The Show - Next Episode

On the next episode of Top Gear, Clarkson gets used for target practice, a twin-turbo Porsche takes on an envelope and the fastest man on earth drives a reasonably slow car.

Thus far, the British Armed Forces have deployed an Apache Gunship, a Challenger Tank and even a squad of elite snipers in an attempt to put big holes in Jeremy. This week they're returning to do their duty for Queen and country and they're bringing along a brace of their latest cutting-edge toys.

Richard and James will be discovering if the brand new 493bhp Porsche Panamera Turbo can get from one side of Britain to the other faster than a letter delivered by the Royal Mail. This might sound slightly one-sided but fortunately the postal service isn't just about little red vans and squeaky bicycles.

Back in the studio, Olympic gold-medal winning sprinter Usain Bolt will be chatting to Clarkson and attempting to prove he's faster than a small man with a big hat by taking a crack at Jay Kay's all-conquering lap time.
