In the run-up to the Australian Grand Prix, three top-tier teams, McLaren, Red Bull, and Mercedes, have unveiled fresh, medium-low downforce rear wing configurations. These developments are not only designed for Albert Park’s unique track conditions but also reflect a broader shift towards lower downforce wing setups in this generation of racing cars.
This strategy is particularly intriguing because last season, none of these teams had a dedicated wing in this category. Instead, they either used their low downforce options in combination with a different beam wing arrangement or modified their medium downforce variants to match the prevailing requirements.
McLaren’s latest wing design is a direct descendant of the V-shaped mainplane design, first introduced at the Brazilian Grand Prix last season. This new version can be identified by its less invasive elements within the allowable box region, and a more gradual taper from the centreline to the tip section of the mainplane. This design retains the semi-detached tip section of its predecessor, a feature that competitors are keenly observing.
Despite this development, it isn’t clear yet whether McLaren will deploy this configuration during the Australian Grand Prix qualifying and race. The team is weighing this against their higher downforce offering, a decision process evident during Friday’s Free Practice sessions.
Meanwhile, Red Bull seems to have shifted its strategy concerning rear wing solutions. This season, they’ve added a low-medium downforce option for the first race. While there’s no dramatic change in design language, the mainplane and upper flap’s relative distribution have been downsized compared to their medium downforce solution. This adjustment could result in the removal of the Gurney and/or trimming the trailing edge of the flap to rebalance the wing and reduce downforce.
Mercedes, like Red Bull, had previously been reluctant to diversify their rear wing options. However, they’ve begun the season with a new low-medium downforce option. This latest design incorporates a gentler spoon-shaped transition, a deviation from the flattened middle portion that characterised their regular designs.
Conversely, Ferrari hasn’t introduced a new rear wing for the Australian Grand Prix. They have, however, debuted a new solution for the 2025 racing season, inspired by McLaren’s V-shaped mainplane profile. This modification has also prompted a reorganisation of the attachment for the tip section, resulting in a larger endplate cutout.
In conclusion, the Australian Grand Prix will be a testing ground for these new rear wing configurations. These designs are set to influence the dynamics of the race and potentially set new benchmarks for the current generation of racing cars.
