The 2024 GMC Hummer EV SUV has a combined fuel economy rating of 53 MPG, but understanding that number is important. This isn’t your average compact crossover sipping gasoline efficiently. This is an electric super-truck, a statement piece with off-road capability and eye-catching design, delivering 53 MPGe (miles per gallon equivalent), a measure of electrical efficiency in place of gasoline consumption.

City and highway performance

The EPA estimates translate to 59 MPGe in the city and 48 MPGe on the highway. City driving tends to favor electric vehicles because of regenerative braking, which recovers energy during deceleration and stop-and-go traffic. The Hummer EV SUV takes advantage of this, showing higher efficiency in urban environments. Highway driving, with higher sustained speeds, typically results in slightly lower MPGe as aerodynamics and rolling resistance affect efficiency more. However, 48 MPGe on the highway is still impressive considering the Hummer EV SUV’s size and weight.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,450 for the 2024 GMC Hummer EV SUV. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average electricity price. Remember that your actual fuel cost will vary depending on your driving habits, electricity prices in your area, and how frequently you charge at home or at public stations.

Real-world expectations

Owners of the Hummer EV SUV aren’t primarily motivated by squeezing every last mile out of a kilowatt. They seek a unique vehicle that blends electric technology with off-road capability and distinctive styling. Range anxiety is typically less of a concern for this driver than it would be for someone solely focused on maximizing efficiency. They understand that the Hummer EV SUV’s size and capabilities mean that real-world range and efficiency can fluctuate significantly based on driving conditions. For example, aggressive off-roading or towing will diminish the vehicle’s range considerably, potentially leading to more frequent charging stops.

How it compares

Comparisons to other electric SUVs are helpful for context. The Tesla Model X, for instance, achieves a combined 102 MPGe in Long Range trim. The Rivian R1S boasts 73 MPGe combined. The Cadillac Lyriq with RWD comes in at 95 MPGe combined. These SUVs prioritize efficiency to a greater extent than the Hummer EV SUV does, which focuses more on power, off-road capability, and visual impact. Consider the Hummer EV SUV compared against traditional off-road vehicles as well, where there is simply no comparison. Understanding these trade-offs is essential for prospective buyers. Take a look at all Gmc fuel economy data to get a sense of their overall electric efficiency.

Tips to maximize efficiency

Use regenerative braking modes effectively. The Hummer EV SUV offers different levels of regenerative braking, including a one-pedal driving mode. Maximize regeneration to recapture energy during deceleration and reduce reliance on the friction brakes, thus extending your range.

Precondition the battery before driving, especially in cold weather. Preconditioning warms the battery while plugged in, so the battery doesn’t have to work as hard to reach its optimal operating temperature on the road. This can help maintain range, especially in colder climates.

Monitor your tire pressure regularly. Maintaining the correct tire pressure reduces rolling resistance, which can improve efficiency. Refer to the sticker on your driver’s side doorjamb for the recommended tire pressure.

Minimize aggressive driving. Avoid sudden acceleration and hard braking, as these actions consume more energy. Smooth and consistent driving is key to maximizing efficiency in any electric vehicle, including the Hummer EV SUV. Remember to review HUMMER MPG across all years to get a feel for the vehicle’s overall efficiency.

Consider adjusting charging habits. Time-of-use electricity rates can fluctuate based on demand. If your utility offers lower rates during off-peak hours (usually overnight), schedule your Hummer EV SUV to charge during these times. Not only can this save money, but it can also help reduce strain on the power grid.
