Technical updates: 2025 Emilia Romagna Grand Prix

All but two teams have brought upgrades to the first European round of the season as a tripleheader of consecutive weekends kicks off at the Emilia Romagna Grand Prix.

Three races on consecutive race weekends offers the ability to get significant value out of new parts, with Monaco next weekend rarely deemed a good venue to bring developments due to difficulties understanding them on the street circuit. As a result, every team except Williams and Sauber has brought some form of upgrade to Imola, with a number of significant packages.

McLaren has focused on the car of its car, with an update to its rear corner and suspension, while there are also high downforce rear wing and beam wing options brought to the Autodromo Enzo e Dino Ferrari. A front suspension change is described as a reliability update that is deemed a small modification.

There’s a similar update at Ferrari – where there are only small changes despite it being a home race – as a revised scoop geometry and winglet arrangement on the rear corner targets an increase in local load. Ferrari also has higher downforce rear wing and beam wing options available that it says are carried over from 2024.

At Red Bull, a floor change in Miami is followed by a new sidepod shape and radiator duct inlet this weekend, as well as a revised rear suspension fairing and modified wheel bodywork inlet and exit ducts.

Mercedes is the only team of the top four not to focus on the rear corner, with its developments targeting the front suspension. All leg fairings have been updated, as well as front wing elements, combining to improve airflow to the rear of the car. The Mercedes engine cover has also been subtly tweaked, improving load and cooling capabilities.

The largest number of new parts is found at Aston Martin (pictured above), where all aspects of the floor have been addressed. Tweaks to the floor body, edges and fences, as well as the diffuser, are designed to “improve the flow field under the floor, increasing the local load generated on the lower surface and hence performance.”

Further changes have been made to the engine cover shape to complement the floor upgrade, while there are also minor adaptations to the Halo and the beam wing.

There are just two developments at Alpine, where the front wing has been redesigned at the same time as reprofiling the rearmost bodywork panel on the engine cover. The wing offers local load gains, while the latter change improves the airflow delivery to the rear of the car.

Haas is another team to focus on its floor, with a new floor body and associated changes to the floor edges delivering cleaner flow to the rear of the car and necessitating an upgrade to the diffuser as well. The team says the updated floor package delivers higher performance across a wide range of ride heights.

Alongside that development, Haas has worked on its rear corner with new winglets and a revised brake drum face, as well as changing the shape of the lower rear suspension fairing.

The final team with new parts is Racing Bulls, based in Faenza, just a few miles from the Imola circuit. The floor has been addressed with changes to the underfloor channels – also adjusting the floor fences and edge in parallel – while the team has also modified the undercut on its sidepod. The sidepod change promotes high energy flow towards the back of the car and the floor edge wing, with a chassis winglet also added.
