The post-war Wolseley range was launched at the 1948 Motor Show and comprised two models: the 4/50 and the 6/80. They followed the Morris Oxford and Six, sharing the unitary construction body and independent front suspension. Both the 4/50 and 6/80 had new OHC engines. Influenced by Alec Issigonis, the larger cars in the ranges resembled scaled-up Morris Minors.

Of the two Wolseley cars, the 6/80 was most popular and almost 25,000 were built before 1954. The 4/50 was discontinued in 1952 after a run of only 9,000 cars. The 6/80 partly owed its success to excellent export sales, particularly Australia. The 6/80 was also, like earlier Wolseley cars, popular with police forces.
