GMC Hummer EV revealed as a 1,000-hp, 350-mile, fast-charging beast

The 2022 GMC Hummer EV has finally been revealed, and it certainly looks the part. It has chunky, squared-off styling, big tires pushed to the edges, and a towering fascia. But it’s not a case of form over function. On the contrary, the Hummer EV is has some pretty wicked technology and gear under the skin. The first version of the Hummer EV that will be available is the tricked-out Edition 1. It features three electric motors, which allows for torque vectoring. These motors make 1,000 horsepower, though GMC still hasnÂ’t given real-world torque numbers. The motors are fed by a 24-module Ultium battery pack. The pack can provide an estimated 350 miles or more of range. Not only that, but it supports 800-volt fast charging up to 350 kW. ThatÂ’s comparable to PorscheÂ’s charging system, and GMC says it can add an extra 100 miles of range in just 10 minutes. Later, a two-motor Hummer EV and a three-motor version without torque vectoring. The Hummer EV rides on fully independent suspension with adaptive air shocks. They can provide continuous damping adjustments for comfort, and have a height adjustment range of 6 inches. When set in its max-height off-road mode, it has two additional inches of ground clearance, and the "Extract Mode" will lift it six inches higher than default. The Edition 1 model also comes with standard 35-inch mud terrain tires, and combined with the suspension, the Hummer EV has a fording depth of 2 feet and the capability to climb over an 18-inch vertical obstacle. Owners will be able to easily add more clearance since GMC made the wheel arches large enough to accommodate aftermarket 37-inch tires. Additional off-road goodies include skid plates along the chassis, rock sliders, the previously covered four-wheel steering with Crab Mode diagonal driving, and 18 camera views including angles under the truck for getting over rocks. Those cameras feature sprayers, too to keep them clean. Detailed information on torque output, torque vectoring, tire pressure, vehicle angles and more are also displayed on the infotainment screen. Speaking of that infotainment screen, itÂ’s a massive 13.4 inches and is paired with a 12.3-inch instrument display. They feature proudly in a squared-off, rugged-looking interior. The Hummer EV will get the latest version of Super Cruise, complete with automatic lane-changing. The Edition 1 gets the removable roof panels as standard, and those roof panels are clear, so you can still get some sun with them in place.

GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

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!"
