1959 Ford Prefect converted to electric power

Made 1959

This is a 1959 Ford Prefect Model 100E made by the Ford Motor Co. of Australia at Geelong in Victoria. It is unusual because the car was converted to run on electricity by Roy Doring, said to be Sydney’s first auto electrician, a business he established in Rockdale in 1921. The car was claimed to have been Australia’s first post-World War II electric-powered sedan and the last of 51 vehicles Roy converted to electric power. Roy drove electric cars for years and used this car as his own vehicle. ...

This is a four-door sedan with black livery, the body is made of pressed steel panels and the chassis is spot welded and brazed together. The side of the car has the lettering: "Doring Bros 36 Hattersley St Arncliffe Auto Electrical Specialists".

Inside, the trim and upholstery are in maroon coloured leatherette with white piping. The car has two bucket seats in the front and a bench seat in the rear. The head lining is white and there are rubber floor coverings. The front floor wells have added carpet car mats and a piece of offcut carpet.

The dashboard has been modified and to the right of the steering wheel two instruments had been added for electric operation. These comprise a large industrial type electrical knife switch with an orange handle, which is inscribed "60 Amp Turnbull 125 volts", to connect and disconnect the power, and a voltmeter in the form of a dial. A switch for selecting forward and reverse gears has also been added.

There are metallic stickers for Exide batteries on the rear right side window and the rear windscreen, a 1954 Royal Tour badge attached to the radiator grill and a NSW Registration label dated June 1981. The number 51 added near the right tail light refers to this car being the 51st converted by Roy Doring to electric power.

This Model 100E Ford Prefect was assembled at the Ford plant in Geelong, Victoria. A total of 100,554 Ford Prefects were made between 1953 and 1959 assembled in England, Australia and New Zealand. The car was originally fitted with a 1172 cc Ford straight 4-cylinder petrol engine and a three-speed grearbox.

Roy Doring converted this Ford Prefect into electric operation by removing and selling the petrol engine and in its place putting an early electric car engine under the bonnet. This 3 kW electric motor was coupled directly to the original three-speed gearbox through a flexible joint. The electric motor spun at 2,500 rpm and could draw up to 220 amps during acceleration. Once the car reached a steady speed the amperage dropped to around 50. Electric power for the motor was stored in 13 batteries divided amongst the boot and under the bonnet to balance the car's weight.

To drive the car was very simple. It had no clutch to push nor gears to change. The original Ford Prefect gearbox was retained to provide reverse gear. The accelerator pedal was used to drive the car forward and the normal brake to stop. When the car was parked the batteries were disconnected with a large master switch near the steering wheel.
