Seeking to help encourage trade with India, despite (the then) British Prime Minister David Cameron wishing they won't, the boys head out and see if they can promote British goods to the Indian public, each taking with them a British car that they hope will help with the job – May chose the luxury of a Rolls-Royce Silver Shadow, Clarkson opts for the stylish Jaguar XJS, and Hammond takes the classic Mini Cooper. On their "trade mission", the presenters attempt to speed up Dabbawala delivery in Mumbai with little success, bring motorsports to Jaipur with a hill-climbing event, host an ambitious but rubbish trade fair in Delhi, before modifying their cars for a trek up into the mountainous, Himalayan region of Himachal Pradesh and their final destination of Shipki La.

Clarkson and May head to China to explore the country's merging car industry in response to the assertion that everyone will be driving Chinese cars in five years, where they encounter facsimiles of popular car designs from other countries, discover how the automotive populace exploded in size, and meet with The Stig's rather aggressive, Chinese cousin. Elsewhere, Hammond explores the world of NASCAR by travelling to the Texas Motor Speedway for the AAA Texas 500 and interviewing some notable NASCAR drivers. The Mercedes-Benz SLS AMG Roadster is given a slidey review by Clarkson on the test track, and former Friends star and car lover, Matt LeBlanc, is in the hot seat of the Kia Cee'd.

Believing they could make great car chases for movies, Clarkson and Hammond are invited to provide assistance in directing one for the remake of The Sweeney. Working alongside the film's stars, Ray Winstone and Plan B, Clarkson attempts to prove that dynamic camera usage and timed moves are what can make a good chase sequence, while Hammond tries to show that it should have exciting (if unrealistic) stunts including car jumps. Meanwhile, May takes a look at the Vauxhall Corsa VXR Nürburgring Edition and the new Fiat Panda on the track, and Ryan Reynolds is the latest star going fast in the reasonably priced car.

As a final tribute to the sixty years of production that Saab has performed before its closure, Clarkson and May look back at some of the bad ideas the company made, and some of the very good ones they made, including how much emphasis they put on the safety of a car's occupant. Meanwhile, the Maserati GranTurismo MC Stradale and the Mercedes-Benz C63 AMG Coupe Black Series are tested by Clarkson out on the track, Hammond sees if Finnish world rally driver, Toni Gardemeister, can beat Yves Rossy, the world's first jet propelled man, in a Skoda Fabia S2000 around an eight-mile special Welsh Rally Stage (episode from "At the Movies" DVD Special), and Eleventh Doctor, Matt Smith, swaps the TARDIS for the Kia Cee'd.

The presenters head out to Donington Park to test out three stripped-out track cars – May believes it cannot be anything other than the Caterham Seven, Clarkson opts to show that it is the KTM X-Bow, and Hammond attempts to prove that it has to be the Morgan Three Wheeler. Along with a series of challenges on the Park's circuit, the trio also see how practical they are as everyday cars by using them to drive to work. Elsewhere, Clarkson re-enacts the 'Battle of Britain' at the Track as a modern recreation of a classic 1920s Bentley model, faces up against the fury of a home-made German car, Brutus, while Alex James of Blur takes to the track with the Kia Cee'd.

The trio show that you can have more fun by doing Rallycross motor racing for the same amount of money you could spend playing golf, with Clarkson racing in a BMW 328i, Hammond a Citroën Saxo VTS, and May a Toyota MR2. Elsewhere, Hammond takes a look at the new BMW M5 at the track, May gets his chance to see his childhood dream car, the £5.6 million Ferrari 250 GT California, at Chris Evans' garage, while Kimi Räikkönen talks about his return to F1 before taking out the old Liana on the track, and Guns N' Roses guitarist Slash shows how good he is the current reasonably priced car.
