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.

Hotter Cadillac ATS-V+ could use LS7 power

Rumor has it Cadillac is working on an even hotter version of the ATS-V, possibly called ATS-V+. And the latest intel from Motor Trend suggests this new model might have a great, big V8 under the hood. The V8 in question is the high-revving, naturally aspirated 7.0-liter LS7 from the Camaro Z/28. The hand-built engine makes 505 horsepower and 481 pound-feet of torque in the Z/28 – a nice increase over the 464 hp and 445 lb-ft in the standard ATS-V, which uses a twin-turbocharged 3.6-liter V6. Motor Trend says the ATS-V+ will come to market with an eight-speed automatic transmission, as well as the seven-speed manual 'box from the Corvette. A dual-clutch transmission will come to market later. Of course, we'll believe it when we see it. But an LS7-powered ATS-V sure sounds like a great package to us. Here's hoping.

GM says safety is a reason it's dropping Apple CarPlay, Android Auto

Update: GM sent us a statement as a follow-up to its original comments seen in this post: "We wanted to reach out to clarify that comments about GM's position on phone projection were misrepresented in previous articles and to reinforce our valued partnerships with Apple and Google and each company’s commitment to driver safety. GM's embedded infotainment strategy is driven by the benefits of having a system that allows for greater integration with the larger GM ecosystem and vehicles." The original story can be read in its entirety below.   General Motors announced its intention to remove Apple CarPlay and Android Auto functionality from its upcoming EVs earlier this year, and internet comments sections haven't been kind since. As the first of many EVs to follow – the 2024 Chevrolet Blazer EV – hits the market, GM is expanding on its initial explanations for dropping the tech. Motor Trend spoke with Tim Babbit, GMÂ’s head of product for infotainment, to learn more. Attributed to Babbit, from the story: “They have stability issues that manifest themselves as bad connections, poor rendering, slow responses, and dropped connections. And when CarPlay and Android Auto have issues, drivers pick up their phones again, taking their eyes off the road and totally defeating the purpose of these phone-mirroring programs. Solving those issues can sometimes be beyond the control of the automaker.” Babbit suggests that a world without Apple CarPlay or Android Auto will be a safer one, as folks wonÂ’t be looking to control their infotainment systems via their phones. However, Babbit also tells MT that this theory hasnÂ’t been tested in either the lab or the real world yet. Instead of using a navigation or music-playing app powered through your phone, upcoming GM EVs will use a Google-based infotainment system called “Ultifi” that runs a ton of integrated Google apps. Google Maps will be the native navigation app in the system; youÂ’ll be able to log in to Spotify or other apps to load your music up, and so on. The idea here is that youÂ’ll have all the same apps that were on your phone available but integrated within the infotainment system instead, and you'll be able to use voice controls to control every last bit of it with no need to reach for a phone. That sounds amenable in theory, but how consumers react to the removal of a feature that they know and love now is a risky gamble.
