Guy Motors was a Wolverhampton-based vehicle manufacturer that produced cars, lorries, buses and trolleybuses. The company was founded by Sydney S. Guy (1885-1971) who was born in Kings Heath, Birmingham. Guy Motors operated out of its Fallings Park factory from 1914 to 1982, playing an important role in the development of the British motor industry.
Sydney S. Guy registered Guy Motors Limited on Saturday 30 May 1914, the same day he departed his position as Works Manager at the Wolverhampton company, Sunbeam. A factory was built on the site at Fallings Park, Wolverhampton. and by September 1914 production was underway on the newly designed 30cwt lorry. This employed a much lighter form of pressed steel frame, unlike the more commonly used heavy rolled steel channel frames of the time. This made the vehicle able to cross difficult terrain and a 14-seat post bus built based on the design was used for crossing the Scottish Highlands.
In 1915 Guy came under control of the Ministry of Munitions and production was focused on the war effort. The factory continued to produce 30cwt lorries which were supplied to Britain's allies in the First World War. They also produced Wasp and Dragonfly radial aircraft engines, Tylor truck engines and Maudslay gearboxes as well as being the country's largest maker of depth charge fuzes. For their efforts during the war Guy received a commendation from William Weir, Secretary of State for Air. Due to orders from the ministry Guy prospered during the war, expanding its factory and became an established name in British manufacturing.
The post-war period was difficult for the motor industry as military contracts were cancelled and military vehicles no longer required for service were sold onto the market at low prices. Guy returned to the civilian market, deciding to make luxury cars with a design by RH Rose, also from Sunbeam. They produced the Guy 8-cylinder car, powered by the first British V8 engine and featuring horizontal side valves. Around 25 of these were made and it was joined by a smaller model in 1922 with the 2465 cc four-cylinder 16.9 hp. A cheaper model followed in 1924 with the 1954 cc 13/36 with an engine from Coventry Climax. About 110 of the 4-cylinder models are thought to have been made. Production also continued on vehicles based on the 30cwt chassis such as the Guy charabanc and their major success the 30 seater bus.
