The host of the hit BBC One nature show has called for bosses to make a cross-over episode of the two programmes, amid continued criticism of the rebooted motoring series.
Speaking to PA, Adam said: "It would be lovely to take some celebrities out of London and take them on a tour of the countryside to show them what it's all about.
"I think we should get a load of tractors on 'Top Gear' with Chris Evans - I'd love to do that."
Chris' version of 'Top Gear' has received a negative reception from fans since it launched last month, and has also struggled in the ratings, with last week's show hitting a 10-year low for the series, when just 2.4 million tuned in.
'Countryfile', on the other hand, regularly attracts around seven million viewers, even beating 'The X Factor' on occasion when the two shows aired against each other last year.
So it seems if Chris is looking to boost Top Gear's viewing figures, a cross-over with 'Countryfile' may not be such a bad idea.
Speaking to The Mirror, he said: “I’m a big fan of what [Clarkson] did in the past but I have to be honest and tell it like it is.
“Jeremy and the other guys had a very successful past but the point is - it is in the past and Jeremy is past it when it comes to ‘Top Gear’. His time has come and gone. There has been too much time spent focusing on them - but it was a very different show then.”
Clarkson, Richard Hammond and James May are set to unveil their own new project, ‘The Grand Tour’, which will begin streaming on Amazon Prime in the autumn.
