Max Verstappen’s late 2025 Formula 1 title push has received another shot in the arm as Red Bull unveiled a raft of upgrades at this weekend’s Mexico Grand Prix.
Third-placed Verstappen has closed to within 40 points of McLaren’s championship leader Oscar Piastri after taking three wins out of four. Heading to this weekend’s Mexico GP as the pre-event favourite, the Dutchman will now receive another batch of upgrades to his RB21 to improve aerodynamic performance.
Red Bull has brought the latest iteration of its floor design first introduced in Monza, with a reprofiled upper surface rearwards of the outer floor, which should yield extra aerodynamic load. It also reworked its edge wing to interact with the reworked floor.
The floor has also received a revision to its interaction with the sidepod, as the latter has been changed to provide more cooling.

At an altitude of 2200 metres above sea level, Mexico City’s Autodromo Hermanos Rodriguez comes with additional cooling demands due to the lower air density, prompting Red Bull to revise the exit area of its engine cover, as an additional option that can be used if needed.
The squad also brought larger front brake ducts due to the high demands on the brakes. At the time of writing, it is not yet clear if Verstappen’s team-mate Yuki Tsunoda will also receive the full upgrade package, with the Japanese driver usually a step behind whenever new upgrades are introduced.
Elsewhere, Ferrari has deployed larger rear brake ducts and bodywork cooling slots for the same reasons.
The likes of Alpine, Racing Bulls, Williams and Sauber have also all brought bigger cooling slots to cope with Mexico’s demands.
