Body in white or BIW refers to the stage in automotive design and manufacturing at which a car body sheet metal components have been welded together. BIW is defined as the stage prior to painting and before moving parts (doors, bonnets, tailgates and hatch back doors, as well as bumpers), the engine, chassis sub-assemblies, or trim (glass, seats, upholstery and electronics) have been assembled in the frame structure.


While aluminium has been able to conquer the drive train, heat exchanger the chassis, body and general equipment and fittings areas of lightweight vehicle build construction. The key issues have revolved around optimising the design to exploit the advantages of aluminium and, at the same time, be cost-effective. The body-in-white (BIW) accounts for about 27% of the weight of the entire average car.

Advantage of Automotive Body In White:

Reduced vehicle mass directly reduces fuel consumption and CO2.

Further mass reductions and lower fuel consumption are generated in a multiplier effect by enabling, for example, smaller engines, wheels and brakes.

A lower vehicle center of gravity improves handling and safety.
