Formula One race cars may not have much in common with ordinary road cars, but they're still bound by the same laws of physics. That means like all cars, F1 cars need suspension to keep their wheels in contact with the pavement, and to absorb bumps. While F1 suspension performs a similar function to road-car suspension, the hardware is different. Current F1 cars use pushrods, pull rods, and torsion bars—things you won't find in most road cars.
The main purpose of the suspension is to connect a car to its wheels. This may sound relatively trivial; however, it does need a complex system of different components because moving a heavy object like a car at high speeds creates several challenges. On a road car, the suspension has two main functions - ride and handling. Ride refers to the way the vehicle deals with changes in the surface of the road, how it copes with undulations, bumps, kerbs, potholes, changes in camber and the like.
