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.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

2015 Green Car Of The Year finalists announced, run alt-fuel gamut

The 2015 edition of the Green Car of the Year award is following right in the footsteps of previous years with a variety of alt-fuel powertrains making the just-announced finalists list. You've got your plug-in vehicle (the BMW i3), your compressed natural gas (the Chevy Impala Bi-Fuel), your high-efficiency diesel (the Audi A3 TDI), your 40+ mile-per-gallon gas engine (the Honda Fit) and, finally, a car that can do a little bit of everything (the VW Golf). The Golf is available – at least in some parts of the US – with three different powertrains: a 2.0-liter diesel, a gasoline engine and all-electric drive. The Impala can burn either natural gas or gasoline in its 3.6-liter engine. The A3 is an efficiency champ, able to get 73.5 mpg on some European tests. The i3 can be a pure electric vehicle or come with a short range extending engine. And the Fit brings 41 miles to the gallon in a practical, affordable package. The GCOY award is announced every year at the Los Angeles Auto Show by Green Car Journal. The committee doesn't just take the fuel-saving technology into account, but also a vehicle's "availability to the mass market." Last year, the Honda Accord Hybrid/Plug-In Hybrid won top honors, following up on wins from the Ford Fusion models (plug-in hybrid and hybrid) for 2013, the Honda Civic Natural Gas for 2012 and the Chevrolet Volt for 2011. FINALISTS ANNOUNCED FOR 2015 "GREEN CAR OF THE YEAR"" Green Car Journal to Reveal Winner of 10th Annual Award at LA Auto Show" Press & Trade Days, November 20 LOS ANGELES, CA (October 21, 2014) – Green Car Journal has announced its five finalists for the magazine's high-profile 2015 Green Car of the Year® program. The 2015 models include the Audi A3 TDI, BMW i3, Chevrolet Impala Bi-Fuel, Honda Fit, and VW Golf. The Green Car of the Year® award, an honor widely recognized as the auto industry's most important environmental accolade, celebrates its 10th anniversary this year. An increasing number of vehicle models are considered for the Green Car of the Year® program each year, a reflection of the auto industry's expanding efforts in offering new vehicles with higher efficiency and improved environmental impact. Green Car Journal has been honoring the most important "green" vehicles every year at the LA Auto Show, since its inaugural award announced at the show in 2005.
