The most fuel-efficient Subaru model depends on the model year, trim level, and powertrain. Compact models such as the Subaru Impreza and Subaru Crosstrek are typically among the most efficient gas-powered options in the lineup.

The Subaru Crosstrek is often one of the most fuel-efficient Subaru SUVs. The Forester and Outback provide additional passenger and cargo space while still offering competitive fuel economy.

All-wheel drive may use more fuel than a comparable two-wheel-drive system. Subaru engineers Symmetrical All-Wheel Drive to balance traction, stability, capability, and everyday efficiency.

The Subaru Solterra is fully electric, so it does not use gasoline or receive a traditional MPG rating. Its efficiency is measured using electric driving range and MPGe.

The Subaru Impreza and Crosstrek are strong commuter options because they combine compact dimensions, practical cargo space, efficient performance, and standard all-wheel-drive capability.

Keeping the tires properly inflated, following the recommended maintenance schedule, driving smoothly, limiting unnecessary cargo, and reducing extended idling can help support better fuel economy.
