EFP - Mars II

The Mars II was based on a Renault R-10 sedan, and was manufactured by the Electric Fuel Propulsion Corporation.
The Mars II operated on a 120-volt system, using tri-polar, lead-cobalt batteries (lead-acid) which could be charged to 80% capacity in 45-minutes. The D.C. motor was rated at 15 horsepower and the transmission was a manual, 4-speed. The power controller was manufactured by the Hartman Manufacturing Electrical Company and was a series/parallel switching system. Total driving range on pure battery was 146 miles on a single charge. The MARS II sold for $4,800.00. Just over 40 were built, with the majority being used by utility companies.
