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 Canyon AT4 OVRLANDX concept previews potential Bison-like model

GMC is signaling a move into serious off-road territory with this Canyon AT4 OVRLANDX concept. As its name suggest, this one-off was put together as a demonstration of what an overland-style GMC midsizer could potentially look like, but a glance beneath the surface reveals the bones of what we expect to be the forthcoming Canyon AT4X.  While "AT4" has been trickling down through the GMC lineup for the past few model years, AT4X kicks the basic off-road formula up a notch, a la Chevrolet's Colorado ZR2, which gains extra underbody protection, locking front and rear differentials and Multimatic's phenomenal DSSV dampers.  GMC Canyon AT4 OVRLANDX Off-Road Concept View 23 Photos OVRLANDX takes that to the next level, borrowing (and building upon) cues from the even-more-rugged ZR2 Bison, including rocker panel guards, cast-iron control arms, a custom front bumper with an integrated winch, built-in front recovery points, wheel arch trim with integrated LED task lighting, and guy lines for protecting the windshield from low-hanging branches. The custom rear bumper is even from American Expedition Vehicles (AEV), with whom Chevy partnered to produce the Bison's unique exterior bits. Does that seem like a wink and nod to you? “We wanted to showcase GMC Canyon with this concept and punctuate GMCÂ’s commitment to premium, off-road capable vehicles,” said Buick & GMC Global Vice President Duncan Aldred. "Consumer reaction to this conceptÂ’s design will help us further serve the growing market of buyers leading authentic outdoor lifestyles." This content is hosted by a third party.

In a way, the roof-mounted tent, awning, cooler and kitchenette are just there to disguise the fact that GMC will likely build a production pickup with much these same specs when the new model debuts for the 2023 or 2024 model year – or perhaps even sooner. While this concept is built around GM's existing 3.6-liter V6 powertrain, the redesigned Canyon is expected to be offered with just one engine: a 2.7-liter turbocharged four-cylinder lifted from the Silverado and Sierra pickups.  Rumors have pointed to a GMC variant of the Colorado ZR2 since the midsize pickup adopted the AT4 branding for its off-road variant.

2020 GMC Sierra HD pricing announced

Just as with its Chevy twin, pricing for the 2020 GMC Sierra HD has been revealed. Unlike the Chevy, though, prices haven't dropped across the board. The ultimate base prices for the 2500 HD and 3500 HD are technically less than the 2019 models at $37,195 and $38,395 respectively, but that's because those are the reintroduced regular cab models. Matching up the body styles of the last year's cheapest Sierras with their new equivalents, and the prices have crept up a few hundred dollars. But the next highest trim level, SLE, drops in price by nearly $2,000 between equivalent trucks. Equivalent SLT trucks are up nearly $2,000 each, though, and the base Denalis have gone up by about $7,000. This is due in part to the 2020 Sierra Denali no longer being offered with two-wheel drive. Comparing the old and new four-wheel drive models, the price is still up by about $4,000. While the new Sierra HD is only more affordable than the last one in certain circumstances, they all feature more capability. The standard 6.0-liter gas-powered V8 makes an extra 41 horsepower and 84 pound-feet of torque than the old one for a total of 401 horsepower and 464 pound-feet of torque. The 6.6-liter diesel V8 still makes 445 horsepower and 910 pound-feet of torque, but it now gets a 10-speed automatic transmission. Maximum fifth-wheel towing has increased, too. For the 2500, that number jumps from 15,400 pounds to 18,500 in the new model. For the 3500, fifth-wheel towing goes from 23,100 pounds to 35,500 pounds for the new truck. And of course, you can get GMC's fancy MultiPro tailgate on the new Sierra HD. One final note on the Sierra HD's pricing: it has the highest base price of the full-size heavy duty trucks. The Ford F-250 Super Duty is the cheapest at $34,745 and is closely followed by the Ram 2500 at $35,090. The full range of GMC Sierra HD pricing is listed below: Sierra 2500 HD Regular Cab Sierra: $37,195 SLE: $41,595 Double Cab Sierra: $39,795 SLE: $43,595 SLT: $52,195 Crew Cab Sierra: $41,595 SLE: $45,395 SLT: $53,995 AT4: $59,295 Denali: $65,295 Sierra 3500 HD Regular Cab Sierra: $38,395 SLE: $42,795 Double Cab Sierra: $41,195 SLE: $44,995 Crew Cab Sierra: $42,795 SLE: $46,595 SLT: $55,195 AT4: $60,495 Denali: $66,495 Update: The estimation of price difference between 2019 and 2020 Sierra Denalis has been corrected. Additional clarification of Denali price changes has also been added.
