The Grand Tour travelling tent arrives Stuttgart, Germany, the home of Porsche and Mercedes-Benz. In this show, James May takes the new Honda NSX supercar to the Eboladrome to push its cutting-edge hybrid technology to the limit and Richard Hammond immerses himself in the world of doomsday preppers as he constructs a 'bugout' vehicle that will allow him to survive a bleak future of nuclear winters, alien invasions and massed herds of zombies. Meanwhile, in a less realistic attempt at engineering, Jeremy Clarkson invents a new kind of fashionable SUV. Also in this show, the hosts attempt to meet the future demands of electric cars by harnessing power from the currently untapped actions of everyday life.
