AEC REGAL 4

The Regal 4 (not to be confused with the Regal IV of later postwar years) went into production in 1930 as AEC's 642 model. Being basically the same chassis as the Regal 662 model, the Regal 4 had a wheelbase of 17ft 6in. It was originally powered by an AEC 4-cylinder petrol engine of 5.123 litres capacity, with 4-speed crash gearbox and semi-floating rear axle. In 1933 it was fitted with a fully floating rear axle and Inckheed hydraulic brakes. At the same time, an alternative engine
was offered, this being an AEC 4-cylinder oil unit of 6.7 litres capacity chassis fitted with this being classified 0642.

Never proving to be an over popular model, only 180 Regal 4s had been built when production came to an end in 1937, although the model remained available until 1940.
