The last-ever episode of Jeremy Clarkson’s hit show The Grand Tour airs on Friday.

For their final trip titled The Grand Tour- One For The Road Mr Clarkson, James May and Richard Hammond drive across Zimbabwe in cars they have always wanted to own.

Mr Clarkson roars along the banks of the Zambesi in a customised Lancia Montecarlo, James May in a Triumph Stag and Richard Hammond in a MK1 Ford Capri RS3100.

The trio have worked together for 21 years altogether on the BBC show Top Gear and Prime Video's The Grand Tour since 2016.

The show has all the usual scrapes, breakdowns and banter with James May saying he will delete the others' numbers when it finishes.

Mr Clarkson has said he felt “surprisingly unemotional” when he filmed the final episode.

He said: “I’m not saying this in a derogatory way by any means but James has the emotions of a stone.

“He just doesn’t do emotions, so there were no tears from him. Hammond, yes.

“I was surprisingly unemotional in a weird way because I can see James and Hammond any time I want to, they’re only a phone call away, and I’m sure we will.

“And I’ve done enough of the travel, I was worn out by it.”

He added that he “would have been emotional” with the crew but they work on his Prime Video show, Clarkson’s Farm, where he attempts to run Diddly Squat Farm in Chadlington.

Punters have also been advised filming is going on at his new pub The Farmer's Dog near Burford.

Mr Clarkson said: “There I was with all these guys that I’ve known and worked with for 24 years and I said, ‘I’ll see you all on Monday morning’ because they all work on Clarkson’s Farm.

“I’m 100% convinced I would have been a lot more emotional without the farm show.”

He also said that amid wars in Ukraine and the Middle East, it is more difficult travel as the world is a “much more troubled place than it was 20 years ago”.

Mr Clarkson also called travelling a “young man’s game”, and said he “dreads” going into a retirement home but, aged 64, he does “fear it’s coming”.

Mr Hammond said there were “a lot of tears” at the end and he would miss “them terribly”.

He added: “We’ve seen each other in jungles covered in leeches, exhausted and grumpy in tents and boiling heat, elated in the most beautiful cities in the world.”

James May agreed they “will miss each other” including him “going on about things”, and them “pulling me up about it”.

He also said: “In the end we got to the point where we said, ‘No, we must stop whilst we’re still vaguely ahead. We mustn’t keep going until we embarrass ourselves’.

“It’s odd. I have mixed emotions about it. I will miss the adventure and the experiences and the craic and the ‘bantz’ and all that stuff.

“I won’t really miss the stress of it because I’m old now and a bit frail compared with back then.

"I don’t know what to do next, but it’s a nice thing to look back on and think, ‘we did that’."

The Grand Tour: One For The Road launches on Prime Video on Friday September 13.
