Arguable the best Aerodynamicist F1 has ever seen, Adrian Newey was born on Boxing Day. He cut his Formula One teeth under Harvey Postlethwaite at Fittipaldi F1 and enjoyed a brief and successful stint designing for the Indycar and CART championships. Back in F1 he won constructors championships for Williams and McLaren and has vastly improved the Red Bull team from also-rans to race winners. Weekends off are a bit of a busman's holiday for Newey - he likes nothing better than to slip behind the wheel of one of his vintage or classic race cars. He has also competed in more modern machinery in endurance races - including the Le Mans 24 hours.
