MERCEDES BARGEBOARD DEVELOPMENTS
When you look at a Formula 1 car going through the corners and bouncing across the kerbs, you have to wonder if all these small bits can actually make any difference. But the answer is they do. It’s what happens when the car lands that gives the driver the confidence to attack the corner, and if a car lands and grips then the driver will push harder.
These small details (red arrows) that Mercedes has added to its already incredibly complicated bargeboard area will just improve consistency and reattachment of the airflow in a certain area. This will mean the underfloor will recover faster from a vertical acceleration.
In the longer, more stable corners such as the two Lesmos and the Parabolica, this will improve the overall downforce from the underfloor.
