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.

2016 Chevy Silverado puts on a better face

When Chevrolet introduced the redesigned Silverado pickup for 2014, you, our loyal readers, gave the new truck's front-end a lukewarm response. Aside from saying it was ugly, one commenter came to the far more damning conclusion that this brand-new vehicle already looked dated. For 2016, Chevy has attempted to address opinions like that, issuing a comprehensive facelift to its bread-and-butter pickup. Designers cut way back on the chrome for 2016, fitting a body-color strip across the middle of the grille and going to a single-headlight design. Combined with twin LED running lamps, the new look is much more modern while still harkening back to the retro-ish look introduced a few years back. The new truck also gets a much more muscular and aggressive hood, while the front bumper is significantly more modern, and features vertical housings for what look like LED foglights. The bad news, here, is that there's only one picture, shown above. We have no idea what changes Chevy has made to the rear of the pickup, nor do we know what other versions of the truck beyond the Z71 seen here may be available. The Bowtie brand did, however, confirm that we'd see a wider application of the eight-speed automatic transmission, as well as a new version of the MyLink infotainment system, which will play nice with both Apple CarPlay and Android Auto. Look for much more on the freshened Silverado when it makes its official debut this fall. Until then, check out the press release and hop into Comments. We'd love to hear what you think about this facelift. 2016 Silverado: The New Face of Strong - Bolder, more sculpted look reflects Silverado strength, dependability - Available support for Android Auto and Apple CarPlay - Expanded use of 8-speed transmissions; additional safety technologies DETROIT – Chevy Trucks are on a roll, with Chevrolet pickup sales up 32 percent so far this year. Chevrolet intends to strengthen this momentum with significant updates for the 2016 Silverado 1500 full-size pickup. "The redesigned 2016 Silverado will build on Chevy Trucks' legacy of dependability. It will feature a more muscular appearance and offer new customer-focused technologies," said Sandor Piszar, marketing director for Chevy Trucks.

Camaro chief: 'rock-star' 4-cylinder set for Mustang fight

It was inevitable, the 2016 Chevy Camaro had to have a four-cylinder engine. The archrival Ford Mustang packs a spunky 2.3-liter EcoBoost four-banger, and everyone from BMW to Subaru uses four-cylinders to great effect to power their sports cars. Now it's Chevy's turn. Again. The Camaro ran the infamous Iron Duke four-cylinder with 88 to 92 horsepower in the 1980s. It was a fuel-economy play at a time when performance was not a priority. After the 1970s muscle-car era, output even for the V8s didn't top 200 hp again until the mid-'80s. Thankfully for enthusiasts, things have changed dramatically in the last 30 years. The gen six Camaro will offer a 2.0-liter inline four-cylinder with 275 horsepower. It's the standard engine, slotting below the 335-hp V6 and the 455-hp V8. But don't mistake the new I4 for an Iron Duke encore. Camaro chief engineer Al Oppenheiser called it a "rock star" and said cars equipped with it feel lighter than V6 models. The four-cylinder (295 pound-feet at 3,000-4,500 rpm) also summons more torque in quicker fashion than the V6 (284 lb-ft at 5,300 rpm). Chevy expects the Camaro to hit 60 miles per hour in "well under six seconds," according to press materials. The Mustang EcoBoost (310 hp, 320 lb-ft) clocks times in the low to mid five-second range. "We're not doing it just so we have one," Oppenheiser said. "We're not doing it because like in gen three you're forced to do it because of fuel economy. We're doing it because it belongs in the car. It has a distinct character." Speaking with Autoblog recently at the Detroit Grand Prix racecourse on Belle Isle, Oppenheiser said he expects the I4 to attract a younger crowd to the Camaro and will put up stiff competition against the V6 for sales. "I've read blogs where younger folks won't buy a Camaro because it doesn't have a 2.0-liter turbo or a turbocharged four-cylinder," he said. "So we're going to excite them." While we talked a lot about four-cylinder engines, Oppenheiser also elaborated on the V6 (It's pretty damn good, too. We drove it.) and the new Alpha platform that the Camaro borrowed from Cadillac. Here's the rest of our edited conversation. Autoblog: Talk a little bit about the four-cylinder – the first turbo four-cylinder ever for Camaro. Do you have any idea what the take rate's going to be? Al Oppenheiser: I think it's going to surprise a lot of people. It's actually a fun car to drive. It's got a really good balance of turbo noise and exhaust note.
