A core element of BMW EfficientLightweight in the BMW 7 Series is to use an innovative mixed construction for the body. Using steel, aluminium and in particular innovative carbon fibre (carbon fibre–reinforced plastic, CFRP) not only meets all the requirements for driving dynamics and comfort, but also sets whole new standards in the luxury class.
At the centre of the holistic concept stands the Carbon Core, showcasing its weight advantage compared with steel in the torsional stiffness of the body. Together with a consistent weight reduction from the broad concept down to the smallest detail, this achieves an almost perfect 50:50 axle load distribution and drops the centre of gravity even further. In short, this spells out the ideal car DNA for maximum driving comfort while still boasting an improvement in handling and agility as well as low fuel consumption and emissions.
In this way, BMW EfficientDynamics intelligently connects the ultimate in efficiency with maximum driving dynamics, and demonstrates its technological capabilities in the field of innovative lightweight construction.
