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. In December that year, the car was displayed at the Paris World Exhibition under the name Toujours-Contente. Even though this one-off vehicle had been commissioned for the purposes of racing and record-breaking, its of lead–acid batteries was a severe shortcoming. Though it "showed wonderful speed when it was allowed to sprint", the weight of the batteries rendered it slow to climb hills. It also suffered from limited range due to limited battery life.
