GMC SUV Gas Mileage Chart

Which GMC SUV Gets the Best Gas Mileage?

The electric Hummer gets the best GMC SUV MPG by a wide margin—but if you’re not interested in going electric or in buying a large SUV, then you’re probably more concerned about which GMC SUV gets the best gas mileage among those with combustion engines. Whatever your preference, here’s what Southgate and Brownstown-area drivers should keep in mind:

  • In general, smaller vehicles earn better mileage because it takes less power to move them from point A to point B.
  • Looking for the most efficient Terrain? GMC SUV MPG for this and any other model will be best with a front-wheel drive configuration. FWD vehicles earn better MPG because they use less power by restricting output to the front axle, rather than powering both axles.
  • The Terrain comes standard with a 1.5 L turbo 4-cylinder engine mated to an automatic 9-speed transmission. It earns up to 25 city/30 highway/27 combined MPG in its FWD configuration; AWD models make 25 city/28 highway/26 combined MPG.
  • Don’t let the green powertrain fool you: the GMC Hummer SUV EV is a powerhouse to be reckoned with. It generates an eye-popping maximum 830 hp, up to 11,500 lb-ft of available torque, and it can rocket its large frame from 0-60 MPH in only 3.5 seconds.
  • The GMC Hummer EV SUV’s Ultium Battery Platform uses vertically-stacked cells that increase the density of stored power. The result? An electric range of more than 300 miles on a single charge.
