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 appears to repurpose Saturn Outlook parts on new Acadia

General Motors unveiled the company's refreshed GMC Acadia at the 2012 Chicago Auto Show yesterday, and if you were paying attention, you may have noticed something curious about the vehicle. While the new Acadia looks considerably better than its predecessor, a few components of the design looked more than a little familiar. Upon closer observation, it appears that GM has simply repurposed elements of the now defunct Saturn Outlook crossover on the 2013 Acadia. Both vehicles seem to share the same wrap-around rear glass, back hatch, tail light openings and exaggerated, squared-off fender arches.
While the vehicles are differentiated by badging, tail lamps and a rear valance, there's no denying the similarities toward the vehicle's rear. Up front, both share similar fenders, though adjustments have been made for the varying headlight designs.
That's good news if you just can't imagine life without the Saturn Outlook.
