GMC's Hummer EV will offer several powertrain options

General Motors confirmed plans to resurrect the Hummer nameplate on a GMC-badged electric pickup, and it's beginning to release details about the drivetrain that will power the model. Speaking to investors, company president Mark Reuss announced buyers will have at least three drivetrains to choose from at launch. The few specifications that have already been announced are impressive. GMC quoted a three-second sprint from zero to 60 mph, at least 1,000 horsepower, and 11,500 pound-feet of torque, though that latter figure undoubtedly corresponds to wheel torque rather than the powertrain's basic output. Most truck buyers don't need Lamborghini-rivaling acceleration, and they'd rather not pay for it, so GMC will also offer more basic versions of its Hummer. "When we go to market, we'll have one-, two-, and three-motor versions offering different ranges, different performance, and different price points to meet customers wherever they may be. If the customer wants a basic package, we'll have that. If the customer wants true off-road capability, and towing capability, we'll have that, too," Reuss said. He stopped short of revealing additional specifications about each configuration. While that sounds expensive to develop and certify, Reuss explained General Motors is keeping costs in check by making the Hummer's powertrain as modular as possible. He compared the platform to an ice cube tray. Its overall dimensions are fixed, but people can choose how many rows they fill with water. What he's likely alluding to is a scalable battery pack whose capacity can be increased or decreased by adding or removing cell packs. As for the motors, we're expecting the entry-level, rear-wheel drive Hummer will come standard with a single motor mounted over the rear axle. The mid-range variant will likely gain a second motor positioned over the front axle to deliver through-the-road all-wheel drive, and the range-topping trim will receive individual rear motors (though they won't be integrated into the wheels) for jaw-dropping performance, and improved off-road capacity.  Economies of scale will come into play, too. While the Hummer is the only electric off-roader whose launch has been confirmed by General Motors, Reuss stated the company's other brands will benefit from it, too. "We'll have a complete lineup of EVs, including the [Hummer EV] and its stablemates," he said.

GMC Hummer EV recalled over improperly sealed battery pack

Over 700 units of the GMC Hummer EV built during the 2022 and 2023 model years will be recalled due to an improperly sealed battery pack that lets water in. The firm issued a stop-delivery order at the same time as the recall, and it hasn't found how to fix the problem yet. Assigned recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 735 examples of the Hummer EV and 89 units of the BrightDrop Zevo 600 van. These two vehicles are pegged on opposite ends of the automotive spectrum, but they're affected by the same problem: "the high-voltage battery pack enclosure in some of these vehicles may not have been properly sealed," GMC notes, adding that "flanges on the battery pack enclosure may not have been properly primed or electrocoated." Water can wreak havoc in a high-voltage battery pack. GMC told NHTSA that it has found three EVs with this problem: an internal test vehicle that lost power while driving and two customer-owned vehicles that wouldn't start. As of writing, the firm is not aware of any accidents, injuries, or fires related to the issue, and GMC estimates that only about 1% of the recalled EVs are affected. GMC began notifying dealers of the recall in October 2022, and it plans to start reaching out to owners on November 28, 2022. However, a fix hasn't been found yet. In the meantime, the company issued a stop-delivery order and asked dealers not to attempt their own repairs. This isn't the Hummer EV's first run-in with water-related problems. In August 2022, General Motors voluntarily recalled 424 units of the Hummer EV and the Zevo 600 van due to a high-voltage connector that can prematurely corrode. The problem also let water leak into the battery pack, though it sounds like fixing it was reasonably straight-forward and involved applying sealant to the connector.

Humvee reborn on the battlefield... with a chimney?!

The military's High Mobility Multipurpose Wheeled Vehicle (HMMWV), better known to most of us as the Humvee, has already served a long and distinguished career in the battlefield, and there have been a number of replacements waiting in the wings to take over where the HMMWV left off. Or, should we say, leaves off... assuming that ever happens.
It seems that the Humvee is set to get a new lease on life as military budget constraints are forcing the government to reconsider its replacement. But there are still some pesky safety issues to work out before American soldiers will feel comfortable inside the confines of the off-road box on wheels.
As you're likely aware, improvised explosive devices are an ever-increasing threat to the lives of American troops serving overseas. The Humvee, which traces its design all the way back to the year 1984 when it first saw duty as a replacement for the long-running series of military Jeeps, has seen a number of incarnations over the years that added armor and improved safety, but the latest version may feature something hitherto unseen: a chimney.
