take a driver like me and put me in a Chevy Volt or Prius .. expecting great fuel economy and U will be very disappointed. I DRIVE!!! and that's not some bull$h! BMW interface either. I used laugh my ass off when people would say the Corvette was a very efficient vehicle to drive daily.. I was like "shiiiiiiiid.. not if U out here doing 0-60 in 3.6secs.. or constantly in the 90-110 range" On REAL.. I have driven my Yukon and seen 21mpg over a full tank interval... , but that was driving it like an old woman in mixed driving.. and for the NEXT trip I drove like I DRIVE.. and that fuel economy was like 15-16 mpg. (Mind U I tuned out the V4 mode when I bought it so its always in V8)

    Because it's hard to drive without putting your foot in it.  Stick a pebble in the turbo impeller and see how satisfying a 2.7 liter 4-cylinder Silverado is to drive. The boost is necessary even in average driving, and that is when you start to suck fuel.

      While the focus on the electric vehicles have been on the ultra plush and quick models from the likes of Tesla, Audi, and Jaguar, there is a lot of work being done for electric delivery vans. The combination of reduced maintenance, low fuel costs, and an abundance of torque to deal with heavy loads make them a perfect to do deliveries in urban areas. Rivian is the most-well known player here with plans to build out a fleet of electric vans for Amazon. Another player is ready to join the fight.
      Reuters reported yesterday that General Motors is working on a electric van for the commercial market. Five sources reveal that the van - codenamed BV1 - is expected to go into production late next year. It is expected to use Ultium battery technology that GM first talked about back in March. Utilizing this could solve one of the big issues with EVs, price. By switching Cobalt (expensive) for Aluminum (less expensive), GM says it will drop the cost of a battery to $100 per kilowatt-hour - making it around the same cost as regular gas powered van. Analysis done last year put the kilowatt-hour cost of a battery at $159. 
      One item still being debated internally is whether the van will be sold as Chevrolet, GMC, or a new brand. 
      When asked by Reuters, GM said it is “committed to an all-electric future and is implementing a multi-segment, scalable EV strategy to get there. At this time, we do not have any announcements to make regarding electric commercial vehicles.”
      GM isn't the only company getting on the electric van train. Ford has announced plans for an electric version of the Transit to launch in 2022, and British startup Arrival which has the backing of Hyundai, currently has an order of 10,000 vans from UPS.

      This week, Hagerty obtained a document from General Motors' executive director in charge of program management, Michelle Braun that says development on future car and truck programs has been paused due to the COVID-19 outbreak. But the document also mentions some intriguing information on upcoming powertrains for the C8 Corvette. Here are the details,
      Corvette Z06: 5.5L DOHC V8 known as the LT6 that will produce 650 horsepower and 600 pound-feet of torque. No mention of any type of forced-induction. Corvette Gran Sport: 6.2L OHC V8 with a hybrid system that's expected to produce 600 horsepower and 500 pound-feet of torque. Corvette ZR1: Twin-Turbo 5.5L DOHC V8, dubbed LT7. Output is expected to be 850 horsepower and 800 pound-feet. Corvette Zora: The powerhouse of the C8, it will take the Twin-Turbo LT7 and augment with a hybrid system. This is expected to produce 1,000 horsepower and 975 pound-feet of torque. Hagerty's report says the rollout of the new engines will begin in 2022 with the LT6, but the COVID-19 outbreak may push the plans back.

      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.

    • Probably a darned fine little car.  
    • Seems the incompetency of DC leadership is finally being checked. The IG of the EPA is starting an in-depth review of the process that the current administration took to relax emissions and MPG on the auto industry as it would seem it did not pass the required law for transparency as well as due process. As such, the changes at the EPA could all be rolled back to what they were before the changes were signed by Potus decree. https://www.epa.gov/sites/production/files/2020-07/documents/_epaoig_notificationmemo_7-27-20_fuel-efficient.pdf
    • Interesting to see how people seem to think there are no lower priced EVs when there are. The big issue is that most people do not want the base EVs, they want the fully loaded all the bells and whistles and as such, we are not seeing those sell. I agree that as the charging networks expand and prices come down, that we will see more adoption of the lower maintenance longer lasting EVs over the high maintenance ICE auto's. I also agree with you that the whole push for ICE auto's with 3 banger motors is a joke. Turbo all they want, the life of those engines are going to be short.
