Following the nose designs controversy in 2014 due to the FIA regulations, 2015 brings significant visual changes in the cars. The rules now require that all teams comply with a 9000mm² cross section 5cm behind the very tip of the nose 20000mm² cross section forming where the nose touches the chassis.
The effect? A challenge from a technical view to compensate for the big aero impact of the changes, as the newly nose section creates a blockage, reducing downforce.
This results in four design layouts between the teams. Williams, Red Bull, and Toro Rosso have opted to keep a small piece at the front of their nose. Others like Mercedes and Lotus keep a shorter nose with a slight point. Ferrari, McLaren, and Force India have a longer and wider nose. And finally Sauber has the most different nose of all, choosing a wide design a thick thumb section to the front of the nose.
