New Zealand motor racing driver Brendon Hartley is stunned by the quality of competition heading into this weekend's Le Mans 24-hour endurance race. 

The prestigious race has been operating since 1928 and the winner is the car that travels the greatest distance in a 24-hour period around the 13.6km circuit. 

The biggest names in vehicle manufacturing are taking part —with Genesis, Ford and McLaren joining the party next year— and Hartley says the level of driver is insane. 

He told Mike Hosking every single driver in their category are paid professionals and top class drivers. 

“I would argue there’s... you can’t find a race anywhere in the world where you have so many of the world’s top drivers all in one place at the same time.”
