GMC Hummer EV SUV prototypes hit the trails in Moab

It seems like GMC's new Hummer EV pickup only just hit the market, but it's almost time to roll the hype train back through for the next installment: the SUV. GM President Mark Reuss shared images of some prototypes crawling on the rocks outside Moab in what he called "final testing validation" ahead of the SUV's projected arrival in showrooms some time in early 2023.  "With its aggressive 49-degree departure angle and tight turning radius of just 35.4-feet, the HUMMER EV SUV’s maneuverability, capability and performance make it an off-road supertruck," Reuss said in the post accompanying the photos. The over-the-river-and-through-the-woods routine depicted in the photos doesn't reveal much we don't already know about the forthcoming electric 4x4, but we can at least contextualize that 49-degree departure angle; the best you'll get from any Jeep Wrangler currently on sale is 40.4 degrees.  GMC's Hummer SUV will launch early next year with an 830-horsepower drivetrain, offering roughly 300 miles of driving range. Pricing will start at $105,595 before options. Later in 2023, GMC will release an EV2X variant with up to 625 horsepower, similar range and an $89,995 price tag.

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!"

Watch the live reveal of the 2014 Chevy Silverado and GMC Sierra [UPDATE]

UPDATE: The trucks have been revealed. Click here for all of the official details.
As promised, Chevrolet and GMC are offering a live webcast of the world premiere for the all-new 2014 Silverado 1500 and Sierra 1500. After being teased with spy shots and blurry images like the one above for ages, now is the time to see the trucks in the metal, for real (well, as 'real' as it gets on a webcast, at any rate).
Shift your eyes down just below to see the reveal as it happens, starting at 9:30 AM EST. We anticipate having loads of images full technical information to share after the webcast, too, so truck aficionados should stay tuned. We'll also be bringing you live images of both trucks too, when we see them on the show floor at next month's Detroit Auto Show.
