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.

GM Design shows what could have been and what might be

We periodically like to check in with GM Design's Instagram account to see what they're cooking up. Even better is when we catch a glimpse of an alternate history of what legendary designers from The General's past were thinking, though those ideas may not have made it into production. This week, for example, the account posted some illustrations from George Camp, whose career at GM spanned nearly four decades, from 1963 to 2001. One of the renderings is of what appears to be a 1971-72 Pontiac GTO Judge, but with two headlights instead of the production unit's quad beams. The rear departs from the canonical version most dramatically, with a massive integrated wing. Other bits that didn't make the production cut include large side vents, a gill-like side marker and rectangular intakes below the headlights that wouldn't be out of place on a modern design today. Amazingly, from what we can make out of the date, it appears that the drawing was done sometime in 1965, which makes it quite prescient.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) There's also a very aerodynamic interpretation of a Corvette ZR-1. To our eyes it splits the difference between the 1986 Corvette Indy concept and a fourth-generation F-body Pontiac Firebird, so perhaps parts of Camp's work on this sketch did make it into physical form. There's also a radical sports car concept from May 1970 that resembles the Mazda RX-500 concept from the same year, a Syd Mead-looking Cadillac coupe, and an Oldsmobile with a cool take on the company's trademark waterfall grille and elements of the Colonnade Cutlass at the rear. Other recent posts include a FJ Cruiser-like off-road EV, a sleek coupe with the Chevy corporate grille, and a rendering of a Silverado-esque pickup that looks far better than the current production version.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) It's pretty easy to lose hours in the account, but it's always fascinating to see GM's visions of what could have been and what might be.

Recharge Wrap-up: Renault Zoe recall, Proterra buses log 2M miles

Renault is recalling 10,649 examples of its Zoe electric car for potential brake hose failure. Cars built at the company's Flins factory between the Zoe's 2012 introduction and October 6, 2014 - a quarter of all Zoes ever built - are subject to the recall, though no accidents have been reported from rupturing brake lines. Recalled vehicles will have the brake hose positions inspected and, if need be, fixed. Read more from Reuters. Proposed legislation in Massachusetts would make the state even more EV friendly. While the state already encourages EV adoption with a $2,500 rebate incentive, the new bill would give battery electric vehicle drivers HOV lane access. Additionally it would set up a standard building code for EV chargers, and allow EV-only parking spaces. "With decreased gas prices, a 10 percent increase in vehicle miles traveled over the last 20 years, and a carpool rate below the national average, we must address personal vehicle use directly as part of our transportation emissions reduction strategy," says Rep. Frank Smizik. Read more from Teslarati. The New York Daily News has named the 2016 Chevrolet Volt as its "Green Machine of the Year." Seamless operation, peppiness, and a nice suite of equipment make it a top choice for the publication. "The 2016 Chevrolet Volt is all new, inside and out, and takes the plug-in hybrid segment to another level, thanks to its increased EV range, updated cabin, and more efficient gas-powered engine," writes Daily News Autos writer (and all-around good guy) Nick Kurczewski. Honorable mentions go to the Tesla Model S, BMW i3, Toyota Prius, and the hydrogen-powered Toyota Mirai. Read more from the Daily News, or at Clean Technica. Proterra electric buses have accumulated 2 million miles of revenue service. That equals 3,800 tons of carbon emissions that have been prevented and 420,000 gallons of fuel unburned. Proterra says it has 63 buses in service in 15 cities, and that it is ramping up production to meet growing demand. "This latest milestone exemplifies the economic, environmental and civic value of electric mass transit," says Proterra CEO Ryan Popple, "and demonstrates to the transit agencies that diesel - often viewed as a necessary evil - is no longer necessary."
