James May admits Jeremy Clarkson "drives him nuts" on 'The Grand Tour'.
The 55-year-old TV presenter is preparing for the new series of the popular online motoring series - which he co-hosts alongside Jeremy and Richard Hammond - and claims Jeremy, 58, has really limited practical skills.
Speaking to The Daily Telegraph newspaper, James said: "Hammond, he's much more ... useful. Jeremy can't do anything. I've never discovered anything he can do.
"I mean he can drive a car round a race track pretty well, but he wouldn't be able to light a fire - I know this from experience.
"I don't think he'd be able to cook anything, he can't put a tent up, he's not in any way practical.
"He drives me nuts. I would say Jeremy is the most conservative of us, and he's the most establishment. Despite his reputation for being anti-establishment, he's actually probably part of it. He's the enemy."
James also confessed he thinks Freddie Flintoff and Paddy McGuinness were a "radical choice" for presenting the upcoming series of BBC's 'Top Gear' - which the trio hosted before their exit in 2015 - following Matt LeBlanc and Chris Evans leaving the show after it suffered poor ratings.
But James admitted the new additions could be a "clever" move.
He added: "A cricketer and a comic. I'm really keen to see what they do with the new guys, because it's quite a radical choice.
"They may have been extremely clever because [Chris] Harris is a proper nerd: he races cars, and he buys and sells cars; he knows his stuff."
'The Grand Tour' has been renewed for a fourth season which will see the trio "moving away from cars" and instead going on big road trips across the globe.
James said: "We're turning it into a sitcom. The focus has been gradually moving away from cars for quite a long time, to be honest.
"I think in the future we will be seen as more of a travelling adventure programme."
The new series of 'The Grand Tour' launches on Amazon Prime Video on January 18th.
