Currently the largest aluminium structural casting at Mercedes-Benz, BIONEQXX is the major structural component at the rear end of the VISION EQXX – the rear floor. It was developed in-house by Mercedes-Benz using entirely digital techniques and a software approach that is utterly unique within the automotive sector. The result is optimum functionality packaged within the compact dimensions of the available space. Furthermore, the team created this impressive and manufacturable one-part casting in just four months.

Taking their cues from organic forms, the development engineers sought to use material only where necessary for structural function, i.e. where loads are exerted. In line with the laws of nature, where there is no load there is no need for material.

The most important of the structural criteria is the need for very high stiffness and excellent crash performance. The beauty of the one-part BIONEQXX casting is the ability to pair this with functional integration within an extremely lightweight single component rather than an assembly of multiple parts joined together.
