Auto-Mixte built cars between 1906 and 1912 using a hybrid-technology under license from Pieper, it introduced a 3-1/2 horsepower "voiturette" in which the small gasoline engine was mated to an electric motor under the seat. When the car was "cruising," its electric motor was in effect a generator, recharging the batteries. But when the car was climbing a grade, the electric motor, mounted coaxially with the gas engine, gave it a boost. most were commercial transport.
From 1910 they used a Knight sleeve valve engine.
From 1912 to 1914 the cars were made as Pescatore, named after the owner.
The outbreak of World War I marked the end of the car. The workshop was eventually taken over by a motorcycle manufacturer Gillet Herstal. Auto-Mixte made buses for the City of London as well; one electric engine driving each wheel, therefore creating one single walkway without obstructions.
