1895 The origins of the company as an automobile brand was in about 1895-96 when 30 year old Herbert Austin, then employed as a works manager at the Wolseley Sheep Shearing Machine Co, became interested in engines and automobiles. During the winter of 1895-96 he made his own version of a design by Leon Bollee that he had seen in Paris. Later he found that another British group had bought the rights so Austin had to come up with a design of his own.
1897 The second Wolseley car, the Wolseley Autocar No. 1 was revealed. It was a three wheeled design (one front, two rear) featuring independent rear suspension, 2-hp flat-twin mid-engine and back to back seating for two adults. It was not successful and although advertised for sale, none were sold.

1901 The first Wolseley cars sold to the public were based on the "Voiturette", but production did not get under way until 1901, by which time the company had changed hands. In that year the automobile division was spun off (with financing from Vickers) as an independent concern in Adderley Park, Birmingham. Herbert Austin managed the new Wolseley company for a short time before resigning to form his own concern, the Austin Motor Co, in 1905.

Post WWII: Morris and Wolseley production was consolidated at Cowley, and badge engineering took hold. The first post-war Wolseleys, the similar 4/50 and 6/80 models, were based on the Morris Oxford MO. Later, Wolseleys shared with MG and Riley common bodies and chassis, namely the 4/44 and 6/90, which were closely related to the MG Magnette ZA/ZB and the Riley Pathfinder respectively. Other badge engineering exploits followed at BMC.
1957 The Wolseley 1500 was based on the planned successor to the Morris Minor. The next year, the Wolseley 15/60 debuted the new mid-sized BMC saloon design penned by Pinin Farina. It was followed by similar vehicles from five marques within the year.
The Wolseley Hornet was based on the Austin and Morris Mini with a booted body style which was shared with Riley as the Elf. Finally, a version of the Austin 1800 was launched in 1967 as the Wolseley 18/85.
