British engineering firm Prodrive, known mostly in the U.S. for their Subaru Impreza WRX upgrades, is designing a new small, light and agile supercar. The company also builds the WRC cars for Subaru as well as Aston Martin's DBR9 GT racing car. Codenamed the P2, it will use Impreza mechanicals in a car about the size of a subcompact. Subaru's well-balanced 2.0-liter flat four and AWD system will only need to push/pull about 2,200 pounds. The company will use the car as a testbed for new technologies like stability and turbo anti-lag systems. There is no production plan at the present time.
