The fast, open nature of Silverstone requires both engine power and good aerodynamic performance. But as we saw during Friday practice, the changeable weather, particularly the wind, can make the right setup a moving target.
With the 2014 cars having more torque and less grip, getting the cars right for Silverstone is a new challenge. Running high downforce, the cars are pressed hard against the track and need a stiff set up to keep the underfloor off the ground.
But the slow parts of the lap mean the cars still require good mechanical grip, especially in the rain.
