E-mobility is the buzzword of our time. People should be mobile, machines eh. Whether it is public transport on wheels or rails, municipal vehicles, other commercial vehicles or airport apron vehicles, the call for e-vehicles is getting louder all the time. Their climate friendliness, due to the avoidance of CO₂ emissions, as well as their environmental compatibility in terms of reduced noise emissions, make them fit into the picture of our environment much better than their diesel or petrol-powered counterparts. To ensure that the environmental bonus does not come at the expense of efficiency, REFUdrive relies on consistent further development of its technology.
