Carbon Core of next-gen BMW 7 Series helps reduce sedan’s weight by up to 130 kg; remote control parking

Due to the BMW EfficientLightweight strategy, the new BMW 7 Series line-up will weigh up to 130 kilograms (287 lbs) less than the outgoing generation of models. At its heart is a body structure with a Carbon Core based on the transfer of technology from the development of the BMW i models. The use of CFRP for structural elements of the passenger cell based on hybrid construction with ultra-high-strength steels—such as the B-pillars—increases both the overall strength and the torsional and bending stiffness of the passenger cell. To this end, the configuration of sheet metal elements can be adjusted as required, allowing for a significant reduction in the weight of the body.
