Crash Testing a Renault Megane

The astonishing 655bhp Koenigsegg CC8S arrives at the Top Gear test track, setting a blistering straight-line speed and raising the question of whether it can also claim the fastest lap. Jeremy Clarkson samples the enormous Hummer H2, while Richard Hammond takes an even less sensible approach to transport by driving a Talon riot-control vehicle straight through a portacabin . Elsewhere, the Renault Mégane undergoes a crash test with a very real occupant, the new Aston Martin V8 Vantage makes its debut, Stuart Hall champions the Rolls-Royce Silver Cloud as the greatest car ever made, and Neil Morrissey is the Star in a Reasonably Priced Car.
