the first half of the 2011 Formula 1 season. What’s more, the Red Bull RB7 is unique. Whilst every other car on the grid started out with a click of a CAD screen, the RB7 started its life as a hand-drawn design on a piece of paper in Adrian Newey’s office in Milton Keynes, England.

‘Whether you use a CAD system
or a drawing board, ultimately it’s a way of taking thoughts from in your head, putting them into a medium, developing them in that medium and then communicating it with others,’ explains Newey, the chief technical officer at Red Bull Racing. ‘It’s almost like a language, and what system you use is personal preference. But it is fair to say we couldn’t realistically cope with many people in the company using drawing boards!’
