The area in front of the rear tyres is a crucial focal point for all teams this year as they look to improve rear-end aerodynamics, and in the last few races we have seen many different solutions. For the Marina Bay race Ferrari multiplied the slots in the floor (highlighted in yellow), from three to nine. In addition they added two fins (red arrow) on the sides of the deformable rear crash structure, as Mercedes did in Spain. The car, with its strong rear end, is much more to Sebastian Vettel’s liking now, hence the improved performance.
