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 readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

GMC has received 65,000 Hummer EV orders so far

The GMC Hummer pickup truck only just went on sale, and already there's word from company brass that demand is higher than expected. According to a report from CNBC, Duncan Aldred, global vice president of GMC, said the automaker has received more than 65,000 combined orders for the current electric truck and upcoming SUV. What's more, the number of customers converting reservations into orders is humming along at 95%, which is also higher than the company projected. "Production’s actually slightly ahead of plan and weÂ’re putting things in place now to actually expedite that as well, so we can deliver these reservations quicker than we originally thought," Aldred said, adding that new orders placed today probably won't result in a delivered vehicle until 2024. "WeÂ’re doing all the studies on that and weÂ’re confident we can go a lot quicker than we originally thought," Aldred said, "But it still means a reservation now probably means delivering in Â’24." The version of the Hummer pickup that's currently being built is the highest-spec Edition 1 model. That truck ran at least $110,295, but since it's already sold out, new customers will be looking at Hummer EV 3X that starts right around the $100,000 mark before any optional equipment is added (and assuming you can find a dealer that won't try to jack up the price). At some unspecified point in the next year or so, GMC will start building a lower-cost Hummer 2X for $89,995. A year or so later, the  $79,995 Hummer EV 2 will make its debut.
