In the first show of the new series, Chris Evans takes the Dodge Viper ACR to the home of Topballoon in Nevada, to battle Sabine Schmitz in a Chevrolet Corvette Z06. Matt LeBlanc tackles wildest Morocco in Somerset's finest off-roader, the Ariel Nomad.

Back on British soil, Evans and LeBlanc take a rather soggy road trip to Blackpool in a pair of roofless Reliant three-wheelers, whereupon they are tasked with defending the honour of their nations in a series of gruelling UK-versus-USA challenges.

Back in the studio, this week's celebrity guests are Social Network star Jesse Eisenberg and Gordon Ramsay.

Top Gear Show Summary

BBC's hit motoring show is more than just a show to review new cars. Top Gear is essential viewing. Not just for petrol heads, it also has a huge following amongst people with little or no interest in cars - both male and female. This is due to the show's irreverent approach to motoring, the humour and the priceless chemistry between the show's presenters - Jeremy Clarkson, Richard Hammond and James May, with special appearances from the tame racing driver, The Stig.

Don't be fooled, this is not another boring technical car programme, there is carnage, mayhem and fun, with less stuffy mundane car reviews. The boys have races and do crazy things with cars - anything from driving them into swimming pools to setting them on fire!
