Fuel economy at a glance

These are the EPA's official ratings for the 2025 GMC Hummer EV SUV MT Tires 3X. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

Combined MPG 48 MPG
City MPG 53 MPG
Highway MPG 43 MPG

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for electricity, which is $0.15/kilowatt-hour. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPGe and the reference electricity price stay constant, only the annual mileage changes. Charging at home rather than at a public DC fast charger usually lowers the real cost below the EPA's published figure.

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $800
Average driver, 15,000 miles per year $1,600
Heavy driver, 25,000 miles per year $2,667

Specifications

The 2025 GMC Hummer EV SUV MT Tires 3X is a fully electric vehicle. It is powered by 195, 195 and 215 kw acpm. The EPA rates its driving range at 289 miles.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

  • Does the 2025 GMC Hummer EV SUV MT Tires 3X use gasoline?
    No. The 2025 GMC Hummer EV SUV MT Tires 3X is fully electric and runs on grid electricity. The MPGe figure on this page converts electricity use into a gasoline-equivalent so you can compare it directly to a regular car.
  • How much CO₂ does the 2025 GMC Hummer EV SUV MT Tires 3X emit?
    The 2025 GMC Hummer EV SUV MT Tires 3X produces zero tailpipe emissions because it runs entirely on electricity. The full carbon footprint of charging it depends on how the electricity on your local grid is generated, which varies a lot from one state to another.
  • What is the difference between the city and highway MPG of the 2025 GMC Hummer EV SUV MT Tires 3X?
    City driving returns 53 MPG and highway driving returns 43 MPG. A flat (or city-better) split is the signature of a hybrid or electric drivetrain, where regenerative braking recovers energy that would otherwise be lost in stop-start city traffic.

    The 2025 GMC Hummer EV SUV MT Tires 3X uses 195, 195 and 215 kW ACPM. Electric motors do not have a displacement or cylinder count the way a combustion engine does, so EPA reporting focuses on the motor type and battery system instead.
  • What transmission and drivetrain does the 2025 GMC Hummer EV SUV MT Tires 3X have?
    The 2025 GMC Hummer EV SUV MT Tires 3X comes with a automatic (a1) transmission and all-wheel drive. All-wheel-drive variants typically read 1 to 3 MPG lower than the front-wheel-drive equivalent of the same engine, since the extra hardware adds weight and parasitic loss.
  • How does the 2025 GMC Hummer EV SUV MT Tires 3X compare to the best car in its class?
    The most efficient car in the Standard Sport Utility Vehicle 4WD class for the 2025 model year is the Lucid Gravity GT w/20F21R wheels (2R) at 108 combined MPG. The GMC Hummer EV SUV MT Tires 3X returns 48 MPG, a gap of 60 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
