Cosworth Impreza STi CS400: First Look

Jay Williams - 20/May/2010

United Kingdom - Subaru and Cosworth have teamed up to produce supercar-like performance figures for the hot hatch segment.

Introducing, the Cosworth Impreza STi CS400. This beast of a car is based on the Subaru STi hatch, but unlike the standard 227kW of power produced, this new machine boasts a much larger power figure.

Cosworth have taken the standard 2.5-litre Boxer turbo engine and increased maximum power to  295kW and pushed torque figures to 540Nm. The improved power means the  Cosworth Impreza STi CS400 can rocket from 0 to 100km/h in 3.7 seconds, before topping out at a limited 250km/h.

Just to put that into perspective, that's the same amount of time it takes a V12 Ferrari 599 GTB Fiorano  to accelerate from 0 to 100km/h.

Cosworth have added new pistons, connecting rods, a redesigned head gasket and a new turbo with a new compressor design and wastegate actuator. In addition Cosworth have also remapped the ECU.

Other additions include 10mm lowered suspension, a 12mm wider track and AP Racing 355mm discs brakes.

At a glance you will notice a few styling changes that include a new front bumper, mesh grille, foglights and a new rear spoiler. Wheels are a set of new 18-inch alloys. The Cosworth Impreza STi CS400 comes with in a choice of three colours - silver, dark grey or red.

Meanwhile, the interior features new Recaro front seats, a piano black centre console, privacy glass and Cosworth badges.

The Cosworth Impreza STi CS400 is limited to just 75 units and will be manufactured exclusively for the UK. Pricing starts at £49,995 (AUD$86,984).
