Aerodynamics.  A quick glance at this year’s cars could lead you to believe they are pretty much the same as their predecessors. That’s because most of the changes to the regulations concern the underside of the car, aimed at totally eliminating the unpleasant porpoising phenomenon. The cars thus sit higher, because the minimum height of the plank – the central section of the floor – is increased by 10 mm, while the outer edges of the floor are raised by 15 mm. Importantly, the maximum permitted deflection of these parts has been reduced to 5 mm. When it comes to the aerodynamics at the front end, there are new restrictions to the front wing in the area of its four profiles and the outside vertical edges of the endplates. The rearview mirrors must now be a third larger.

Safety.  One of the key areas of change concerns the roll hoop, which is stronger and features an increase in height from 900 to 950mm (measured at the reference plane) and with a curvature of at least 20 mm. The roll hoop must now withstand a much greater force than last year to prevent it from failing in an accident.

Minimum weight. The minimum weight of the car drops from 798 to 796 Kg, which is a small reversal of recent changes, given that between 2014 and 2022 the car’s weight increased by 107 Kg.

Tyres.  The 2023 Pirelli range has been developed in close consultation with teams and drivers. The tyres feature a new construction, which allows them to run at lower pressures, improving front end grip thus counteracting understeer. It’s an important change that will have an effect on car balance and on tyre management during the race. Apart from the new construction, Pirelli has also introduced a sixth compound that fits between the C2 and the original C1, this now being known as C0.

With relatively few changes to the technical regulations it’s clear the theme for the 2023 Formula 1 World Championship is stability.
