2022 F1 Rule Changes in a nutshell.
The 2022 rule changes are intended to have the cars suitable for F1’s cost cap era but also be more ‘raceable’, less prone to turbulence and able to run closely and potentially easier overtaking.
The cars will look very different, most obvious are the 18 inch wheels with low profile tyres and wheel covers. Less obvious are front & rear wing designs and other aero design items.
Cars will get a downforce from a new ground-effect floor. This is two long tunnels in place of a flat floor & barge-boards, this gives a less turbulent rear wake and the up-wash of air exiting from the floor is higher and gives it time to dissipate faster.
Front wing will be a more simple four-element attached directly to nose and transitioning into a simplified single-piece end-plate.
Rear wing will be shaped with a round profile wrap-round connection between the main wing profile and the vertical supports. This removes rear wing end-plates and the strong vortices they shed.
18-inch wheels and low-profile Pirelli tyres. The intention is to be less temperature-sensitive allowing longer periods of hard racing.
Flush wheel covers standardised to prevent the wheel and axle used for down-force creation.
Front wheel deflector to limit airflow ‘outwash’.
Suspension must be attached directly to the wheel-hub .
Hydraulic suspension no longer permitted and only the spring/damper units can control suspension stiffness.
A standard tyre pressure sensor will be used to monitor the running conditions of tyres.
The 1.6-litre V6 turbo engine design remains unchanged. However the power units will be formally homologated at the start of the season and frozen up to the end of 2025.
At least 10% of the fuel must comprise “advanced sustainable ethanol” (E10)
