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!"

GMC Terrain Nightfall Edition is murdered-out for the masses

We've lost track of how many special edition Chevrolet Silverado and GMC Sierra pickups there have been over the past few years. But while some special editions can be kitschy, there's nothing overtly bad about the GMC's Nightfall line. We've already seen the blacked-out look on Canyon Nightfall and Sierra All Terrain X pickups, and now, it's being applied to the Terrain. As with the trucks, the Terrain Nightfall's changes are simple: the chrome-heavy finish is replaced with gloss-black accents where applicable. That's what you'll find on the grille surround, the front and rear fascia accents, the license-plate surround, mirror caps, and roof rack. Like Jay Z said, all black everything. Except for the wheels, of course – those have machined faces with black spokes. The grille inserts aren't strictly black either (they're charcoal), and as counterintuitive as it may seem, owners can choose from three body paints in addition to Onyx Black (Summit White, Graphite Gray, and Crimson Red). The Terrain Nightfall Edition will be offered on the SLE-2 and SLT trims, with prices to be announced closer to its fall 2016 on-sale date. GMC Introduces 2017 Terrain Nightfall Edition The News Ahead of its debut at the New York International Auto Show, GMC today introduced the 2017 GMC Terrain Nightfall Edition – a stylized special edition combining blacked-out exterior details and wheels, with popular technologies such as IntelliLink with available 4G LTE connectivity and Wi-Fi hotspot. It joins the Canyon Nightfall Edition and the all-new Sierra All Terrain X as the latest GMC vehicle to offer an exclusive, personalized appearance with the Terrain's premium features and refinement. Product Details The Terrain Nightfall offers an edgy appearance with 18-inch machine-faced aluminum wheels and gloss black spokes, a charcoal grill with a gloss black surround and accents, gloss black front and rear fascia accents, gloss black rear license plate surround trim, gloss black outside mirrors and black luggage rails. Terrain Nightfall Edition will be offered on SLE-2 and SLT models with four exterior color options: Summit White, Onyx Black, Graphite Gray Metallic and Crimson Red Metallic. On Sale Fall 2016 Quotable "Building on its best year ever, Terrain continues to attract new and style-conscious customers to GMC," said Duncan Aldred, vice president of GMC Sales and Marketing.

New J.D. Power Initial Quality Study puts Porsche, GM in spotlight

J.D. Power and Associates has released its annual Initial Quality Study, and this year, Porsche and General Motors took the spotlight. The study, which asks new car owners to report problems experienced during the first 90 days of ownership, found that overall, the industry averages 113 problems per 100 vehicles.
Porsche managed a score of just 80 problems per 100 vehicles, while GMC took the second spot on the podium with 90. Lexus filled out the top three with 94 problems per 100 vehicles, followed by Infiniti at 95 and Chevrolet at 97. The study also looks at specific models, and found the Lexus LS to enjoy the best initial quality at 59 problems per 100 vehicles.
Interestingly enough, the report found that around two-thirds of most owner problems experienced in the first 90 days are attributable to vehicle design instead of mechanical failure. Specifically - echoing a refrain we've been hearing for the last few years - owners are having a hard time figuring out how to use the technology present in their new vehicles. Head over to the J.D.
