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!"

Why 2015 is going to be a huge year for trucks

Nissan chief executive Carlos Ghosn took center stage to introduce the 2016 Titan last week at the Detroit Auto Show. He spoke of the truck's new features, impressive Cummins V8 diesel engine and the extensive amount of time and money required to build a modern, competitive pickup truck. "We have done all of this because we see opportunity – an opportunity in the unmet needs of today's American truck customers," Ghosn said. He was speaking about the Titan, but his thoughts echo the industry's mindset: When it comes to trucks, find an opportunity and attack. Even with CAFE regulations looming and fickle consumer preferences, investing in trucks is a no-brainer for automakers. Some consumers will always need a truck for their job or lifestyle. And some people will always want one, whether they need it or not. With that in mind, here are four reasons why the pickup-truck sector is more important than ever and poised for growth in 2015. View 24 Photos The Nissan Titan Is Back Okay, it never left, but the Titan hadn't been redesigned since its launch in 2003, and Nissan sold more NV200s than Titans in 2014. It's an understatement to say the truck was languishing. That all changes with the 2016 model. The Titan will come in two variants, a traditional fullsize competitor and the Titan XD. The XD will lead the market launch, and it arrives late this year. It's pitched as a "whitespace" offering, Nissan sales and marketing vice president Fred Diaz said. The idea is to offer something in the general size and price range of a fullsize truck, but also have some of the capability of a heavy-duty truck. The XD uses a fully boxed ladder frame, the chassis design from Nissan's commercial division, and the wheelbase is about 20 inches longer than other Titan models. The XD, which Nissan is calling the flagship of the line, will be the only model with the 5.0-liter Cummins turbodiesel V8. It produces 310 horsepower and 555 pound-feet of torque, while being able to tow 12,000 pounds. V6 and V8 gasoline models will also be offered on the Titan XD and the standard, non-XD model. When production ramps up, the Titan will be sold with several cabs, beds and trims. New features include trailer sway control, an integrated trailer brake controller, more storage options in the cabin and even laminated front and rear side glass to reduce outside noise. All of this has given Nissan fresh confidence in an area where it admittedly has been lacking. "We can compete," Diaz told Autoblog.

2016 GMC Sierra All Terrain X is cool but no Raptor threat

If you want a brutish off-roader from Ford or Fiat Chrysler Automobiles, you're spoiled for choice. There's the F-150 SVT Raptor, the Jeep Wrangler, and the Ram Rebel and Power Wagon. But since General Motors killed the Hummer brand, it's been without any real competitor to those trucks. The new, special edition GMC Sierra All Terrain X is not going to be that vehicle, but it's close enough to be worth a look. The oft-overlooked Sierra All Terrain's off-road suspension and Eaton locking rear differential give it some real trail credentials. The All Terrain X builds on both with cosmetic and performance upgrades. For most owners, the big draw will be the brawnier 5.3-liter V8. Fitted with a performance exhaust, it should deliver a meatier tone, and according to GMC it bumps output up from 355 to 365 horsepower. The other big performance upgrade comes from the tires, knobby Goodyear Wrangler DuraTrac MT mud-terrain-rated things. The tires and their accompanying 18-inch black aluminum wheels are nice touches. Cool as the All Terrain X might be, it strikes us as an odd strategy for the GMC brand. For one, the trail-ready tires and performance exhaust of the All Terrain X don't seem to fit into the more premium market position that GMC occupies. Moreover, Chevy already has an off-road-oriented pickup in the new Colorado Z71 Trail Boss. Visual upgrades like the black bed-mounted sport bar, LED off-road lights, blacked-out accents, and the 18-inch wheels, the look of the All Terrain X is more in line with the Colorado Trail Boss theme. It's just our two cents, but it seems like attaching the All Terrain X's aesthetic to the Silverado would have been a stronger strategy, and would give Colorado buyers a larger off-road-focused truck to aspire to. You can look for the special edition All Terrain X in GMC dealers this spring, with prices to be announced closer to the on-sale date. Read on for the official press release from GMC.
