General Motors recently released a new teaser video for the GMC Hummer EV, announcing that the debut will take place in the fall, while also showing off the fresh battery-powered utility vehicle with a series of quick shots and hints of future features. Included in the video was a set of shadowy silhouettes for both the upcoming Hummer EV SUT (Sport Utility Truck) and the Hummer EV SUV, both of which included outlines of the wheels and tires. While GM didn’t include any specs, we wanted to do a brief thought experiment using the teaser to investigate the new vehicles’ exterior dimensions.
Here’s the experiment – by taking images from the teaser and importing them into a CAD program, we can accurately scale certain aspects of the image. So, if we assume something like the tire diameter, we can then derive other measurements, such as the overall length and the wheelbase.
Naturally, we should preface this by saying that our assumptions could be off-base here, and that this thought experiment is just really just for fun.
That said, we’re assuming that the tires pictured in the teaser images are 35 inches in diameter. From there, we can calculate a 137.4-inch wheelbase and 217.6-inch overall length for the GMC Hummer EV SUT, as well as a 130.3-inch wheelbase and 194.1-inch overall length for the GMC Hummer EV SUV.
Assuming these dimensions are at least in the right ballpark, there are a few conclusions we can draw. First, the new GMC Hummer EV is big, but overall length is still much smaller than the the full-size GMC Yukon, backing our previous speculation that the SUV model is more of a midsize entry.
For reference, the all-new 2021 GMC Yukon measures in with a 120.9-inch wheelbase and 210-inch overall length, while the extended-length 2021 GMC Yukon XL gets a 134.1-inch wheelbase and 225.2-inch overall length.
We can also compare the numbers to other relevant entries outside the GM portfolio, such as the 2020 Land Rover Defender, which gets an overall length of 180.4 to 197.6 inches, while the wheelbase is 101.9 inches to 119 inches. The 2021 Ford Bronco four-door gets an overall length measuring between 189.4 inches and 190.5 inches, and a wheelbase of 116.1 inches. Finally, the Jeep Wrangler Unlimited has 188.4 inches for overall length, and 118.4 inches for the wheelbase, while the Jeep Gladiator gets a 218-inch overall length and 137.3 inches for the wheelbase.
|Vehicle||Overall Length (in.)||Wheelbase (in.)|
|GMC Hummer EV SUT (estimate)||217.6||137.4|
|GMC Hummer EV SUV (estimate)||194.1||130.3|
|2021 GMC Yukon||210||120.9|
|2021 GMC Yukon XL||225.2||134.1|
|2020 Land Rover Defender||180.4 to 197.6||101.9 to 119|
|2021 Ford Bronco four-door||189.4 to 190.5||116.1|
|Jeep Wrangler Unlimited||188.4||118.4|
Again, our numbers for the new GMC Hummer EV are based on a few as-of-yet unconfirmed assumptions, so take them with an appropriately sized grain of salt. That said, if the numbers do turn out to be accurate, how would they shape your opinion of the new Hummer EV?
