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 files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

Chevy Silverado Midnight Edition coming to Chicago

Between the GMC Canyon Nightfall Edition and Chevy Silverado Custom Sport, the truck divisions of General Motors had no lack of blacked-out custom pickups to showcase at the Detroit Auto Show this year. But now the General has announced one more. Called the Midnight Edition, for this special Silverado blacks out all the trim, including the grille, bumpers, headlamp bezels, tow hooks, fog lamps, side and beltline moldings, 19-inch wheels, bedliner and bowtie emblems. It's based on the Silverado 1500 with the Z71 package, so it also boasts an off-road suspension, locking rear differential, hill-descent control and trailering pack. While it was at it, Chevy has also thrown in rear park assist and power heated door mirrors. Buyers will be able to choose between double- or crew-cab models, but no more than 5,000 examples will be produced this year, each priced at a premium pegged between $1,595 and $1,995 (depending on the model). The Silverado Midnight edition debuts today at the National Automobile Dealers Association convention in San Francisco and will be showcased at the Chicago Auto Show next month, around the time that deliveries will commence. 2015 Silverado Midnight Edition is The New Black Monochrome appearance package to debut at NADA and Chicago Auto Show 2015-01-22 DETROIT – Truck fans know that nothing adds presence to a pickup like basic black. And Chevrolet is taking black to the next level with the Silverado Midnight special edition, on display starting today at the National Automobile Dealers Association Convention & Expo in San Francisco, and making its public debut February 14 at the Chicago Auto Show. Beginning with a black Silverado Z71, the Midnight special edition adds: - An all-black front end with body-colored grille, bumper, headlamp bezels, tow hooks and fog lamps; - Black side moldings and beltline moldings; - 18-inch black painted alloy wheels with Goodyear Wrangler Duratrac all-terrain tires; - Special Z71 badges on the doors; - A spray-in bedliner (black, of course); - And the finishing touches – black Chevrolet bowties front and rear. Like all 2015 Silverado 1500 Z71s, Midnight special editions include off-road suspension, a locking rear differential, Hill Descent Control and a trailering package. Midnight special editions also include rear park assist and heated, power-adjusted outside rear-view mirrors.
