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.

Amelia Island 2013: Chevrolet Corvette Sting Ray from concepts to split windows

While this year marks 60 years of the Chevrolet Corvette, the 2013 Amelia Island Concours d'Elegance focused on one of the coupe's most sought after models, the 1963 Sting Ray. General Motors design boss Ed Welburn was on hand to show off the all-new C7 Corvette, but even the hard-edged styling of the 2014 Stingray couldn't take away from the beautiful 1963 models sitting out on the field.
In addition to the original Sting Ray and the 1959 Sting Ray Concept, some of the other classic 'Vettes included "Big Tank" racecars, an interesting cutaway coupe, a right-hand-drive Z06 and the attention-grabbing 1963 Corvette Rondine by Pininfarina. Another impressive Corvette was the 1964 Corvette XP-819 rear-engine prototype. Owner Mike Yager had the car finished as a driving chassis for this year's show, but promises the car will be back to its original glory in time for next year's event.

Recharge Wrap-up: Detroit Electric teaser video, Nissan Leaf is Good Housekeeping "Tried and Tested"

Detroit Electric has a new teaser video and has updated its brand in preparation of the introduction of the SP:01. The refreshed logo uses a blue and white color palette, and the company has also given its website a new look. The teaser video, which gives a sneak peek at the exterior of the SP:01, shows the car taking form in the midst of an electrical storm. Watch the video or learn more in the press release below. Abengoa is celebrating the grand opening of a commercial scale cellulosic ethanol plant in Hugoton, KS. When running at full scale, the refinery will produce up to 25 million gallons of ethanol a year. The plant will also generate enough electricity to power itself and put some back into the grid. Energy Secretary Ernest Moniz was on hand for the dedication, saying, "Every gallon of cellulosic ethanol produced and used to fuel our vehicles reduces the impact of harmful greenhouse gas emissions by greater than 60 percent as compared to conventional gasoline." Learn more at Energy.gov. Good Housekeeping has named the Nissan Leaf one of its "Tried and Tested" vehicles. The magazine called the Leaf SL its top "Roomy Electric" vehicle in its November issue. The magazine's research institute evaluated the EV based on track and road driving, ergonomics and convenience features. Good Housekeeping made note of the car's "impressive" range, but according to Nissan's Fred Diaz, "the real beauty of the Nissan Leaf is that it's roomy and, best of all, fun to drive."

It uses things like grains leftover from brewing Budweiser, food waste from a baseball stadium and sewage sludge to produce the gas through anaerobic digestion. The compressed gas can then be used to power cars like Chevrolet's Bi-fuel Impala, which goes on sale later this year. Chevrolet likens the situation to the Delorean time machine in the Back To The Future movie series, which uses garbage to fuel its fusion generator.
