As Formula 1 enters it’s 72nd season, with it comes a new era of rules and regulations for the cars. The sheer overhaul and direction of the rules has never been seen before. Normally the rules are designed to slow the cars down but this time they take a more positive approach. They take onboard lessons learned from the past but in bid to produce better racing into the future.
What’s in the new rules?
New 18-inch Tyres
New Front and Rear Wings
A much more, sleeker, aero efficient design.
The new 18-inch tyres are the biggest tyres that ever been seen in Formula 1, certainly contrasts from Tyrells 10 inch 6-wheeler in 1976.
In previous years Formula 1 has had smaller, 13 inch rims. Big chunky tires which were a perfect look for racing but among one the drivers complaints were the tyre’s inconsistencies and their snap of overheating. But Pirelli’s new low-profile 18 inch tyre aims to address this.
“Drivers were asking for less overheating, less degradation; they want to push on tyres, they want to fight on track, we decided and we agreed with the FIA and the teams to follow these directions. So we had to design a new profile, new construction, optimise the footprint, design a new range of compounds - a completely new product with a new approach” Pirelli F1 Boss Mario Isola telling during the 2022 launch.
The new construction makes the tyre far more durable, with less overheating and a wider working range. This wider range gives the cars more time on track, and in turn produces more on-track action thus producing more overtakes.
Partnering the striking 18 inch tyres are the over-wheel winglets and wheel covers, last seen in Formula 1 in 2009. These two moves are essentially aero-damage control for the cars.
The wheel covers will lower the complexity of the cars, avoiding the chaotic aero wake which they usually give off. Due to the wheel covers being heavily mandated there’s doubt the teams will have much influence over the design, giving hope new covers will play their part.
New Front and Rear Wing and Ground Effect
Continuing the objectives of the 2022 rule changes, the front and rear wing saw a radical revolution.
The new front wing completely banishes the Y250 vortex. Prior to the 2022 regulations, there was a gap in the front wing between the nose and wing elements, this gap generated the Y250 vortex. This vortex accelerated the airflow through the car, reaching the old bargeboards and attempting to push air away from the car as far as possible. Despite the vortices advantages; it produced turbulent downwash for the car behind, making it hard for the car behind to follow.
The new front wing eliminates the 250mm gap, this will keep the airflow inside the car, reducing the manic wake created by the cars letting the car behind get a fair a chance to overtake.
The new rear wing is the front wings partner in crime.
Prior to the 2022 regulations the cars were always designed to push air up, to then in turn push the car down. This is called ‘over body’ downforce. To accommodate this, endplates were used on the rear wing. Whilst they boosted the efficiency of the car, accelerating the car’s airflow, they were the biggest culprit for dirty air.
The sharp edges on the rear wing creates manic vortices that disturbed the car behind. As you can see, the 2022 rear wing takes a entirely new approach; removing the sharp edges and opting for a more curved shape.
The new curved-shape rear wing will, using the newly designed floor and diffuser, eject dirty air above any following cars, reducing any loss of downforce to below 18%.
As the cars begin to rollout onto the Circuit de Barcelona-Catalunya, the 2022 Formula 1 seasons begins.
