Overview

• Eight of the ten teams have introduced new aerodynamic and cooling packages at Spa-Francorchamps as they exhaust in-season development under current regulations.
• Red Bull’s RB21 features a five-pronged upgrade that includes revised front wing elements, merged sidepod inlets, an updated engine cover, cambered suspension fairings and tweaked brake duct bodywork.
• Ferrari has deployed its re-optimised rear suspension geometry, tested at Mugello, to reduce sensitivity to ride-height changes and widen the car’s optimal operating window.
• Williams has rolled out a comprehensive floor redesign with reprofiled fence geometries, an advanced floor edge wing and a deeper sidepod inlet to boost downforce without sacrificing cooling.
• Mercedes, McLaren, Aston Martin, Alpine and Racing Bulls have added focused tweaks—from front wing endplate and low-drag rear wing updates to shorter-nose tests—while Haas and Sauber opted out of upgrades for the sprint format.
