Seen laying down impressive passes at Santa Pod Raceway, this Ford Sierra proves that an aerodynamic shape combined with a turbo is a winning combination.

For a few brief years in the 1980s, we got the rear-wheel-drive Ford Sierra here in the United States as the Merkur XR4Ti. What we didn't get was the ultimate performance model, the RS500 Cosworth.

The RS500 Cosworth was fitted with a 2.0 liter turbocharged Coworth twin cam inline four. That engine was good for over 200 horsepower, but could very easily be tuned for more.

How easily, you ask? This YouTube video by Mk1Kieran shows a later RS500 Cosworth that's alleged to have over 900 horsepower. In the video, we see it racing at Santa Pod Raceway, putting down gradually faster and faster times until it's deep into the 10s.
