Ferrari, McLaren and Red Bull have brought major front-to-back upgrade packages for their Formula 1 cars to the Miami Grand Prix as they try to catch early benchmark Mercedes.

The first three rounds of 2026 have been dominated by Mercedes, which has started the new rules era with a clear advantage.

After a month to work on finalising upgrades, though, its would-be rivals for victory have revealed big changes to their designs for a weekend Mercedes only has minor updates itself.

Ferrari

Ferrari - described by some as already having the best chassis in 2026 - is Mercedes' nearest competitor and has finished on the podium in all three races so far. And it has the biggest set of upgrades of all the teams in Miami.

The front wing endplate has a revised footplate outboard channel and the addition of a top forward vane to work hand-in-hand with front-corner changes, where the front deflector upper and lower edges have been developed, along with a rear deflector lip, targeting flow feature stability and front wheel wake management.

Front suspension leg fairings have been reprofiled to optimise load distribution across the legs, delivering load gains while managing downstream impacts.

There are multiple floor changes. For the body of the floor itself, Ferrari has targeted keel volume optimisation, additional front floorboard (previously bargeboard) vertical elements, revised board stays and a reprofiled leading edge, all returning a net load advantage.

In combination with this front floor update are multiple other changes comprising the floor edge, diffuser, rear suspension, beam wing and rear tail.

Ferrari says this focuses on a "load increase across the full operating window" while the rear trackrod fairing update in the rear suspension, together with revisions to its innovative exhaust wing, "provides a favourable pressure gradient for the diffuser, in an efficient manner".

The rear wing has also been updated with reprofiling of the mainplane and flap, addition of a central bracket flap and reworked pylon junction, focused on maximising drag shedding in straight mode while keeping cornering load.

Upwashing volumes and upper endplate detailing have also been added to the rear wing endplates to improve flow conditioning around the rear wing.

McLaren

Though Mercedes' engine edge is well-established, its customer McLaren has admitted that it was also carrying an aerodynamic deficit.

Its upgrades will be introduced across two phases, here and at the next race in Canada, but the Miami package itself is significant enough.

Revised front corner furniture improves interaction with the front wing for better overall flow conditioning, while the engine cover has been modified to improve flow conditioning and offer an aerodynamic load gain in that area, increasing aerodynamic efficiency.

The sidepod inlet has been revised to work with "completely new" floor geometry, which is designed to increase load and efficiency. Similarly, rear corner "furniture" has been revised to interact with the new floor better.

McLaren has also brought a new rear wing with new elements and revised endplates.

Red Bull

Red Bull has had a poor start to 2026 with both Max Verstappen and Isack Hadjar critical of its car, and it has responded with a big set of changes too.

All three front wing elements and the endplate, including the diveplane, have been optimised for more load with the same or improved flow stability.

Revised front wheel ducts aim to improve efficiency by drawing air from the highest pressure source and allowing it to exit with minimal blockage.

The sidepod inlet and mirror supports are revised to accommodate a new floor, which has revised bib geometry, and forward floor structure changes. This blends with sidepod and engine cover updates to produce more aerodynamic load, and a more stable downstream flow.

The latter could be Red Bull's way of trying to address a shifting balance that both drivers have said makes the car very unpredictable to drive.

At the rear, inboard rear suspension shrouds are blended to match the new engine cover while the rear wheel bodywork is subtly revised for brake cooling and local flow improvements.

Interestingly, Red Bull describe its rear wing as having the mechanism and attachments "revised to allow more travel in straight mode" - which is expected to mean it opens the way Ferrari's unusual 'upside-down' wing does.
