Triplex Suspension System

Handling, stability and comfort all in one

When the rear hood of a Koenigsegg opens, you will notice a third damper, stretching from side to side across the top of the engine bay. The word written across its mid-section carbon fiber cover denotes its name – Triplex – and it’s yet another Koenigsegg innovation.


What it combats

The primary reason for the ‘Triplex’ third damper is to provide an anti-squat element to the suspension setup. Squat is what happens when you take off under hard acceleration – the rear end of the car wants to dip down, or squat, because of the physical forces placed on it.

Squat provides good rear-wheel grip on hard acceleration, but it can compromise handling at the front end of the car and therefore, it must be managed. This is the scenario under which Triplex was invented.

When you take off under full power, the rear end wants to squat down, which means the rear wheels want to ‘rise’, compared to their usual position in relation to the chassis of the car. This action compresses the rear dampers as the rear wishbones try to lift.

How it works

The Triplex rear damper acts against this tendency, providing resistance against ‘squat’ (both dampers compressing at take-off) but doing nothing during regular single-sided compression of the dampers (e.g. during cornering). The Triplex damper also counteracts the anti-roll bar when driving straight on an uneven road, but does not work against it while cornering. This actually increases comfort and grip.
