Episode 1

An Aston DBS Volante, a Ferrari California and a Lamborghini Gallardo Spyder are driven by Jeremy Clarkson, Richard Hammond and James May respectively through Romania in search of tarmac that many hardcore drivers claim is the nothing less than the greatest road in the world.

On the Top Gear track, James compares two absurdly powerful limousines: the BMW 760i and Mercedes S63 AMG.

The programme also features Star Trek, Troy and Hulk star Eric Bana, who does a lap in the Reasonably Priced Car and is interviewed by Jeremy.

Episode 2

Jeremy, Richard and James attempt to save the planet by building their own electric car out of TVR chassis and milk float batteries. The electric car is then driven through the streets of Oxford, before being put through the rigours of the new car testing process.

The Top Gear track witnesses a battle of the continents. Representing the United States of America is the American Corvette ZR1, while Europe’s entry is the Audi R8 V10. What will prevail: American muscle or European finesse?

And the Star In A Reasonably Priced Car is Hollywood’s hottest new property: Michael Sheen, star of Frost/Nixon and The Damned United.

Episode 3

Jeremy Clarkson and Richard Hammond settle the thorny issue of which company has, above all others, made the greatest number of truly brilliant cars. They drive various models of Lancia cars through the British countryside and have a night race against a Morris Marina.

James May has a novel solution for getting caravans to campsites without clogging up the roads by taking the helm of a caravan airship whilst being followed by Richard Hammond in a Lamborghini Balbonne.

Jeremy hits the track in a remarkable replica of a Lancia Hawk Stratos. Chris Evans (TV broadcaster, DJ of BBC Radio 2’s Breakfast Show and all-round petrolhead) is this week’s Star in the Reasonably Priced Car.

Episode 4

Jeremy Clarkson travels to Belfast to conduct an extremely thorough test of the Renaultsport Twingo 133, involving a tunnel, a ferry and actor Ross Kemp.

Meanwhile, Richard Hammond investigates ways to speed up your next summer holiday through the medium of motorsport and invents the brand-new sport of airport vehicle racing. Various airport municipal vehicles (including a fire engine, baggage carrier and hospitality lorry) race around an airfield. Jeremy compares 4x4s, testing a Diesel Range Rover, BMW X5 and Audi Q7 on the Top Gear track. And the Star in the Reasonable Priced Car is the award-winning British film director and Madonna’s ex-husband, Guy Ritchie.

Episode 5

Jeremy Clarkson, Richard Hammond and James May attempt to prove that cars can be art by taking over an entire modern art gallery and filling it with motoring-related works, including some remarkable creations of their own.

Formula 1 racing driver David Coulthard assists Jeremy in creating a painting using the Red Bull F1 car exhaust and infra-red paint; James builds a sculpture from car parts; and Richard paints an homage to John Constable’s The Haywain with a motoring twist.

In their quest to prove that cars can be more popular than traditional art, the presenters set themselves the challenge of attracting more visitors to their exhibition than will visit a more traditional gallery over the same period – a task that forces them to engage in some unusual promotional activities, including a visit to Middlesbrough Football Club.

On the test track, Jeremy drives a new British supercar, the sensationally fast and sensationally expensive Noble M600. And The Star In The Reasonably Priced Car is Formula 1 Champion racing driver, Jenson Button.

Episode 6

Undaunted after their epic adventures across Botswana, Vietnam and The Arctic Circle, the Top Gear presenters embark upon another eagerly awaited special challenge, and without doubt this is their toughest and most exciting yet.

Jeremy Clarkson, Richard Hammond and James May are dropped deep in the Bolivian rainforest armed only with three shabby 4x4s which they bought from the local small ads for a maximum of £3,500 a piece. What follows is set to be their most extraordinary journey to date as they attempt to drive from the heart of Bolivia to the Pacific coast of Chile.

After facing the challenge of getting the vehicles onto dry land, they make their way through the jungle, trying to escape from the deep, dark centre of the rainforest by crossing gullies and rivers. They finally emerge, only to encounter drug lords, the debilitating effects of high altitude in the Atacama Desert and the terrifying sheer drops of the infamous El Camino de la Muerte (aka ‘Death Road’), where they are literally pushed to the edge.

The final hurdle is a range of impossibly steep sand-dunes as, battered and exhausted, they make their way down to Chile’s Pacific coast.

Episode 7

Jeremy Clarkson makes a film about the BMW X6. Despite being told by the producers to keep to a budget, he takes the car to test in all corners of the globe and ends up conducting one of the most expensive road tests in Top Gear history.

Richard Hammond puts the £340,000 Lexus supercar to the test on the Top Gear track, and James May drives the new Vauxhall Insignia VXR, accompanied by Margaret Calvert, the designer of Britain’s road signs.

It is also time for the annual Top Gear Awards ceremony, and the atmosphere is electric as the winners are announced, including Injury Of The Year and Car Of The Decade. The Star In A Reasonably Priced Car is American blues musician Seasick Steve.
