The Top Gear boys are once again let loose in the USA, this time for an epic road trip up the east coast. Jeremy Clarkson, Richard Hammond and James May are comparing the Mercedes SLS, the Porsche 911 GT3 RS and the Ferrari 458 Italia. Along the way they undertake a series of challenges culminating in a fight to find the fastest way into New York, all in the name of crowning the world's greatest sports car. There's a round up of car-related Christmas tat and Oscar-winning film director Danny Boyle takes to the track as the star in a Reasonably Priced Car.

Richard road tests the new Volkswagen Touareg as well as having race against two snowmobile racers in a customized Volkwagen Touareg (the one used in the Dakar Rally). James tests the new Buggati Veyron Supersport and attempts to take it to its top speed of 258mph. Jeremy documents the life of the legendary racing driver, Ayrton Senna with interviews from racing drivers who raced with him to the those who were huge fans of Ayrton Senna as well as looking back at archive footage from past races to see what made him the greatest racing driver of all time. Tom Cruise and Cameron Diaz are the Stars In A Reasonably Priced Car.

The boys build motorhomes before setting off for a bank holiday weekend in the West Country to see how each of their creations performs in the real world. Meanwhile, Jeremy is also at the track to test the new Audi R8 V10 Spyder against the latest version of Porsche's enduring 911 Turbo cabriolet. Plus, Andy Garcia takes his turn as the Star in the brand new Reasonably Priced Car.

Jeremy Clarkson, Richard Hammond and James May test the Aston Martin Rapide, the Porsche Panamera Turbo and the Maserati Quattroporte as they attempt to find the world's greatest four-seat supercar. After an early morning start in the City of London, the boys embark on a road trip across the south of England, stop off for a race around a closed-off business park, and end up undertaking a rather special chauffeuring job. Meanwhile, Richard is on the test track in two very different muscle cars, the Chevrolet Camaro SS and Mercedes E63 AMG. And there's a double dose of celebrity as Harry Potter star Rupert Grint and F1 ace Rubens Barrichello take their turns as the Stars in a Reasonably Priced Car.

Jeremy Clarkson, Richard Hammond and James May attempt to find a trio of cars which are equally at home on the race track as they are transporting a family to the shops, for a budget of 5,000 pounds. They end up with a BMW M3, a Mercedes 190E and a Ford Sierra Cosworth which they put through their paces in Europe's home of speed, Germany. Plus James makes a rare visit to the Top Gear track to test a pair of Porsches - the 911 Sport Classic and Boxster Spyder - and Alastair Campbell is the star in the all-new reasonably priced car.

Jeremy Clarkson, James May, Richard Hammond and The Stig return for a new series of Top Gear. To investigate the reasons behind the lack of three-wheeled cars on the market Jeremy Clarkson gets behind the wheel of a Reliant Robin. James takes the Toyota Hilux for a final challenge, a nice little spin up an active Icelandic volcano. Meanwhile Richard gives the reasonably Priced Car a lovely send off and The Stig has a go in the new Bentley Continental Supersports.
