Subaru Viziv Performance Concept could hint to the next WRX

Subaru has uncovered an attractive concept at the Tokyo Motor Show. The only trouble is, nobody's quite sure what it previews.

The front end looks properly aggressive, with LED headlights carrying the same C shape as previous Subarus

There're some large air intakes just under the lights.

On the car's side, there are some large flared fenders, and the body above the taillight moves upward into an integrated spoiler.

The side mirrors are also tiny, while traditional door handles are replaced with button releases.

The five-person sedan also features plenty of carbon fiber for the front lip, roof, side sills and rear diffuser.

A 20-inch wheel and Bridgestone Potenza tire package completes the concept's exterior.

With a 107.4-inch wheelbase, the Viziv Performance Concept could preview a new, larger WRX compared to today's model that rides on a 104.3-inch wheelbase. 

Or, it could be a precursor to a slightly smaller next-generation Legacy. The current Legacy uses a 108.3-inch wheelbase.

Subaru outfits the Viziv Performance Concept with its  next-generation EyeSight driver-assist system.

I'm leaning more toward WRX than Legacy.
