Jeremy Clarkson Gears for change
'Top Gear' hosts Jeremy Clarkson, Richard Hammond and James May expect to quit the show if the format becomes tired
The 'Top Gear' presenters will not stay with the show forever.
Jeremy Clarkson, Richard Hammond and James May - who joined the programme in 2003, a year after the others - will walk away from the programme when the current format becomes tired.
Producer Andy Wilman explained to Radio Times magazine: "It's not like a team taking over 'Holiday' and carrying on as before.
"We took it, made it what we want it to be, and when people don't want to watch us any more, somebody else will take it and do something else.
"We've behaved like a band putting out albums as opposed to a TV show putting out series. You don't know what direction a band will go."
In the mean time, the presenters have vowed to tone down the "tomfoolery" in the new series of the show as they are aware that not everyone shares their sense of humour.
James said: "The keen observer will notice a subtle change to this series, a slight retreat from the 'Last of the Summer Wine' tomfoolery.
"It's easy to get carried away - it's like drinking, you start to believe you're funny and other people might not."
