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!"

GMC Canyon will debut in Detroit

With the debut of the Chevrolet Colorado at November's Los Angeles Auto Show, perhaps it was only a matter of time before we saw the small truck's GMC counterpart. That time will be January, as we've received official confirmation that the GMC Canyon will be revived at next month's North American International Auto Show in Detroit.
The news came in the latest issue of the Detroit Auto Show's newsletter, NAIAS Connect. The article hasn't been posted online quite yet, but it details the Canyon as one of the world production debuts slated for the show.
While we've heard rumors that the Canyon would arrive in Detroit, this is our first concrete bit of evidence. As we've detailed before, we expect the Canyon to be stylistically quite different than the Colorado, though the underpinnings will be shared. The teaser image we have above is currently our only look at the new truck. We'll hopefully have more details in the next few weeks as the GMC Canyon draws closer to its official debut.

2015 Chevy Colorado and GMC Canyon order guides reveal added power

General Motors' Fleet Order Guide system is often the canary in the coal mine for interesting changes on new models. The recent guide for the 2015 Corvette unveiled all sorts of changes that weren't yet known about the sports car. Now, it's time for the 2015 Chevrolet Colorado and GMC Canyon to take their bow in the spotlight, and they look worth the wait. The new midsize trucks are getting a touch more power than first thought, as well as some very nice features.
Extended Cab models of both trucks come standard with a 2.5-liter, direct-injected four-cylinder rated at 200 horsepower at 6,300 rpm and 191 pound-feet of torque at 4,400 rpm. That's a bit more than the 193 hp and 184 lb-ft originally reported for the duo. The standard transmission for the extended trucks is a six-speed manual, but the Work Truck trim is also available with an optional six-speed automatic. Towing for the four-cylinder is rated at 3,500 pounds.
Crew Cab models come standard with a 3.6-liter V6 with 305 hp at 6,800 rpm and 269 lb-ft of torque at 4,300 rpm, with a six-speed automatic. That's also somewhat different than the originally reported rating of 302 hp and 270 lb-ft. Towing for the V6 is rated at 7,000 pounds.
