AEC 6-wheel RENOWN 664
Making its appearance in 1930, the 664 model was a 6-wheel chassis suitable for carrying either single-deck or double-deck bodywork.
Given a wheelbase of 18ft 7in, it was powered by an AEC 7.4 litre 6-cylinder petrol engine. Transmission was via a single plate clutch and 4-speed sliding mesh gearbox to underslung worm rear axles, whilst the brakes were either of the hydraulic or vacuum servo type, both being offered as alternatives.
In 1931 an AEC 8.8 litre oil engine was offered as an option against the petrol unit, and in 1934, a 7.7 litre oil engine was also made available. A further option was offered in 1932 in the form of fluid flywheel and 4-speed pre-selector gearbox. Production of the 664 and diesel oil engined 0664 models continued until 1940.
