Should anyone be shocked?
The 2022 GMC Hummer EV Edition 1 is a heavy thing. Weight has always been the enemy of vehicles' power and efficiency. EVs are no different due to their heavy battery packs. But the reborn Hummer takes weight to another level and its efficiency suffers for this.
Car and Driver has uncovered an official EPA document stating the Hummer's weight and efficiency range. Without further ado, the fully-loaded, 2022 Hummer Edition 1 (priced at $110,295) has a curb weight of 9,063 pounds (the battery alone weighs 2,923 pounds!) and a 47 MPGe combined rating. Drivers will achieve 51 MPGe city and 43 MPGe highway. It will go up to an EPA-rated 329 miles on a single charge using 212.7 kWh of electricity.
Now, here's where some (but definitely not all) Hummer Edition 1 buyers might get a bit upset. When it launched over a year ago, GM claimed it'd go up to 350 miles on a single charge. Official testing confirms otherwise. Should we be surprised? No. Despite designers' and engineers' best efforts to improve things like aerodynamics, the big Hummer can't defy the laws of physics.
Sure, it does have over 1,000 horsepower, but the power-to-weight ratio certainly matters. GMC did confirm it will not be displaying the Hummer's MPGe figures on the window sticker because it's not required to do so for any model with a gross vehicle weight rating (GVWR) in excess of 8,500 pounds.
Automakers can display MPGe if they so choose, which is exactly what Rivian is doing with the R1T. It has a GVWR of just slightly over 8,500 pounds. For comparison's sake, Ford estimates its 6,500-pound F-150 Lightning will achieve around 300 miles of range when equipped with the optional 131-kWh extended-range battery. The Rivian R1T has a claimed 400-mile range but only when equipped with the Max Pack. It also earned a 70 MPGe EPA rating.
It's probably fair to say that those buying a Hummer Edition 1, or any Hummer EV trim for that matter, probably aren't too interested in maximum efficiency. No, they want that 1,000 hp, cool features like Crab Walk, bragging rights, and perhaps the ability to pop a wheelie or two.
