The Forester is available in four trim levels: 2.5 X, 2.5 X Limited, 2.5 XT and 2.5 XT Limited. All trim levels are equipped with Subaru's Symmetrical All-Wheel Drive and a 2.5-liter horizontally-opposed four-cylinder engine; in both 'X' variants, the engine is naturally-aspirated and produces 170 horsepower, while both 'XT' variants generate 224 horsepower, compliments of an intercooled turbocharger. The 2.5 X gets a 5-speed manual transmission with Incline Start Assist, while all other trims get a 4-speed automatic with manual shift mode (available on the 2.5 X).

In 2009, an optional touch-screen GPS navigation system is offered for the first time on the Forester. Standard safety equipment includes electronic stability and traction control systems, four-wheel anti-lock disc brakes with brake assist, active front head restraints, front side-impact airbags and front and rear side curtain airbags with a rollover sensor.The Subaru Forester is completely redesigned for 2009, with revised exterior styling, an upgraded interior and additional standard equipment and safety features.
