McLaren are introducing their most extensive upgrade package for three months as the Formula 1 season resumes after the summer break.
The team is introducing a new rear wing assembly, revised its suspension at the front and rear of the car, modified its front brake air inlets and tweaked its floor.
It is the biggest revision to the MCL38 since the Miami Grand Prix, when the team made a noticeable step forward in performance which helped Lando Norris claim his first victory.
In its submission to the FIA detailing the changes, McLaren described the car’s rear wing as a “completely new” and more efficient design, involving changes to the upper and beam elements. The front brake scoops have been redesigned to improve the airflow further down the car and generate more downforce. The front and rear suspension have been revised to suit these changes. McLaren has also reshaped the edge of its floor, again to generate higher loads.
Red Bull is the only other team among the four front-runners to have confirmed any changes to its car this weekend. However these are not as extensive as McLaren’s package for its car.
As they expect cool conditions at Zandvoort this weekend and subsequent rounds, Red Bull have produced a revised engine cover with a narrower central exit. The team is expected to use the revised bodywork it introduced at the Hungarian Grand Prix at this track, which suits higher downforce circuits.
Red Bull’s other minor revisions to the RB20 include changes to the halo and mirror supports, aimed at improving the air pressure downstream from these parts in the centre of the car.
Neither Ferrari nor Mercedes have brought any upgrades this weekend. However Mercedes intend to reinstate the new floor they ran in practice at the Belgian Grand Prix, but did not use in the race.
Aston Martin and Sauber have also brought no updates for this race. Williams have brought their first significant upgrade of the season which mostly involves changes underneath the car and to its sidepods and engine cover. Alpine, RB and Haas have brought some new parts, the latter introducing a revised front wing and associated updates at the front of its car.
