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!"

Chevy working on production Impala Midnight Edition

To put together the Impala Blackout concept for SEMA, Chevrolet didn't need to go much further than its accessories catalog. The in-house connection is what could make it possible for Chevy to get a production version of the Blackout into dealers this model year, with its few bits of chrome trim and dark detailing on the 19-inch aluminum wheels set into an abyss of gloss black paint, black Bowtie, grille surround, rear spoiler and mirror caps. The interior is black leather, with stainless steel for the sill plates and pedals, and an 11-speaker Bose audio system, and it gets the optional 305-horsepower, 3.6-liter V6. The brand's marketing director for cars and crossovers, Steve Majoros, told Edmunds that it could come in late spring, and that it will be called "Midnight Edition." Majoros didn't give any indication of pricing or if the production car will be spec'd out like the concept. If you simply don't want to wait for late spring, you could work your DIY mojo by putting one together the same way Chevrolet did: give the accessories catalog a workout. Related Video:

GM and Isuzu to partner for medium-duty commercial truck

General Motors is returning to the medium-duty truck business in the US for the first time since 2009 thanks to a new deal with longtime-partner Isuzu. The arrangement brings the Isuzu N-series models to Chevrolet dealers with the Bowtie's branding on them in 2016. There are six medium-duty Chevy models arriving at dealers in regular cab and crew cab bodies: the 3500, 3500HD, 4500, 4500HD, 5500, and 5500HD. The trucks will be sold as a bare chassis for buyers to outfit to their needs. Depending on model, customers will have the choice of an Isuzu-sourced 3.0-liter and 5.2-liter diesel engines or a 6.0-liter V8 gasoline-fueled engine from GM and six-speed gearbox. According to company spokesperson Bob Wheeler to Autoblog, the diesel models will be built in Japan and the rest assembled from knockdown kits in Charlotte, MI. This kind of vehicle sharing isn't uncommon for GM in the commercial segment, and it already partners with Nissan to use the Japanese brand's NV200 as the City Express van. The General also once owned a significant stake in Isuzu, and the two have remained collaborators even since then. Isuzu and GM Enter Commercial Vehicle Collaboration Agreement in the U.S. 2015-06-15 DETROIT and FUJISAWA, Japan – General Motors Co. (NYSE: GM) and Isuzu Motors (TSE 7202) have reached an agreement on a U.S. commercial vehicle collaboration, allowing Isuzu to strengthen its product lineup and GM to expand its commercial vehicle portfolio.

To strengthen the product lineup, GM and Isuzu will explore the use of GM commercial vehicle components for Isuzu low cab forward trucks and GM will continue to produce and supply the 6.0L V-8 gas engine and six-speed transmission for Isuzu gasoline-powered low cab forward trucks. Isuzu and GM have maintained a strategic partnership for more than 40 years, producing collaborative business opportunities throughout the world.
