Humber's large transatlantic styled saloon for the late 1950s, perhaps by some American designs they had seen, such as the 1955 Buick Special. with 6-cylinder power from a 2651cc ohv engine designed with help from Armstrong Siddeley, the Super Snipe Series I was a better equipped and more upmarket version of the Humber Hawk Series I. In 1959 Series II cars were given front discs and a 2965cc engine. The Super Snipe engines were new ohv units strongly based on an Armstrong-Siddeley engine, and in return Sunbeam Alpine sports cars were built by Armstrong Siddeley. The Series III Super Snipe had a longer nose so that it could be fitted with air conditioning and a new quad headlamp front. Jumping ahead of Hawks, a Series IV Super Snipe got a larger rear window (in common with the Series III Hawk) in 1962. The final version of the Super Snipe was the Series V with a new six-light body and changed front and rear windscreens from 1964. At the same time, in 1964, the even better equipped Humber Imperial was announced. All models ceased production in 1967.
