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.

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

Chevrolet Silverado, GMC Sierra could get independent rear suspension

The Chevrolet Silverado and the GMC Sierra could reportedly receive a variant of the four-link independent rear suspension found under the new Tahoe and Suburban. While that's not a surprise, a recent report suggests electrification, not comfort, convinced General Motors to make the change. Replacing the time-tested solid rear axle with an independent suspension will improve comfort, handling and off-road prowess, while adding weight, and likely making the trucks a little bit more expensive. It's a fair trade-off, but GM Authority learned the real reason for the swap is that at least one of the pickups will spawn an electric model, and it's more difficult to package a bulky battery pack around a solid rear axle. The independent rear suspension takes up far less space, even if it has more moving parts. General Motors will build its first regular-production electric pickup on an evolution of the Silverado's T1 platform named BT1, according to the same source. The b stands for -- you guessed it -- batteries. The firm reportedly doesn't want to make two suspensions for cost reasons, so the independent setup will come standard regardless of whether the truck runs on gasoline, diesel, or electricity. As a bonus, Chevrolet and GMC could choose to offer their T1-based trucks with Magnetic Ride Control or an air suspension, options available on the 2021 Suburban and Tahoe. The independent rear suspension will also find its way to the next-generation GMC Yukon due to be revealed January 14, and to the 2021 Cadillac Escalade scheduled to make its debut February 4. The long-rumored, born-again Hummer will get it, too, because it will arrive as an electric model built on the BT1 platform. It's worth noting none of this is official, and General Motors has remained quiet about what's next for its new suspension design, and what will be under its electric truck's sheet metal. If the GM Authority report is accurate, the Silverado (pictured) and the Sierra could ditch their solid rear axle for the 2021 model year. The change will likely be accompanied by other tweaks inside and out. Featured Gallery 2019 Chevrolet Silverado 1500 View 16 Photos Chevrolet GMC Truck
