Huge Red Bull and Ferrari upgrades revealed ahead of tricky Belgian GP

The fresh upgrades Red Bull and Ferrari both hope will revitalise their F1 seasons have been revealed ahead of the Belgian Grand Prix at Spa. 

For Red Bull, it is in the last chance saloon to help Max Verstappen defend his drivers' title, as the Dutchman finds himself 69 points behind leader Oscar Piastri. 

Like the other nine teams, Red Bull will soon need to switch full focus onto the 2026 machine, given the scale of the change in the technical regulations, meaning upgrades are likely to cease the longer the season goes on.

The package Red Bull hopes will turn its fortunes around and allow Verstappen to challenge the McLarens includes a brand-new front wing design where elements have been modified to increase downforce. 

More performance-related parts have been brought to the rear corners of the RB21, as well as a front suspension tweak to aid airflow over the car.

The sidepod inlets and engine cover have also been tweaked slightly to aid power unit cooling for this event.

As for Ferrari, the details around its much-vaunted rear suspension have been made public, following a private test at Mugello last week using the system.

In the submission to the FIA, Ferrari has described its new parts as an 'updated rear suspension geometry' - achieved through a "re-optimisation of the wishbone fairings." A circuit-specific low downforce rear-wing has also been brought. 

Of the other leading teams, Mercedes' W16 has a fresh front-wing and rear corner to aid performance for George Russell and Kimi Antonelli, whilst McLaren has an updated version of its low downforce rear-wing to help reduce drag.

Upgrades for the 2025 F1 Belgian Grand Prix

Aston Martin and Williams have also unveiled considerable upgrade packages.

Aston, currently languishing in a disappointing eighth in the constructors' championship, now has a new front wing, nose, rear wing and beam wing on its AMR25s as it seeks a performance boost over the second half of the season.

Williams, which started the season strongly but has scored just eight points in the last five races due to a lack of updates on the car, has reprofiled the floor fences and floor edge, whilst the sidepod inlet has been modified. 

In addition, the coke/engine cover has also been tweaked.

On the Alpine, there is a new rear wing and beam wing; Racing Bulls has reprofiled and updated the rear wing and rear corner, which is more circuit specific, whilst the diffuser geometry has been updated.

Only the cars of Haas and Sauber are unchanged for this weekend.
