Systems Operation


Subaru transmissions, drivetrains, and chassis systems promote fuel economy as well.




All automatic and manual transmissions feature overdrive gear ratios in their top one or two gears, which allows the engine to run at lower speeds, conserving fuel. In addition, automatic transmissions have lockup torque converters to maximize the utilization of engine power.


The Lineartronic CVT (Continuously Variable Transmission) is engineered for improved fuel economy, helping the 2012 Impreza to become the most fuel efficient All-Wheel Drive car in America at 36 miles per gallon.1


Symmetrical All-Wheel Drive


With its integrated transfer case, Symmetrical All-Wheel Drive has reduced reciprocating mass, which takes less engine power to operate.


Chassis Components


All models have reduced-friction axle joints.


The front brake pads on Impreza and Forester models have return springs added to reduce friction as a result of brake drag. Plus, the 2012 Impreza has electric power-assisted steering, which eliminates the need for a hydraulic steering oil pump that requires engine power to operate it.
