Often, the first interaction a person will have with a vehicle is opening the door. As first impressions are everything, it is very important to not let the action of opening the door detract from the look and feel of the vehicle. A pleasurable door opening operation starts with a well-designed hinge.
Saint-Gobain engineers have researched into the factors of a door hinge that affect the perceived quality of the vehicle. Using this research they are able to design bearings that are the solution to the need for consistent feel, not just the first time the door is opened, but every time.
