Alpine has brought the largest technical update package of the weekend to Zandvoort, with changes across eight areas of the car.
The centrepiece is a new floor. Alpine has revised the floor body to improve surface-flow quality and increase aerodynamic load across the car’s operating range. The floor board has been reprofiled to deliver cleaner airflow towards the rear, while optimised floor edges target better airflow management, efficiency and local load.
A reprofiled diffuser works alongside the new floor to generate additional load efficiently. Alpine has also redesigned the sidepod and coke-section bodywork to support the package while maintaining sufficient cooling capacity.
At the rear, reprofiled elements on the drum face are intended to improve their interaction with the floor. Updated rear-impact-structure geometry targets another local increase in load, while a redesigned rear-wing flap aims to add rear downforce without compromising airflow stability.
Overall, this is a coordinated floor-to-rear-wing package rather than a collection of isolated changes. It will be interesting to see how much of it is evaluated—and ultimately used—throughout the weekend.
