Why do race cars have huge rear wings?

Answer: Push car down for better grip

Stabilize car during turns only — Wrong. Wings do help in turns, but they work constantly—they push the car down at all times when moving, improving grip for acceleration, braking, and cornering.

Push car down for better grip ✓ — Correct! Rear wings work like upside-down airplane wings. They create downforce (aerodynamic pressure pushing down) that presses the car onto the track. This increases tire grip, allowing faster cornering, braking, and acceleration without losing traction.

Cool the engine from behind — Wrong. Wings don't cool engines. They generate downforce—aerodynamic pressure that pushes the car down, increasing tire grip for better performance.
