Vehicle Details

Subaru's third generation of the iconic WRX/STI platform was offered in a five-door hatchback (GH/GR), and four-door sedan (GE/GV) and resulted in discontinuation of the wagon format.

While the exterior sported bold new changes, the legacy of the EJ20 and EJ25 flat four boxer powertrain was again carried forward, fundamentally the same as previous generations enabling the aftermarket scene to hit the ground running with an extensive range of ready to use parts.
