How does an F1 rear diffuser work?
The diffuser acts as an expansion chamber to manage the air as it exits from underneath the car and reintegrates it with higher-pressure ambient air. Smoothing this transition reduces turbulence and drag in the car’s wake and improves airflow under the car.
What is an F1 diffuser?
A diffuser serves to eject air out from the underside of the car. This pulling action increases the velocity of the air below the car, so that the more slowly moving air above the car will push the car into the ground.
Does rear diffuser do anything?
The main function of a car rear diffuser effectively increases the vehicle’s downforce and increases the car’s grip on the road surface and reduce the aerodynamic drag.
Do F1 cars have diffusers?
The diffuser – the final part of the floor at the rear of the car – is a pivotal part of any F1 car, and was one of the keys to Brawn’s 2009 World Championship success when they implemented the ingenious ‘double diffuser’ – but this year the rules around the device have been changed, as part of a push to reduce the …
Why do diffusers have strakes?
Strakes serve two main functions: keep tire squirt from the diffuser tunnels and to be vortex generators. Tire squirt can be minimized by using strakes to reduce the amount of tire wake making its way into the diffuser tunnel. Reducing the airflow from the wheels increases diffuser performance.
What do bargeboards do F1?
Function. Aerodynamically, bargeboards act primarily as flow conditioners, smoothing and redirecting the turbulent or “dirty” air in the wake of the front wing, the front suspension links, and the rotating front wheels.
Does diffuser suck air?
When a diffuser is used, the air flows into the underbody from the front of the car, accelerates and reduces pressure. There is a suction peak at the transition of the flat bottom and diffuser. This transition is where the lowest pressure generally is located and is called the throat of the diffuser.
Does a rear diffuser make your car faster?
The primary purpose of a rear diffuser is to efficiently increase the downforce of a vehicle. This helps increase grip and reduce aerodynamic drag.
What is the F1 Halo?
The Halo is a protective barrier that helps to prevent large objects and debris from entering the cockpit of a single-seat racing car. There are specific rules for its construction, and the device is manufactured by three approved companies for the F1 teams to then add to their racing cars.
What is porpoising in F1?
Porpoising is when a Formula 1 car bounces up and down – a phenomenon caused by an increase, then a sudden decrease, of downforce. It is traditionally associated with ground effect cars, with teams working hard to get on top of the issue with the new breed of Formula 1 machines.

What is the purpose of diffuser in F1 cars?
‘The key role of the diffuser on a modern racecar is to accelerate the flow of air under the car, creating an area of low pressure, thus increasing downforce.’ What this actually means in real world terms is that the shaped piece of bdywork at the rear of say an F1 car , draws the air out from under the car.
