Whereas Alpine is back in the European Le Mans Series (13th of April), the American team Starworks Motorsports will be absent from the opening round of the FIA World Endurance Championship (14th of April).

European Le Mans Series will be the debut for the Alpine-Nissan. Entered by the French team Signatech Alpine in the European Le Mans Series (ELMS), the Alpine Nissan (based on Oreca 03 chassis) is now called A 450. This name refers to the fiftieth anniversary of the brand founded by Jean Rédélé, and also the lineage of Renault-Alpine prototypes at the 24 Hours of Le Mans in the mid 70's : A441C 1975 (driven by the all female duo of Marie-Claude Beaumont and Lella Lombardi), the A442 (1976-1977), the A443 (1978), and of course the A442B that won in La Sarthe in 1978, in the hands of Didier Pironi and Jean-Pierre Jaussaud.
