Series 13 of this BAFTA-winning show skids, roars and explodes its way back onto DVD, with man versus machine experiments, exhaustive road tests of the latest models, a look back at the history of motoring, weekly power tests featuring the worlds most exotic super-cars and a surprise revelation. James goes for a ride with stunt-driving legend Ken Block; Jeremy and James attempt to understand what makes a great Volkswagen advertisement and then try to film one of their own. Rather predictably, it doesnt go well. And in a television-first, the mysterious Stig takes off his helmet to reveal just who he really is.
