The GMC Hummer EV Pickup and GMC Hummer EV SUV recently for the very first time emerged on the EPA’s website, showing range and efficiency ratings.<\/p>\n
That’s an interesting thing because previously General Motors was estimating the pickup’s driving range on its own. The company explained to us at the time that the initial 2022 GMC Hummer EV Pickup would not get an EPA rating because it was classified as a heavy-duty pickup. As we understand, above a certain weight level, there are different rules, just like with safety\/crash test requirements.<\/p>\n
But recently, we surprisingly come across a 2024 GMC Hummer EV Pickup and GMC Hummer EV SUV on the EPA’s website. Both vehicles have two ratings – one with standard 22-inch wheels and one with 18-inch wheels and 35-inch Mud-Terrain (MT) tires.<\/p>\n
EPA Combined range:<\/p>\n
The EPA Combined range numbers match the ones that GMC published for the GMC Hummer EV SUV Edition 1 and 3X trims, equipped with a smaller battery – 20 modules (compared to 24 in Edition 1 of the Pickup). This would suggest that the versions with 20 battery modules are light enough to be included in EPA ratings.<\/p>\n
The 3X trim comes standard with 20 battery modules (24 battery modules are optional only in the case of the Pickup).<\/p>\n
<\/p>\n
The double-stacked battery pack in the GMC Hummer EV Pickup 3X (24 modules) allows it to achieve a higher range (GM-estimated):<\/p>\n
GMC does not list the exact battery capacity on its website, but we heard that the 24 modules translate into a level of 205 kilowatt-hours, while the 20 modules is roughly 170 kWh.<\/p>\n

2024 GMC Hummer EV Edition 1<\/p>\n
The GMC Hummer EVs are the two largest and heaviest all-electric vehicles available on the market (excluding trucks and buses), which combined with a three-motor powertrain, are strong enough to accelerate from 0 to 60 mph in just 3-3.5 seconds. That must result in significant energy consumption. And that’s exactly what we see in the EPA rating.<\/p>\n
Energy consumption, including charging losses, of the Pickup and SUV 3X (20 battery modules) with 22-inch wheels is estimated at 53 MPGe: 636 watt-hours per mile.<\/p>\n
If one selects 18-inch wheels and 35-inch Mud-Terrain tires, then the result is even worse – 50 MPGe: 674 Wh\/mi.<\/p>\n
Because of the boxy shape (not too good for aerodynamics), the EPA Highway range might be around a tenth lower than the EPA Combined value.<\/p>\n
