Car and Driver review of the 2024 GMC Hummer EV

The 2024 GMC Hummer EV is the brand’s electric supertruck. What makes the nearly five-ton EV pickup super? It has a host of hardcore hardware and up to 1000 horsepower. That output applies to the tri-motor all-wheel-drive configuration that also has a WTF mode—short for Watts to Freedom. The one we tested hit 60 mph in 3.3 seconds, insanely quick for something this size. Its lengthy emergency stopping distance was less impressive. GMC touts a maximum driving range of 381 miles; the 570-hp dual-motor AWD model has a 311-mile estimate. Range is reduced with the Extreme Off-Road package that adds 35-inch mud-terrain tires, beefier axles, and extra underbody armor. All Hummer EV pickups have a five-foot box, a height-adjustable air suspension, rear-axle steering, and Super Cruise (GM’s hands-free driving tech). If you don’t need a pickup truck bed, there’s also an SUV version, which we review separately. While its interior isn’t on par with its approximately six-digit price tag, there’s nothing else on the road or the trails quite like the 2024 Hummer EV pickup truck.

 What’s New for 2024?

Sometime this year GMC is expected to introduce a more affordable version of the Hummer pickup, which will likely still cost north of $85,000. While we await details about that model, the top-spec EV3X has higher range estimates than the previous model year thanks to a newly available 24-module battery pack. GMC claims the $9995 option increases the truck’s peak range per charge to 381 miles.

The price of the 2024 GMC Hummer EV Pickup starts at $98,845 and goes up to $106,945 depending on the trim and options.

 The Hummer EV3X costs $8100 more than the EV2X, but we’d spend that to almost double the horsepower as well as the Watts to Freedom launch-control mode that’s sure to impress our friends by enabling rocketship-like takeoffs. The EPA estimates that tri-motor models with the standard battery and 22-inch wheels have a 314-mile range, but a new optional extended-range battery unlocks an estimated range of 381 miles. We’d pass on the bigger pack and instead choose the Extreme Off-Road package. That drops the range estimate to 298 miles but adds beadlock-capable 35-inch mud-terrain tires, beefier axles, locking differentials, added underbody armor, and more camera angles. The separate Off-Road Readiness package adds a full-size spare tire that matches the other wheels and a vertical bed-mounted carrier. To truly enjoy our outdoor adventures, we’d also choose the available removable roof panels. 

The Hummer EV currently offers either two or three electric motors. Both configurations offer all-wheel drive; the dual-motor setup has 570 hp and the tri-motor version has 1000 hp. The Hummer EV Edition 1 we tested had the latter, and it rocketed to 60 mph in 3.3 seconds thanks to its Watts to Freedom (WTF) launch control driving mode. That makes it one of the quickest pickups we’ve ever tested. While we were wowed by its acceleration, we were disappointed by its braking performance. Slowing the massive machine to a stop from 70 mph took an extra-long 211 feet, and repeated runs resulted in noticeable brake fade. Yikes. Maneuverability at low speeds is better than expected, a direct result of the rear-wheel-steering system, but once you’re up and running the Hummer EV is as unwieldy to drive as other lifted brodozers.

The Hummer EV pickup’s maximum towing capacity is a stout 12,000 pounds, but that requires going with the 570-hp dual-motor powertrain. That exceeds the ratings for the Ford F-150 Lightning and the Rivian R1T, which are rated at up to 10,000 and 11,000 pounds, respectively. However, Hummers with three motors have a towing capacity between 7500 and 8500 pounds. During our towing test pulling a 6100-pound double-axle camping trailer, the range of our Hummer EV dropped to just 140 miles at 70 mph.

The Hummer EV is available with two battery sizes. The standard 20-module pack provides an EPA-estimated driving range of 311 miles for the EV2X and 314 miles for the EV3X. The latter can be equipped with a 24-module battery that GMC claims provides up to 381 miles of range. Opting for the Extreme Off-Road package reduces that estimate to 359 miles. The Hummer EV Edition 1 we tested on our 75-mph highway route traveled 290 miles on a full charge. While it reached a peak charging rate of 287 kilowatts while connected to a DC fast-charger, it only averaged 98 kW, and it took more than two hours to charge its battery from 10 to 90 percent. GMC claims the Hummer EV pickup will add 100 miles of range in just 10 minutes; we needed about twice as long.

The Hummer truck’s massive weight is the enemy of efficiency. The three-motor model with its standard 22-inch wheels has an EPA-rated 58 MPGe combined. Compare that with the most powerful version of the F-150 Lightning and R1T (both fitted with 22-inch wheels) that earn 66 and 68 MPGe, respectively.

Even though Hummers of yesteryear were mainly SUVs, the Hummer EV takes the form of a crew-cab pickup truck with a five-foot-long bed. Interior materials could be of higher quality considering the Hummer’s price tag and its cabin isn’t as spacious as GMC Sierra 1500 crew cabs. But the interior can be opened to the elements via optional removable roof panels that reintroduce a T-top–esque design popular in GM sports and muscle cars in the 1970s and 1980s. When in place, the transparent panels are akin to a normal panoramic glass sunroof, but lifting them off and stowing them in the Hummer’s front trunk gives the truck a convertible vibe similar to that of the Jeep Gladiator. Inside, several moon-inspired touches—such as a moon-boot footprint on the dead pedal and speaker grilles that show the Sea of Tranquility—serve as not-so-subtle reminders of GM’s connection to NASA astronauts and the electrically powered Apollo 15 lunar rover that the company helped engineer.

A large 13.4-inch display serves as the infotainment screen, and there’s a 12.3-inch digital instrument panel as well. GMC has contracted Epic Games—maker of the wildly popular Fortnite video game—to create the graphics for the Hummer EV’s infotainment interface. The high-resolution screen and advanced graphics look great, but we noticed some pronounced lag that suggests the system doesn’t have quite the processing power it needs to keep up with the software’s capabilities. A host of connectivity features are standard, including wireless Apple CarPlay and Android Auto, a Wi-Fi hotspot, and GM’s OnStar telematics system.

GM’s Super Cruise hands-free driving mode is a standard feature and we’ve found it works quite nicely. Less advanced features such as lane-keeping assist and blind-spot monitoring are also included. For more information about the Hummer EV’s crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

• Standard automated emergency braking with pedestrian detection
• Standard lane-departure warning and lane-keeping assist
• Standard adaptive cruise control with hands-free driving mode

The Hummer EV comes with a similar warranty to other General Motors products, which means three-year/36,000-mile bumper-to-bumper coverage and five-year/60,000-mile powertrain coverage.

• Limited warranty covers three years or 36,000 miles
• Powertrain warranty covers five years or 60,000 miles
• Hybrid components are covered for eight years or 100,000 miles
• Complimentary maintenance is covered for the first visit
