Ferrari introduced a new but simplistic solution in Melbourne, as a winglet could be found mounted on either side of the curved exhaust surround and rear wing pillar mounting on the SF-24. It’s interesting that we haven’t seen anyone place winglets here before, given it’s clearly allowable within that box region especially as Formula 1 designers have a penchant for placing aerodynamic surfaces wherever possible, with devices like the T-wing a testament to this.
As we’ve seen from other teams that have opted for this solution, Sauber has also hung two winglets from the endplate above the semi-detached flaps, which will not only introduce vorticity of their own but also work in conjunction with those created by other surfaces in that region. Unfortunately for Zhou Guanyu, damage to his front wing during qualifying meant that he had to start the race from the pitlane, as the team didn’t have any spares of this new configuration at its disposal.
