McLaren focus on circuit specific updates

McLaren have brought the most comprehensive package of updates of any team to Monaco, with four of the five stated as being specific to this circuit. This includes a new medium-high downforce rear wing that sits between their existing medium and high downforce assemblies to bring an efficient reduction in drag compared to their high downforce package, yet an increase in downforce versus the medium.

To complement this, new medium-high and medium downforce beam wings have been registered with the FIA, presumably to allow the team to experiment with which offers the best performance for them this weekend.

Given that Monaco is a circuit that places a heavy demand on braking, especially over the grand prix, McLaren have also brought an increased front brake cooling option to deploy if required. Their only update listed for performance reasons is to the front suspension geometry, “to deal with the unique cornering challenges that this circuit brings”, according to the team.

Ferrari opt for old rear wing

Ferrari have brought their 2024-specification rear and beam wings to Monaco to avoid the cost of creating a new high downforce package that is typically only used here and perhaps in Singapore later in the year. This features more loaded top and lower main and flap profiles to cover the low aerodynamic efficiency requirements of Monaco.

In addition, circuit specific modifications to the trackrod, suspension fairings and front brake duct scoop clearance has been made to allow for “greater single wheel angle” which is necessary for Monaco’s layout.

Red Bull look for performance and reliability

Red Bull have a new rear wing and beam wing that is enlarged to help bring additional rearwards aerodynamic load to their RB21 for the Monaco circuit’s demands.

They have also revised their front suspension wishbone fairing to clear the wheel, helping them attain greater steering lock. To achieve the necessary cooling for the front brakes, Red Bull have made a larger front exit duct available with “a consequential trim to the gaitor sealing the upper wishbone” also, in the team’s words.

Aston Martin continue to update the AMR25

After a comprehensive upgrade package last time out in Imola, Aston Martin also have updates here in Monaco but this time it’s all about the circuit’s specific demands.

New front and rear wings have been introduced – the rear wing will generate more load than previous versions so far this year, and the front wing is higher loaded to help balance this out.

Similarly to other teams, a cooling focused, circuit specific update to the rear corner has been made on the AMR25. The inlet has been increased with revisions also to the exit duct and vanes surrounding it to increase the flow through the duct, and therefore the cooling. Alterations to the geometry in this area will also increase local load generated there.

Alpine add new rear wing to their range

Like most teams, Alpine also have a circuit specific rear wing update with a more loaded top main plane to offer more downforce and subsequent lap time gains around Monaco. This comes with a beam wing to complement it, again with more load.

A new trackrod fairing and supports has also been introduced to increase the road wheel angle, meeting the circuit’s characteristics.

Rear wing, beam wing & suspension updates for Haas

Haas have a new circuit specific rear wing which they say “uses the full regulation box to maximise downforce” and comes with them accepting the associated drag increase this brings, as it carries less penalty at Monaco versus other tracks.

To operate with this more aggressive rear wing, a new beam wing is introduced to add further downforce increases. The front trackrod position of the front suspension is also adjusted to meet the steering angle requirements of Monaco, similarly to updates by other teams.

Racing Bulls add new wings to suite

With this being the first real high downforce demanding circuit of the season, Racing Bulls have followed most of the other teams in adding a new rear wing and beam wing to their suite of wings.

The rear wing has increased camber of its upper profiles to maximise load generation, with an altered tip shape helping to improve overall efficiency. The beam wing has double elements to increase the downforce it produces, whilst also supporting the flow attachment of the upper wing.

Further to this, an update to the shape of the cooling exit duct and trackrod ends at the front of the car has been made to address possible clearance issues between suspension and brake duct components at the Monaco track.

Williams bring back 2024 wings

Williams, like Ferrari, are using their 2024 rear and beam wings this weekend to add more downforce and drag in a way that is efficient for use at street tracks like Monaco.

Modifications have also been made to the front steering geometry, similarly to many teams, to meet Monaco’s demands. While these are physically new parts for 2025, the team say they “mimic the changes” routinely made for this circuit to permit additional steering angle, particularly for the hairpin.

A cooling upgrade has also been made available for the front brake duct to increase the brake disc/calliper cooling in a way that they say “is appropriate for Monaco”.

Kick Sauber add track specific rear wing

Kick Sauber have a new high downforce rear wing for this weekend to efficiently increase load, plus a new front brake duct design to increase the brake system cooling flow and accommodate the low average airspeed of this track.

Power Unit Components

Max Verstappen has a new turbo charger and MGU-H on his RB21 for this weekend – both of which are within his allowance for the year so incur no penalties.

Franco Colapinto has also taken a new MGU-K, his car’s third of the four allowed for the season.

Finally, both Ferraris, Red Bulls, the Alpine of Colapinto and Racing Bull of Hadjar have new exhaust systems.
