Subaru Impreza STI Cosworth CS400

We've been hearing about it for a while now, and finally some more details are forthcoming on the Cosworth STI. While it saddens me that the latest Cosworth road car won't have a Ford badge on it, a Cosworth STI makes a lot of sense - a turbocharged, four wheel drive rally car are things both of the brands are well known for.  Up until now we've only seen a teaser shot of the rear badging (how exciting!) but yesterday a few more details leaked out on this most-awesome-of-scoobies, and it sounds like it's going to be a serious piece of kit.

Called the STI Cosworth CS400, the 400 will stand for how many ponies reside under the Cosworth/Impreza's hood.  Cosworth hasn't released any details on how it's packing an extra 100 horsepower in it's 2.5L turbocharged horizontally-opposed four, but I'd bet  on better breathing and cooling along with more boost.  Peak power of 400bhp comes at 5,750rpm, which is 250 lower than the stock STI's power peak.  Cosworth hasn't released torque specs on the CS400, but I'm going to venture a guess: a lot.  We do know there's going to be a free-flow exhaust to let out that nasty Subaru snarl!  Cosworth says the upgrade will shave a crazy 1.5 seconds off the STI's 0-60 time, dropping it from 5.2 seconds (pretty fast) to 3.7 seconds (hello, Lamborghinis!)

Besides the copious amount of extra power, the Cosworth STI will benefit from chassis modifications.  An upgraded, lowered and adjustable suspension will make the sort-of-flabby STI go around corners faster, and a special AP Racing designed brake system (355mm rotors with 6-piston calipers up front) will bring all that throbbing horsepower to a stop.

Beyond that, the Cosworth CS400 will have some redesigned bodywork so people know you spent a ton of money on it, along with Cosworth badges and interior tweaks.  Cosworth will only be making 75 of these super-subies, which will go on sale some time in June, and whether it'll be UK-only or for all of mainland Europe is also up in the air.  We'll let you know more as soon as we do!
