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.

Chevy recalls 73k Cobalts for side airbag non-deployment

Chevrolet is recalling 73,424 examples of the 2010 Cobalt in the US and Canada because the driver's side curtain airbag might not deploy in a crash. These vehicles carry build dates between January 4 and June 23, 2010, and, specifically, 59,474 of them are in the US. "GM is aware of one crash with one injury that may be related to this condition," the company said in a statement. The problem occurs because of improper routing of the side-impact sensor wiring harness in the driver's door, and there can be a short circuit causing the curtain airbag not to deploy. The campaign to fix the issue will begin on August 26. Dealers will inspect the vehicles and will repair the issue on any affected examples. Related Video: GM Statement: General Motors is recalling 59,474 2010 Chevrolet Cobalt sedans in the U.S. because some of them may have been built with improper side impact sensor wire routing in the left front door. Dealers will inspect all suspect vehicles and any found with the condition will be repaired free of charge to the customer. GM is aware of one crash with one injury that may be related to this condition. Including vehicles sold in Canada, the total recall population is 73,424. RECALL Subject : Improperly Routed Side Impact Wire Harness Report Receipt Date: AUG 10, 2015 NHTSA Campaign Number: 15V500000 Component(s): AIR BAGS Potential Number of Units Affected: 59,474 All Products Associated with this Recall Vehicle Make Model Model Year(s) CHEVROLET COBALT 2010 Details Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2010 Chevrolet Cobalt vehicles manufactured January 4, 2010, to June 23, 2010. The affected vehicles may be equipped with an improperly routed Side-Impact Sensor (SIS) wiring harness in the driver side front door. The misrouted wiring harness could cause an electrical short that disables the driver side curtain air bag. CONSEQUENCE: A disabled driver side roof-rail air bag will not deploy in the event of a crash necessitating deployment of that air bag, increasing the risk of injury to the driver. REMEDY: GM will notify owners, and dealers will inspect the sensor's wiring in the driver's door and make repairs as necessary, free of charge. The recall is expected to begin August 26, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 15075.

2016 Chevy Camaro to drop 200 pounds

The sixth-generation Chevrolet Camaro makes its grand debut on May 16 at a big celebration on Detroit's Belle Isle. Until then, Chevy's strategy seems to be showing off the pony car's new components piece by piece. With the exhaust headers and front end already on display, the Bowtie is now giving a glimpse at some of the upcoming model's aluminum components. The Camaro is going on a diet for its latest generation, and Chevy claims that the switch to the Alpha platform and other new components shed over 200 pounds compared to the current model. That will put the pony car at around 3,500 pounds. The lower weight will contributes to better fuel economy, quicker acceleration and more direct handling, according to the automaker. Among the changes are aluminum front and rear suspension assemblies (pictured above) that weigh 21 percent less than the current units. Also, Chevy promises in its announcement "links on some models feature an intricate, structurally optimized design made with a rigid composite material that's even lighter than aluminum." In addition to these improved parts, the Camaro uses the lightweight metal for the beam that supports the instrument panel to save 9.7 pounds more. The only two pieces reportedly carrying over to the latest design are Chevy's bowtie and SS badges, and at least one engine in the range is known to be a version of the 6.2-liter LT1 V8. With over a month until the next Camaro's debut, we might get a glimpse of even more of the car's new parts in the coming weeks.

To meet all three objectives, the team focused on a singular mission: reduce mass. By obsessively searching for opportunities to save ounces, the team pared more than 200 pounds off the Camaro compared with the fifth-generation model. As a result, the Camaro does more with less, according to Al Oppenheiser, Camaro chief engineer: "We kept the cornering confidence and control that make the Gen 5 Camaro 1LE so fun to drive, and added a greater sense of agility," he said. "The new Camaro brakes harder, flicks into corners more quickly, and drives out of the corner faster.
