Background

A more recent working prototype of the HEV was built by Victor Wouk and earned him the title as the “Godfather of the Hybrid”. Wouk installed a prototype hybrid drivetrain into a 1972 Buick Skylark provided by GM. In 1989, Audi produced its first iteration of the Audi Duo (or Audi 100 Avant duo) experimental vehicle, a plug-in parallel hybrid based on the Audi 100 Avant Quattro. This car had a 12.6 BHPSiemenselectric motor which drove the rear wheels.
