Ground effect consists of reducing the space between the floor of an F1 car and the asphalt to create a low-pressure area under the car, thus increasing the speed with which the air circulates and creating a greater downforce, even higher than that generated by the wings.
Ground effect is a concept with its roots in flight, but it’s currently used in F1 to glue the cars to the track – and its use in racing can be traced all the way back to the 1920s.
Why was car ground effect banned?
F1 banned the ground effect in the 1980s because the FIA

felt that the ever increasing cornering speeds were becoming too dangerous. If the ground effect was disturbed, cars would lose so much of their downforce at one time that it just became too risky, and the ground effect was banned in 1983.
The 2022 F1 season welcomed a new wave of regulations designed specifically to aid close racing and overtaking. This was facilitated by the legalising of ground effect aerodynamics, a method of creating downforce not seen since it was banned in 1983 for safety reasons.

Do any road cars have ground effect?
The car which made that breakthrough was the Lotus 78 of 1977, which ushered F1 into the era of ground effect. Forty years ago, the 78’s successor, the Lotus 79, became the first ground effect car to win the world championship, with Mario Andretti

When was active suspension banned in F1?
Active suspension was banned in F1 ahead of the 1994 season, as part of a push to cut back on driver aids that were dominating the sport.
When was ground effect introduced in F1?
The ground effect first came into F1 through British Racing Motors or BRM in 1968, when their engineers Tony Rudd and Peter Wright carried out several experiments on cars in a wind tunnel. Although they did not use a “true” ground effect car, they still managed to create a basic prototype.
Ground effects was another innovation brought to F1 by Colin Chapman’s Lotus team. It was borne of an idea of making the entire car function as one giant wing to increase downforce.
Will 2022 F1 cars have ground effect?
2022 is the first time teams can use ground effects since the 1980s after it was banned. The sudden loss of downforce that came when the ground effect failed – with a bump, a nudge or a rough piece of track – led to drivers losing control and sometimes hurtling off the track.
Did F1 cars porpoise in the 80s?
Ground effects were largely banned from Formula One in the early 1980s until 2022, but Group C sportscars and other racing cars continued to suffer from porpoising until better knowledge of ground effects allowed designers to minimise the problem.
How did Mercedes solve porpoising?
The team’s boss, Toto Wolff, revealed that the reason for this, is because the porpoising issues were all but eradicated. By lowering the height of the car, the bouncing motions have been decreased, making the cars a lot safer, and the drivers a lot more comfortable.
Why are F1 cars not equal?
Formula 1 Cars Are Very Different From Each Other
Designers have some leeway within the rules, which creates the unique performance each Formula 1 team delivers. There are ten teams, and each performs at different levels depending on where they are racing in the world.
Why is it called porpoising?
Porpoising comes from the humble porpoise, a sea-dwelling mammal that’s known to bob up and down on the surface of the ocean as it swims along.
Running the cars lower to the ground more effectively seals the floor and increases the downforce but also increases porpoising. Raising the ride height bleeds away downforce and therefore decreases cornering speeds and increases lap times.
What causes porpoising in a car?
What Causes Porpoising in an F1 Car? A key component of ground effect in Formula 1 is the use of wind tunnels built into the underbody of the car, also known as Venturi tunnels.
How do you fix porpoising?
How to fix the porpoising F1.
Ride height setup: by increasing the ride height, the ground effect is diminished and the porpoising effect is weaker.
Suspension setup: another way to control the damping of porpoising is to modify the suspension and their stiffnesses.
How did Red Bull fix porpoising?
Red Bull are said to have accidentally counteracted the “porpoising” issue that has been caused by the new technical regulations. In sweeping changes to the cars, the downforce is now generated by aerodynamics underneath the car rather than on the chassis, and this is known as ground effect.
Does porpoising affect performance?
In general, put simply, the higher the cars are off the ground, the worse their performance will be. The Mercedes W13

Do hydrofoils stop porpoising?
In addition to helping your boat get up on plane faster and more efficiently, an outboard motor hydrofoil or stern drive hydrofoil from Hydro-Shield can also help solve your porpoising problem.
How far below the transom should the prop be?
Industry standards dictate that for short shaft engines the transom height should be 15″. A long shaft engine requires a height of 20″ and extra-long shaft engines will need a transom height of 25″.
