Aerodynamics

Rear wing

Facts:

- a wing shaped aerodynamic device attached to the body of a car

- like an airplane wing it creates a lift force by lowering the pressure of the air flowing along the longer side of the wing therefore creating a suction effect

- unlike the airplane wing the longer side of the car wing is the bottom one

- therefore the lift force aims downward

- it compensates for the lift force created by the same effect thanks to the natural shape of a car (the top has longer surface than the bottom) and increases traction

- it works at higher speeds only

Rear spoiler

Facts:

- a small aerodynamic device attached close to the body of the car

- helps to lead the air off the rear of the car

- reduces the low-pressure zone behind the car lowering drag and instability

- does not increase traction by downward force

- makes the car look better (sometimes)
