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 introduced

Read This: Auto Extremist advocates for Corvette as brand with multiple models [w/poll]

The 2014 Chevrolet Corvette really grinds Peter De Lorenzo's gears. Or, more accurately, the self-anointed Auto Extremist has an issue with what he sees as mismanagement of the legendary sports car by General Motors executives. In a new editorial on his website, De Lorenzo argues it's time to split Corvette off from Chevrolet to create an all-new brand, complete with a model range with at least three new takes on the sports car. Capable of fully leveraging the successes of the Corvette Racing program and brandishing the full might of GM's technical prowess, the Corvette brand would theoretically give Porsche something to sweat over.
Sure, that sounds like a party, but given GM's troubled track record when it comes to launching (let alone managing) brands, we say that's slippery slope that could just as easily end with the whole Corvette franchise in the scrap bin. Either way, the notion is certainly an interesting one. Head over to Auto Extremist to take in the full editorial, and then let us know what you think in Comments. Should GM split off its most storied nameplate?
