New BMW series boasts CFRP-derived weight savings


Extensive use of carbon-fiber-reinforced plastic (CFRP) in the structure of the passenger cell, of the new BMW 7 Series means the line-up will tip the scales up to 130 kg lighter than the outgoing generation of models.

At the heart of the series is a body structure with a “Carbon Core” based on the transfer of technology from the development of the BMW i hybrid models. The use of CFRP – whose material properties lend themselves to use in the passenger cell areas exposed to heavy loads – increases torsional rigidity and strength. The configuration of the sheet metal elements can be adjusted accordingly, allowing body weight to be significantly reduced according to BMW.
