Former Blue Peter presenters John Noakes and Peter Purves are reuniting after 27 years for the Five programme
Britain's Worst Celebrity Driver Live.
They will attempt to drive from John O'Groats to the English south coast, while undertaking a series of tests for the cameras.
Purves, 66, and Noakes, 71, shared the screen on Blue Peter for more than 10 years until 1978, along with Valerie Singleton.
The motoring reality show will also feature other so-called "celebrity drivers" including actor Brian Blessed, former Chips star Erik Estrada and BBC Radio 1 presenters JK and Joel.
The celebrities will compete against each other to avoid landing the title "worst celebrity driver".
The series starts on September 11 and will be broadcast from a different city each night, viewers will vote of their least favourite drivers.
Five's Alex Sutherland said: "With these shows we're taking the successful 'Britain's Worst' brand and giving it an additional twist - the 'road movie' element and the excitement of 'live'."
