World rally champion Sebastien Loeb wants to avoid being a burden to his team on Saturday when he takes part in the Le Mans 24-hour race for the first time.
The Pescarolo driver from France, who also leads this season's rally standings in a Citroen, and his teammates are on provisional pole for the world's most famous endurance race.
"I have to learn very quickly. The team took a chance when they asked me to come here," Loeb told the race's official website on Thursday.
"They're here to win. I cannot be a burden for my teammates."
Loeb said he had to deal with problems he was not used to in rallying.
"I do not have a lot of experience in these type of races. In rallying, it's less physical," he said.
"I sweat a lot and I need to drink a lot and have good meals."
