Another epic race pits the car against public transport. Richard and James travel by aeroplane and train in an attempt to beat Jeremy, who is driving a Ferrari 612 Scaglietti to their destination at Verbier in Switzerland.
In Lillehammer, Richard and James are having another race with the help of the Norwegian Olympic Bobsleigh team: Richard tries to race down the bobsleigh track at Lillehammer, faster than James can travel down the road that runs along side the bobsleigh track. James is in a Mitsubishi Evo rally car driven by Henning Solberg.
Stig gets to take a F1 Renault around the track and old racing cars compete with modern road cars to see how fast they are. Eddie Izzard is the Star in a Reasonably Priced Car.
Richard takes the new Mustang on a road trip along Britain's straightest road to Lincoln. The Prius, a supposedly eco-friendly vehicle, is driven by Jeremy who thinks that a diesel Lupo will actually do more miles per gallon - 75mpg - compared to the 45mpg of the Prius.
The Lamborghini Murcielago is up against the Mitsubishi EVO VIII and the Top Gear Awards are announced.
Roger Daltrey is the Star in a Reasonably Priced Car.
Richard, James and Jeremy are set a challenge to buy a working Porsche for a maximum of £1,500. Richard buys a 924 (the one with the van engine) for £750, James a 944 for £900 and Jeremy - predictably a 928S for £1,500. They are then set a series of challenges to see who has bought the best car.
Jeremy also drives the new Golf GTI and described it as a sensation (even though it weighs the same as "South Africa").
A Mini is featured in Restoration Rip-Off and Billy Baxter, a blind man, tries to set a faster time in the Liana than Richard Whiteley and Terry Wogan.
Cliff Richard is the Star in a Reasonably Priced Car.
Richard drives the new 218mph, £400,000 Pagani Zonda Roadster in Switzerland - one of only 40 versions of the car that will be built. He compares it to the Wally 118 - a £14 million pound boat made carbon fibre.
There's a game of Caravan Conkers between Richard and James; they also spend 24 hours in a Smart car. This is because the makers described the interior of the car as 'lounge concept'. Unable to leave the car, they spend the night parked in the Screaming Woods in Pluckley, the 'most haunted village in England'. The village 'boasts' 12 ghosts including the Highwayman, the Screaming Man and a monk.
Jeremy drives the new Aston Martin Vanquish S and the Ferrari 575 with a little help from Steve Coogan.
Richard drives the new Ford Focus and compares it to its rivals. Pink Floyd's drummer, Nick Mason, lends Jeremy his new Ferrari F60 Enzo in return for a subtle plug for his new book. There's a race between a grumpy teen on an all-terrain board and a Mitsubishi Evo7 Group N rally car - and a Bowler Wildcat just for good measure. Ben Collins drives the cars.
Jeremy compares super cars from the 1980s with their modern counterparts to see if the more modern up-to-date cars really are better. The Pagani Zonda, Porsche Carrera GT, Ferrari Enzo are the modern super cars and the throw-backs are the Jaguar XJ220, McLaren F1 and the Ferrari F40.
Geri Halliwell is the Star in a Reasonably Priced Car.
Cars from the "colonies": the Vauxhall Monaro VXR from Australia and the Chrysler 300C from the United States take on the Jaguar S Type R on the beach at Pendine Sands in south Wales. Back at the Top Gear track, Jeremy is trying to tell the difference between the old Porsche 911 Carrera and the new Porsche 911 Carrera S.
That could be the least of Jeremy's worries, in the last series after looking at the prototype of the new Astra, he said he would eat his own hair if the car actually looked like the prototype when it was launched. With a guest appearance from chef Antony Worrall Thompson in the studio, things aren't looking good for Jeremy.
There's also time to destroy an ice-cream van and some bouncy castles and Bill Bailey is the Star in a Reasonably Priced Car.
