The Renault Sport R.S. 01 is a sports racing car manufactured by Renault Sport, the performance division of French automaker Renault. It was originally built to compete in the Renault Sport Trophy, the company's one-make racing series, serving as a replacement for the Renault Mégane Trophy. The car was later homologated for Group GT3 by the SRO Motorsports Group for the car to be able to compete in GT3 class racing series.
The Trophy-spec R.S. 01 is the most powerful one-make racer built by Renault (albeit using the V6 engine from the Nissan GT-R), and also the only race car not based on a production car.
