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.

NHTSA investigates 1.7 million GM SUVs for windshield wiper failures

WASHINGTON - The U.S. National Highway Traffic Safety Administration (NHTSA) said on Tuesday it is investigating whether General Motors should recall an additional 1.7 million sport utility vehicles due to an issue with windshield wiper failures. GM in August 2016 recalled 367,800 2013 GMC Terrain and Chevrolet Equinox SUVs in the United States to address the problem. But after receiving 249 complaints about similar problems, the federal agency said it is probing whether the recall should be expanded to include an additional 1.7 million vehicles from the 2010-2016 model years. The automaker said it is cooperating with the NHTSA review. GM said it recalled the 2013 GMC Terrain and Chevrolet Equinox SUVs "because warranty data showed a higher-than-expected failure rate," adding it has continued to monitor field data on other model years of those vehicles. GM noted that no crashes or injuries related to the issue have been reported. The Detroit-based automaker said the recalls were prompted after a GM Canada brand quality manager reported a potential safety issue relating to reports of windshield wiper failures in Canada through GM's "Speak Up For Safety," program in late 2015. The data showed significantly higher field incidents in parts of Canada, which prompted a June 2016 recall there. Over the next two months, a higher number of U.S. reports prompted a U.S. recall, the company added. In the 2016 recall, GM said the front-wiper module would be replaced with a module that has a water deflector and, if needed, dealers would fill the water management hole and drill a new small hole in a different location.(Reporting by David Shepardson, editing by G Crosse)Related Video: Government/Legal Recalls Chevrolet GM GMC SUV

Opel Ampera-e brings a Bolt of EV driving to Europe

The Chevrolet Bolt will take a trip across the Atlantic in 2017 to become Europe's Opel Ampera-e. General Motors won't release any specs for the foreign version yet, but these photos suggest very minor styling tweaks to the upper level of the grille and to the hatchback to add the appropriate brand emblems. We would expect the same electric motor with 200 horsepower and 266 pound-feet of torque and 60-kWh battery as the US model, too. However, the 200-mile range number might change, but only because of the differences in European testing. GM CEO Mary Barra announced the Ampera-e at the CAR Symposium in Bochum, Germany. "GM and Opel have always been convinced that electric cars will play a defining role in future mobility. The game-changing technology of the Ampera-e is a significant step toward realizing that vision," she said. The Ampera-e is also proof that General Motors loves confusing naming for its green models. If the Volt and Bolt aren't perplexing enough, the Ampera-e is just one letter off from the Ampera – the previous-gen Volt in Europe. GM no longer sells the range-extended vehicle there, so at least both names can't be in showrooms simultaneously. However, the similar monikers still might confuse some customers who think the new EV hatchback is closely related to the old sedan.

Opel Group will launch a revolutionary new battery electric car next year, as the company continues the biggest, most far-reaching model offensive in its history with 29 new models between 2016 and 2020. The new five-door, five seat will be called "Ampera-e". It will not only have a longer range on a full charge than most electric cars, it will also be affordably priced. Building on the electrification expertise established with the original Ampera, which set the benchmark for modern electric cars in 2011, the new Ampera-e combines innovative electric-mobility with state-of-the-art connectivity and exciting driving dynamics. Announcing the Ampera-e today at the CAR Symposium in Bochum, Germany, GM Chairman & CEO Mary Barra said: "GM and Opel have always been convinced that electric cars will play a defining role in future mobility.
