The Ferrari FXX won the Eyeson Design Award as the best example of functional design at the Motorshow of Detroit. Seventeen of the most renowned international designers, including Chris Bangle from BMW, William Davindson, head of styling at Harley-Davidson and Shiro Nakamura, from Nissan, sat on the panel. The judges awarded the prize as the FXX was the car that best "expresses the functionality of design as an instrument to reach the objectives for which the vehicle was developed". The FXX is a prototype destined to only 29 of the most loyal and passionate Ferrari clients. The project is part of a special collaborative technical programme between these clients and the Prancing Horse. The model is the most advanced granturismo produced at Maranello and is exclusively aimed at use on the track. It will form a crucial part of the ongoing research and development programme set up with this innovative group of 'client-test drivers'. The car is not homologated for use on the road and is not expected to compete in races.
