All 10 Formula 1 teams have outlined significant evolutions of their cars that will kick-off the 2025 season at the Australian Grand Prix.
As it is the first round of the year, teams have been referencing some of the changes they have made to the cars that ended last season, when they last submitted developments to the FIA at a race weekend in Abu Dhabi. Defending constructors’ champion McLaren has a relatively modest set of updates, with the front brake duct revised for better aerodynamic performance.
There’s also a low cooling option of the new duct in case of low temperatures on Sunday, while two beam wing designs have been prepared for Melbourne, one with a single element and one with a double element, with both delivering increased aerodynamic load compared to the launch version.
Ferrari explains how its new front suspension layout has “unlocked several development paths”, particularly in terms of interactions with the front wing and improvements to the airflow downstream. There are also more compact sidepods, and a redesigned rear wing that improves aerodynamic efficiency.
Red Bull outlines a huge range of changes to its car for 2025, with the front wing, nose, front suspension, floor, sidepods, cooling louvres, rear suspension, beam wing, rear wing and rear wing endplate all updated. It is the floor that remains a big performance differentiator, and in this area Red Bull says a “revised shape improves pressure distribution given other changes to the floor to extract more load and maintain flow stability”.
At Mercedes, a change to the low rear track rod delivers improved airflow to the floor, where updated floor tunnel profiles increase load and flow quality to the diffuser. There’s also changes to the sidepod – including an increased undercut – and new beam wing and rear wings that Mercedes says is more efficient.

Last year’s fifth-placed team, Aston Martin, has a new nose and front wing solution, as well as more efficient front brake ducts and a revised sidepod inlet. The undercut of the sidepod has also been increased, alongside what the team describes as subtle changes to the floor and reposition of the four floor fences.
Further changes to the Aston include new rear suspension fairings, updated rear brake ducts, and new beam and rear wings.
Alpine was one of the teams that enjoyed an encouraging start to the year in pre-season testing and it attributes that to the main changes to its floor, describing it as a “complete floor optimization” across fences, floor edges and the diffuser. There is also a new sidepod inlet and engine cover bodywork in 2025, alongside tweaks to the rear corner, rear wing endplates and rear suspension fairings.
The battle for sixth place in the constructors’ championship last year was between Alpine and Haas, and the latter has listed a number of redesigned items to try and improve this season. The front wing has been revised alongside new front wing endplates, and the sidepod inlet moved further forward and made more compact.
Like many teams, an entire new floor has been developed, alongside an increased undercut to the sidepod and narrower engine cover, and changes to the beam wing, rear wing and rear corner cooling.
While Haas has stuck with the 2024 Ferrari front suspension – only updating the fairings – it has taken this year’s rear suspension from Ferrari.
Racing Bulls has been particularly secretive with its updates, only listing three items it has changed as it outlines a new sidepod inlet, front wing and front suspension, that will have an impact on the rest of the car downstream.
A new front wing and endplates at Williams work in conjunction with a wider sidepod and reprofiled undercut, although the team suggests there have been “geometric changes to the main bodywork components”. It has brought specific cooling options for its engine cover based on the mixed weather forecast at Albert Park, too, with high temperatures predicted for qualifying but potential rain on a far cooler race day.
And finally at Stake, a new front suspension is intended to deliver improved handling and mechanical grip, but it is bodywork that the team highlights as the main updates. The team says all areas have been developed, predominantly upper bodywork designs, and a significant redesign of the floor.
There are also new front and rear wings, and a revised cooling system layout that has been reworked in conjunction with a new gearbox casing and rear suspension components.
