GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.

2022 Chevy Suburban, Tahoe, GMC Yukon, Cadillac Escalade up another $1,600

The 2022 Chevrolet Tahoe and Suburban, the 2022 GMC Yukon and the 2022 Cadillac Escalade have all gone up by $1,600. The GM profit and loss department added $1,500 to the MSRP for each of the full-sized SUVs and $100 to their destination charges, that destination fee now $1,795 for each vehicle. It's not an inconsequential bump; however, considering where the trucks were priced at launch, and everything that's happened since, the latest retail prices don't seem that bad. Take the Suburban — in February 2020, Chevrolet practically carried over pricing for the truck with a revamped interior and independent rear suspension, starting it at $50,295 after destination. After this latest increase, the 2022 Tahoe LS in two-wheel drive costs $55,590, after destination.  The delta between the 2021 Suburban at launch in March 2020 and the current model is a little grander compared to the Tahoe, like the SUV itself. Back then, it started at $52,295, the same price as the outgoing model. After this third price increase in the past year, the 2022 Suburban LS in 2WD starts at $61,290 after destination. GM Authority says the 2023 Tahoe and Suburban are reportedly headed down production lines in the middle of July. The biggest addition to both models will be the availability of Super Cruise, which is already available on the sister SUV, the Cadillac Escalade. The hands-free driving assistance feature can only be optioned on the Premier and High Country trims. It costs $2,500 to put Super Cruise on the Escalade. GM hasn't divulged the feature's price yet for the Chevy twins; that's likely to come when the automaker announces 2023 Tahoe and Suburban MSRPs, so beware of more potential price increases. After that, there's a heavy refresh planned for the 2024 model year, including a new instrument panel design that looks like it replaces the current gauge cluster with a large, freestanding screen.  The Yukon's entry-level price goes up to $57,590 for the SLE trim turning the rear axle.   The Cadillac Escalade's second MSRP bump takes it to $81,235 for the Luxury 600 trim in 2WD, and $84,235 for the extended ESV model in the same trim. The price creep hasn't stopped Escalades from pulling off dealer lots almost as soon as they're delivered, sales for the first quarter of the year totaling 10,505 units, trouncing domestic and foreign competition.

2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.
