This Vision Vehicle has been designed according to circular economy principles. The aim is to achieve 100% recycled materials use/ 100% recyclability.
The all-solid-state battery in the BMW i Vision Circular is 100 per cent recyclable and manufactured almost entirely using materials from the recycling loop. It will achieve much higher energy density with significantly reduced use of the most valuable resources.
When it comes to the materials used, the focus with the BMW i Vision Circular is on recycled materials (“secondary first” principle) which can be disassembled quickly and easily at the end of the product life cycle.
The deliberate spotlight on disassembly is therefore an important aspect. The quick-release fastener for the wheels, seats and instrument panel, and a cord tie in the rear seat bench do most to showcase the detachability of material connections in aesthetically appealing form, creating a “joyful fusion”.
FEWER MATERIALS and MINIMIZING WASTE
- Mono-materials and clever new joining techniques for them which avoid the use of glue ensure optimum suitability for dismantling and sorting at a later stage. In order to minimise the amount of waste and offcuts, all components and materials will be manufactured to fit exactly using processes such as 3D printing. Any surplus material will be systematically fed back into the materials cycle.
- At the front end, the kidneys and headlights have been newly interpreted as a digital surface. In the future, digital design could make geometric variations in lights and bumpers redundant, helping to reduce the quantity of materials and tools required.
- Instead of additive trim elements, or badging of the sort currently used to signify quality, the brand logo is engraved on the front end and the vehicle badge is lasered on to avoid using extra add-on parts.
TYRES and WHEELS
- The slightly transparent tires are made from certified, sustainably cultivated natural rubber. Coloured, recycled rubber particles are added to the tyre compound for strengthening and create an intriguing terrazzo effect which purposefully highlights the reuse of materials.
- The wheel rims are designed for minimal materials use. Rim centres with maximum permeability provide brake cooling, while the more enclosed surfaces to the outer reaches of the wheels ensure the greatest possible aerodynamic efficiency.
- Another key measure in the drive towards sustainable urban mobility in- volves making intelligent use of the available real-time and long-term traffic data in order to maximise efficiency. If the sensor data and information gathered by the individual vehicles is shared with the entire fleet (with the users’ consent), all vehicles will benefit from the resulting swarm intelli- gence.
- Speed recommendations could be optimised to make better use of traffic light phases (“green wave”), traffic flows forecasted more accurately and periods of congestion minimised as a result of vehicles communicating with each other and with their environment. CO2 emissions caused by stop-start traffic or even searching for a parking spot would be reduced significantly across a large number of users.
