The latest incarnation of the Subaru WRX STI isn't the only vehicle Subaru is showcasing at Tokyo this year. Alongside the Japanese automaker's rally-racer will be two new concepts and Japanese-market limited-edition models of the Impreza hatchback and the Legacy Outback wagon.

The first vehicle is the EXIGA Concept, a seven-passenger wagon said to combine utility with a sporting driving experience. Power comes from what's likely the same turbocharged 2.0-liter boxer four that motivates the Impreza WRX models and is sent to all four wheels via a five-speed automatic transmission. A large glass roof no doubt lends the EXIGA Concept an airy atmosphere, while theater-style seating affords every passenger an unobstructed view.

Subaru's second concept is the G4e. An electric vehicle, the G4e Concept offers seating for five and optimizes interior space by storing the batteries in the floor. We'd guess that will also do wonders for the concept's handling, as batteries tend to be rather heavy, and this layout should provide for a low center of gravity. The G4e Concept somewhat mimics the styling of many of today's "tall" cars such as the Toyota Matrix and Pontiac Vibe, though it's slightly edgier. Subaru claims a 200 km (124 mile) range from the G4e, thanks to lithium-ion batteries and a lightweight body.

ile Subaru doesn't seem to have much to say about them, we've included images of the Impreza BEAMS Edition and Legacy Outback Urban selection as well. Both appear to be limited-edition models for Japanese consumers only, with the only cosmetic modifications. The BEAMS Impreza supposedly gets special colors and equipment selection (BEAMS is a popular Japanese boutique), while the Legacy Outback Urban selection comes in a unique "lightening red" color with silver side mirrors and roof rails, along with leather and Alcantara seating. Both cars will likely hit Japanese showrooms in early 2008.
