Audi Leads Baku GP Upgrade Push as Five Teams Opt Out of Aero Changes

Audi brought the largest upgrade package to the Formula 1 Azerbaijan Grand Prix in Baku, submitting 14 revised components to the FIA as six of the 11 teams declared updates for the weekend. Conversely, five teams—Mercedes, Ferrari, Aston Martin, Alpine, and Haas—submitted no aerodynamic changes. Aside from Audi, teams including McLaren, Red Bull, Williams, Racing Bulls, and Cadillac introduced technical modifications primarily focused on the floor, wings, and cooling assemblies.

Audi's extensive package touches nearly every aerodynamic surface on the car, featuring a new front wing, nose fairing, floor, bodywork, and rear wing assembly designed to boost performance and evaluate factory development tools. McLaren declared eight updates centered on revised sidepod inlets and a modified rotating rear wing flap to reduce drag on Baku's long straight. Red Bull and Williams also introduced floor-led developments aimed at increasing local load and improving airflow downstream.

Despite introducing no aerodynamic updates, Aston Martin faces heavy grid penalties for both Fernando Alonso (a 25-place drop) and Lance Stroll (a 20-place drop) after taking additional power unit components beyond their seasonal allocations. The team plans to use practice sessions for extensive testing while addressing engine braking drivability issues noted by Honda. Haas and Ferrari likewise opted against new aerodynamic parts, focusing instead on component rotation and tyre optimization.

The Baku circuit presents severe operational challenges regarding energy management and closing speeds along its main straight. Honda and Aston Martin noted that battery deployment could run out before the end of the straight, while Fernando Alonso raised concerns over dangerous speed differentials between cars on preparation laps and those on flying push laps. Additionally, tyre warm-up across Pirelli's nominated C3, C4, and C5 compounds and limited overtaking opportunities were highlighted by drivers like Max Verstappen and Lando Norris as key factors for the weekend.
