In a brand new challenge, Guy Martin has completely remodelled his beloved Transit van to take on one of the world's most iconic speed records. Three years ago, Guy crashed that favourite Transit on the way to work - and wrote it off. He was gutted, but rather than letting it go to the breaker's yard, Guy rebuilt his van as a blisteringly fast racing machine, which he raced across the Nevada desert at speeds of up to 165 mph. Now, Guy's on a whole new mission with his favourite van - he wants to break the van lap record at the Nürburgring in Germany - the most demanding, difficult and dangerous motor racing circuit on earth. It requires a total rebuild of the van, a job Guy undertakes in his own shed and which takes over his life for 5 months. It requires him to learn the 100+ corners of the 12.9 mile Nürburgring circuit and everything needs to go perfectly for the single hour that he has the legendary circuit to himself for his record attempt. It's a massive undertaking which repeatedly pushes Guy and his van to their limits and, as it approaches its climax, threatens to end in disaster.
