Arguably two of the coolest cars ever built seen here driving aggressively around Silverstone circuit. The McLaren F1 GTR is powered by a BMW V12 engine and this particular car is owned by Nick Mason. The 911 GT1 (996) is powered by a flat six and produces some mad flames as can be seen in the video. Both cars are incredible machines and it was an honour to see them on track at one of motorsport's most revered circuits.
