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.

2016 Chevy Camaro Convertible gets cleaner looks, improved refinement [UPDATE]

UPDATE: We have live photos from the reveal. Scroll to the bottom of the story and check them out in the Related Gallery. Back in May, Chevrolet introduced a redesigned Camaro. Now, and not at all surprisingly, the Bowtie brand is showing off the latest Camaro convertible, based on the coupe that debuted on Belle Isle in Detroit. From the beltline down, this is the same car that was so well-received last month. But above the waist, there's an all-new, fully automatic canvas roof that can be raised and lowered at speeds up to 30 miles per hour. On top of that, owners will be able to drop the roof remotely by simply pressing a button on the key. Chevy does not, however, say if this new convertible roof is lighter than last year's top. The biggest change for the Camaro convertible, though, is something we've long yearned for – a proper hard tonneau cover that deploys over the folded roof. The current muscle car's roof fabric has the unpleasant tendency to flap in the breeze. The new droptop shouldn't have that problem, and will likely boast an even cleaner top-down profile to boot. Like the hardtop, though, the Camaro convertible does benefit from the same lightweight structure, that helps trim "at least" 200 pounds of body fat. It should also make use of the same powertrain lineup, with a turbocharged four-cylinder, a 3.6-liter V6, and a 6.2-liter V8 with six-speed manuals or eight-speed automatic transmissions spanning the lineup. "From the beginning, the Camaro's architecture was developed to incorporate a convertible with uncompromised driving dynamics," Camaro chief engineer Al Oppenheiser said in the attached release. "Customers will appreciate what they don't feel: quivers, cowl shake or an under-damped chassis typically found in a four-seat convertible." Increased refinement, a cleaner look, better driving dynamics and a more usable convertible roof? We're looking forward to you 2016 Camaro convertible. Chevy claims the new car arrives in "early 2016," which means we should plan on seeing this droptop at the typically cold and snowy Detroit Auto Show. Until then, check out the full press release from Chevrolet.
