2023 GMC Sierra AT4X new AEV Edition's spirit animal is the Bison

GMC's newly redesigned 2023 Sierra is getting some equipment that might sound familiar to fans of the Chevrolet Colorado ZR2 formula that inspired it. Don't call it a "Bison," but the new Sierra AT4X AEV (American Expedition Vehicles) Edition sounds an awful lot like everybody's favorite bovine-themed midsize off-road pickup, and GMC says it will be its most off-road capable factory Sierra 1500 ever. If you're not familiar with the AT4X formula, it's already pretty robust. The GMC twin to the new Silverado ZR2 boasts Multimatic DSSV spool-valve dampers, improved ground clearance and approach/departure/breakover angles compared to the "standard" AT4, plus front and rear electronic locking differentials. The AEV Edition looks to the margins for additional improvement.  "The Sierra 1500 AT4X is an incredibly formidable platform when it comes to on- and off-road performance and capability,” said AEV CEO & founder Dave Harriton. “We took our signature approach to help elevate this truckÂ’s inherent off-road capability to the next level. We are confident customers will love the result." The standard AT4X already offers plenty of ground clearance (10.8 inches) and an approach angle of 25.5 degrees, departure angle of 23 degrees and breakover angle of 22.7 degrees. The AEV Edition bumps the ground clearance to 11.2 inches and its AEV-sourced stamped steel bumpers improve the approach angle to 32.5 degrees, departure angle to 23.4 degrees (compared to 23 degrees) and the breakover angle improves to 23 degrees.  "Our customers want an uncompromising combination of on-road technology and off-road capability," GMC boss Duncan Aldred said in the company's announcement. "Leveraging GMCÂ’s unwavering dedication to providing premium trucks and AEVÂ’s expertise in engineering and integrating performance-driven parts and accessories, this truck provides extreme capability, technology and comfort." The AEV Edition will ride on 33" mud-terrain tires wrapped around unique 18-inch AEV "Salta" wheels finished in gloss black. The front end was restyled to accommodate the AEV Edition's wheel and tire package (it was too big for the existing wheel wells, apparently) and front bumper.

2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.

Watch GM's new pickup crash its way to five-star NHTSA ratings

General Motors has just scored a big win with its Chevrolet Silverado and GMC Sierra pickup trucks, acing the National Highway Traffic Safety Administration New Car Assessment Program. The two full-size trucks had already netted a five-star Overall Vehicle Score in their crew-cab variants, but the new testing certifies them as five-star trucks in both regular and double-cab bodystyles, so GM's trucks offer top ratings across the board.
"Our incredibly capable trucks have been engineered to be some of the safest," Gay Kent, GM's general director of Vehicle Safety and Crashworthiness said. "We've designed the vehicle structure, strategically placed high-strength steel and developed the occupant restraint system to achieve high levels of safety performance."
The scores mark the Silverado and Sierra as the first pickups to net five-star scores since NHTSA beefed up their testing regime in 2011, a nice feather in GM's cap as it continues to slug out the pickup truck wars with crosstown rivals Ford and Ram.
