Porsche World Endurance Championship driver Mark Webber describes his need for speed as being like a drug, and after a career that has seen him strapped into some of the world's fastest machines for most of the past 15 years, he announced on Friday that he is going cold turkey.
Known for his loquacious and outgoing nature, Webber, speaking at a news conference ahead of this weekend's 6 Hours of Fuji, said he was bringing his career to an end because he began to question his motivation.
"Sometimes I would be in the car this year and I would ask myself 'Why am I doing this?'" said the 40-year-old Australian who has raced in the WEC for the past two seasons.
