Renault and Caterham to develop affordable sports cars

Renault and Caterham are to join forces to create new, more affordable sports cars under the Alpine badge. The two groups will establish a jointly owned new group – Société des Automobiles Alpine Caterham – under the leadership of Bernard Ollivier and will develop models to be sold as both Renault Alpine and Caterham.
