Herbert Austin's third Wolseley design and his first four-wheeler, forming the basis of production models that Wolseley introduced in 1901. It has a front-mounted engine with a single horizontal cylinder and a belt drive to a central gearbox and chain drive to the rear wheels. Steering is by a tiller.

Austin drove this prototype in the 1900 Thousand Miles Trial and was awarded first prize in his class. The Wolseley was one of the exhibits in Britain's first motor museum which opened in 1912. The museum was the brainchild of Edmund Dangerfield, proprietor of The Motor magazine and hence was known as The Motor Museum. It was located in London, at Waring and Gillow's furniture store on Oxford Street.
