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!"

Chevy exec confirms SS production model reveal at Daytona on Feb 16

The 2014 Chevrolet SS will make its racing debut for the 2013 Daytona 500, but the production version of the car will get its official unveiling on February 16 in Daytona, a week before The Great American Race. According to a report by Automotive News, the reveal has been confirmed by Jim Campbell, Chevy's US vice president of performance and motorsports. With the departure of the Dodge Charger, the new Chevrolet racecar will be the only competitor to feature a V8, rear-wheel-drive layout in both street and NASCAR form.
NASCAR fans will be able to see the new fullsize performance-oriented sedan on display in the festivities leading up to the Daytona 500, but the car won't go on sale until later in the year. The Australian-built Chevy SS will be a low-volume performance model, and it will be priced above the 2014 Impala, which starts at $27,535.

GM veteran Bryan Nesbitt tapped to head Buick design
