McLaren bring huge Dutch GP upgrade package in Red Bull pursuit

McLaren and Williams lead the field in upgrades for the Dutch Grand Prix, where four of the 10 teams have submitted no updates at all.

In the battle at the front, the Woking squad have introduced changed front and rear suspensions at Zandvoort.

A new front brake scoop on the front corner has necessitated the revised front suspension, with the emphasis on increasing performance.

There is also a revised floor edge, which will help with local load and improving overall floor performance.

The modified rear corner is joined by a track-specific, high-downforce rear wing and beam wing.

With Ferrari, Mercedes (who will look to reimplement its failed Spa-Francorchamps upgrades) and Aston Martin submitting no changes, it is just Red Bull in the top five teams also introducing updates.

The reigning constructors' champion is, however, only bringing minor changes to Zandvoort.

In addition to a circuit-specific engine cover, which will aid cooling, there is an updated halo and wing mirror stay on the RB20.

Williams

Williams, meanwhile, will have a noticeably different-looking sidepod inlet this weekend.

That change will improve loss management from the front of the car, and should therefore unlock performance gains overall.

It also has an updated diffuser and completely new floor geometry, with both the front and sides being re-profiled. The front of the floor has also been raised.

Like, Red Bull, there is a new engine cover, or coke, but the Grove-based team's aim is to increase performance. It is an alteration that should complement the sidepod changes.

Lastly, there is a new central air intake on the FW46, where the main roll hoop geometry is revised in order to remove mass from the structure. Like the coke, it also works in conjunction with the sidepods to improve aerodynamic efficiency.

The rest of the bottom five

Alpine has updated its front suspension and rear corner, by way of its rear brake duct furniture, to improve performance to improve flow and to better manage the trade-off between downforce and drag, respectively.

RB also has changed rear brake duct geometry - as well as updated winglets - to lower brake cooling requirements in order to reduce the size of the ducts and create space for more downforce-generating devices.

Whilst Stake has not submitted updates, Haas has a revised front to its car. The American team is introducing an upgrades front wing, nose, front suspension and front corner.

All is with the aim of improving flow conditioning and therefore performance, with an emphasis on the central flow of the car.
