2026 GMC Terrain Fuel Economy

The Elevation FWD's 8.8 L/100km combined is the most efficient configuration and its smaller 56L tank still delivers an estimated 636 kilometres of range, the longest of any Terrain trim.

The AWD trims all carry a larger 59 litre tank, which nearly offsets their slightly higher consumption. Stepping up to the AT4 or Denali doesn't cost additional fuel economy over the Elevation AWD, making either premium trim a straightforward choice for buyers who want more features without paying more for gas.

Trim Drive City Highway Combined Tank Est. Range
Elevation FWD FWD 9.2 L/100km 8.3 L/100km 8.8 L/100km 56L ~636 km
Elevation AWD AWD 9.9 L/100km 8.5 L/100km 9.3 L/100km 59L ~632 km
AT4 AWD AWD 9.9 L/100km 8.9 L/100km 9.5 L/100km 59L ~621 km
Denali AWD AWD 9.9 L/100km 8.9 L/100km 9.5 L/100km 59L ~621 km

FWD vs. AWD for Economical Buyers

The fuel economy difference between FWD and AWD on the Terrain is modest, approximately 0.5 L/100 km combined on the Elevation. If you’re a Newfie who frequently contends with icy roads, wet conditions, and unpredictable weather all year round, the AWD traction offers meaningful real-world benefits for a small efficiency trade-off. The Elevation AWD, at $38,499, represents strong value for entry into AWD capability without stepping up to AT4 or Denali territory.

All trims run on regular unleaded fuel and feature a turbocharged engine that delivers its torque early in the rev range, making for responsive, confident driving in city traffic without burning excess fuel to get there.
