The 50-year-old TV presenter and co-stars Matt Le Blanc, Chris Harris, Sabine Schmitz, Eddie Jordan and Rory Reid have taken over from previous stars Jeremy Clarkson, Richard Hammond and James May but Chris insisted he has no nerves ahead of his debut on the BBC motoring show.

In a letter to fans published in the June issue of Top Gear Magazine, Chris said: "There's nothing left for us to be nervous about - we've each aged a thousand years in the past 10 months. We're done. There's nothing we can do now except sit back and enjoy our favourite show."

Chris, who has presented shows including 'TFI Friday', 'The One Show', 'Don't Forget Your Toothbrush' and 'The Big Breakfast', also revealed that filming 'Top Gear' is like nothing he has experienced before and compared it to a 'Bond' film.

He said: "I have never experienced anything in my career that comes close to what it's like to make a single film for 'Top Gear', let alone a whole hour show, let alone a whole series. There is nothing like it anywhere else in the world of TV.

"Every scene could be from a movie, every moment teetering on the brink somewhere between disaster and triumph. The vast majority of television I have been involved with in the past has been much more 'of the moment', more disposable if you like, as well as being usually live or 'as live'. All of which is so NOT 'Top Gear'. It's more akin to a 'Bond' movie. By the time each episode is broadcast, 95 per cent of its content will have been edited to within an inch of its life to be tighter, brighter and jump off the screen and down your throat."

The new series of 'Top Gear' launches on Sunday, May 29 on BBC Two.
