The 2015 Subaru Forester is a wagon-like SUV based on the Subaru Impreza/Legacy platform, making it similar to crossover vehicles made by other manufacturers. It features Subaru's full-time all-wheel drive system and is powered by Subaru's four-cylinder engines.
The Subaru Forester is available in several trims, with the type of engine and transmission the major differentiating factors between trims. The 2.5i, 2.5 Premium, 2.5 Limited and 2.5 Touring trims are powered by a 2.5-liter four-cylinder that produces 170 peak horsepower and 174 foot-pounds of torque, while the 2.0XT contains a turbocharged 2-liter engine. While the 2.0XT's engine has less displacement than the engine in the 2.5 trims, its 250 peak horsepower and 258 foot-pounds of torque are significantly more powerful.
A six-speed manual transmission is standard on 2.5i and 2.5 Premium models, while all other trims come standard with a continuously-variable transmission. The CVT is an optional feature on the 2.5i and 2.5 premium, however. CVT transmissions automatically adjust the effective gear ratio between the wheels and the final drive gear, effectively giving the transmission an infinite number of gears to best match conditions on the road. CVT transmissions also improve fuel economy in the 2.5 Subaru Foresters, with CVT Foresters getting 27 miles to the gallon compared to 25 miles per gallon for Foresters with manual transmissions. The 2.0XT Forester also gets 25 miles per gallon.
