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!"

Corvette Stingray Shooting Brake under consideration by Callaway [w/poll]

Callaway has released a few renderings of a design study for a shooting brake version of the C7 Chevrolet Corvette Stingray. The company says it wants to create a long-roof version of America's sports car to offer buyers more interior room and a vehicle with "unique style." The company says it will use structural carbon fiber for the new body bits, which suggests the conversion shouldn't add too much more weight to the Corvette. Along with a few mechanical tweaks, the Callaway Corvette Stingray AeroWagon could breeze past the 200 miles per hour barrier.
Provided that they get enough interest, Callaway estimates they will be able to effect the changes on the Chevrolet for around $15,000, and says the conversion work should be available through its network of dealers. You can check out the brief press release below for more information, or head over to the Callaway site to plunk down a deposit - but before you do, we want to know... do you find this C7 wagon interesting?

Hot Wheels Camaro to make big debut at Indy

Chevrolet handed over the keys to 33 Hot Wheels Camaro Convertible Indianapolis 500 festival cars this week. Race directors get the luxury of driving the droptops around Indianapolis in an ongoing tradition with roots all the way back to the 1960s. The stunt is supposed to remind area residents that the Indy 500 is right around the corner. The cars are our first look at the special Camaro Hot Wheels Edition in convertible form, and they are slated to head to dealers after a one-time production run. The cars also represent the first time in history full-size Hot Wheels have been offered for sale by an automaker.
The cars will be available in both the previously seen coupe bodystyle and this convertible configuration, and will feature metallic blue paint and special wheels with the iconic redline accent. Buyers will be able to choose between the V6-powered 2LT trim and the V8-powered 2SS guise.
Hot Wheels says the original Custom Camaro toy was one of the original 16 1:64-scale diecasts, and it remains one of the company's most valuable collector items today.
