The revamped Top Gear is set to return next spring.
May 8 is the date pencilled in and filming has already started.
The episode of BBC Two's much-loved car programme will be the first since Chris Evans was announced as its new host.
This followed the departure of regular trio Jeremy Clarkson, James May and Richard Hammond.
Ferrari-loving Evans, 49, revealed the date on James Martin's Saturday Kitchen.
He said that filming will end three days before the 16-episode series is due to begin.
The US is among the locations where the show is being filmed.
Evans, who put 13 cars up for auction at last September's Goodwood Revival, did not say who his co-hosts would be.
Meanwhile, Top Gear's former hosts signed off their stage tour at the O2 arena in London on Sunday November 29.
Clarkson, May and Hammond have played to a total of 2.2 million spectators across 32 cities and 19 countries worldwide with their unique brand of motor-based mischief and mayhem.
The three-night O2 run included special guests in the shape of a Porsche 918 and a DB10 courtesy of Aston Martin, which was used by Daniel Craig's James Bond in Spectre.
Clarkson's dismissal from Top Gear in March followed a "fracas" with a senior member of the production staff.
He has since reunited in front of the cameras with his two former Top Gear colleagues to start filming for their new driving programme for Amazon Prime.
Portugal is reportedly one of the destinations featured on the show, which has an estimated £160 million budget.
