Why does the Ultima not need roll down windows?
Simply because the doors open upwards unlike front hung doors on ordinary cars that are forced to have some form of opening access. Tolls and the like are simple to access in this way and more fun than boring windows. Another benefit of the Ultima gas assist door opening system is that they can be opened in tight parking spaces allowing driver and passenger access unlike cars with ordinary doors. Perhaps the most important reason for the 3/4 opening doors is that it allows for a huge 12″ crumple zone to the side of the driver and passenger offering superior protection over front hung doors.
