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.
These models were built at Morris's Cowley factory alongside the 'Oxford'. They were replaced in 1953 and 1954 by the Wolseley 4/44 and 6/90.
In order to accommodate its longer six-cylinder engine, the 6/80 was longer by 7 in (180 mm) than the 4/50. It also had larger brakes with 10 in (250 mm) drums compared with the 9 in (230 mm) ones of the 4/50.
A 6/80 tested by the British magazine The Motor in 1951 had a top speed of 85.3 mph (137.3 km/h) and could accelerate from 0-60 mph (97 km/h) in 21.4 seconds. A fuel consumption of 21.8 miles per imperial gallon (13.0 L/100 km; 18.2 mpg-US) was recorded. The test car cost £767 including taxes.
A second-hand car review published in England in 1960 observed that "even the most junior member of the family" would recognise the Wolseley 6/80 as the "Cops' Car" both on television, and on the streets. The car was reckoned to offer a good power-to-weight ratio in combination with steering and suspension sufficiently excellent to permit to be "thrown around without detriment to the car and with little discomfort to the occupants".
