For other uses, see Pieper (disambiguation).
Pieper was a carmaker in Belgium.
In 1900, Henri Pieper of Germany introduced a hybrid vehicle with an electric motor/generator, batteries, and a small gasoline engine. It used the electric motor to charge its batteries at cruise speed and used both motors to accelerate or climb a hill. The Pieper factory was taken over by Imperia, after Pieper died.
Auto-Mixte, also of Belgium, built vehicles from 1906 to 1912 under the Pieper patents.
