Red Bull is the only one of the leading four F1 teams to submit an
upgrade to the FIA for the Dutch Grand Prix. The Milton
Keynes-based squad has introduced an updated front wing for the
RB21 at Max Verstappen's home race, whilst McLaren, Ferrari and
Mercedes have detailed no visible changes to the MCL39, SF-25 and
W16, respectively. As confirmed by the motorsport governing body's
disclosure document, due to the demands of Circuit Zandvoort, Red
Bull has increased the chord length of its front wing flaps to
increase the load available via angle. The six-time constructors'
champion is one of just three teams to bring a development to its
car for the first weekend back after the F1-mandated summer
shutdown. Alpine and Stake have both made changes to the rear
corners of their cars. The former has altered the rear brake duct
furniture, which includes a set of reprofiled winglets. These are
designed to improve the wake management of the rear wheels. The
latter, meanwhile, has updated the rear brake duct vane design to
improve flow around the diffuser and rear wheels. With F1 set to
overhaul its regulations over the winter, relatively few upgrades
are expected over the final part of the season as teams turn more
and more of their attention to 2026.
