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!"

Mark Reuss: GM can't afford product 'misses,' has 'thought about' CT6 V-Series

Mark Reuss is a busy man. He oversees General Motors' global product portfolio, an all-encompassing task for a company that sold more than 9.9 million cars and trucks last year. When GM launches a well-received product, like the road-going rocket ship that is the Chevrolet Corvette Z06 – he gets credit. When the company stumbles with the slow-selling Chevy Malibu or grapples with fallout from the decade-old Saturn Ion and its flawed ignition switch, he gets blamed. GM owners, the press and sometimes the federal government, demand answers. Bob Lutz famously held the job before Reuss. So did Mary Barra, who's now GM's chief executive. There's a New GM, but the lineage is connected to a long history. When he's not thinking product, Reuss, an executive vice president, also runs the purchasing and supply chain for the company, which is still one of the largest industrial empires in the world. We caught up with Reuss on the floor of the New York Auto Show, where GM had just rolled out two crucial new products: the 2016 Cadillac CT6 and the 2016 Chevrolet Malibu. Speaking with a small group of reporters, Reuss delved into a variety of subjects, including the new Malibu, Cadillac's future (he thinks the ATS-V is going to "flame the M3 and M4"), and other topics. On fixing the Malibu: "We can't miss. We can't have those kinds of misses [like the previous generation] on our cars and crossovers and trucks. We can't do that. If we do that, we give a reason for someone to go buy something else. It's that simple. "On a car like the Malibu we have a chance to really fix all of that, which we have, and then lead. Then you've got a real opportunity there. So that's what we've really been focused on here – to fix those things." He later added: "We need that car here to transform Chevrolet desperately because it's the heart of the market. And when you think of Chevrolet, people will come back and think about what we did with the [new] Malibu and the Cruze... It's hugely important to us." On Cadillac: "If we go out and try and out-German the Germans, it's probably not going to work. We've got an opportunity here generationally where there's a lot of people younger than me that have parents that drove BMWs and Mercedes, and I think there's an opportunity there for those people to drive something different than what their parents did, and I think that's always been an opportunity in the auto industry if you look at the history of it.
