The Koenigsegg Automated Twisted Synchrohelix Actuation Doors - KATSAD for short - really comes into play with the B-pillar-less four seater Gemera, as it makes the ergonomics amazing compared to any other two door four seater. Instead of having a normal long door - hopeless for parallel parking - while not really letting out the rear seat passengers in any acceptable fashion - the KATSAD with no B-pillar lets all four passenger exit simultaneously, in a full parallel parking situation. Unheard of practicality, made possible by typical Koenigsegg ingenuity combined with brave execution. #Koenigsegg #Gemera
