Jeremy test-drives the Focus RS, Jason outlines some great deals on the Citroen C5 & Rover 75, and Richard gets a dream come true, driving a Escort RS 1800. Later on, the brand new Noble M12 is track tested, and Hammond finds out how many motorcycles a double-decker bus can jump over. We also see Jay Kay, the Jamiroquai frontman, as the Star in a Reasonably Priced Car.

CHALLENGE: Fastest political party

Jeremy drives the new Rolls Royce and there’s a nostalgic look at the Rover P5, including one owned by the Queen. Jamie Oliver tries his luck in the Liana as the Star in a Reasonably Priced Car, he also tries to prepare a salad in his camper van, whilst being driven around the track by the Stig. On the track, politicians representing the main political parties, as well as some less well-established parties try to become the fastest political party.

Jeremy Clarkson, Richard Hammond and James May immerse themselves in nostalgia and try to prove that hot hatches from their younger days are better than today's equivalents. Jeremy grabs the keys to a Volkswagen Golf GTI, Richard takes the wheel of a Vauxhall Nova SRi and James May opts for the Ford Fiesta XR2i, and the trio set off on a road trip that includes a hill climb and a visit to a supermarket. However, their adventure concludes at an army training ground in Wales, where they and their steeds must face the heavily armed Top Gear Police Department. Downton Abbey star Hugh Bonneville blasts the Reasonably Priced Car around the test track.

Richard Hammond gets behind the wheel of the mid-engined Alfa Romeo 4C on the shores of Lake Como in Italy - but his enjoyment of the lightweight vehicle is disturbed by the arrival of Jeremy Clarkson, who demands a race against his quad bike. Jeremy also visits Belgium, putting the McLaren P1 hypercar to the test in Bruges and around the Spa-Francorchamps Formula One circuit - and its combined power output of more than 900bhp generated from electricity and turbocharged petrol V8 power is likely to cause astonishment. Meanwhile, James May spends time at Camp Bastion in Afghanistan to learn about the army's vehicle redeployment efforts, and Thor star Tom Hiddleston tries to coax the best time he can muster from the Reasonably Priced Car.
