James May has suggested he and his co-hosts are "getting a bit old" to do 'The Grand Tour'.
The former 'Top Gear' star - who co-presented the BBC motoring programme alongside Jeremy Clarkson and Richard Hammond from 2003 until 2015 - has insisted that the Amazon Prime Video series, which the trio launched in 2016, was never axed but is "naturally" coming to a close.
He told RadioTimes.com: "I mean, some people have said we've been cancelled.
"But really we're getting quite close to the end of our contract, but we didn't really have any particular plans to keep going because we're all really just getting a bit old. It might be time to let someone else have a crack at it."
The 60-year-old star insists it's not the last time fans will see himself, Jeremy, 63, and Richard, 53, on screens.
He said: "It doesn't mean we're going to stop making TV. We might still make our individual things - farming or science or mending cars or whatever it is we get up to.
"But I don't know, to be honest. No one has told us to go away. It's reaching its natural end, like parties do. There comes a point at 4am when it is over."
First up is 'The Grand Tour: Eurocrash' special, which will arrive on Prime Video on June 16, and sees them tackle a 1,400-mile trip from Gdansk in Poland, through Slovakia, Hungary and Slovenia.
And there are two more "scary" seasons to come.
Jeremy said: "For the next one – in fact, the next two – we’re back on slightly scary ground, doing things that we used to do when we were in our 30s and 40s. But now we’re in our 50s and 60s, so I'm slightly nervous about the next two."
James admitted there is a "massive contrast" between the upcoming series, and joked one part, in particular, could "finish Clarkson off".
He added: "We've got some interesting cars to drive. There's going to be a massive contrast with this east European one. Where we’re going next is quite tough, with camping, which might finish Clarkson off.
"Hammond will love it because he loves camping. I'm pretty excited about it because it’s a bit of the world I've never been to, it's slightly dangerous and edgy."
