Subaru Impreza WRX STI Cosworth CS400

Here it is – Cosworth’s insane road-going version of the Subaru Impreza WRX STI. The model will go on sale in June in the UK and will be limited to a production run of just 75 units.

Cosworth engineers took the Impreza WRX STI’s 2.5L boxer engine and added high-performance pistons, connecting rods, head gasket and bearings, remapped the ECU, modified turbocharger and wastegate and threw in a custom exhaust system.

All that gives the Subaru Impreza WRX STI Cosworth CS400 a total of 395-hp with a maximum torque of 398 lb-ft. That allows it to go from 0-62 mph in 3.7 seconds with a top speed electronically governed at 155 mph. The Subaru Impreza WRX STI Cosworth CS400 also gets a revamped suspension (lowers ride height by 10 mm) and a new chassis, which is a joint effort between Cosworth, Bilstein and Eibach.

Styling upgrades include a new front bumper, foglights, mesh grille and a rear spoiler. The Subaru Impreza WRX STI Cosworth CS400 rides on 18-inch alloy wheels.

    Now this is a fine looking toy to drive around.

    Next, Mazda needs to pump up the MX-5. Can't wait for that in matte black. When are they due out?
