In October 1958, a new Super Snipe was introduced and confusingly, the designation returned to the Super Snipe I but this time the variants were identified by a series number. The new car was based on the unitized chassis and body of the four cylinder Humber Hawk, but with a 2.6 litre, enlarged in 1959 with the Series II to 3 litre, Armstrong Siddeley based, inline six cylinder engine. It also featured unitary construction and, from the time the engine was enlarged, disc brakes on the front wheels.
The Series III of 1960 was largely a styling update and can be distinguished by having four headlights and the 1962 Series IV had a slightly higher tuned engine giving 124.5 bhp (93 kW) as against 121 bhp (90 kW).
