Why Does a Car Feel Floaty at High Speeds?

[DeWyatt]

There are several reasons why a car may feel floaty at high speeds: 1. The lower the chassis, the more floaty the car feels at high speeds, while a higher chassis provides more stability: Vehicles with higher chassis have stiffer suspension support, offering better stability, and the steering wheel feels heavier, reducing the sensation of floatiness at high speeds. 2. Aerodynamic design factors: This includes how streamlined the car's design is, the strength of air resistance, and the level of friction between the tires and the road. 3. The position of the car's center of gravity: The height of the center of gravity from the ground acts as a lever arm. According to the principle of leverage, if the force applied is equal, a longer lever arm results in a greater torque. When the centrifugal torque exceeds the gravitational torque, the car may roll over. Even if the centrifugal force isn't strong enough to cause a rollover, it can still create unequal force distribution on the left and right tires. One side may experience increased contact area, while the other side's contact area decreases, significantly affecting the car's handling stability and potentially leading to loss of control.
