BMW revealed a number of technical details about the 2016 BMW 7 Series last month. The company said that the next generation 7 Series’s body structure makes use of technologies borrowed from the i sub-brand models, which makes it much lighter than the outgoing generation.
Carbon-fibre-reinforced plastic (CFRP) has been extensively used in the structure of its passenger cell. The whole body structure isn’t made of CFRP though; lightweight material has been used very strategically. The revamped model’s chassis is made from a mixture of carbon fibre, aluminum and high-tensile steel. As a result, the 2016 7 Series is 130 kg lighter than the outgoing one.
Citing a conversation with an unnamed next-gen 7 Series project insider, a new report from Autocar suggests that BMW may use lightweight construction technologies from the all-new 7 Series for smaller models – the next-gen 5 Series and 3 Series being the more likely ones. The two volume models form a big chunk of the German automaker’s global sales and it will make them more efficient and better in performance while meeting future emission regulations.
Weight reduction of these models can also prove to be very fruitful in making their electrified versions successful. In December last year, the BMW Group announced that it is planning to offer plug-in hybrid electric versions of all its core-brand models. Significant weight reduction can aid to increasing of the pure electric driving range.
