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 also sheds parts from its pickups to boost payload ratings

The row between Ford and Ram over who boasts the best-in-class tow rating for heavy duty pickups has revealed a number of things. Chief among them is a report that Ford removes items like the spare tire, jack, radio and center console from its vehicles in a bid to lower its base curb weight and therefore keep the truck's gross vehicle weight rating down.
For those that need a refresher, GVWR is the vehicle's curb weight plus its maximum payload. A lower GVWR allows Ford to station its F-450 among the so-called Class III pickups, despite the fact that internally, it has the makings of a more brutish Class IV truck.
Ford explains away these deletions, saying a customer could order their vehicle in such a manner. It has also come to light that Ford is not the only automaker to engage in such practices.

Chevy Silverado edges Ram 1500 in Consumer Reports two-truck shootout

Forget Corvette versus Viper. When it comes to important head-to-head comparisons, fullsize trucks are where domestic automakers really care. And until the redesigned Ford F-150 makes its debut, the Chevrolet Silverado is going to have plenty to brag about thanks to a new Consumer Reports shootout against the Ram 1500.
It was a tight race among these V8-powered titans, but the all-new 2014 Silverado (and its GMC Sierra twin) barely edged out Ram's updated pickup with a score of 81 points - enough to make it the institute's top-rated fullsize truck on the market. Its narrow victory over the Ram, which finished just three points back, was due to its superior fuel economy, better towing and payload capacity and conveniences like a lower step-in height, easy-to-use tailgate and rear bumper steps that make loading and unloading less of a chore.
Importantly, CR notes that buyers with less heavy-duty truck needs might actually prefer the Ram over the Chevrolet, since its high points include a smoother ride thanks to its coil spring rear suspension, dominant infotainment system with Uconnect, and a big thumbs up for the available Hemi engine and eight-speed automatic transmission.
