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!"

Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

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.
