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!"

NHTSA could add 1M cars to GM recall

The Detroit Free Press is reporting that the National Highway Traffic Safety Administration may expand a recall campaign for faulty brake lamps. The agency is currently looking into complaints that certain 2004-2011 Chevrolet Malibu models as well as some 2007-2009 Saturn Aura sedans may have brake lights that do not illuminate when the driver presses the pedal. Alternatively, the lamps may also illuminate without input from the driver. General Motors recalled 8,000 Pontiac G6 models from the 2005 model year for the same problem, and NHTSA is currently investigating whether to add 550,000 more G6 models built between 2005 and 2009 to the list for the same issue.
In addition, investigators are currently examining 97 complaints from Malibu and Aura owners with the same trouble. If NHTSA adds those models to the recall campaign, more than one million units could be covered. GM, meanwhile, says there have been no accidents or injuries as a result of the problem.

2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.
