LE MANS, France– Former Formula One world champion Jenson Button admits that his debut in the Le Mans 24 Hour Race is likely to leave him with the sensation of driving at 500km/h, “a speed from another world”.

Button is one of the draw cards at the classic French endurance race this weekend along with fellow former F1 world champion and McLaren teammate Fernando Alonso.

The British star, F1 champion in 2009, said he is eager to get his race underway but is wary of driving at night.

“I have only done two laps in the night and others at sunrise so I do not have much experience but I can already say that it is difficult,” said Button.

“But we will get accustomed to the darkness.”

Button pinpointed where he believes the greatest challenge will be — the Porsche curves.

“That is a huge shock! At night, you feel you are going at 500km/h. The blue lights (which signal overtaking), they too are a shock. You have to give your eyes and your brain time to get used to it.”

Button, 38, who retired from Formula One before the 2016 season, will race at Le Mans for Russian team SMP, sharing the drive with Mikhail Aleshin, who has raced in IndyCar, and Vitaly Petrov, another F1 refugee.

“It’s very different to Formula One. What surprised me most is the speed around the fast bends. It’s phenomenal.

“In the ‘S Porsche’ sector, the speed is from another world. If you get the chance to follow the race there, go and see the cars pass.”

Button said it had always been a dream of his to race at Le Mans where he will share the spotlight with Alonso who is looking to complete the second leg of motor racing’s ‘Triple Crown’ of F1, Le Mans and Indy 500 titles. afp
