GMC Hummer EV heads north for winter

GMC announced early Tuesday that its new Hummer EV pickup is ready to head north for winter testing. What might seem like a trip in the wrong direction to us warm-blooded enthusiasts is a critical next step in the development of GM's new electric truck.  We also got a couple of teaser pics of the Hummer EV at GM's Milford Proving Grounds, along with two shots of development prototypes being assembled, of which GM says it has "a series." There's not much new to see here, but GM says there's more to come. "The GMC HUMMER EV has arrived at GM’s Milford Proving Grounds to continue validation tests and will head to northern Michigan to run through the teamÂ’s grueling winter testing process," GM said in its announcement. "We will document the journey and share updates in the coming weeks and months." The GMC HUMMER EV arrived at GM?s Milford Proving Grounds to c View 3 Photos The GMC Hummer EV Edition 1 will feature three electric motors, enabling torque vectoring. GMC says these motors produce 1,000 horsepower, though we don't yet have a final torque figure. Power comes from a 24-module Ultium battery pack which can provide an estimated 350 miles (or more) of range. GMC says this new architecture supports 800-volt fast charging up to 350 kW, which is comparable to the system Porsche introduced with its Taycan electric sedan, and GMC says it can replenish 100 miles of range in just 10 minutes. Planned variants include a two-motor setup, and an alternative 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 two feet and the capability to climb over an 18-inch vertical obstacle. Edition 1 Production begins late next year, with a starting price of $112,595. In fall 2022, we'll see the regular top trim starting at $99,995; In spring 2023, weÂ’ll get a mid-level trim that has three motors, air suspension and four-wheel steering -- but no torque vectoring -- starting at $89,995. 

GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

GMC Hummer EV First Drive Review | True supertruck, for better and for worse

Right from the start, the 2022 GMC Hummer EV has been advertised with superlatives, mostly in reference to its specifications. GMC has even called it a "supertruck" in its own materials. And while we've received a taste of the truck before, only now have we finally got our hands on the production-spec model, and had the opportunity to drive it both off-road and on the street. What we've found is that the Hummer EV is undoubtedly a supertruck, much the same way that a Ferrari or a Lamborghini is a supercar. It totally delivers on its incredible capabilities, but there are compromises. And they're worth being aware of before plunking down the more than $100,000 a first-year Hummer will run you. That six-figure truck is the version we tested, the Edition 1, which actually rings in at $112,595. It's the only version in production for now, with lower trims coming in the next couple years. It's sold out, but many of the features will be available on the next highest trim level, the EV 3X. Among those features are the three motors, torque vectoring, “Watts To Freedom” launch mode, four-wheel steering, removable glass roof panels, 35-inch tires, Super Cruise, power rear window and MultiPro tailgate. In other words, although you can literally no longer order an Edition 1, you can still order a Hummer EV with nearly the same specification. This content is hosted by a third party.

No one can resist seeing what 1,000 horsepower and 1,200 pound-feet of torque will feel like. It's even a tad more torque in Watts To Freedom mode, which preemptively runs the cooling system to enable the additional twist. That mode allows the Hummer to hit 60 mph in 3 seconds, and the drama is dialed up with visual, audible and haptic cues. But even without engaging launch mode, the Hummer EV impresses and delights with its acceleration. In addition to pinning you to the seat, the entire truck squats in an exaggerated fashion. It's absurd, especially considering the truck's curb weight that surpasses a truly astounding 9,000 pounds. ThatÂ’s several hundred pounds more than the heaviest GMC Sierra HD 3500 diesel dually. Of course, that weight, as well as the nature of electric motors, means the party starts to calm down as the speed increases. The weight is noticeable in other areas, too.
