Cosworth Impreza STI CS400 – Click above for image gallery

This is the Cosworth Impreza STI CS400, the car Cosworth said would "humble" supercars. With a 0-to-62 sprint happening in just 3.7 seconds it'll be quicker than a whole bunch of exotics, and at £49,995 ($71,368 U.S.), it'll be a whole lot cheaper as well. If that sounds like a boatload of cash for a warmed-over WRX, well, it is. But bear in mind that thanks to factors like the 17.5 percent Value Added Tax, UK pricing is rather different than what pricing in the States would likely look like were Cosworth to sell the CS400 here.

The 395-horsepower, 398-pound-foot Cossie Scooby benefits from a thorough rework of its boxer-engined details, boasting new pistons, con-rods, turbocharger, exhaust and ECU mapping among its many modifications. Aiding the Impreza's all-wheel drive get power to the ground is a lowered suspension with components from Bilstein and Eibach.

Looks-wise, a different front bumper fitted with mesh inserts, a rear spoiler, a track widened by 12 millimeters, and 18-inch alloys over bigger AP brakes will make sure Subaru cognescenti don't confuse you with anything else. Identification will also be made easier by the fact that there will only be 75 made for the UK market only, and available it'll be available in red, silver, and dark gray. Thanks to everyone for the tips!

      I don't doubt that Cosworth did a quality job on this build, and I'd be stupid to not be jealous of the Brits with their heavily modded, WARRANTIED cars (ie. FQ Evo series). But putting that pricetag on it, is ridiculous. And someone please tell me why Cosworth couldn't wait to do this build on the '11 STI Sedan? Would've been a much nicer outcome IMO.

      @FNDave: I'm happy for your BUDDY and HIS car... Get off his nuts. :thumbsup:

      Oh my god... Yes please. I'll take two.
      • 4 Years Ago
      looks clean..I like it!
        • 4 Years Ago
        The front looks good, the rest looks like a Ford Focus.
      • 4 Years Ago
      I'd tap that.
      • 4 Years Ago
      Well whiners, apparently my BUDDY does not know what he is doing and my BUDDY doesn't have the slightest clue. Well my BUDDY isn't some fly by night teenager that went out and bought this car with his parents money. My BUDDY did a bunch of research before he decided to do the mods. The motor can withstand up to 500HP before diving into the internals and that is a fact. So I think my BUDDY knows a thing or two, and so do I since I do engine R&D for a big 3 company.

      I don't hate this car I just stated with a little know how you can get the same results or better. So I'll thank my BUDDY for all of you and tell him about the jealous whiners on here. Now go drive home in your 12 year old Corolla to your wife/girlfriend.

        Here it is. Plain and simple.

        First. You hit the nail on the head. I drive an old car. I'm a father of 2, and am putting myself through college ( Network Engineering ). Guess what takes priority? Daddy's sweet ride or family?

        As to your Buddy, which you keep stroking. It's not even YOUR car, man. It's YOUR BUDDY's. He seems like the humble one. He's not on here bragging about how bad-ass he is.

        He's without a warranty ( unlike this car ).
        He wasn't consulted about how to properly build a Scooby. I'm pretty sure, and this article proves it, that Cosworth knows how to build a reliable ( see factory reliable, not tuner reliable ) car.

        Noone would give a @#$! about your buddy's Subaru. THIS IS NOT IMPORT TUNER, DUDE. Noone would pay the money Cosworth can demand ( to your friend ). He's not a legendary tuner house who revamps already good cars.
        Your buddy is just one guy. Probably one who frequents NASIOC. Great.

        I doubt you understand what I'm saying, so I'll tl;dr.

        You probably make more money than me. I congratulate your hard work.
        You likely drive a nicer car than I do. I'll have that, no doubt, when I'm done in school.

        That doesn't change the fact that you buddy wouldn't get time of day on Autoblog like Cosworth does. Stop bringing him up.

      Not bad aside from the crap paint job.
      • 4 Years Ago
      Hmmmmm...so they add 90hp to the car and it requires that some engine internals need upgrading??? How sad.

        • 4 Years Ago
        Everybody and their neighbor knows about Cosworth. It just irritates me when stock internals need to be addressed when you haven't even doubled the cars output. For $70k+, I hope they swapped in a better crank while they're at it.

        Anyone who buys this car was born yesterday.
        • 4 Years Ago
        Its an STI not an Evo.
        • 4 Years Ago
        Cars today aren't built like they were back in the day (which was a Wednesday). The emphasis is on weight savings, so blocks/cranks/rods aren't built with a factor of safety of 7 anymore...you can take your double rule and subtract probably 60-70%.
        • 4 Years Ago
        Yes, it does, to ensure reliability over tens (if not hundreds) of thousands of miles.
      • 4 Years Ago
      In the UK it's just 10k (pounds) under a GT-R, so it's brand new territory for a Scooby. Performance and handling-wise it's there with the best, but the rest of the car is just a compact hatch in terms of perceived quality, equipment and the rest; built to cost 20k in standard form.

      In any case, I'm sure they'll be sold pretty quickly given it's limited availability and the legions of fans of the WRX and its derivatives in Britain.

      I would give my first born child to own this car.

      For 72k?

      I'll pass...If I had 72k...this is the last car I'd buy....I'd buy 2 Ford Fiestas and an Ariel Atom with that money before buying this....
        • 4 Years Ago
        @Tim
        Now I realize they put that number in the story... but have you EVER seen a car come over from the UK and sell for its direct conversion price? No. They're cheaper here. Ya, it would still be a lot of money for an STi, but it's one hot STI, IMO.
      • 4 Years Ago
      Big deal, my buddies WRX STi makes about 420hp and costs half of what this car costs. And his modifications were just from a turbo, injectors, intake, exhaust and cold air induction. He didn't have to dive into the internals, unless he wants to go for more. Even then, he has not even got the final tune for the ECU yet, which will unleash more power. It is tastefully done and it doesn't look far off from what this car looks like that JUST came out.

        • 4 Years Ago
        Keep in mind this is also a brand new car, not an older model. 2010 STi's start at $35k, so unless you know about a bunch of uber-deals I don't, you're not going to get that much more performance over a base for $685...which is all you could spend and be at half the price of this car.
        • 4 Years Ago
        Yeah, and he'll be lucky if it lasts more than 30-40k miles.
        • 4 Years Ago
        Well my buddy DID do it right any got into the internals. The motor's good for 500hp, and SHOULD last (Pauter rods, Cosworth pistons, Cosworth heads, etc), but yeah. He's probably got 50k into it by now.
