 First unveiled in Vienna, Austria, on 26 June 1898, Porsche had engraved the code "P1" (standing for Porsche, number one, signifying Ferdinand Porsche's first design) onto all the key components.The Egger-Lohner was a carriage-like car driven by two electric motors within the front wheel hubs, powered by batteries.This drive train construction was easily expanded to four-wheel drive, by mounting two more electric motors to the rear wheels, and a four-motor example was ordered by Englishman E. W. Hart in 1900.
