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.

Motor Trend wheels the 2015 Corvette Z06

The new Chevrolet Corvette Z06 is capable of some absolutely wild metrics. Want proof? Carlos Lago from Motor Trend is here to break it all down. 60 miles per hour? 3.2 seconds. 60 to 0? 91 feet. Lateral acceleration? A staggering 1.16g, a figure that is the highest MT has ever recorded for a vehicle that isn't a race car. It's an utterly astonishing piece of work, this Z06, and just when you think it can't possibly get any more impressive, Randy Pobst hustles an auto-equipped Z06 around Road Atlanta in just 1:30. Aside from the eight-speed auto, Pobst's Z06 had the most aggressive aerodynamic package, the so-called Stage III. Take a look at the 650-horsepower Z06 in Motor Trend's latest video.

First 2014 Chevy Corvette Stingray spotted crashed in the wild

This restyled blue 2014 Chevrolet Corvette Stingray is wearing manufacturer plates, and it appears to be the same one seen around the internet in various pictures lately. This crash is likely not part of the Chevrolet testing regimen, however. Digital Corvettes forum member gpetry posted the shot with a note: "got this picture e-mailed from a friend in Arizona last week..." No circumstances are given, other than the incident occurred in the thick of a set of curvy roads, and the coupe ping-ponged off a guardrail and into the rock wall. Hopefully everyone involved in the incident walked away.
It may not be a pretty thing to see, a crashed sports car that's not even available for sale yet, but rest easy. Many pre-production cars are used for development and then unceremoniously crushed and scrapped, anyway. If that's the case here, that makes this wrecked 'Vette less of a tragedy and more of a case of exceptional efficiency.
