Racing cars use upside-down wing physics to glue themselves to the road
To keep a high-performance vehicle from lifting off like a plane, engineers use invisible air pressure to generate the weight of a grand piano.
While airplanes use wings to lift away from the earth, a Porsche 911 GT3 does the exact opposite by treating the air like a heavy blanket. At speeds of 285 kilometers per hour, the car's active rear wing and underbody channels generate 400 kilograms of downward force. This invisible weight effectively glues the tires to the asphalt, allowing the car to take corners at speeds that would otherwise send it sliding into a barrier. The car even uses hydraulic flaps that can change their angle in just 0.2 seconds, mimicking the drag reduction systems found in Formula One racing to balance speed and grip on the fly.
