COST COMPARISON OF DIESEL VEHICLES (DV), HYBRID ELECTRIC (HEV) AND BATTERY ELECTRIC VEHICLES (BEV) AS TAXIS IN MAINZ
Road traffic and especially Diesel vehicles are the main emission source for fine particles and Nitrogen Oxides in cities, where often the legal emission threshold limits are exceeded.
A legal ban of Diesel vehicles in inner cities to reduce those emission would hit the taxi branch hard; approximately 95 % of all German taxis are equipped with a Diesel engine. Therefore; the city of Mainz is aiming at a substitution of Diesel vehicles (DV) by Hybrid Electric Vehicles (HEV) or Battery Electric Vehicles (BEV) in the taxi fleet. This raises the question whether such a substitution is economically feasible for the taxi operators (companies or single taxi owners).
Annual total cost for DV, HEV and BEV are compared under typical conditions in the Mainz taxi industry. The average mileage of taxi vehicles in Mainz is 224 km/day, of which short distance drives (<6 km) account for 70 %. Both values support an operation of BEVs in this industry.
