The Owen Magnetic hybrid car was manufactured between 1915 and 1922. It was a pure hybrid: the six cylinder engine drove a generator which charged the lead-acid batteries and powered the motor that drove the rear wheels: there was no mechanical connection from the engine to the drivetrain. The car featured regenerative electric braking which charged the batteries. The drivetrain and control system is described in U.S. Patent 1,207,732 [PDF], granted on 1916-12-12. The Owen Magnetic was a luxury car: the top of the line 1916 model sold for US$ 6,000, which is equivalent to around 120,000 rapidly evaporating 2022 BidenBucks.
