How does ground effect work in F1?

When a car moves over the ground, the boundary layer on the ground becomes helpful. In the reference frame of the car, the ground is moving backwards at some speed. As the ground moves, it pulls on the air above it and causes it to move faster. This enhances the Bernoulli effect and increases downforce.

Is the 2022 F1 car slower?

Cars built to new technical regulations for the 2022 Formula 1 season could be as little as half a second slower than their predecessors despite being much heavier. Upper aerodynamic surfaces will be simplified, while teams are being given greater freedom to generate downforce using their cars’ floors.

Why did F1 ban ground effect?

Ground effect was eliminated by regulation changes partially for 1981 then more fundamentally for 1983 due to excessive cornering speeds and safety concerns. F1 and the FIA’s proposals for 2021 also include removing the requirement for Pirelli, F1’s tyre supplier, to produce high-degradation rubber.

Why do F1 tires break so easily?

It’s easy to spot from the board camera during the race as an uneven patch on the tire. If the situation is reversed and the outside surface is hotter than the inside, lateral forces in the corners of the circuits will cause the outside to tear off into small pieces.

Why do F1 cars accelerate slow?

F1 cars accelerate from 0 – 60mph in roughly 2.6 seconds. This might seem slow given their top speed, however as a lot of their speed comes from the aerodynamics (which works better the quicker the car is going), they can’t unleash full power from a standing start.

What diameter are F1 wheels?

But the Abu Dhabi Grand Prix doesn’t just mean the end of an exciting year of racing—it also marks the end of an era as the sport prepares for a radical change to its tires. For decades, F1 cars have run on 13-inch wheels, wrapped in tires with high-profile sidewalls.
