B is for BBC. The broadcaster who makes the show and, through its commercial arm, has sold the programme to over 150 territories globally. In addition the BBC has managed to sell the Top Gear format to be remade in a number of countries, including the US, Australia, Russia, China and Korea.
C is for Cars. It's not very imaginative, I know... but there are quite a lot of them on the show. I suppose you could have Clarkson and controversy too - it's not often you'll see those two words in the same sentence... Oh go on then, here are some of his best gaffes.
D is for Dunsfold Park - the aerodrome near Cranleigh, Surrey, where Top Gear is filmed in a converted aircraft hangar. The adjacent runways and taxiways are used as the main test track.
E is for Enstone - the Oxfordshire village where Top Gear hoped to relocate filming to in 2006. However, the plans were scuppered when the local authority rejected planning permission to use a nearby airfield as a test track on environmental grounds.
