Leading UK motorsport and tuning outfit Cosworth have worked their magic over the Subaru Impreza STI. They said no to the standard STI’s miserable 300PS and 5.2 second 0-100km/h time. They seem to think an STI should have 400PS (295kW), and that it should be able to despatch 100km/h in under four seconds, 3.7 to be precise.
Such belief has led to the birth of a new creation—the Cosworth Impreza STI CS400. Clearly such an impressive boost in power needs more than a few Cossie badges and the lads have turned their attention the engine. The CS400 is not due for release in the UK until June and as such they’re allowing hype to build and aren’t giving away any official details on engine or exhaust mods. We’ll have to stand by for that (or do we?).
Stopping power, on the other hand, has been confirmed to have been developed in partnership with AP Racing. Cosworth seem quite confident that the 355mm six-pot calipers they have fitted to the CS400 will be up to the job.
There will only be 75 Impreza STI CS400s made and we’ll have more details for you sometime between now and June. Like the Focus RS500, though, we’ll just have to admire the pretty pictures and make do with watching TV reviews. There’s about as much chance of the Cossie Rex finding its way down under as there is of Channel Nine making a good version of Top Gear Australia.
