The long version

Renault named it for its Formula 1 engine partner and originally capped production at 3,800 units, the bare minimum the Group A homologation rules required, finished exclusively in a specific blue with gold wheels that became the car's signature. Demand outran that number almost immediately, and Renault built two further Williams series to meet it, extending a car that was only ever supposed to exist to satisfy a rulebook. It spent years as a cheap enthusiast's classic before values started climbing hard in the last decade, pulling clean survivors out of daily use and into the same collector gravity that caught the 205 GTI before it.
