Subaru WRX STI Car
Subaru WRX STI Car Legendary tuner Cosworth has collaborated with Japanese car maker Subaru to develop the Cosworth Impreza STI CS400 based on the Impreza WRX STI 'hot-hatch'.
The first genuine Cosworth-developed road car since 1996, the Cosworth Impreza STI CS400 is powered by a heavily tweaked 2.5-litre turbocharged ‘Boxer’ engine that produces 33 per cent more power than the donor car. Ddrawing heavily on Cosworth’s extensive Formula 1 experience, the engine, which drives all four wheels via a six-speed manual gearbox, boasts an impressive 294 kW and a 0-100 km/h time of just 3.7 seconds, making it one of the world's most accelerative hatchbacks. The quarter mile is covered in a brisk 12.75 seconds at a terminal speed of 172 km/h. Top speed is limited to 250 km/h
The Cosworth Impreza STI CS400 features an extensive range of Cosworth-engineered components in the engine, turbo system, exhaust, suspension, brakes and wheels, plus subtle improvements to the exterior and interior styling to create a truly distinctive high performance car with everyday hatchback practicality.
Available in a choice of three exterior colours - Spark Silver, Dark Grey and San Remo Red - the Cosworth Impreza STI is, quite sadly, for the UK market only and is priced from £49,995 (AU$86,727). Only 75 units will be produced.
