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 considers adding more vehicles to broaden product line

GMC is considering expanding its product portfolio in the next 10 years to allow it to reach more potential buyers and grow sales, a top executive said Monday. The small and midsize sport-utility-vehicle segments are two possibilities, said Duncan Aldred, GMC sales and marketing vice president. He also said GMC won't make a car, preferring to reinforce its reputation as a maker of trucks and SUVs. "There's plenty of opportunities even if we define ourselves as a we do as a truck and crossover brand," he said. He wouldn't comment on the possibility of adding a Jeep Wrangler-fighter, though rumors have swirled for months that GMC is considering a product to compete with the iconic off-roader. "I can't confirm that ... everything's on the table," he said. He also said that it's possible GMC could get a unique set of underpinnings – all of its vehicles share platforms that are also used by Chevrolet – but it's not needed to differentiate his brand. "I'm very happy sharing underpinnings and everything else," he said. "All of the good-performing automakers do that." Speaking to journalists at a roundtable at General Motors headquarters in Detroit, Aldred said GMC received an investment from GM that is double what the brand has historically spent to fund its growth plans. Advertising spending alone will increase 50 percent this year compared with 2014. The brand rolled out a new ad campaign on Monday, called "Precision," that will underscore attention-to-detail and the premium features of GMC vehicles. Two of the commercials have a sporting theme, and the third focuses on modern menswear. GMC called it a "contemporary interpretation" of the brand's traditional positioning, and it will also continue to use its long-running "Professional Grade" tagline. The premium positioning of the ads come as buyers are increasingly outfitting their trucks as near-luxury vehicles. The percentage of buyers opting for the top-end Denali trim has increased from 17 percent in the middle of 2014 to 21 percent now. The goal is to get Denali to make up 25 percent of GMC sales by the end of 2017, Aldred said. Spurred by the higher Denali take-rate, the brand's transaction prices leapt by $3,000 last year. "It's [Denali] really kind of this jewel in the crown," Aldred said. GMC sales increased 11.3 percent in 2014 to 501,853 units, making it GM's-second-best-selling brand behind Chevrolet.

GM trademarks 'GearOn,' possibly for pickups

On May 27, a week before General Motors applied for a trademark for the word "Zora," GM filed a trademark application at the US Patent and Trademark Office for "GearOn," characterized as a "truck bed cargo system comprised of tiered storage cross rails, utility rack stanchions, cargo dividers and cargo tie down rings."
We have no idea what it will be or if we'll see it used on anything, but GM Authority reckons it could be GM's name for a pickup truck feature to rival the BoxLink system Ford introduced on the 2015 F-150. BoxLink has been described as having "dozens of configurations of stowable cargo ramps and lockable die-cast aluminum tie-down cleats," giving owners the ability to arrange the bed in they way they need and load unwieldy items like motorcycles without needing extra equipment.
Getting purely speculative, a month ago GM pickup truck engineers said there would be more and more regular updates for the Chevrolet Silverado and GMC Sierra starting next year. Beyond the suspected capability and fuel economy changes GearOn could be one of the "neat things coming in a whole host of areas."
