The first official photos [high-res] of the hotly anticipated Cosworth edition of the Subaru Impreza WRX STI hatchback are out in the open. Set to go on sale in this June in the UK only and in a limited-run of just 75 units, the Cosworth Impreza STI CS400 promises to bring supercar-like performance figures to the hot hatch segment.
Starting with the Impreza STI's 2.5-liter boxer unit, Cosworth's engineers installed new high-performance pistons, connecting rods, head gasket and bearings. The tune-up also includes a remapped ECU, modified turbocharger and wastegate, and a custom exhaust system.
