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!"

GM throttles back Chevy Malibu, Buick LaCrosse production over swollen inventories

As inventory of the Chevrolet Malibu and Buick LaCrosse continues to pile up, General Motors will be idling its Fairfax Assembly Plant for two weeks, according to Automotive News. This move comes about a month after the plant was shut down for three weeks in late December and early January for the same reason. As of January 31, the GM had a 94-day supply of Malibu stock while the LaCrosse was a little worse with a 117-day supply.
Just last week, GM announced that it would be investing $600 million in upgrading this plant, but it's unclear what future plans the company has in store for Fairfax considering slow sales of both the plant's models. We do expect a refreshed and more luxurious LaCrosse shortly and an early design update for the Malibu to be announced at some point this year, although we have had no official word as to when either will happen.

Automakers score 8 out of top 20 most-watched ads on YouTube [w/videos]

Who would have ever thought there'd be a day where people are able to skip television commercials only to go to websites to watch them later? Such is the joy of a DVR and YouTube. AdWeek tabulated the 20 most-watched ads on YouTube, and found that nine were car-related including eight coming from automakers.
Volkswagen continued its Star Wars theme with two ads in the top 20, including the highest-ranking car commercial The Bark Side spot at number three with almost 18 million views, which doesn't even have a single car in it. Some of our favorites are from Chrysler with Clint Eastwood in It's Halftime in America and House Arrest with Charlie Sheen for the Fiat 500 Abarth. Chevrolet, Honda, Audi and Toyota were the other automakers in the top 20, but we'd be remiss if we didn't at least mention one of the coolest ads on the list, the Hot Wheels corkscrew jump.
Of all the car videos, only the Fiat ad wasn't played during a Super Bowl. Check out all eight videos - in order - after the jump. Nike took the top spot with its My Time is Now ad that has been seen online more than 20 million times with Pepsi's Uncle Drew posted up in the runner-up; some of the other videos include four Old Spice commercials and an ad in which Snoop Dogg is pedaling Hot Pockets.
