Ford “FOCOS”: AWD Focus‏ RS Cosworth Build

This Ford Focus is the subject of a build thread on by it’s owner/builder, forum member “TurboGuido” of Ellmer Autosport in Germany. They took a standard issue, bare spec, absolutely stripped out base model Ford Focus and merged it with a modified, bad to the bone AWD Cosworth Sierra sedan, blending the two to create the 529 horsepower engine’d,  Ford “FOCOS” that you see before you. Even the name has been modified. We like it already. This creation clicks all of the right boxes for us. Let’s see, what do we have here: Engine swap. Check. Mod thread. Check. Drive train swap. Check. White car with roll cage and Compomotive rims. Check. Check. Sleeper. Well, let’s just move right on, shall we?


To begin with, everything was stripped out of the Focus, leaving just a body to combine the Sierra’s AWD drive train and the turbo Cossie engine. Focus RS wheel arches, H&R coil overs and AP Racing 378 mm, 6 Piston front and 330 mm, 4 piston rear brakes were just some of the quality parts named in the impressive ground up project, and a full specs list is attached below, after the featured link.


Overall, the build is very tastefully executed, looking like something that could have come straight out of Ford Motorsport Racing’s division. What’s possibly most impressive is that once it was finally completed, it remained road legal and street registered, which is something that wouldn’t be nearly as likely for us here in California.


After driving it around for some time, the decision was made to tone it down a bit to make it a bit more civilized for daily driving. It turns out that between banging his head on the roll cage and his leg falling asleep in the race seat, it was time to re-think some of the race part decisions and gear it towards a little more comfort. So, in went the full interior swap of a Focus RS (Interior swap: Check), including air conditioning and airbags, making it a lot safer and quieter for his wife and son to enjoy, as well.


The problem with projects is, well, that they are projects, which means they are never finished and in a constant form of development. If that really is a “problem”, after all…


The final destiny for this particular build was dismantling the whole car and selling everything, with another AWD Focus RS Cosworth build in the works, but this time around with a completely standard spec exterior for the ultimate sleeper look. We hope to feature that build as soon as it is posted. At that point we will finally be able to say: Sleeper? Check!
