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!"

2017 GMC Acadia comes into focus

The future slate of crossovers from General Motors reportedly ride on the company's new, scalable Chi platform. With short- or long-wheelbase configurations possible, the chassis conceivably allows the automaker to be more adaptable in the configuration of its CUVs. Cadillac already appears to be testing Chi for the luxury brand's future SRX/XT5, and here it is again under heavy camouflage underpinning the next GMC Acadia. Unfortunately, the Acadia is so well concealed here that it's extremely difficult to pick out any of the styling changes, though the squared-off fenders and faint GMC logo peaking through the tape on the front wheels reveal what this vehicle is. Up front, the grille appears to sit somewhat lower than the current model, and the vertical LED running lights are easy to pick out. The orientation of the taillights through the camo suggests wraparound units not too dissimilar from the current Acadia (or is that Saturn Outlook?). The next-gen Acadia is expected to debut in 2016 as a 2017 model year vehicle. The powertrain options may include the current 3.6-liter V6, a four-cylinder and possibly even a turbo V6, and GM's new nine-speed automatic might also be for offer. With a year before the reveal, take a look at these photos for a first look.

GMC and EarthCruiser to collaborate on Hummer EV Pickup overlander project

GMC just announced a collaboration with overlanding vehicle builder EarthCruiser, and the end result is going to provide us with a co-developed Hummer EV Pickup. The photo you’re looking at above is the first teaser for whatÂ’s to come of the partnership. The Hummer team will be working with EarthCruiserÂ’s research and design division to develop an overland upfit solution for EVs that it says will initially be integrated into the Hummer EV Pickup. In case you werenÂ’t familiar with EarthCruiser, theyÂ’re the people that have made utterly wild overlanding vehicles like the Terranova, FX and EXP. Needless to say, EarthCruiser makes some pretty rad stuff, and none of it is cheap. GMC says this collaboration will look to use EarthCruiserÂ’s expertise gained from developing its vehicles to create an overlanding solution for the Hummer. We should expect to see EarthCruiserÂ’s engineering technologies integrated into the vehicle, which will allow the Hummer to go even further off-road and provide the ability for owners to live with their trucks in the wilderness.  The one snag with overlanding in EVs is the typically long journeys away from civilization. As an example, the EarthCruiser XP and EXP feature 60-gallon fuel tanks to ensure you can get to where you need to go and power the living situation for a long time once youÂ’re there. WeÂ’ll be interested to hear what GMC and EarthCruiser have to say about the challenges presented by overlanding in an EV. Already visible in the teaser image is what looks like a solar panel-filled roof and rear side pods for supplies. The concept truck will be presented in late summer 2023, and while no date for a production vehicle was provided, itÂ’s likely that the final truck will come soon after. Related video:
