GM mulling off-road variants of fullsize SUVs

According to General Motors, owners "just love off-roading with [its fullsize body-on-frame sport utility vehicles]," namely the 2015 Chevrolet Tahoe and Suburban and GMC Yukon. If that's the case, it's a bit odd that sales of the previous generation of these models with the Z71 off-road package didn't sell particularly well.
Perhaps, considering this disconnect between owner's thoughts and desires with actual sales, it's not surprising that General Motors is reportedly "considering" an off-road specific model. That means the package would include styling changes and badges along with suspension modifications and larger wheels with appropriately sized fender flares.
There's no indication if the off-road model would be called Z71 or when it may potentially go on sale, assuming it ever goes on sale at all.

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!"
