Both manufacturers say that they still intend to launch new sports cars, and Renault says its Alpine is 90 per cent complete and will appear in 2016.
Renault and Caterham Group signed an agreement in November 2012, the plan being to develop and manufacture sports cars through a joint venture, Société des Automobiles Alpine Caterham, owned 50/50 by the two partners.
That firm is now changing its name to Société des Automobiles Alpine, but Renault says that it could still cooperate with Caterham Group on future projects.
The two had each intended to launch their own badged car on a shared platform, Renault’s version reviving the iconic Alpine brand. The cars were to be built in a factory in Dieppe, France, which Renault retains following the latest developments.
Industry rumours suggest that design changes following mixed reactions to a concept prototype contributed to the delays on the new cars and also resulted in tensions between the UK and French design teams.
