Guy Martin is back to push the boundaries of the science of speed.
As always, Guy will be recruiting the very best of current day British engineering talent to provide plenty of knowledge and help in his mission. But will he succeed?
Guy goes head to head with Formula One legend David Coulthard to see if a F1 car has the edge over a Moto GP bike in four break-neck challenges.
Guy will also try and cross the channel in a human-powered airship that he'll design and try to race the fastest human-powered boat and he will race his customized Transit van in the fastest road-race on the planet; the Nevada Open Road Challenge
