The front wing is closer to the final spec expected to be seen in testing than what we’ve already seen from other teams in their presentations.
Alfa Romeo has opted for a very relaxed exterior section once again, as has become customary after they were the most aggressive when the regulations were changed in 2019.

In the external area, all the elements have been flattened to the maximum, as we can see in the area marked by the red arrow, which is made more evident by the raised section just inside, indicated by the blue arrow.
Like the McLaren design, the central part of the wing is also angled to feed the wedge-shaped lower nose region, which in turn will feed the flat bottom and side struts.
The C42 has a push-rod front suspension, but the design is interesting in that the front upper wishbone is situated high up in the chassis. Attention should also be paid to how all of the suspension and steering arms are angled downwards in an effort to guide the airflow to the desired location.
The front duct fence and wheel wake deflector (green arrow) have also been moved away from the tire assembly to aid cooling and better position the flow created for the aerodynamic surfaces.
Sidpod and floor of the Alfa Romeo C42
The midsection of the car is something of an amalgamation of what we’ve already seen from Aston Martin and McLaren, in that it features a waist-high sidepod with upper cooling gills and huge trim, like the one on the AMR22 , but shares a distinctive layout. of the soil more similar to that of the MCL36 .
The tunnel has its own inner wall (blue arrow) and allows airflow from the center line of the car, under the chassis, to be directed to the upper surface of the floor, which should better feed the flow around the car cutout. pontoon.
That causes not having the maximum possible height or width for the entrance, but perhaps one compensates for the other, especially since two teams have already been seen with this feature.
Also note how the ground surface is shifting back and up around what is likely the lower side impact bracket (red arrow), as the side pillar itself is very high off the ground.

Looking at the ground from another angle, we can see that Alfa Romeo is the first to include an “edge spoiler” in the space allowed in the background. The leading edge of this streamlined device is lifted off the ground surface, leaving only a metal brace to create a gap.
It’s also possible to see the rear section of one of the floor appendages from this angle, as the team appears to have oriented them in such a way that they can provide outward flow.
At the back of the bottom we see another solution that existed with the previous regulation, with a slot added and the geometry of the floor subsequently altered to influence the path of the airflow (red arrow).
Alfa Romeo is the second team to opt for push-rod rear suspension, and has moved the interior elements higher to make room for the now much larger diffuser.

The Swiss outfit has also returned to the single-blade-style rollhoop design it used in 2018 (above). This is a design where the airbox inlets are moved away from the blade to improve flow into them and down the car.
