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!"

Chevrolet Captiva looks mildly refreshed and ready for family duty

We showed you Chevrolet's major debut yesterday, the 2014 Corvette Stingray Convertible, but General Motors is making a big push for Bowtie consideration in Europe, so it's also introducing the updated Captiva crossover here at the Geneva Motor Show.
While still based on the same platform as North America's fleet-only Captiva Sport (which is effectively a rebadged Saturn Vue), the Captiva is available in both five- and seven-seat iterations, and it looks far more modern. That's particularly the case with this updated model, which features revamped front- and rear ends that include restyled bumpers, grilles and LED taillamps, among other changes.
As before, the midsize Theta-platform CUV will be available in both front- and all-wheel drive, and is expected to carry a range of four- and six-cylinder gasoline and diesel engines. Important US programming note: Chevrolet sources tell us that America's Captiva Sport will not receive these updates.

Chevy might've pulled out of NASCAR if it weren't for new Gen 6 car

We've been on the fence with NASCAR for some time now. On one hand, it's some of the closest racing anywhere in motorsports, with actual passing and door-handle-to-door-handle action as a matter of course. But on the other, it's become template racing - a personality-driven sport more about the drivers than any sort of loyalty to a particular automaker. The Car Of Tomorrow format really rammed that message home, with a racecar's identity coming down to little more than headlamp stickers slapped on the nose. That's not necessarily a bad thing in and of itself, but we've wondered for some time what's in it for the automakers, who pay big money to stay in a series that has had little increasingly little do with street car sales, let alone innovation.
Apparently General Motors was beginning to wonder the same thing. In a new ESPN report, Rick Hendrick, team owner of Hendrick Motorsports, suggests that GM would have seriously considered leaving NASCAR if it wasn't for the move away from the COT to the new Gen 6 racer. According to Hendrick, GM North America boss Mark Reuss spearheaded the charge away from the 2007 COT and toward a racecar with clearer automaker ties - cars like the new Chevrolet SS racer shown above.

Now, if we could just get more rear-wheel drive V8 coupes into showrooms....
