Technical upgrades: 2025 Saudi Arabian Grand Prix

Multiple teams have brought developments to the Saudi Arabian Grand Prix as McLaren looks to hold onto its advantage at the head of the field.

McLaren has an updated diffuser that has been reshaped to improve overall flow conditions, that the team says aims to deliver a gain in aerodynamic performance. Added to that, there’s a new rear brake duct winglet arrangement that should improve aerodynamic efficiency.

After introducing a new floor in Bahrain, Ferrari continues its development program with changes to the rear wing and beam wing of the car, particularly surrounding drag reduction at such a high-speed venue. There’s a less cambered top rear wing flap on offer, while Ferrari has also brought a rear wing and beam wing from last year that are a larger step in delivering a lower-downforce setup.

Red Bull has brought a cooling upgrade with an enlarged central exit to its engine cover to help reject the heat ahead of high temperatures in Jeddah, but there’s a similar beam wing option to the one at Ferrari, with less camber providing lower downforce and drag settings if required.

Aston Martin, Haas and Racing Bulls all follow the same trend with less-aggressive rear wing options that allow a reduction in downforce and drag, but Haas and Racing Bulls also have a front wing that features a relaxed flap profile that would help balance the car if either team uses the less-loaded rear wing.

There’s a more substantial set of new parts at Stake, although the majority also are targeted at the demands of the Jeddah Corniche Circuit. Aside from lower-downforce front and rear wing options like many teams, there’s a rear wing endplate that combines with the rear changes to provide an increase in overall efficiency.

Stake’s most notable upgrade relates to its floor, however, where it has made changes to its central floor geometry. The team says the development aims to improve flow characteristics around the rear of the floor, that should produce an efficient downforce gain.

Mercedes, Alpine and Williams are the only three teams not to submit any updated parts to the FIA for this weekend’s event in Saudi Arabia.
