The 11 Formula 1 teams have brought a combined 30 upgrades in a busier-than-expected Monaco Grand Prix tech update.
The new winglets attached to the rear wings – most aggressively from Mercedes, Red Bull and McLaren – sparked intrigue on Thursday, but there’s much more to the packages brought by the teams, including one other change that’s been adopted almost unanimously across the board.
Here’s a team-by-team breakdown of what’s new:
McLaren: 6 upgrades
McLaren has been by far the most aggressive team ahead of the Monaco GP. As well as its winglet on the rear wing to help with airflow and downforce for exiting corners better, it has other significant tweaks, too.
Like a number of teams, it has tweaked the front suspension fairings, “allowing for increased clearance to the wheel at high steer angles”.
The rear suspension and beam wing have also been tweaked to help aerodynamic efficiency.
Finally, a ‘stay’ has been attached to the diffuser to improve robustness.
Red Bull: 4 upgrades
The headline of Red Bull‘s upgrade is its squirrel-shaped winglet on the rear wing, but it has three other significant upgrades.
New front brake cooling exit ducts and opened-up sidepod exits have been introduced with the cooling demands of Monaco in mind, while a similar-to-McLaren front suspension change should also help here.
Audi: 4 upgrades
Audi has removed the straight-mode actuators – they’re not needed as the wings are fixed and straight mode has been disabled for this weekend – with a small winglet to the rear wing added.
Elsewhere, it has an interesting rear-view mirror design, the only one of its kind brought this weekend, shaping airflow to the sidepod, and a new rollhoop and engine cover to aid cooling.
Its changes make for a good cross-section of upgrades spread from front to rear.
Aston Martin: 3 upgrades
Aston Martin’s proper upgrades won’t come until summer, but there are tweaks here alongside Honda‘s pre-event driveability gains.
A new exhaust wing follows the trend of 2026, while revised front suspension and bodywork cooling louvres are common for this event.
Aston Martin, along with Haas, has not brought a winglet to Monaco.
Haas: 3 upgrades
Haas brought a big package to the last event in Canada – and is optimistic it will give a better account of its upgraded F1 car in Monaco – but hasn’t stopped there.
You’ll have started to see a trend across the teams’ upgrades; a winglet on the rear wing, front suspension changes, and a new exhaust wing like Aston Martin create the package.
Ferrari: 3 upgrades
The favourite – or is it? Anyway, Ferrari has the typical front suspension tweak, but has two slightly more interesting changes onboard too.
It has brought aero-load generating devices for the floor and diffuser.
Racing Bulls: 2 upgrades
The typical front suspension tweak, plus a flap and central winglet on the rear wing complete Racing Bulls’ attempts to head the midfield in Monaco.
Williams: 2 upgrades
Williams has a new exhaust tailpipe, described as a “further step” from the previous two grands prix, and is another team with a front suspension tweak.
Alpine, Cadillac and Mercedes: 1 upgrade
We’ve grouped these three teams together as they’ve all elected to employ the winglet on the rear wing. The gap in complexity between Mercedes and Cadillac perhaps shows the relative difference between the front and the rear of the grid but, nevertheless, every little helps.
