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.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

These are 2014's best-selling cars and trucks

Now that 2014 is no more than a set of numbers on spreadsheets, at last, the grist mill gets its first real load to chew on. The number one selling vehicle in America last year was the Ford F-Series, a fact that should surprise you only if your family name is Van Winkle and your naps tend to last 38 years, which is how long the Ford pickup has ruled our buying landscape. Even though series sales were down 1.3 percent, it still racked up 753,851 units. That's 2,065.3 sales per day, every day, all year. The Chevrolet Silverado, up 10.3 percent for the year, was still a daylight second at 529,755 units. The cab-and-bed love continued into third place with the Ram 1500-3500 trucks, gaining 23.6-percent year-on-year to clock 439,789 units. The robust turnout at The Bighorn and Jeep helped Fiat-Chrysler increase its sales by 16 percent, past the two-million mark. Our number one car? The Toyota Camry, staying in first place with a 4.9-percent sales boost to 428,606 sales, trailed again by the Honda Accord at number five with 388,374 sales. Accord sales rose six percent, and if it's any consolation to Honda for coming in second - not that it needs one - it is the only manufacturer to have three vehicles in the top ten. The rest of the list: the Nissan Altima with 335,644 sales (+4.7%), the Honda CR-V with 355,019 (+10.2%), the Toyota Corolla/Matrix combo with 339,498 (+5.9%), the Honda Civic with 325,981 (-3.1%), and the Ford Fusion with 306,860 sales (+2.9%). Total sales for the year were up six percent to 16.5 million vehicles, a volume not seen since 2006, aided by a strong December that was up by 11 percent year-on-year. Ford was the top selling brand overall but sales didn't really budge from 2013, while Subaru rocketed up 21 percent to finish with 513,693 sales. At the precious end, BMW, Audi, Porsche and Land Rover all had record years, and Kelley Blue Book thinks we could be looking at 17 million sales for the next two or three years.
