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 recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

Chevy Sail 3 lands in China

Shanghai General Motors took 32 cars to this year's Guangzhou Motor Show, with its Chevrolet Sail 3 leading the way. After putting almost 1.4 million of them into Chinese hands, the third generation of the Bowtie's entry-level sedan wants to "take the nameplate and the segment to a new level." Its new architecture sporting a 1.4-inch longer wheelbase supports a growth spurt of two inches in length and 1.8 inches in width. The exterior also gets "eagle eye-shaped" headlights and "dual-c-element taillights." Under the hood will be either a 1.5-liter DVVT or a 1.3-liter VVT, each of them more powerful and more frugal than previous offerings. Both can be paired with a manual or an automatic transmission, and qualify for listing in China's National Energy-Saving and Eco-Friendly Vehicle Catalogue, as well as a 3,000 renminbi rebate ($490 US). You can read more about it in the press release below, and get more info on the Chevrolet Camaro RS Limited Edition, Corvette Stingray Coupe, Buick Regal GS and Excelle XT also introduced at the show.
