In this episode Fifth Gear re-unites two of the greatest names in Formula 1 history – Prost and Senna. This time it’s Ayrton’s nephew Bruno and Alain’s son Nico who will do battle on the track. With Tiff Needell and Karun Chandhok in attendance they set out to discover which of a current crop of hot hatches is best. It’s a knockout competition that will eventually result in just two cars racing head to head around the Snetterton circuit. And that means one thing – it’s Prost v Senna all over again. After nearly 60 years the greatest 4x4 in the world, the Land Rover Defender, is about to go out of production. Vicki Butler-Henderson celebrates the end of an era by taking part in a high speed off-road challenge against current Defender Challenge Trophy champion, Edd Cobley.
