Here’s an interesting video clip* that shows how the Ford Focus RS500 makes its way from standard RS on the production line to a limited edition RS500.
A standard RS rolls off the Saarlouis production line (in Germany). It’s then fitted with the necessary gubbins to give the 5-cylinder engine its extra power, and then gets those smart black alloys. After that the almost-finished RS500 is parcelled off to company 3M, who coat the Panther Black paintwork with the special matt black foil that gives the RS500 its distinctive appearance.
* well, I think it’s interesting!
