Toyota and Subaru are working on a new RWD sporty coupes employing a revised version of the Subaru Impreza's platform, boxer engine and transmission.

The Toyota version will be sold exclusively in Japan, while the Subaru-badged model will be marketed worldwide.

Both models will be powered by Subaru's well-known 4WD powertrain and modify it to create a new rear-wheel-drive setup. Slated to be built at Subaru's Gunma plant in Japan, both Toyota and Subaru models will employ a revised version of the naturally aspirated boxer 2.0-liter unit generating around 220 horsepower at 6,500 rpm, mated to a six-speed manual gearbox from the current Impreza WRX STI.

Set to be unveiled in 2011, the coupes are expected to be priced starting just under $20,000.
