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.

Next-gen Chevy Volt will get 1.5-liter, four-cylinder engine

As General Motors gets ready to unveil the new Chevy Volt at the Detroit Auto Show in January, it's starting to reveal a few more details about the updated plug-in hybrid. Today should be fruitful on that front, thanks to an event GM is hosting today that focuses on the new Volt, and we've just had the first bit of new: a bigger engine is coming. Since the beginning, the Volt has used a 1.4-liter, four-cylinder engine as a range extender when the battery runs dry. The second-generation model will instead get a slightly larger 1.5-liter, four-cylinder engine that will be built in Flint, MI. That's a step up from the various engines that have been a part of the 2016 Volt's rumored mills, everything from a 1.0-liter or 1.2-liter three-cylinder to a 2.0-liter turbo. The confirmation about the new 1.5-liter powerplant was found in Automotive News, where we also heard again that GM is going to start building the new Volt's electric drive unit in Detroit, moving production up from Mexico. We will have more information on the 2016 Chevy Volt later today.

Chevrolet SS previewed by Holden VF Commodore SS V show car

It won't be long before we see the official, production-ready Chevrolet SS sedan (hint: it will be revealed this weekend). And to tide us over until all of the official details are released about the US-spec version, we have this: the Holden VF Commodore SS V show car, a performance-oriented brother to the Calais V that debuted earlier in the week.
What we really want to know about the SS V is what lies underhood, but General Motors' Australian arm is keeping that under wraps until the Chevy model breaks cover this weekend. Nevertheless, it's obvious that the SS V will be a serious performer, with all sorts of aggressive cues driving that home on the car's exterior. Take a look at those 20-inch billet aluminum wheels that hide big Brembo brake calipers up front, the sculpted hood and front fascia, the wide air intakes with LED running lights and the quad exhaust pipes out back. It's like the Pontiac G8 GXP never even left us.
Inside, there's a sporty-looking interior with aluminum accents that mix in with black leather and suede surfaces, all tied together in the middle with an eight-inch MyLink touchscreen infotainment system. It looks great, and again, while we don't know anything regarding powertrain details, it makes us oh-so happy to see a manual shifter smack dab in the middle of the center console.
