Patrice Ratti, managing director of Renault Sport Cars, said: "We successfully completed the project of a slightly crazy car.

"It was a joint effort by the Renault Sport Cars and Renault Sport Racing teams. This Clio R.S. refines the expertise of Renault Sport engineers whilst exploring new avenues for the future".

The Renault Sport team will be in Monaco this weekend to demonstrate how Renault makes the connection between the racetrack and the roadand to reveal what is behind the design of this special Clio R.S.

Whether the car will go into production has still to be confirmed.
