Technical updates: 2026 Hungarian Grand Prix

Aston Martin’s B-spec car headlines a large number of upgrades at the Hungarian Grand Prix.

Aston Martin has not updated its car since the start of the 2026 season, having opted to commit to a complete redesign that would be introduced at once. This weekend’s race at the Hungaroring is when the new chassis has been delivered, and amounts to 16 different areas of development on the FIA’s car submissions.

A new front wing and nose highlight how the airflow will change across the entire car, along with new front brake duct external elements. Then there is a new floor – with Aston Martin saying there are changes to all of the permitted surfaces – and diffuser, as well as a revised inlet shape on the sidepod and subtle bodywork tweaks.

The cooling louvers have been updated, as has the rear suspension and brake ducts to improve rear performance, with a new rear wing, beam wing and rear wing endplate seeing all surfaces revised too.

The next most significant update appears to be at McLaren, where there is a new floor and floor board that the team says results “in an improvement in flow conditioning and local load generated across all conditions.” The front corner and front brake ducts have been amended, as has the rear corner and rear wing endplate.

Mercedes has a new rear winglet and tail winglet that merges into the rear wing brace, as well as a wider bodywork rear exit for cooling purposes. At Red Bull, the rear wing has also been updated with revised pylon profiles and flap geometry, while there is a new diffuser that the team says has been inspired by competitor designs.

Ferrari has a new rear wing and rear wing endplate to increase local load, while Williams follows suit with a circuit specific rear wing and floor design that both increase downforce for the Hungaroring.

There’s a further tweak at Racing Bulls – where Liam Lawson gets the upgraded chassis first introduced on Arvid Lindblad’s car last week – as a new rear wing and additional cooling louvers are added to by roll hoop winglets to improve airflow to the rear of the car.

Haas and Audi have both introduced new rear wings, with Haas focused on the Straight Mode fairing and Audi the endplates. Cadillac brings an updated inlet scoop on its front brake ducts to aid with cooling, after issues with the previous design in Austria.
