Subaru hopes to build on the success of the Outback by shifting its entire line of Legacy sedans and wagons to all-wheel drive (AWD) and by adding a more luxurious Limited model. The 2.2-liter engine Subaru used in the L and Brighton models gains two horsepower (to 137). The same changes are also performed on the larger 2.5-liter flat-four, used in GT, LSi, and Outback models. The result there is a gain of 10 horsepower (to 165). Both engines can now be teamed with a standard 5-speed OD manual or 4-speed automatic.
