Due to the increasing number of people in cities, there is a need for affordable individual transportation to complement public transport. Limited space together with the need for a significant reduction of pollution will lead to new mobility concepts in the near future. The aim of these concepts is not replacing the car itself but to apply and modify this kind of transportation in order to satisfy people’s needs in big urban areas. For this purpose, electrical powered concepts may be used. Due to the limited energy density of current battery concepts, a significant weight reduction has to be achieved in order to guarantee performance and range requirements. This weight reduction can not only be reached by using cost intensive lightweight materials itself. In order to develop an affordable urban concept, the requirements for this kind of vehicle have to be adjusted in comparison to conventional cars. As a first step, a demand analysis is carried out, which is the starting point for the development of a new urban mobility concept. The so called “E3W” combines the advantages of a two-wheeler with those of a four-wheeler, resulting in a lightweight and compact vehicle. This concept, placed in the L5e homologation class, accommodates space for two persons with luggage and guarantees wind and weather protection. The overall measures of this vehicle are significantly smaller compared to current compact cars and therefore allows for better use in areas with limited space. In order to reach an operating range between 60 and 100 km, a short fiber reinforced thermoplastic body structure is chosen, combining good weight specific mechanical properties and low production costs. This body structure also provides the body cover, which leads to a high integral construction. Additional pultrusion glass fiber reinforced plastic (GFRP) profiles are used to reinforce the chassis. Finally, two prototypes are built to investigate the driving behavior and the suitability for daily use.
