GMC Hummer EV SUV vs. Older Hummer Models: Dimensional Comparison

General Motors recently pulled the sheets on the GMC Hummer EV SUV, adding a new body style to the all-electric Hummer lineup. Although the new Hummer EV takes inspiration from the previous-generation Hummer models when it comes to styling and off-roading prowess, there are some pretty sizable dimensional differences between the various generations. Now, we’re taking a closer look at these differences in the following GM Authority Dimensional Comparison.

Exterior Dimensions

Let’s start outside, where we find the GMC Hummer EV SUV is closest to the Hummer H1 with regard to sizing. Interestingly, the Hummer H1 has the longest wheelbase in this comparison, measuring in at 130 inches, as compared to the 126.7-inch wheelbase of the of the Hummer EV SUV. Even so, the Hummer EV SUV has a longer overall length (196.8 inches), taller overall height (80.9 inches), and wider front and rear tracks (73.3 inches).

That said, overall width and ground clearance are identical between the Hummer EV and H1, measured at 86.5 inches and 16 inches, respectively.

  2. ahh i dont know if this will fit in my garage. which is kindof the point with an electric vehicle (i guess an extension cord it is). I know elon musk was saying for the cybertruck that fitting in a standard garage was an important point, granted it seems like they only want to sell 10k of these a year or something compared to the hundreds of thousands of cybertrucks.

    Hey GM, how about a garage parking assist feature, where i could get out of the hummer and via the key fob have it slowly park itself. 18 cameras gotta be good for something. the genesis has this feature.

  4. Wow! The thing is HUGE.
    I thought it was going to be more H2 sized, but it’s bigger than the old H1/HUMVEE. Damn!

    I wonder if the huge size will crimp it’s sales.
