Covering all the motor bus and trolleybus products of Guy Motors, this book recounts the history of an iconic British coachbuilder. It begins with the early origins of Sydney Guy's eponymous company, followed by the ubiquitous Arab bus and the eventual absorption of the company into the British Leyland empire. Starting with the small single deck vehicles of the 1920s, the story continues with the development of the six-wheeled chassis, with both internal combustion and electrically powered trolleybus formats. The book also examines the leading technological developments in braking, suspension and chassis design, now commonplace, that were to lead to both the Victory and Wulfrunian products, neither of which were the commercial success originally intended. The story develops with the acquisition of the Guy Motors business by Jaguar and eventual absorption into British Leyland, and ends with the final Guy Motors-inspired designs sold under the Leyland brand. In addition to new images of preserved vehicles, the book is illustrated with an extensive selection of period images of vehicles in normal service and manufacturer's sales brochures.
