The 2024 GMC Hummer EV Pickup 2M20 achieves a combined MPG equivalent of 52. This figure might seem strange for a vehicle that looks like its gas-guzzling ancestor, but that’s the benefit of an all-electric powertrain. This isn’t a machine that prioritizes efficiency above all else; it is a statement, an off-road dominator, and a technological showcase. The targeted consumer isn’t focused on squeezing every last mile from each electron. They’re drawn to its unmatched presence, cutting-edge technology, and the ability to conquer almost any terrain in near silence. The efficiency is a bonus and a demonstration of potential, rather than the primary reason for buying it.

City and highway performance

The difference between city and highway MPG reveals an interesting characteristic of the Hummer EV. Around town, it manages 58 MPGe, showing the benefits of regenerative braking and stop-and-go driving conditions that favor electric powertrains. On the open road, at higher, constant speeds, the MPGe drops to 46. This difference is typical for EVs, as they don’t benefit as much from regenerative braking at sustained speeds, and aerodynamic drag becomes a factor. The upright profile of the Hummer EV is far from aerodynamically slippery.

Annual fuel cost

According to EPA estimates, the annual fuel cost for the 2024 GMC Hummer EV Pickup 2M20 is $1,450. This figure is based on driving 15,000 miles per year, using a national average price for electricity. Your personal electricity costs and driving habits will influence your actual expenditure. Those with access to cheaper off-peak charging or solar power will spend considerably less, while those who drive more than 15,000 miles annually will see a higher cost.

Real-world expectations

While the EPA estimates provide a valuable baseline, real-world fuel economy can vary based on several factors. Aggressive driving, frequent use of “Watts to Freedom” mode, towing, carrying heavy loads, and operating in extreme temperatures can negatively impact efficiency. Expect to see a dip in range and MPGe if you frequently exploit the Hummer EV’s acceleration and off-road capabilities. Conversely, conservative driving and a focus on maximizing regenerative braking can help you achieve figures closer to, or even exceeding, the EPA estimates. The massive 200+ kWh battery pack provides a substantial buffer, making range anxiety less of a concern for typical daily driving.

How it compares

Direct comparisons to other all-electric trucks reveal where the Hummer EV fits. The Rivian R1T Quad-Motor, for example, achieves an EPA-estimated 74 MPGe combined. The Ford F-150 Lightning Extended Range comes in at 70 MPGe combined. While these competitors have higher MPGe figures, the Hummer EV offers a unique blend of extreme off-road capability, imposing presence, and innovative features that appeal to a specific buyer. Someone considering all Gmc fuel economy data alongside other trucks is likely to accept the trade-off in efficiency for the Hummer EV’s unique attributes. It is also important to consider that those focused on energy savings may search for HUMMER MPG across all years. This comparison highlights where the Hummer EV sits within the emerging electric truck market: not necessarily the most efficient, but undeniably one of the most capable and attention-grabbing options.

Tips to maximize efficiency

Use regenerative braking. The Hummer EV features multiple regenerative braking modes, including one-pedal driving. Experiment with these settings to find the level that best suits your driving style and maximizes energy recovery. Anticipate traffic and ease off the accelerator early to allow the regenerative braking system to slow the vehicle smoothly and capture energy.

Precondition the battery. During cold weather, use the vehicle’s app or infotainment system to precondition the battery while it’s plugged in. This warms the battery to its optimal operating temperature, improving efficiency and range. In hot weather, pre-cooling the cabin can reduce the energy required for air conditioning during your drive.

Moderate your speed. As with any vehicle, excessive speed significantly reduces efficiency. Maintaining a steady speed within the posted limits, especially on the highway, can noticeably improve your MPGe and extend your driving range. Avoid constantly accelerating and decelerating aggressively.

Carefully consider your tire choice. While the Hummer EV comes with off-road-oriented tires which dramatically improve its performance, they can increase rolling resistance and reduce efficiency on paved roads. If you primarily drive on the street, consider switching to a less aggressive tire with a lower rolling resistance to boost your MPGe.
