Referring to a number of vehicles built by Ford and tuned by Cosworth for the purposes of touring car or rally racing. Most notably among them are the Sierra and Escort Cosworth RS's, which featured the turbocharged 2.0L Cosworth YB series of engines, famed for their tunability.

These vehicles were made in somewhat limited quantities available with 5-speed manual tranismissions in RWD or AWD with a particular rear-wheel bias. Though they were sold primarily in Europe, a handful were exported to America as the Merkur XR4Ti, essentially a rebadged Sierra Cosworth RS; the Cossie Escort was never sold in the US.
That chav in his riced-up Leone thought he was hot shit, til I served him up pulling onto the M1 with my Cossie.

To possess amazing qualities and be a generally cool person. Cossy is a term to describe something that cannot be described with words like: Cool, Rad, Sweet, Gnarly Etc.

If one is awesome enough to be called Cossy, you know damn right that they are cooler than cool!
You're a pretty cool guy, but I've been told i'm Cossy. Compared to me you're lame!
