Get in and off you go with efi!


An algorithm calculates the shortest route and combines this with simultaneous travel requests from people whose routes are on the same route. In this way, all passengers are brought to their desired destination as quickly as possible.


The well-known electric vehicles of the "London Cab" type are used. People with restricted mobility can also get into the vehicle comfortably via a ramp, with large grab handles to help you! A panoramic roof and the pleasant driving experience ensure a comfortable journey. A total of up to 6 passengers can be accommodated in the vehicles.
