2024 GMC Hummer EV SUV vs. Tesla Model X, Rivian R1S Specs Comparison


If you want a big, practical EV SUV with a range of around 300 miles, you go for the Tesla Model X, right? Well, perhaps not anymore. There is a new contender with an old name entering the ring, and it’s the new GMC Hummer. The GMC Hummer EV SUV is, as you might have guessed, the bed-less, enclosed-body counterpart to the new Hummer EV pickup truck. And while it won’t hit dealerships until early 2023 as a 2024 model-year offering, we figured it’d be worthwhile to see how it stacks up with the default choice for EV SUV buyers, the Tesla Model X.

But wait! What about the upcoming Rivian R1S? That’s right, Rivian, too, has an SUV version of its R1T EV pickup truck which promises to be just as capable and luxurious as the Tesla and the Hummer.

Oh yes people, the electric luxury SUV wars are upon us, and we’re more than intrigued as to which of these three will come out on top when we finally get behind the wheel. But, for right now, each SUV’s on-paper specs will have to suffice. For the sake of this comparison, we’re going to stick primarily with top-of-the-line, most powerful trims to keep things simple and compare maximum capabilities. After all, if you’re thinking about the future of cars, the phrase latest and greatest will likely be at the front of your mind, anyway.

Hummer EV SUV vs. Tesla Model X, Rivian R1S: Range, Power, and Torque

Let’s start with the newest kid on this block. The Hummer EV SUV will come in three trim levels, starting with the EV2X and moving up to EV3X and the Edition 1. That top-dog Edition 1 lands first, with three electric motors (two on the rear axle and one on the front), a claimed range of 300 miles on a single charge, and mountains of power and torque. GMC claims the SUV has 830 hp and 11,500 lb-ft of torque (that figure is fudged, in that it is measured at the wheels—an uncommon method). We did a little number crunching and gather the torque figure is a much less mind-boggling 1,045 lb-ft—still more than enough, though. Lesser two-motor Hummers make do with 625 hp and 617 lb-ft, along with 250 miles of range.

The Rivian R1S is a Tesla challenger we’ve known about for a while, and it’s inching ever closer to production this year. The top-spec Rivian SUVs will carry a 180-kWh battery that’ll be good for “400+” miles of range, per the manufacturer. Power is sent through four individual electric motors—one at each wheel—and total output is rated at 900 hp for R1S models with the largest “MegaPack” battery. Max torque is rated at 800 lb-ft, and even though that might not trouble the Hummer, it’s still enough to shoot the R1S from 0 to 60 mph in a claimed 3.0 seconds flat.

Tesla has had a long-standing advantage over the competition, and the recently refreshed Model X range now features a Plaid model with some truly Ludicrous performance potential. The tri-motor Model X Plaid was unveiled earlier this year and makes 1,020 hp. Tesla doesn’t really talk torque, but it’s safe to assume it’s not far off the numbers both the Rivian and Hummer make. The tri-motor Model X Plaid also has a max claimed range of 340 miles on a single charge, putting it right in the middle of the R1S and Hummer EV SUV. The regular, dual-motor Model X Long Range serves up 360 miles of range, per Tesla.

Hummer EV SUV vs. Tesla Model X, Rivian R1S: Off-Road Ability

One of these EVs is not like the others, and the odd SUV out is the Model X. If you want something with any kind of off-road prowess from Tesla, you’ll likely have to wait for the Cybertruck electric pickup—deliveries of which are slated for later this year, but likely won’t come for some time. With its lack of ground clearance—compared to the Hummer and Rivian—and other off-road specific tech, or even so much as an off-road tire option, the Model X can’t compete when the going gets rocky. Or sandy. Or muddy. It’s a street machine.

The Rivian, for its part, promises superb off-road capability thanks to individually controlled wheels (each one driven by its own dedicated electric motor) and standard air suspension with ground clearance ranging from 8.1 inches to a whopping 14.4 inches. That should give the R1S a huge advantage over conventional off-roaders like the Jeep Wrangler. Approach, departure, and breakover angles for the R1S are 34, 30, and 28.9 degrees, respectively, and it should be able to scramble over obstacles with the best.

Perhaps the most off-road-ready EV of them all is the Hummer. The Hummer has breakover and departure angles of 34.4 and 45.6 degrees, respectively, offers approximately 13 inches of total suspension travel, has four-wheel steering (which is taken advantage of by CrabWalk Mode to help get you out of tight spots), and can even be ordered with 37-inch tires from the dealer. There’s an onboard inverter for powering off-road accessories, and the GMC can be had with an Extreme Off Road pack that includes smaller 18-inch wheels with chunkier all-terrain tires, underbody armor, rock sliders, a front eLocker differential, and virtual rear lockers, as well as heavy-duty half shafts.

Clearly, GM thinks its customers will want to take their Hummers off-road, and for now, it looks like the advantage lies in the Hummer’s corner.

Hummer EV SUV vs. Tesla Model X, Rivian R1S: Sizing Them Up

As every SUV listed here is electric, there are certain similarities all three share. For example, every one of the SUVs offers a”frunk,” or front trunk,  that takes advantage of the space where an engine would go in a typical gas-fed vehicle. A flat floor is common to all three, as well, as is seating for at least five people.

However, the GMC Hummer, Rivian R1S, and Tesla Model X deviate dimensionally. As you might have guessed, the Hummer is the biggest, maintaining the original Hummer models’ penchant for sheer size. The Hummer SUV has a wheelbase of 126.7 inches and is 86.7 inches wide and 206.7 inches long (with the spare tires attached to the swing-out tailgate).

The Rivian is much smaller. Its wheelbase is 121.1 inches, while the body is 79 inches wide and 200.7 inches long. It’s not exactly a compact SUV, but next to the Hummer, the R1S would probably look small. The Model X is even smaller, at 78.7 inches wide, 198.3 inches long, with a 116.7-inch-long wheelbase.

Hummer EV SUV vs. Tesla Model X, Rivian R1S: Money Matters

The 2024 GMC Hummer EV SUV Edition 1 is the first version of the Hummer SUV buyers will be able to get their hands on, and it starts at $105,595. If you want the aforementioned Extreme Off-Road pack you’ll need to pony up another $5,000. (Lesser Hummers will start at just under $80,000.) Tesla’s Model X Plaid starts at $118,490 and will be available much sooner than the Hummer or the Rivian. According to Tesla’s site, if you order a Model X Plaid today, you should get it between May and June.

Rivian’s R1S is closer to production than the Hummer and is also the least expensive of this trio. Top Spec Rivian SUVs will start at $77,500 with the Adventure Package. Without that, the price drops to $70,000, making it the bargain of this battery-powered bunch.
