Wolseley 7.5 H.P. motor car, 1902-3. It has a twin-cylinder horizontal engine, transmitting power through a cone friction clutch and Renold's chain to a shaft on the change-speed gearbox, and side chains transmit the power from a countershaft on the gearbox to the rear wheels.

This car is a good example of an early British design which differed from the dominant chassis and transmission layouts of European manufacturers De Dion-Bouton and Renault. There were a variety of arrangements used by early car companies as the design of the light car took shape. However, Renault's transmission system was soon adopted as the standard and layouts like this Wolseley were dropped. This car was designed by Herbert Austin, who later left Wolseley to found the Austin Motor Company where he designed the famous Austin 7 light car.
