2027 Terrain Driving Range & Fuel Tank Capacity
We provided the driving range you can expect from the GMC Terrain in our visual above – and the fuel tank capacity – but we'll review the details for clarity.
To be clear, the new 2027 GMC Terrain can be equipped with one of two fuel tank capacities, which depend on the drivetrain. Models with all-wheel drive use a 15.6-gallon tank, which allows the Terrain to go far: up to 390 miles,1 as calculated using the combined MPG rating.
Only the Elevation is offered with front-wheel drive, sporting a 14.8-gallon fuel tank, which still travels an impressive amount of miles – up to 399 miles,1 as calculated using the combined MPG rating. The Elevation is available with all-wheel drive, and it delivers the same maximum 390-mile range.1
What Affects the Real-World MPG of the Terrain?
Many factors can affect real-world MPG. It's important to remember that the MPG values we've been talking about have been the EPA-estimated values, which may not accurately take into account the climate and terrain of your local driving areas or the traffic conditions you travel in.
Uneven terrain can cost more gasoline to traverse, for example, which may mean spending more on fuel. Inclines have the same effect. Furthermore, stop-and-go traffic, short trips, and sporty driving habits can use up gasoline quicker, as can running the A/C regularly and towing. The GMC Terrain can tow a maximum of 1,500 pounds;4 hauling anything will require more pull from the model and, thus, more gas.
Integrated features, such as standard automatic stop/start and Adaptive Cruise Control, may also affect how the Terrain uses fuel.
Additionally, vehicle condition is another factor that significantly influences GMC Terrain MPG. If your model needs an oil change or has underinflated tires, you may find it requires more gasoline for normal driving.
How To Maximize GMC Terrain MPG
If you want the most out of the fuel tank on the all-new GMC Terrain for sale, consider adopting these driving and service habits:
- Avoid slamming on the brakes
- Avoid frequent stop-and-go traffic
- Avoid excessive idling
- Maintain consistent speeds when on the highway
- Stay up to date on oil changes, tire checks, and other routine care
