AutoGuide recently found patent filing in Japan for a possible hardcore version of the Scion FR-S, Subaru BRZ, and Toyota GT86. The filing features renderings of a coupe with a new front end, large rear wing, and a new set of wheels. This looks similar to the Subaru STI Performance Concept shown at the New York Auto Show earlier this year.
Now the filing has Toyota and Fuji Heavy Industries - Subaru's parent company - listed as the creators. Not surprising since both have been working together on this coupe.
One of the big questions lingering over this filing aside from when we could actual see this, is how much performance could this coupe have. The STI Performance Concept boasted around 300 horsepower from a turbocharged 2.0L boxer-four.
