Max VerstappenMGU-KNEW2nd of 3PU AncillaryNEW2nd of 6
Rear CornerCircuit specificCooling Rangelow coolingRevisedConfirmed

Revised inlet and exit geometries Given the braking energy demands of Suzuka, minor changes have been made to the rear wheel bodywork to suit the brake material requirements.

FloorPerformanceFlow ConditioningRevisedConfirmed

Upper surface revised to meet new sidepod Consequential changes to meet new sidepod geometry and extending forward to the chassis, benefitting from the efficiency to offer more load.

Sidepod InletPerformanceFlow ConditioningRevisedConfirmed

Revised inlet and therefore surrounding to meet chassis and floor.

To ingest higher pressure air to the sidepod inlet from upstream, the profile has been revised based upon simulation and initial running results yielding improved efficiency

Coke/Engine CoverPerformanceFlow ConditioningRevisedConfirmed

Surfaces adapted to meet the new sidepod inlet geometry As a consequence of the inlet changes, the sidepods have been revised to suit and offer an efficiency improvement for cooling and downstream surfaces.

Front CornerPerformanceFlow ConditioningConfirmed

Front deflector redesigned The front deflector has been redesigned to improve the management of the local flowfield, ensuring a consistent delivery of performance throughout the entire operating range.

Rear Wing EndplatePerformanceLocal LoadConfirmed

Re-designed of the lower part of the Rear Wing Endplate The end plate has been redesigned to improve the flow conditioning at the rear of the car while also generating local load.

Rear WingPerformanceLocal LoadConfirmed

SM pod fairing and reprofiled elements Local adjustments have been made to the rear wing to extract more performance out of it, both in Cornering and in Straight mode.

So yes, it might seem like only one upgrade package, but there really is a lot more at stake for Alpine at Zandvoort.

But even though Greenwood insisted Alpine has stayed "in the race" while it's held back on new parts, it will head into the second half of the season with much riding on an upgrade package being brought to the Dutch GP.

Front Wing EndplatePerformanceLocal LoadConfirmed

The edge of the outboard footplate is raised.

In conjunction with the front wing change the modifications improve the load distribution at the outboard end of the wing.

Reduced front brake duct inboard exit area

The Suzuka Circuit braking duty allows us to introduce a smaller front brake duct geometry, trading off brake cooling for external aerodynamic performance benefits

Front WingPerformanceFlow ConditioningConfirmed

The FW SM actuation system was simplified allowing smaller exposed geometries The FW SM linkage was simplified, enabling a reduced external envelope.

The smaller linkages decrease blockage and consequently improve the airflow directed towards the rear of the car.

Front SuspensionPerformanceStructural ImprovementRevisedConfirmed

Compared to the launch car, a revised set of suspension claddings are available to package efficiently around the updated suspension structures.

The incidence and profiles of the external claddings have been optimised to work effectively with the new internal suspension structures to ensure that the impact on the downstream flow field is mitigated. Atlassian Williams F1 Team 3
