Dihedral synchro-helix doors

Dihedral synchro-helix doors

Sports cars typically have large doors to help with ingress and egress. Large doors mean plenty of space is needed to open them without hitting another car.


Companies have tried different solutions over the years, with varying degrees of success. Scissor doors open high and can be difficult to reach when the occupant is seated. Likewise, gullwing doors that are hinged from the roof can open too high for many.


Koenigsegg’s dihedral synchro-helix door mechanism was revolutionary when it was first conceived, and it remains unique in the automotive industry to this day. The door motion allowed by this hinge mechanism – sweeping outwards and upwards at the same time – is every bit as practical as it is beautiful.

Elegance in experience

The door opens high enough to avoid most curbs, but low enough to avoid garage ceilings. It also minimises the space taken to side of the car, which makes opening a large, sports car door into the side of another parked car a thing of the past.


Through the creation of the Koenigsegg Regera, the mechanism has been fully robotized. The door sweeps open automatically at the press of a button, bringing a heightened sense of elegance and theater to the beginning of every new journey.
