With John Martin and Jan Charouz in the Oreca-Nissan No.25 of ADR-Delta, Tor Graves (his full name Sriachavanon Tor) has become, like Karun Chandhok, the first citizen of his country with a classified finish in the 24 Hours of Le Mans, finishing in sixth place in the LM P2 class (13th overall). He succeeds Prince Bira (1914-1985), first Thai in La Sarthe and pioneer of motorsport in his homeland.

Throughout a racing career that began in 1936 after studying at Eton and Cambridge University, then in 1946 after World War II, Prince Birabongse Bhanutej Bhanubandh (who shortened its name to Prince Bira), member of the Thai royal family, scored 27 wins and 28 podiums. He drove twice in the 24 Hours of Le Mans with two prestigious team mates: former double winner Raymond Sommer in 1939 (Alfa Romeo), and Peter Collins in 1954 (Aston Martin). These two participations unfortunately led to two retirements. In 1954, he finally gave up competition.

In 2012, the torch was brilliantly taken up by Thai driver Tor Graves with ADR-Delta: the British team came to La Sarthe as a leader of the team standings in LM P2 in the FIA World Endurance Championship, and started from pole position in the class, and took the checkered flag for the 80th Le Mans 24 Hours. ADR-Delta will be one of the favourites in the fourth round of the World Championship to be held at Silverstone on the 26th August.
