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.

New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.

GM admits Cadillac ELR no real competition for Tesla Model S

Last year, then-CEO of General Motors, Dan Akerson, made it clear that the company lookouts at the Ren Cen had California automaker Tesla in their sights. "If you want to compete head-to-head with Tesla, and we ultimately will, you want to do it with a Cadillac," he said. So, given the fact that the Cadillac ELR has a plug and sells for roughly the same price at the Tesla Model S ($75,000 vs $69,900, before incentives) and that Cadillac doesn't have any other electric vehicle on the horizon, you'd be forgiven if you thought that the way that Akerson wanted to challenge Tesla's EV success was with the ELR. Well, you'd apparently be wrong. "The ELR is a different car, it's a different price point. It's way-different technology." - GM's Mark Reuss Speaking yesterday in Detroit, GM's head of global product development, Mark Reuss, admitted that the ELR is not the Tesla competitor that Akerson promised. "People like to say the ELR is [competition for the Model S], but it's really not. It's a different car, it's a different price point. It's way-different technology." So, if we follow that logic to conclusion with Akerson's quote from last year, then the only way that Cadillac can eventually compete with Tesla is with a pure electric car, and that seems an outside chance, at best, for the foreseeable future. Through the end of July, Cadillac has sold 578 ELRs since it went on sale earlier this year. Tesla doesn't break out monthly US sales, but has sold 15,114 Model S EVs around the world in the first six months of 2014. For his part, Tesla CEO Elon Musk has already said that GM is headed down the wrong path with plug-in hybrids like the ELR or the Chevy Volt. Speaking about the Volt last year, Musk said, Chevy "sort of created something that's a bit of amphibian," which resulted in a car that's, "Okay but not great."
