Subaru and Cosworth finally broke the embargo and released further details on the highly anticipated CS400 special editions Impreza. The car has 400 hp and it’s said to be supercar-hot! The Cosworth Impreza STI CS400 is limited to only 75 units and will go on sale in Britain starting from June 2010.

This hot Impreza hatchback comes with a highly modified engine which delivers 400PS (395bhp) at 5,750rpm and that gives it unbelievable performance! Zero to 60 mph takes only 3.7 seconds in this car which is fantastic. In fact it’ll be the fastest accelerating all-wheel-drive car in the market.

Cosworth also features a high performance braking package from AP Racing with six-pot callipers and 355mm discs at the front to remain in check at all time. It’ll also get tweaked suspension and exhaust system and will come with a number of exterior and interior changes to be distinguished from normal Imprezas.

Full details of pricing and technical specification will be announced closer to the on-sale date.
