Am I reading the rules correctly here,
The reason why Renault have a small gap between their front wing flap and the nose cone is that the FIA stipulate a 250mm distance between the cars centre line and the start of the flap. A wide nose reduces this gap as the space is taken up with the cars hooter.
3.18 Driver adjustable bodywork :
A single closed section situated each side of car centre line in the volume bounded by :
- lines 450mm and 800mm in front of the front wheel centre line ;
- a vertical plane which intersects these lines at a distance 250mm from the car centre line.
