Technical updates: 2026 Belgian Grand Prix

McLaren’s new rear wing is one of multiple upgrades being introduced by teams at the Belgian Grand Prix, with only Ferrari and Aston Martin not bringing new components.

As highlighted ahead of the race weekend, McLaren has a new rear wing assembly that is particular to Spa-Francorchamps and offers an efficient drag reductions, while there is also a “small revision to the rear wing endplate resulting in improved flow conditioning and aerodynamic characteristics across the full operating range,” according to the team.

Mercedes also has a circuit-specific change to its rear wing for lower drag levels, while there is also increased camber on the top edge of the front wing endplate, as well as revised rear drum winglets.

The rear wing is also an area of focus for Red Bull, although it’s a relatively minor change to the pylon profiles to maintain flow stability. That’s a tweak to a previous version of the wing, as Red Bull has dropped its rotating Straight Mode design after two incidents for Max Verstappen in two races.

Williams has a new floor body “to change the distribution of diffuser expansion volume across the car operating envelope,” as well as a local trim added to the floor for adjust the balance and drag levels. There is also a reduction in load from the rear brake duct winglets – a change that is specific to the demands of Spa.

Perhaps the largest update is at Racing Bulls (pictured, top), where there is a new engine cover, roll hoop, front corner and rear wing. The engine cover relates largely to the sidepod to better control airflow, while the roll hoop is narrower to provide better flow quality reaching the updated rear wing. That wing features a number of changes to the mainplane and flap profiles that Racing Bulls says allow the rear wing to generate downforce more efficiently.

Haas has introduced a new front wing – including new endplates – and has made marginal geometry changes to the deflector on the front corner of the car. There’s also a change to the beam wing, with a lower-downforce option for Belgium.

Audi pairs a new aerodynamic configuration for its upper rear wing with a new diffuser – the latter seeing a sidewall winglet updated to enhance the airflow at the rear of the car – while Alpine has a new Halo winglet and Cadillac has revised its front wing endplate.
