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!"

2024 GMC Sierra HD prices start at $46,295, increasing $100 to $2,500

After an online reveal in October of last year, prices for the 2024 GMC Sierra HD have crept online thanks to GM Authority. The upscale heavy duty pickup gains a new-look design and a more powerful turbodiesel V8 that boosts the tow ratings every HD buyer likes to keep up their sleeves like aces. The optional 6.6-liter turbodiesel Duramax V8 increases horsepower 25 ponies to 470 and torque by 65 twists to 975 pound-feet, both numbers matching the 2024 Chevrolet Silverado HD's diesel output. The torque comes with more useful delivery as well, GMC saying it increased low-end twist by about 25% thanks to a new turbocharger. Buyers who go for the 6.6-liter gas V8 will command 401 hp and 464 lb-ft. Both engines run output through a ten-speed automatic. One the gasser, the new gearbox replaces a six-speed auto. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), the 3500 HD capable of towing up 36,000 pounds. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic and Downpour Metallic. Configuration variables include Regular, Extended and Crew cabs, and Pro, SLE, SLT, AT4, AT4X, Denali and Denali Ultimate trims. The AT4X is late availability, the Denali Ultimate is new for 2024. The Denali Ultimate comes with the 6.6-liter turbodiesel V8, a trim-specific grille, 20-inch machined-aluminum wheels with high-gloss black accents, power-operated running boards, leather upholstery, wood interior trim, massaging front seats, a Kicker sound system and exterior emblems featuring Alaska's 20,310-foot Mount Denali.  Pricing is up by $100 to to $2,500 depending on trim.

GM renders new Chevy Colorado, GMC Canyon pickups

At a series of industry seminars in Traverse City, MI today, General Motors executive vice president Dan Ammann gifted us with our first glimpse of the upcoming midsize pickup range from Chevrolet and GMC.
Just two slivers of nose are all we can see of the soon-to-be announced Chevy Colorado and GMC Canyon, though the teaser image does make plain that the pair will follow the styling cues (at least up front) found on big brothers Silverado and Sierra.
GM hasn't given us much in the way of detail in its ultra-brief press release that accompanied the teaser image, which is to be expected. We're told only that the pair of trucks are designed to be "capable, versatile and fuel-efficient alternatives to full-size pickups" and that production will start sometime in 2014, at the Wentzville, MO assembly center.
