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.

Stop-start standard in four-cylinder 2015 Chevrolet Impala

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined. The 3.6-liter V-6 Impala will not feature stop-start. The 2015 Impala comes equipped with Chevrolet's 2.5-liter Ecotec four-cylinder engine, which will also offer 22 mpg in the city, and 31 on the highway. The 3.6-liter V-6 Impala will not feature stop-start and the mild-hybrid eAssist model from the 2014 MY, which got 29/25/35 combined/city/highway mpg, has been discontinued. Chevrolet spokesman Chad Lyons told Green Car Reports that not even one percent of the 2014 Impalas purchased were the Eco model. So Chevy is trying something different. With a seamless driving experience in mind, the new Impala's stop-start tech features software that governs under what conditions the feature will activate. The engine won't shut off if the car has not reached a speed of six miles per hour, so the start-stop won't be cycling during traffic jams. It can also fire the starter even if the engine has not come to a full stop, which quickens reaction time, particularly in instances of what Chevrolet calls "change-of-mind events." The stop-start function uses information about cabin temperature and humidity as well as battery charge to help determine whether or not to shut off the engine. The 2015 Impala has been engineered to reduce NVH, which will also help create a smoother stop-start experience for occupants, Chevy says. Motor mounts have been updated, and a burlier starter motor will help restart the engine after a stop. The Impala follows the 2014 Malibu as Chevrolet's second vehicle to feature stop-start tech. The four-cylinder model currently makes up over 30 percent of Impala sales. The 2015 Impala will be available beginning this summer, with a base MSRP of $27,735 (including destination charges). And while one MPG isn't a huge difference, neither is the price increase of just $50 for a bit of eco-minded innovation. Read on for more details in the press release below. Chevrolet Makes Stop/Start Standard in 2015 Impala Technology improves city fuel economy by 5 percent 2014-05-22 DETROIT – Stop/start technology will be standard on the 2015 Impala base 2.5-liter ECOTEC® engine, an addition that improves the vehicle's city fuel economy by nearly 5 percent, or one mile per gallon.

Weekly Recap: Chevy and Alfa plot comeback strategies

Chevrolet and Alfa Romeo were two of the 20th Century's most iconic automotive brands. Chevy embodied America's post-war power and confidence. Alfa was the definition of the stylish Italian sports car. They reached halcyon heights in the 1950s and '60s, before declining precipitously amid new competition, changing consumer tastes, and uneven corporate management. Both say 2015 is the start of something better, and this week Chevy and Alfa laid out ambitious plans and showcased new cars that they hope will make them more relevant this year, and in the coming years. Each brand sits at its own crossroads, and their paths forward are as different as the Chevy Cruze and the Alfa Romeo Giulia. Chevy is still a sales beast, as evidenced by its volume of 4.8 million vehicles sold around the world last year. Chevy executives are fond of saying one of their cars is sold every seven seconds, which illustrates the strength and reach of a car brand that is the fourth largest in the world. "Make no mistake about it, we are a brand for the people," said General Motors North America president Alan Batey. But he wants consumers to want to buy a Chevy for its design and technology, not simply because it's affordable. That starts with all Chevys now featuring a distinctive a family look, with sporty cues from the Corvette or strong lines that riff on the Silverado pickup. "We want people to fall in lust with our cars," said Mike Pevovar, executive design director for Chevy passenger cars. "That initial emotional attraction has to be right on the exterior, and that's where form comes into play." Chevy is also loading up its cars, like the freshly unveiled 2016 Chevy Cruze, with technology to appeal to a younger crowd that prizes connectivity. The Cruze will offer Apple CarPlay and Android Auto with its MyLink infotainment system, and OnStar with 4G LTE and wifi. Seeking out younger buyers is also sound business practice: Millennials now outnumber Baby Boomers as the largest single age group in the United States. Younger buyers also can improve a brand's image, which is another area where Chevy would like to improve. Chevy ranks 82nd on Interbrand's Best Global Brand's list, behind 11 other automakers. Apple is No. 1. "We need our own variation of the Genius Bar," Batey said. 2016 Alfa Romeo Giulia View 3 Photos Meanwhile, Alfa is in different shape.
