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!"

What an Atlas-based Ford F-150 might look like

Just ahead of January's Detroit Auto Show, surprising rumors pegged Ford as revealing some sort of F-150 concept, perhaps as a hurried effort to deflate some of the buzz building around General Motors' new Chevrolet Silverado and GMC Sierra twins, which were also making their auto show debut. Those rumblings turned out to be true, as Ford rolled into the Motor City with its Atlas concept (inset, right), touting the truck's bold styling as a precursor to the next-generation F-Series.
The show truck featured all kinds of clever details, including active wheel shutters and a front air dam that raised and lowered to improve aerodynamics while preserving off-road ability. It also had a genuinely snarly face. And it's that pugnacious snout that may well be on its way to production. The good folks at TopSpeed have worked up the plausible-looking artist's rendering above by cross-referencing the Atlas concept with what little has been revealed from recent spy shots. The look is toned-down pretty dramatically from the concept truck, but its Atlas roots are clear, with a massive three-bar grille and bracket-shaped headlamps hiding a next-generation EcoBoost engine. In the rendering, the show truck's deeply contoured hood and roofline have been ditched and larger, more traditional side mirrors have been fitted - all likely concessions in the move to production sheetmetal.
While Ford has yet to officially announce when it will unveil the 2015 F-150, all signs point to next year's Detroit Auto Show - one year after the Atlas shrugged off GM's new pickups.

Ford won't be releasing GT500 lap times for the 'Ring, or any other car

Trucks have towing capacity, EVs have driving range and performance cars have Nürburgring lap times. What do all three have in common? They should all be taken with a grain of salt. Currently, there is no sanctioned way to record lap times or verify production-spec cars - a lesson we recently learned with the 2015 Nissan GT-R Nismo - and until there is a way to do so (and there probably never will be), we'll never officially know the actual time it took for Ford to lap the 'Ring with its ultra-powerful Shelby GT500.
After posting a Ford-made video of a 2013 GT500 running around the 'Ring, the guys over at SVTPerformance.com (an enthusiasts forum not affiliated with Ford or SVT) wanted more answers. They got in touch with Ford's Global Performance Vehicle Chief Engineer Jamal Hameedi, who said until there is a way to verify the times and inspect the cars, Ford will not get involved with lap-time wars. In the email, Hameedi pointed out that the 'Ring is a useful tool in that it allows a wide spectrum of track conditions, but until there is a governed way to record times, there is no way to accurately compare cars head-to-head.
And as much as some may not like it, Hameedi speaks the truth. It really isn't possible to compare times from one car to another, unless those cars were lapping the same track at the same time with the same driver. Not that any of this means there won't be continuous wars by fans and manufacturers alike... in other words, feel free to voice your opinions in the Comments below.
