With extraordinary access to one of Britains's most secretive companies, this BBC documentary shows how Formula One racing team McLaren is now building the McLaren MP4-12C road car using some of their F1 technology.

The program goes inside the McLaren factory, meets the team of engineers and boss Ron Dennis. F1 racing drivers Jenson Button and Lewis Hamilton share their opinions of the car and there is a look at the brand new McLaren Production Center.

During the 1-hour show we discover how the car has been designed, tested and built from scratch, including its unique carbon fiber "monocell" technology and its turbocharged v8 engine -- the first the company has ever built.
