WHAT'S CHANGING IN THE BIGGEST EVER RULES OVERHAUL FOR F1'S 2022 CAR?

Welcome to 2022, the year in which Formula One hopes to transform itself into a far more open and competitive championship through a slew of rule changes. Here's another chance to read our what's new guide.

Last year, ahead of the British Grand Prix, Formula One unveiled its promotional car for the new 2022 regulations at Silverstone.

The regulations were originally planned for the 2021 season, but were delayed due to the impact of the COVID-19 pandemic.

The event was effectively a relaunch rather than the unveiling of something brand new, as teams have long been working on designing cars to the already-published rules, and F1 had originally launched the package to the public in late 2019, when it was scheduled to arrive in 2021.

What's in store for 2022 is arguably the most significant change in technical rules in F1.

The goals are straightforward: build cars that are suitable for F1's cost-cutting era while also being more raceable on track. That means they should be less prone to turbulence and thus able to run closer together, resulting in more overtaking and excitement.

Here's a rundown of the new F1 rules & regulations for 2022:

AERODYNAMICS

 *In place of the current flat floor, a ground-effect floor with two long tunnels will ensure that a greater proportion of the car's total downforce is generated from the underbody, resulting in a much cleaner wake and an aero platform that is less sensitive to wake.

 *The upwash of air from the floor is intended to be much higher, giving it more time to dissipate its energy before falling on the car behind.

*Front wing and endplate have been simplified. The four-element wing is attached directly to the nose and transitions into a much-simplified single-piece endplate, which is not standardised but highly prescriptive. It will be far less wake sensitive than current designs.

* A prescriptively shaped rear wing with an incut wrap-around connection between the main profile and the lower beam wing, effectively removing the rear wing endplates and the strong vortices they generate.

* While the bodywork geometry of the car and engine cover will still vary from team to team, they will be defined within quite tight templates that seek to create as clean and unsensitive airflow as possible.

* Restriction imposed on brake duct shaping for downforce generation.

* The combined effect demonstrated in simulation that the following car retains 86 percent of its maximum downforce when one car length behind the car in front, compared to the current car's 55 percent.

SUSPENSION/WHEELS\s

* The move from 13-inch to 18-inch wheelrims necessitates the installation of new low-profile Pirelli tyres. The goal is for these to be less temperature-sensitive, allowing drivers to push hard throughout stints while still exhibiting a performance drop-off to keep strategy interesting.

* The extended mounting points pioneered by Mercedes and what was Toro Rosso that have since become de rigeur have been outlawed. As a result, the suspension must now be connected directly to the wheelhub.

* Hydraulic suspension is prohibited, so the stiffness can only be controlled by springs and dampers.

* Suspension-attached inerters are prohibited.

* To monitor tyre running conditions, a standard tyre pressure sensor will be used.

* Bargeboards are prohibited.

* Standardised flush wheel covers to eliminate the use of the wheel/axle to generate downforce-inducing airflows.

* Front wheel deflector to reduce airflow 'outwash'

CLASSIFICATIONS OF PARTS

As part of an effort to allow cost savings on parts that are not deemed to be performance differentiators, Formula 1 components are now divided into five different designations.

* The listed parts are the components that a team must design and own the intellectual property for. This includes the monocoque as well as any non-specified aero surfaces.

* Standard supply components are those designed and manufactured by a specific supplier. This includes components like the fuel pump and tyre pressure sensors.

* Transferrable parts, such as the gearbox and hydraulics systems, can be supplied from one team to another.

* Prescribed parts are those that teams build on their own but to a specific specification.
