Sebastian Vettel: 'I may quit Formula 1'

Reigning world champion Sebastian Vettel has revealed that he could quit Formula 1 in five years' time.

The 26-year-old racer responded to a question about whether he would leave Red Bull by making the remarks in German newspaper Welt Am Sonntag.

However, Vettel has insisted that he is happy with his team at the moment but doesn't know what the future holds.

"I can't say. Perhaps I will no longer be driving in five years' time because I no longer have the urge to," Vettel told BBC Sport.

"Perhaps I will compete for another team in five years because I feel ready for a fresh challenge. Every human being evolves as time goes by, priorities shift.

"Right now I feel completely at ease here and I could not imagine driving anywhere else. The car is quick, the team does well - I see no reason to leave. But that does not automatically mean I will stay forever."

The Canadian Grand Prix takes place in Montreal on Sunday.
