Taking into account the repair stages of the BMW workshop information system, the body repair work in the Technical Qualification is divided into 3 repair levels. Each of the 3 Body Repair Levels includes certain prerequisites in terms of the qualifications of the employees and the workshop equipment.
The special characteristics of the add-on body parts and the materials used in the outer body skin are described in this chapter. However, the basic functions of the roof and the outer body skin components made of plastic are the same as on other current BMW models. For this reason, these components will not be described in detail here.
Outer body skin materials
G30 Outer body skin
As was already the case with the F10, the doors, hood and front side panels are made of Aluminum.
In addition, the trunk and the roof of the G30 is also made of Aluminum, which contributes to the significant weight reduction.
The bumper panels at front and rear as well as the side sills are made of plastic as before. However, further development of this material made it possible to reduce the density and weight.
