A Race Car, in fact almost all cars are designed in a way to avoid lift and stick to the ground at all times. We wouldn't want cars just suddenly rising up due to high velocity. So keeping in mind the Bernoulli Principle scientists designed cars in a way completely opposite to that of an airplane. A race car employs Bernoulli's principle to keep its rear wheels on the ground at all times while travelling at high speeds. A race car's spoiler—shaped like an upside-down wing, with the curved surface at the bottom—produces a net downward force, thus keeping the car to the ground.
