The base Impreza model features a 173-hp four-cylinder, engine with the option of either an automatic or manual transmission. The sporty WRX model comes with a turbocharged version that gets 224 horsepower. All versions are all-wheel drive and come in either hatchback or sedan form. The redesign gives the Impreza an appearance far different from that of its predecessor, as it is now rounder and subtler and sits on a longer wheelbase. Most noticeably, the grille features just one frame instead of three. The interior provides added comfort and luxury. Safety features such as six airbags and four-wheel antilock disc brakes are standard. The Impreza receives an exterior redesign and some interior changes for 2008.
