The Elektrische Viktoria was an electric car built in several versions by Siemens between 1905 and 1909 in Berlin. The versions comprised a four-seat convertible (advertised and used as a hotel taxi), a minibus with a box-like structure (much like a pickup), and a van. Top speed was 30 km/h (19 mi/h). The electric motor operated at a nominal potential of 88 volts and a maximum current of 40 amperes. The maximum power was 3.520 kW (about 4.8 HP). The cruising range was 60 km with the smaller battery version and 80 km with the larger battery version. The car was built in the Berlin based factory Siemens-Schuckertwerke, a Siemens subsidiary. The total number of units built is not known, but, according to Siemens internal records, probably between 30 and 50 were produced. The price was steep by 1905 standards, at 11000 to 17500 Marks, depending on the model and battery capacity. At the time, a worker's monthly wages were in the range of 120 to 150 Marks. == Development == Regenerative braking was added during development, i.e., while braking the electric motor's operation was reversed, turning it into an electric generator charging the battery, such that the available kinetic energy could be turned into extended cruising range.
