In 1956 a new larger car, the open 2-seat Electron appeared using a 1098 cc overhead-cam Coventry Climax engine. The front suspension was independent using coil springs and drum brakes were used all round. The engine was expensive for the company to buy resulting in a high price of £1050 (complete) or £734 (kit); only around 20-30 are thought to have been made.
A reduced price version the Electron Minor followed in 1957 using the Standard SC engine, transmission and rear axle from the Standard Ten. In 1963 the car received a larger version of the SC engine from the Triumph Spitfire and front disc brakes came from the same source in 1966. A hardtop was available as an option. With various specification changes the cars went from a Mark I to a Mark VI which had a Triumph GT6 chassis.
It was the mainstay of production until 1973 with about 700 being built.
There was also a closed 2+2 version with Triumph Herald mechanicals called the Electrina but only about 20 were produced.
The cars were available fully assembled or in kit form. Production peaked at about 20 cars a month.
