Why is aerodynamic efficiency key at Silverstone?
Silverstone is renowned for its super high speed corners that populate the first half of the circuit. These demand optimum aero efficiency and a stable balance; this allows the drivers to attack the fast corners and get a good lap time. In addition, it is essential to have good mechanical grip for the latter part of the track; so whilst the aerodynamic performance is vital, so is a compromise with the set-up. At the 2006 race, the lap times around Silverstone were faster despite the use of V8 engines. Will the control Bridgestone Potenzas have any effect on lap time this season? At the race last year, the cars had more grip because of the use of softer tyres, and this meant that despite the V8 engines, lap times were faster and the cars were quicker in the corners. The Bridgestone Potenza tyres are not as soft this year, and as a result, the cars carry marginally less speed through the corners, particularly at the start of the track. However the difference from 2006 to 2007 will not be
