Mercedes-style F1 adjustments help McLaren move forward

The first of these changes was on the front of the MCL35M, and McLaren finally found it suitable for adopting the chassis “horn” that had been used by other teams for quite some time.

The one introduced by McLaren is similar to the one used by Mercedes, rather than the variation of multiple elements found elsewhere such as Ferrari and Alfa Romeo.

These winglets help divert the airflow through the area to improve the performance of the flow down the vehicle.

McLaren MCL35M Rear Cooling Outlet

At this point in the season, McLaren chose to better handle the cooling requirements of the Mercedes power unit and slim the rear cooling outlet of the car to increase aerodynamic gain.

To offset this, the team has the option of opening the cooling panel next to the cockpit. This was done by McLaren in France and was easy to find as it was raw carbon rather than a painted item.

The panel can only be seen on the left side of the car, suggesting that the components inside the side pods need a little more cooling assistance than on the right side.

At the rear of the car, the team made significant changes to the design of the rear wing end plates and chose a set of horizontal louvers, usually with slots for creating strakes.

The panel incorporating these louvers looks almost like a mirror image of the panel at the top of the end plate. The louvers are curled up instead of down, and the airflow is moving outwards rather than inward.

Ferrari arrived at the French Grand Prix with a revised front wing assembly featuring many subtle changes.

The new spec wings are at the top two of the figure, showing how the flat part of the footplate was removed. This widens the arc and changes the shape, velocity, and direction of the generated vortex.

On the other hand, the ratio of adjustable flaps has also changed, and the adjusters have moved further outwards, so adjusting the flaps will have a greater effect on the top two flaps.

This allows the team to trim the car a little more to improve the balance of the car, but it also allows airflow to be directed to and around the entire front tire in the outermost section.

Ferrari also made changes to the rear wing at the French Grand Prix, significantly cutting the lower tail section of the end plate (blue arrow).

Mercedes has chosen to make minor changes to the French steering wheel to prevent the recurrence of problems that Lewis Hamilton struck during the reopening of the Azerbaijan Grand Prix.

Mercedes has deployed a button guard to prevent the button from being inadvertently pressed (See the inset above), you’ll need to press a more careful button to deploy Brake Magic.

AlphaTauri continued to look for AT02 performance as it introduced a new floor at the French Grand Prix.

The update has processed the area in front of the rear tires. Previously, one flap was installed above the scrolled-up floor section, so the flap was added.

However, this is shorter than in previous versions. This is because an extra strake has been added to the edge of the floor (red arrow), which also shortens the scrolled section.

AlphaTauri introduced a new front wing at the Spanish Grand Prix, changing some aspects of the overall design, including the shape of the flap tip, the strake underneath the wing, and a revised footplate shape.

The foot plate is square. This means that the shape of the surface leading to the cavity in the foot plate has also changed.

After the accident at the French Grand Prix, Yuki Tsunoda’s car was lifted and this part of the wing can also be seen from below.

There is a strake in the center of the foot plate (red arrow), and the airflow through the cavity appears to be pumped into a channel carved into the lower side of the end plate.
