The Wolseley 4/50 and similar 6/80 were Wolseley Motor Company's first post-war automobiles. They were rushed into production in 1948 and were based on the Morris Oxford MO and the Morris Six MS respectively. The 4 cylinder 4/50 used a 1476 cc 50 hp version of the 6/80 engine, while the 6/80 used a 2215 cc 72 hp (54 kW) straight-6 single overhead cam. The cars were well equipped and looked impressive, with a round Morris rear end and upright Wolseley grille and were used extensively by the Police at the time - the 6/80 particularly.
