Subaru Impreza WRX STI CS400 | Spotted


Subarus and British tuning corporations go collectively like influencers and wrapped supercars. The title that’ll seemingly spring to thoughts is Prodrive, the engineering powerhouse behind the Subaru rally group and a collection of red-hot specials just like the P1. Hell, even Litchfield made a reputation for itself by importing JDM-spec vehicles and giving them an intensive overhaul within the form of the Sort 25. However we frequently overlook that an organization as soon as famed for giving us probably the most hardcore Fords in Europe additionally had a go at boosting the boxer.

We’re speaking, after all, about Cosworth. Clearly, Cosworth’s historical past spans far past its ties with Ford, significantly as an engine builder for, effectively, just about each motorsport self-discipline, however on the street automotive aspect of issues its most iconic and most up-to-date creations had been these based mostly on choices from the blue ovals. That was actually the case in 2010, making it all of the extra shocking when it was Cosworth, not Prodrive, that launched a hardcore limited-edition model of the STI hatch.

Let’s not overlook the UK-spec Impreza WRX STI hatch wasn’t practically as effectively obtained because the generations that got here earlier than it. Partly as a result of the Impreza’s rally wins got here within the type of the coupe and saloon vehicles, but additionally as a result of the preliminary STI providing simply wasn’t pretty much as good as individuals had been anticipating. Excellent news for Cosworth, then.

The corporate left no stone unturned when creating the CS400. The chassis underwent a variety of adjustments, together with new Bilstein dampers and Eibach springs, decreasing the trip top by 15mm. The bushings had been additionally upgraded, whereas the brand new Cosworth-branded AP Racing brakes featured six-piston calipers up entrance for face-squashing stopping energy. In entrance of them sit 18-inch rims which, sadly, aren’t painted in gold – however they’re lighter than the wheels on the usual STI.

Naturally, this being Cosworth, all the most important adjustments might be discovered underneath the bonnet. Subaru’s 2.5-litre boxer was carried over to the CS400, solely it was stripped down and reworked from the bottom up. An even bigger turbo was fitted, together with new con-rods, gaskets, bearings and pistons. Throw in a brand new consumption and freer flowing exhaust, and energy jumped from the inventory 300hp to – if the title didn’t give it away – a daft 400hp. Certain there are many sizzling hatches that may attain that stage of energy at this time, however again in 2010 that was mighty spectacular for a household hatch.

As was the value. The CS400 value a bit of underneath £50,000 new, which, on the time, wasn’t far off the price of an R35 Nissan GT-R. It additionally didn’t assist that the automotive was polarising to say the least. Some journalists hailed it as the perfect Impreza in a decade, whereas others criticised its energy supply and the positioning that left it too near the R35. Both approach, the CS400 is the sort of automotive it’s good to have to drive to see what all of the fuss is about.

The alternatives to take action do not crop up all that always given Cosworth solely produced 75 examples. This CS400 is quantity 30 and seems to be one of many cleanest Impreza WRX STIs on the market. Solely 12,000 miles have been coated because it was registered in 2010 and it’s accompanied by a full service and MOT historical past. It’s even had some latest work performed on the brakes, which might’t have been low-cost, together with a cambelt change final yr. True, £55,000 is some huge cash for a Impreza hatch, particularly as you may get an RA-R for related cash. Nevertheless it gained’t be pretty much as good a day by day driver because the CS400. Neither is it as uncommon…
