By reviewing and modifying every aspect of the IMPREZA's basic structure such as the third generation Horizontally-Opposed Boxer engine, the newly developed Lineartronic (CVT), the reduction of overall weight, and advances in aerodynamics, significant progress was made in the vehicle's environmental friendliness, most of all fuel efficiency. Furthermore, special attention was paid to the further refinement of fun-to-drive characteristics. The new IMPREZA offers a spacious and comfortable cabin with high-quality feel, without increase in body size. IMPREZA SPORT, a 5-door hatchback with stylish exterior and interior and spacious cabin and cargo room, provides comfort even in long rides. IMPREZA G4 is the next generation sporty sedan with a high level of balance between driving performance and environmental friendliness.
