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!"

GM to offer 2 years free maintance on most 2014 models

A day after Ford announced it was scaling back the complimentary maintenance program for its Lincoln brand, General Motors has gone in the completely opposite direction, offering most of its 2014 lineup with free maintenance. Since 2011, Cadillac models have all come with a four-year/50,000-mile complimentary maintenance program, but Chevrolet, Buick and GMC vehicles will now come standard with free maintenance for two years or 24,000 miles for the 2014 model year.
The program will give vehicle owners and lessees free oil changes, tire rotations and 27-point inspections following the recommended maintenance schedule laid out in each vehicle's owner's manual. We contacted GM to see which vehicles were eligible for the program, and a spokesperson got back to us with the following comment:
"All 2014 models are eligible, it's just that the included services vary by model, e.g., Spark EV would not need oil changes, Corvettes don't recommend tire rotations."

Weekly Recap: Auto execs face life in prison for recall delays under proposed legislation

The stiff punishments are part of broader transportation legislation, but clearly McCaskill has automakers in her sights.
Missouri Senator Claire McCaskill threw down the gauntlet this week, proposing a bill that could send auto executives to prison for life if they were found to have delayed a recall. She also wants to eliminate the limit for fines for auto safety violations, which are currently capped at $35 million.
