For the cover story of the December issue of Motor Sport we managed to get Formula 1 designer Adrian Newey into two of his cars.

Here’s the film of our day at Silverstone with the Leyton House CG901 and Red Bull RB6. David Coulthard – who took 10 of his 13 Grand Prix victories at the wheel of Newey-designed cars – takes us through proceedings and waits with hang-wringing team principal Christian Horner while one his team’s most precious assets hares around in an F1 car.
