McLaren have created a special 'Triple Crown livery'. Winning the 24 Hours of Le Mans, the Indy500 and the
F1 Monaco GP means you have achieved what is known as the Triple Crown. Graham Hill is the only driver who has ever managed that. Racing team McLaren also achieved the Triple Crown.
This weekend, the Monaco GP and the Indy500 both take place on Sunday and so McLaren has chosen to appear at the start of the F1 weekend with a different livery.
