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 tells owners not to use SUV wipers due to fire risk

General Motors is recalling 31,685 examples of the 2016 Buick Enclave, Chevrolet Traverse, and GMC Acadia because a short circuit in the windshield wiper motor can potentially lead to a fire. Due to the danger, the company is asking owners not to use the wipers until the problem is fixed, according to The Detroit Free Press citing the Associated Press. A manufacturing defect in the wiper motor cover means that the electrical terminals can come into contact and cause a short. The part could "melt, smoke, or catch fire," according to a statement from GM. The company will get them fixed immediately, and dealers will replace the cover. If there's bad weather at the time the owner specifies to get the recall work completed, the automaker will come pick up the crossovers. Depending on parts availability, the automaker will supply a rental car for customers, as well. The issue was discovered at the factory. According to the company's statement, only 6,405 actually made it to customers, and they were notified immediately by overnight letter. The rest were in dealer stock. The affected crossovers carry build dates between August 18, 2015 and September 24, 2015. Of those, there are 29,295 in the US and 1,073 in Canada. GM Statement: General Motors has told the National Highway Traffic Safety Administration that it will recall approximately 29,295 2016 model year Chevrolet Traverse, Buick Enclave and GMC Acadia SUVs in the U.S. because the front windshield wiper motor may overheat when in use because of a manufacturing defect. In some cases, the front windshield wiper motor cover may melt, smoke or catch fire. The approximately 6,405 customers who have taken delivery of these vehicles were notified by overnight letter and are urged to contact a GM dealer as soon as possible to arrange a service appointment. These customers should not use the front windshield wipers until they have been repaired. If weather conditions prevent driving the vehicle without using the windshield wipers, GM will arrange to pick up the vehicle for servicing. If repair parts are unavailable, GM will provide a rental car at no cost until parts become available. The total population, including Canada, Mexico and exports, is approximately 31,685. About 25,280 of these vehicles are in dealer stock and will not be sold until repairs are made.

GM seeks national mandate for zero-emissions cars

DETROIT — General Motors says it will ask the federal government for one national gas mileage standard, including a requirement that a percentage of auto companies' sales be zero-emissions vehicles. Mark Reuss, GM's executive vice president of product development, said the company will propose that a certain percentage of nationwide sales be made up of vehicles that run on electricity or hydrogen fuel cells. GM says a nationwide program modeled on such a requirement in California could result in 7 million electric vehicles, or EVs, on U.S. roads by 2030. California wants 15.4 percent of vehicle sales by 2025 to be EVs or other zero emission vehicles. Nine other states, including Maryland, Massachusetts, New Jersey and New York, have adopted those requirements. In January, California Governor Jerry Brown set a target of 5 million zero-emission vehicles in California by 2030. The Trump administration criticizes California's ZEV mandate, saying it requires automakers to spend tens of billions of dollars developing vehicles that most consumers do not want, only to sell them at a loss. Reuss told reporters that governments and industries in Asia and Europe "are working together to enact policies now to hasten the shift to an all-electric future. It's very simple: America has the opportunity to lead in the technologies of the future." A national mandate also would create jobs and reduce fuel consumption, CO2 emissions and "make EVs more affordable," Reuss added. GM, the nation's largest automaker, will spell out the request Friday in written comments on a Trump administration proposal to roll back Obama-era fuel economy and emissions standards, freezing them at 2020 levels instead of gradually making them tougher. Under a regulation finalized by the Environmental Protection Agency at the end of the Obama administration, the fleet of new automobiles would have to get 36 miles per gallon by 2025, 10 mpg higher than the current requirement. But the Trump administration's preferred plan is to freeze the standards starting in 2021. Administration officials say waiving the tougher fuel efficiency requirements would make vehicles more affordable, which would get safer cars into consumer hands more quickly. GM on Thursday said it doesn't support the freeze, but wants flexibility to deal with consumers' shift from cars to less-efficient SUVs and trucks.
