The first hybrid car was in part the brainchild of a Viennese coach builder named Jacob Lohner, who felt that gas-driven cars were too noisy and smelly. To find a solution to this problem, Lohner turned to a young Austrian engineer named Ferdinand Porsche. In 1896, when he was just 21 years old, Porsche had invented the electric wheel-hub motor, a battery-operated motor that actually fit inside the hub of a wheel. Lohner asked Porsche to combine his in-wheel motors with one of Lohner's coaches. The result was the Lohner-Porsche Elektromobil. This vehicle was first shown to the general public at the Paris Exposition of 1900.
