Four months after Richard's 'upside down' thing, Top Gear returns. To get things going the Jaguar XKR is compared to the Aston Martin V8 Vantage. After spending so many years zooming along the roads of Britain, the lads turn their hands to mending them by trying to do a week's worth of roadworks in 24 hours.



Also, the 288mph jet car crash which left Richard fighting for his life in September 2006, a crash from which he has made a complete recovery - hurrah!



Jamie Oliver is the Star in a Reasonably Priced Car.

The lads try to play golf - the game which pervades exclusivity and stupid trousers - whilst testing the Audi TT, the Alfa Romeo Brera and the Mazda RX-8, three coups in the 20,000 - 25,000 price range.



James, in an attempt to bury his Captain Slow persona, attempts to take the Bugatti Veryron up to its maximum speed of 253 mph (407km/h) at Ehra-Lessien - Volkswagen's private test track.



Hugh Grant is the Star in a Reasonably Priced Car.

In this 'American special', Jeremy, James and Richard are on a fly-drive holiday with a difference. Instead of hiring a car, each has to buy a car for no more than 00. Starting in Miami, they travel through Mississippi and Alabama - where they manage to upset the locals - and end their journey in New Orleans.



As usual, there will be some Top Gear challenges along the way; a dead cow, prostitute-obsessed truckers and a meeting with Fat Stig - Stig's American cousin.

Another day, another Porsche, but will Jeremy be able to tell the difference between this new 911 Turbo and the old one? He also drives the Brabus S Biturbo Mercedes SL which has a staggering 730bhp. James and Richard try to turn a Reliant Robin into a space shuttle. One small step for a small man etc...



Simon Pegg is the Star in a Reasonably Priced Car.

In response to recent criticism regarding speed, Top Gear presents to you - and I hope in particular, the Scottish Green Party, the Lamborghini Murcielago LP640. That's that criticism dealt with then.



They get through a fair amount of petrol on Top Gear, so in an attempt to find an alternative source of fuel, The Captain, Brokeback and cuddleer go green - slightly - and attempt to 'grow' their own fuel. The sight of tractors on the Top Gear track will undoubtedly delight and confuse in equal measure. The chance of a small fire is also quite likely.



Also this week, Jeremy makes a public information film: this involves crashing a train into a people carrier - a French people carrier. It might not have the same effect as the public information films from the 1970s, but at least the clothing will be authentic.



To the absolute delight of Jeremy, Kristin Scott Thomas is the Star in a Reasonably Priced Car.

The perfect British hen night: A fat girl with a tattoo; her drunken friend with those little devil ears molesting a male stripper, 'L' plates, copious vomiting and of course - a stretch limo. But why hire one when you can make your own? Step forward the Top Gear boys who do just that. Once built, they use their stretch limos to ferry the 'stars' to the Brit Awards.



On the track, two Ford Mustangs: one tuned by Shelby and the other by Roush. Have the Americans finally built a car that deserves more than pointing and giggling from smug Europeans?



Billie Piper shows off her driving skills and her brand new accent as the Star in a Reasonably Priced Car.
