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.

Chevrolet planning low-cost Corvette under Stingray?

If you're burnt out on musings about the Chevrolet Corvette, you'll want to go ahead and skip this post. Motor Trend reports General Motors is hard at work on a low-cost version of the seventh-generation sports car for 2015. Rumored to be called the Corvette Coupe, the car will forgo the Stingray and skip the 450-horsepower 6.2-liter V8 engine in favor of a 5.3-liter V8 with under 400 ponies. If you're keeping track, that's a shade of the same engine found behind the headlights of the 2014 Chevrolet Silverado and GMC Sierra.
The report also suggests the Coupe will receive a number of aesthetic tweaks to separate it from the Stingray, including different front and rear fascias as well as new front fenders and a rear diffuser. Motor Trend says the point of all this is to cut the car's price tag, which means we may see a Corvette on showroom floors for less than $50,000 if this car comes to fruition.

GM will recall more than 3.3 million vehicles in China for suspension defect

BEIJING (Reuters) - General Motors' joint venture in China, Shanghai GM, will recall more than 3.3 million Buick, Chevrolet and Cadillac vehicles stating Oct. 20 because of a defect with the suspension system, China's market regulator said on Saturday.
