Concept EV rolled out on all-plastic wheels


Daimler (Stuttgart) and BASF (Ludwigshafen) have developed a new concept vehicle that combines both companies' ideas for electric mobility. One of many industry firsts in the vehicle is the use of polyamide (PA) in the wheels. The smart forvision will have its world premiere at the 64th International Motor Show in Frankfurt later this month.

The partners have succeeded in combining no less than five automotive world premieres in the new concept vehicle. Transparent organic solar cells, transparent organic light-emitting diodes, the all-plastic PA wheels, new lightweight body components and infrared-reflective films and coatings all help to reduce the vehicle's energy consumption and so increase its range and practicality.

Besides the use of Ultramid PA in the plastic wheels that saves 30% weight compared with metal, fiber-reinforced plastics have been employed in load-bearing components in the vehicle chassis to further reduce weight and minimize the drive energy requirement.
