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.

Cadillac recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.

Cadillac ELR regen on demand brakes win 2014 Green Car Technology award

Just like the Oscars, Green Car Journal decided a few years ago to up the number of nominees for its annual award. For the annual "Green Car of the Year" award, given out at the Los Angeles Auto Show each year, there are five finalists. For the "Green Car Technology" award, there are a fantastic ten. At the 2014 Washington Auto Show today, the Cadillac ELR and its regen on demand brakes managed to beat out the nine other finalists to claim the second annual "Green Car Technology" award. What is the purpose of the "Green Car Technology" award? Green Car Journal says it wants to reward "technologies that enable significantly improved environmental performance in vehicles today," which is why only fuel-saving technologies that were "in use on American highways during the award year" can be considered. The Caddy's brakes beat out the Acura Sport Hybrid SH-AWD powertrain, the Audi 3.0-liter turbodiesel engine, the BMW carbon-fiber passenger shell from the i3, the 1.0-liter EcoBoost engine used by Ford, the plug-in hybrid powertrain in the Honda Accord, Hyundai's hydrogen fuel cell technology, the regenerative brakes in the Mazda i-ELOOP, the plug-in hybrid powertrain used in some Porsche models and, finally, the Ram 3.0-Liter EcoDiesel engine. Last year, Green Car Journal gave Mazda's Skyactiv technology the inaugural Green Car Technology award. Cadillac ELR Regen On Demand Wins 2014 Green Car Technology Award Green Car Journal Lauds Cadillac's Electric Car Tech at Washington Auto Show WASHINGTON, Jan. 22, 2014 /PRNewswire/ -- Cadillac's innovative Regen on Demand technology has taken top honors as the winner of Green Car Journal's 2014 Green Car Technology Award™. The prestigious award was presented at a Green Car Journal press conference during the Washington Auto Show's second Policy Day. "Cadillac has cleverly evolved a common electric-drive efficiency system into an intriguing feature that adds a new dimension to the driving experience," said Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com. "Ever-increasing efficiency is crucial to our driving future, yet efficiency itself is not an attraction for a great many car buyers.
