Within the last years the development of car technologies in the field of electrical propulsion systems generates a real hope for a trend reversal towards environmentally friendly vehicles. However, battery electric vehicles (BEV) are still not competitive with conventional cars: Therefore, electric vehicles with a reasonable sized battery and a range extender (EREVs) could be a sustainable (bridging-) technology to fulfil the user needs. Within the paper the development of future scenarios of electromobility (EREV, BEV) is described. They take into account following aspects under consideration of country specific conditions: (a) mobility behaviour including long distance travel, (b) socio-geographic framework, (c) socio-demographic framework, (d) transport policy framework, (e) society values and public opinion, (1) political-economic framework and (g) technical framework. For each factor, an optimistic upper limit scenario, a pessimistic lower limit scenario and a most likely scenario is defined. As a result the market penetration rates for EREVs will be calculated.
