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 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.

GM finds steering flaw, decides it doesn't warrant a recall

Guess what? General Motors is back in the spotlight for not recalling something. This time, though, not only does the company have an argument against a recall campaign, but its position is supported by the National Highway Traffic Safety Administration. According to The New York Times, over 50 owners of GM vehicles have reported instances of stuck or seized steering after driving long distances without moving the wheel. One owner complained to NHTSA that the "locked" steering of their 2013 Buick Verano caused a collision with a concrete barrier in a construction zone. Along with the 2013 to 2014 model year Verano sedans, Chevrolet Cruze and Malibu sedans are also affected. Considering the popularity of those models, GM needs to have a reason for not issuing a recall, right? "Based on a very low rate of occurrence – ranging from less than one half to less than two incidents per thousand vehicles – and the fact that the condition is remedied when the wheel is turned, GM determined this was not a safety issue," spokesman Alan Adler told The Times. The company has, however, issued a technical service bulletin for owners that complain of the problem. The fix is nothing more than a software update that is covered for 10 years or 150,000 miles from new. NHTSA cited GM's actions, along with descriptions of the problems from customers, in its decision not to issue a recall, with spokeswoman Catherine Howden saying, "the symptoms described would be a brief, perceptible change in steering feel that has little to no effect on the driver's ability to safely steer the vehicle." "When terms like 'notchy,' 'stick,' 'slip' or 'feel' are used, it does not indicate a meaningful increase in steering effort," Howden told The Times via email. What do you think? Is GM in the wrong here? Should there be a recall, or is the issue so limited as to not warrant one? Have your say in Comments.
