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.

What car should James Robertson buy to drive his famous 21-mile commute?

The Internet has been abuzz this week with the story of Detroit resident James Robertson, the 56-year-old factory worker who has walked some 21 miles to work for the last 10 years. The Detroit Free Press brought Robertson's story to the fore, helping an online fundraising campaign to generate more than $275,000 (as of this writing). The original goal was just $5,000, or about enough to replace the used Honda that died on Robertson back in 2005, and left him walking. So, newly flush with funds, what's the perfect car for Robertson to buy? Let's look at the specifics of his situation, and try to pick out the best options. Here's what we know: Robertson's commute is (famously) 21 miles; he lives in downtown Detroit (for now) and seems pretty humble, so something very flashy is probably out; former Honda aside, his ties to the city (and statements about being a Ford fan) seem to indicate a Detroit Three company product is best; he's a single guy with a girlfriend; he's got to deal with Michigan weather, and the sometimes fickle snow removal processes in The D. Here are some choices: Ford F-150 Robertson is on record as being a Taurus fan, and after a decade of walking I've no doubt that the big sedan would offer a cozy respite. Still, as a car guy and a student of the industry, I'd have a hard time recommending a sedan so clearly in need of replacement. Especially when The Blue Oval has such great stuff within the rest of its roster. The 2015 F-150 seems almost perfect for Robertson. Opting for either of the new EcoBoost V6 engines should help keep fuel bills in reasonable check, while healthy ride height and four-wheel drive will get him to work on time even during the snowiest of snow days. Better still, with a fat options sheet and car-like ride quality, Robertson can have just about every amenity he might want, in a package that won't disrespect his blue-collar roots. Chevrolet Colorado You guys saw this one coming, right? The smaller footprint of the midsize Chevy pickup, relative to some of the other options here, should be an advantage for urban parking and driving. And again, 4x4 is an option for the nasty weather, the running costs should stay pretty low and there aren't many tech/luxury features that can't be had in-cabin. I'd go ahead and splash out on the Crew Cab bodystyle, too, just in case Robertson feels like starting a carpool.

GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.
