The engine cover of the Ferrari SF21 presented in this manner gives us a clearer indication of the shapes used to enclose the internal components. Note how the sidepod ramps down to where the floor would be and how the bodywork haunches over the coke bottle region to form the cooling outlet above it.

A great shot of the Alpine A521 shows us the pipework used to carry airflow collected by the main brake inlet that’s dispatched out of the wheel face and we can see how the bargeboards are made up of several layers.

An interesting view of the Alfa Romeo C41’s nose and front wing – note the channel inside the nosecone which feeds the ‘S’-duct outlet and is fed air from inlets at the front of the structure.

Here’s another angle of that region on the Alfa Romeo C41’s footplate, which shows how the surface is designed to encourage the airflow to move between the upper and lower surface, while also offering support for the flow over the top thereafter with an outwardly-angled fin.

The top-down shot of the Alfa Romeo C41 gives us an idea of how far the trailing edge of the floor is from the tyre. In recent years, teams have tried to get the floor as close as possible to the floor but this year it appears that may not be the route to take.

A look at the SF21’s rear end as the team conducts pitstop practice. Note the use of a fully tapered floor, with a trio of fins mounted midway along the floor to help push the airflow across the rear tyre, while the cluster of fins ahead of the rear tyre help to pitch the flow in the gap between the edge of the floor and tyres’ sidewall.

Alpine’s two front wing options on the trolley as they’re wheeled to scrutineering. Note the top of these two is the new version which features a new endplate (no notch in the upper rear corner), a new design for the inboard section of the wing flaps, a new position for the inlet on the side of the cape and a new flap/slot on the edge of the cape.
