350 Miles on a Single Charge: Inside the Hummer EV SUV’s Revolutionary Battery Technology
Now there are more Hummer variants available, but the first run of 2023 GMC Hummer EVs featured only one specification: the pickup truck in Edition 1 with all the off-road upgrades. The most significant of these upgrades, which affected the electric range, were the 18-inch wheels with mud-terrain tires. This configuration had a range rating of 329 miles.
The pickup truck is now available in a 3X trim, which comes with more efficient all-terrain tires mounted on 22-inch wheels. Additionally, there is now a 2024 Hummer EV SUV available in both trims and with both types of tires, as well as a smaller battery pack.
Recently, official range estimates have been released for these new configurations. The tires play a crucial role in determining the SUV's range, with the Edition 1 and 3X versions, both equipped with all-terrain tires, capable of achieving 314 miles of range. However, this is less than even the mud-terrain-equipped pickup truck. The SUV's shorter length means it has fewer battery cells and less capacity, with about 170 kWh compared to the truck's 200+. Opting for the Extreme Off-Road Package, which includes more aggressive tires, decreases the range to 298 miles.
GMC has highlighted that the Hummer EV truck can achieve a solid range boost up to 355 miles without the off-road package, just like the SUVs. According to GMC, all-terrain-equipped trucks have the potential benefit of having a suspension tuned for better on-road handling. The truck gains towing capacity from the use of regular all-terrain tires. Compared to the models with the off-road package, the truck equipped with regular all-terrain tires can tow an extra 1,000 pounds, with a capacity of 8,500 pounds.
