The GMC Hummer EV SUV’s EPA-rated efficiency figures have been disclosed, showcasing its unique efficiency and power balance.
EPA-rated efficiency is 59/48/53 MPGe for city/highway/combined, slightly higher than previous estimates.
Despite its impressive power, the Hummer EV’s energy efficiency falls behind rivals like Ford F-150 Lightning and Rivian R1S.
The EPA-rated fuel efficiency details for the GMC Hummer EV SUV are now available, shedding light on its efficiency performance. The EV achieves an EPA-rated efficiency of 59/48/53 MPGe for city/highway/combined driving with its 22-inch wheels, surpassing the earlier leaked 47 MPGe combined rating for the Hummer EV Edition 1. However, the efficiency remains relatively lower in comparison. These figures are specific to the Hummer EV equipped with larger wheels.
The Hummer EV with 18-inch wheels and 35-inch mud-terrain tires achieves an EPA-rated efficiency of 55/45/50 MPGe. Unsurprisingly, the Hummer EV SUV and Pickup models share similar efficiency ratings. This sets the Hummer EV apart from rivals like the Ford F-150 Lightning and Rivian R1S, which boast a combined EPA rating of 68 MPGe. This highlights the Hummer EV’s distinct energy consumption, showcasing it as notably less efficient than its counterparts.
The substantial weight of the Hummer EV significantly contributes to its lower efficiency. This weight is largely due to the sizable battery pack, weighing over 2,800 lbs, which is notably heavier than an entire Mazda Miata (MX-5).
Further analysis of the EPA data reveals that the Hummer EV SUV can cover around 314 miles per charge, with this range decreasing slightly to 298 miles when equipped with the 35-inch mud-terrain tires. In comparison, the 3X trims, featuring the optional 24-module battery pack, are expected to offer a range of 381 miles for the Hummer EV and 359 miles for the 2024 Hummer EV with MT tires.
Despite its relatively lower efficiency, the Hummer EV has its strengths, including the ability to accommodate a robust 1,000-horsepower tri-motor powertrain. This powertrain enables the Hummer EV to accelerate from 0 to 60 mph in approximately three seconds, an impressive feat considering the vehicle’s weight and aerodynamic characteristics.
While its efficiency might not be class-leading, its exceptional power and performance attributes offer an appealing option for consumers prioritizing these aspects over strict energy efficiency.
