AMC conversions
During the years 1970–1976, EFP produced eight vehicles based on five American Motors cars: the EFP Hornet (2) Electrosport (1), X-144 (3), Santa Fe (1) and the EFP Hatchback (1). All were equipped with the tri-polar lead-cobalt battery and had top speeds ranging from 60 to 85 mph, and could travel from 40 to 101 miles on a single charge, according to company literature.
The EFP Hornet was powered by 1,500 pounds of tri-polar lead cobalt batteries and had a range of 70 miles in stop and go traffic with a top speed of 65 mph. The electric car could be charged at home or at special fast-charge stations.[16] It operated on 144 volts and used a 20 hp electric motor. According to an article in the Duquesne Power and Light publication printed earlier in 1970, the car had a top speed of 85 mph and a range of 70 to 150 miles. No independent test results have been found. EFP planned to drop the Hornet in favor of the AMC Matador due to space problems and the ability to increase the size of the battery pack.[17]
Only one Electrosport was produced. In 1971, EFP claimed a top speed of 79 mph and a range of 101 miles at 30 mph. Abercrombie & Fitch unveiled the Electrosport, an AMC Hornet station wagon, on January 28, 1972, at their new Royal Poinciana Plaza shop in Palm Beach, Florida. Palm Beach was chosen for a test market due to its flat terrain, mild climate and isolation from metropolitan areas.[18]
The EFP X-144 was named for its 144-volt battery pack. A total of 3 X-144's were produced in 1972 and '73. Top speed was reported by EFP to be 70 mph with a driving range of 70 miles at 50 mph. The X-144 was an AMC Gremlin, beefed up with Ambassador suspension and brakes and was available with either a manual or automatic transmission. It was equipped with a slow charger on board that would fully charge the batteries overnight. The vehicle was reported to have a much smoother acceleration.[19]
The Santa Fe was based on an AMC Matador. Only one of these were produced in 1974. These were to be used in an Avis Rent a Car pilot project in Chicago. According to Avis, one charge will last for 8 to 12 hours of city driving at speeds up to 60 mph.[20] EFP testing resulted in a top speed of 70 mph and a cruising range of 60 miles at 50 mph.
One EFP Hatchback was produced in 1976. This electric car was based on an AMC Hornet hatchback. EFP reported a top speed of 60 mph and a range of 40 miles at 50 mph.
The availability of AMC vehicles came to an end and EFP soon entered into talks with General Motors.
