The group’s mirror test that proposes changes in F1 regulations in 2023.


Windshields have long been a problem in F1, and aerodynamicists like to minimize their damaging effects, even at the expense of drivers’ ability to see what’s going on around them.

In their efforts to eliminate the aerodynamic efficiency of mirrors, the designers not only chose to have as small a body as possible around the mirror, but also turned to a trend that uses flow-mode attachments to change the air flow.

As you would expect from a full grid test, there was a range of different solutions between teams hoping to gather information for themselves and the FIA.

Current updates

Alpine has been one of the most active teams on the grid this season when it comes to releasing new parts, with the Enstone team having something new available at every race of the season so far.

Sure, some of the packages that have arrived have been more important than others, but it’s nice to see that the team has been able to maintain a steady stream of development that doesn’t just take influence from those who make it. ;environment, but it also has its design features.

For the Dutch Grand Prix, the team made some improvements to improve the pre-existing power set that they planned to use on this site.

At the front of the car, this means minor changes to the design of the front wing, with a new curve introduced to reduce downforce and help balance the car with changes placed at the rear.

A beam wing has been modified by Alpine at the rear of the car, with a short chord upper used in its stacked, biplane-like arrangement.

Interestingly, there were two configurations available so far, which are medium low power and low power. This new configuration will sit somewhere in between, if not directly in place of the mid to high end option.

Alpha Tauri took advantage of the Dutch GP to make improvements to its rear wing. The Faenza team has fixed the transition between the wing elements and the end panel.

The bow is now tighter, resulting in increased main wing span and higher camber, and greater wingtip shear to compensate for any additional wind that may occur.

Williams had a new front wing for the Dutch Grand Prix, with the team making changes in this area for the first time since its update at Silverstone.

The change also did not require the manufacture of a completely new wing, which is obviously a good thing when considering the cost limit. The outer part of the upper flaps and the transition with the end plate has been identified as a step that can lead to an increase in performance.

This part of the wing is relatively sensitive due to the performance balance that must be made between creating downforce and curves and using the intersection to affect the outward flow generated by the wing.

Alfa Romeo made changes to its rear brake housing during the Dutch Grand Prix, the team aiming to increase performance that will not only remain in the Zandvoort track.

In this event, the shape of the deflector was modified, the team expects to increase the performance of the internal flow while having the secondary benefit of improving the flow in the diffuser.

The team placed a large Kiel probe behind the C42 during free practice to ensure the parts performed as their simulations predicted (below).
