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 Silverado and GMC Sierra show all their sides in Detroit

There could hardly be more riding on the next-generation General Motors full-size pickup trucks, so the automaker has wisely made sure to have a selection of different models on hand at the Detroit Auto Show to show off. The 2014 Chevrolet Silverado and 2014 GMC Sierra were both officially introduced last month at a stand-alone reveal, and now they'll be on display for the public to see in various body configurations and trim levels.
The Silverado LTZ Crew Cab and Sierra SLE Extended Cab are aimed at providing more of a high-end pickup experience, while the Silverado LT Z71 Extended Cab and Sierra SLT Z71 Crew Cab should have off-road fans scouting out their favorite trails. The crew cab trucks won't go into production until sometime during the second quarter of this year - with other bodystyles coming later in the year - but we have plenty of live images from Detroit for you to enjoy.

Why the Corvette is Chevrolet's billion-dollar baby

Edmunds has worked up a piece that tries to figure out just how much the global Chevrolet Corvette economy is worth, a spitballed guesstimate putting the number at more than $2.5 billion with the proviso that the number is probably low. It starts by taking Corvette's new car sales of 14,132 units last year, which would equate to $714,725,900 (including destination) assuming ever car sold was a base coupe with no options. In the final tally, a little extra padding gets that number up to $750,000,000.
But that's not all. Consider this: Many of the almost 1.4 million Corvettes produced over the model's history are still on the road. There are new parts being produced and aftermarket companies like Mid-America Motorworks deaing business, that single Illinois company doing more than $40 million a year in sales. There are the Corvette events large and small, restorers who do nothing but Corvettes, salvage yards that deal only in used Corvette parts and the Corvette magazines where owners find all this stuff.
And then there are the Corvette-themed tchotchkes, every single one of which provides a tiny contribution to the huge licensing royalties that General Motors collects every year. The article admits there's no way to come to an accurate number, but it just goes to show how valuable one specific model can be to a company.
