Abstract
Use of non-metallic materials is increasing, with the need to produce lighter, greener and more economical vehicles. This, compounded by the ever-escalating electronic content of vehicles for telematic and safety critical systems, increases the importance of safety and electromagnetic immunity of a vehicle resulting from the use of non-metallic body panels.

Use of statistics has demonstrated that increases (in current induced onto the vehicle harness) up to 10dB can be observed, resulting from the use of non-metallic body panels. However these are no more significant than variations presently found between identical production vehicles.
