Dihedral synchro-helix actuation doors

Type of door with hinge mechanism

The dihedral synchro-helix actuation door system is a type of door with a hinge mechanism which allows the doors to rotate 90° by sweeping outwards and upwards at the hinge. It was designed and developed by Christian von Koenigsegg on behalf of high-performance sports cars manufacturer, Koenigsegg Automotive AB. It was conceived as revolutionary when it made its debut on the CC prototype (1994–2000). The first production car to be fitted with these doors was the Koenigsegg CC8S (2002–2003). The door's primary intention was to open high enough to avoid most curbs, but low enough to avoid garage ceilings. It also minimizes the space taken at the side of the car while opening the door, which makes it easier to open the doors while being parked on tight spaces with another parked car at the side. The Koenigsegg Regera was the first car to be equipped with Autoskin, a feature which allowed this mechanism to be completely motorized by making the door sweep automatically by pressing a button. These doors are found on all Koenigsegg cars which includes:Koenigsegg Agera Koenigsegg Agera Final Koenigsegg Agera R Koenigsegg Agera RS Koenigsegg CC Koenigsegg CC8S Koenigsegg CC850 Koenigsegg CCR Koenigsegg CCX Koenigsegg CCXR Koenigsegg CCXR Trevita Koenigsegg Jesko Koenigsegg One:1 Koenigsegg Regera Koenigsegg Gemera Ulf Sensor GTR Peugeot HR1 Mercedes-Benz F200 Renault Twizy
