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 tinkering with Silverado, Sierra model mix amidst strong early sales

Variety, as they say, is the spice of life. That's a lesson that is currently being taught to General Motors, because despite a strong showing from its 2014 Chevrolet Silverado and GMC Sierra, the General's pickup sales still can't best those of cross-town rival Ford.
With 59,163 trucks moved, GM fell just over 1,000 units short of toppling Ford, and one of the main reasons for that, according to GM's chief sales analyst, was due to a lack of variety in the engines and body styles available on dealer lots. "We are still over-weighted toward crew-cab V8 trucks. Our light-duty mix will moderate over time as our launch progresses," said Kurt McNeil.
Loading dealers with the popular combination of the 5.3-liter V8 and the four-door, Crew Cab body style was intentional during the truck's launch, but as supplies of leftover 2013 models, which are being sold at heavy incentives, are beginning to wane, both budget-conscious and high-dollar buyers are looking elsewhere instead of at the volume model pickups.

Chevrolet considering midsize crossover to slot between Traverse and Equinox

Crossovers are the new hotness, and automakers are looking to cash in by offering a size and shape for every customer. With Chevrolet's debut of the new 2018 Traverse in Detroit, which grew ever so slightly compared to the first-generation model, there is now a midsize-crossover-sized hole between the three-row Traverse and the compact Equinox. When asked about that obvious space, a Chevrolet spokesperson told us the company is looking into the possibility of expanding its crossover lineup. It should be a relatively simple thing to do, since all it would take is reskinning and rechristening the GMC Acadia with a bow tie, and we all know how much GM loves platform sharing. Although they're now different sizes, the new Acadia and Traverse still use the same platform; the Acadia is now on a short-wheelbase version of the C1XX while the Traverse uses long-wheelbase C1XX parts. A short-wheelbase Chevy built on the C1XX likely would be differentiated visually from both the Acadia and the larger Traverse. It may seem like flooding the lineup with more and more models would cannibalize sales of existing ones, but Chevrolet said it would rather have customers stay within the brand rather than going to another automaker. There have been whispers that some form of the Blazer name (possibly TrailBlazer) may make a return on a midsizer, but if it does don't expect an old-school body-on-frame SUV like the old one. In the end, if Chevy builds it, customers will come. Related Video:
