Cosworth to tune Impreza STI

Subaru is teaming up with Cosworth to make a souped-up version of the Impreza STI.

Subaru is saying little else about the car, only that it will 'enhance the performance, handling and styling of the Impreza STI.'

The project is being described as a 'one-off' between the two companies. Full performance and pricing details will be announced next month.
