In "Hot Metal", Jeremy Clarkson tells us how everything is slowing down. But is it the same for today's cars? That means the 200-mile-per-hour Jaguar XJ220 taking on a Pagani Zonda. It means pitting a Mercedes McLaren SLR against a Porsche Carrera GT. And it means lining up a Ford GT with the original GT40. The Aston Martin DB9 is here too, taking on the old V8 Vantage warhorses, and just how much faster is the Mitsubishi Evo 8 compared to the first Evo? And just for the hell of it, a Nissan gets riddled with machine gun fire while taking up the new and dangerous sport of 'clay car shooting'!
