Now for the first time in HD, Series 14 of the world's biggest car show takes to the skies as James makes a DIY airship — out of a caravan. Back on the ground, Richard races a fleet of airport machinery down a runway to solve the problems of air travel. Then, in their biggest adventure yet, the boys venture into the Bolivian rainforest armed only with a few heavily used 4x4's, where they face such challenges as the aptly named "El Camino de la Muerte" — otherwise known as the "Road of Death." Will they survive? Meanwhile, the Stig is loose on the track in the Audi R8 V10, the Mercedes SLS, and the Lexus LFA. Don't miss the boys trying their hand at art, getting "green," and Jeremy taking his Renault Twingo for a swim in the most action-packed series of Top Gear yet!
