The Ariel Atom, with a V8 engine, 900 bhp per tonne and a 0 – 60mph time under 2.3 seconds, is driven on the track by… James. Will it reach 60mph? Richard plays with a Porsche – again. This time, the new 911 Turbo S Cabriolet, which he races against a VW Beetle. A race with a Top Gear twist… Jeremy drives a practical car that you can afford – the Skoda Yeti. And puts it through some rather unusual tests. John Bishop is the Star in a Reasonably Priced Car.
