Series 10 features challenges that only the very brave - or the very stupid - would dare to undertake. For example, who in their right mind would attempt to drive through the Kalahari Desert in three 20-year-old bangers? Or try to cross the treacherous English Channel in a fleet of amphibious cars that are less seaworthy than the average church? The Top Gear boys of course. But Top Gear is much more than just three grown men - who should know better - larking about. There is some serious car journalism in here too, with exhaustive road tests of the latest models, a search for the perfect driving road in the Porsche 911 GT3 RS, Lambo Gallardo Superleggera and Aston Vantage N24, a look-back at the history of motoring, man versus machine experiments, and power tests featuring the world's most exotic supercars, including the Ferrari 599, Audi R8 and CaparoTL And, of course, there are all the tried and tested Top Gear favourites including the News; the Cool Wall and The Stig, who puts the rich and famous through their paces in the Star in the Reasonably Priced Car.
