The key elements of the Koenigsegg suspension system are the double wishbones. They are A-arms made of precision welded chromemolybdenium steel tubes. Construction and choice of materials were determined by the necessity of low weight and superior strength. Their proportions are customized to suit the specific demands of this high-speed machine. The Koenigsegg A-arms are considerably longer than those of competing supercars. Their dimensions are similar to those used in Formula One racing cars, which has the benefit of less trackwidth deflection during suspension movements. This means a more controlled and comfortable ride in combination with better handling, less roll and higher cornering g-force, which can be as high as 1.3 G in a Koenigsegg.

A pyramidal lever construction directly connects the A-arms and the shock absorbers, which allows the shock absorbers to be mounted inside the car. This solution optimizes packaging aerodynamics and creates a progressive movement, which eliminates the need for progressive springs, and thereby provides far better control of the suspension setup. Flambloc bushings are used for mounting the A-arms to the chassis subframes. The Flambloc bushing has the advantage of friction-free movement on the axial plane, ensuring extremely low hysteresis levels compared to normal silent blocks. This further improves the good handling and road holding of a Koenigsegg.
