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!"

2014 Chevrolet Corvette Stingray Convertible gives us a couple of looks

Put away your pixel paintbrushes, kids. Pack up your Photoshop. This is the real-deal 2014 Chevrolet Corvette Stingray Convertible in its first official images. The droptop Chevrolet will roll into the bright lights of the Palexpo exhibition at next week's Geneva Motor Show, a four-wheeled statement of intent that General Motors is serious about taking its Corvette franchise global.
Chevy isn't providing anything in the way of further details with these two shots, but we've learned at least a couple of things about the car shown here. First off, the example seen in these images is fitted with the optional Z51 Performance Package - something that isn't immediately evident because there's no sign of the coupe model's prominent ductwork on its rear haunches. In order to accommodate the power folding hard tonneau cover, the vents that feed the transmission and differential coolers have been relocated to the underside of the car. The dark paint color on this example also does a good job of muting the contrasting black front fender vents and hood opening - Z51-spec design details that have proven to be somewhat controversial.
One other thing to note: These two shots also display the Stingray wearing different alloy wheels than the split five-spoke design shown at the hardtop's Detroit Auto Show unveiling in January. The simpler, thin five-spoke wheels should do a good job of showing off the Z51's upgraded brakes, and they'll be optional on the coupe as well.
