GMC explains why the Hummer EV SUV has only 830 horsepower

GMC's 2022 Hummer EV pickup made its debut in late 2020 with a headline-grabbing 1,000-horsepower rating. Its SUV sibling broke cover yesterday with 170 fewer horses, so GMC executives had some explaining to do. Al Oppenheiser, the EV's chief engineer, pointed out that the SUV's wheelbase is about nine inches shorter than the truck's, which is called an "SUT" in GMC-speak. It's also about 20 inches shorter overall. Size matters in the electric car world; GMC can't stuff the SUT's big battery pack in the more compact SUV, and this directly influences power. He added that it would have been possible to build a 1,000-horsepower SUV by making changes to the battery pack's layout. His team would have needed to reduce cargo capacity and get rid of the flat loading floor, which were compromises that engineers were not prepared to make. Ultimately, 830 horses should be plenty for most drivers. "Frankly, we are not sorry that it's only 830 horsepower. There aren't many internal combustion engines that can say that. Will we be able to grow horsepower in the future? We are going to push that capability, and as the technology gets to the point where our batteries are smaller and more efficient, we will improve performance with any chance we get," Oppenheiser said. It helps that the Ultium battery technology GMC uses is extremely modular. Less powerful versions of the Hummer SUV are in the cards, too. At launch in early 2023, the model will exclusively be offered with the aforementioned 830-horsepower drivetrain, which offers around 300 miles of driving range. Pricing will start at $105,595 before options are factored in. Several months later, GMC will release an EV2X variant with up to 625 horsepower, about the same amount of driving range, and an $89,995 price tag before incentives.

2022 Hummer EV Edition 1 pickups ready to go to customers

It's official: Two years after GM announced the electric GMC Hummer pickup, the first couple dozen units have left the line at the GM Factory Zero Detroit-Hamtramck Assembly Center, according to GM president Mark Reuss. In an interview with CNBC to celebrate the milestone, Reuss said 17 Hummer EVs are ready for delivery to customers. This makes the Hummer the first of GM's new Ultium-based EVs to leave the factory, and the second electric pickup on the market after the Rivian R1T. The first 1,200 Hummer EVs made will be Edition 1 models, all of which are Interstellar White outside with Lunar Horizon interiors and bronze badging. Each of the $112,595 pickups is powered by three Ultium motors producing a GM-estimated 1,000 horsepower and 11,500 pound-feet of torque, loaded with features like height-adjusting adaptive suspension, skid rails and rock sliders, 35-inch tires, the diagonal-driving CrabWalk, the launch control system Watts to Freedom that unlocks a three-second sprint to 60 miles per hour, and Super Cruise. Range is a GM-estimated 329 miles when the 200-kWh battery is fully charged. As these filter out to eager owners, GM is prepping the next four phases of the Hummer rollout. About a year from now, in autumn of 2022, Factory Zero will begin production of the first widely available Hummer, the EV3X pickup that starts at $99,995 before destination. Three Ultium motors will provide an estimated 800 horsepower and 9,500 pound-feet of torque to a range estimated beyond 300 miles. Spring of 2023 is expected to deliver the Hummer EV2X pickup at an MSRP of $89,995, utilizing two motors producing a total 625 hp and 7,400 lb-ft over a range also estimated to go beyond 300 miles. Around the same time, the first units of the $105,595 Hummer SUV Edition 1 are planned to head down lines at Factory Zero. Finally, in the spring of 2024, the entry-level $79,995 Hummer EV2 pickup and its two-motor powertrain should arrive, making the same output as the EV2X, but only good for a range of around 250 miles. That won't be all we see from Factory Zero, either. GM invested $2.2 billion in the Detroit-Hamtramck plant that once built bread-and-butter GM fare like the Chevrolet Impala, Buick LaCrosse, and Oldsmobile Toronado in order to turn the facility into its first EV base of manufacturing operations for Ultium products. The battery-electric Chevrolet Silverado and GMC Sierra pickups will be built there, as will the Cruise Origin robotaxi.

GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.
