The Humber Super Snipe is a car which was produced from 1938 to 1967 by British-based Humber Limited.
The Super Snipe was introduced in October 1938, derived by combining the four-litre inline six-cylinder engine from the larger Humber Pullman with the chassis and body of the Humber Snipe, normally powered by a three-litre engine. The result was a car of enhanced performance and a top speed of 79 mph (127 km/h) —fast for its day. Its design was contributed to by American engine genius Delmar "Barney" Roos who left a successful career at Studebaker to join Rootes in 1936.:p247
The Super Snipe was marketed to upper-middle-class managers, professional people and government officials. It was relatively low-priced for its large size and performance, and was similar to American cars in appearance and concept, and in providing value for money.
Within a year of introduction, World War II broke out in Europe but the car continued in production as a British military staff car, the Car, 4-seater, 4x2, while the same chassis was used for an armoured reconnaissance vehicle, the Humber Light Reconnaissance Car.
In 1946, post-war civilian production resumed and the Super Snipe evolved though several versions, each designated by a Mark number, each generally larger, more powerful, and more modern, until production ended in 1957 with the Mark IVB version.
The Mark I was essentially a 6-cylinder version of the 1945 Humber Hawk, itself a facelifted pre-war car. A version of the 1930s Snipe remained available, with the 1936-introduced 2731 cc engine. However, the standard Super Snipe engine was the 4086cc side-valve engine that had appeared in the Humber Pullman nearly a decade earlier, in 1936, and which would continue to power post-war Super Snipes until 1952. Throughout the years 1936–1952 the maximum power output of the engine was always given by the manufacturer as 100 bhp at 3400 rpm.
The Mark II announced in mid-September 1948 was mostly redesigned in chassis and body. Now a full six-seater with a bench-type front seat it was given a wider track and a variable ratio steering unit. The gear lever was now mounted on the steering column. Like Humber's Pullman the headlights were fitted into the wings and running-boards were re-introduced. The transverse-spring independent suspension, first introduced on the Snipe and Pullman in 1935, continued but with 14 leaves instead of eight.
The smaller-engined Snipe was discontinued. Early Mark II Super Snipes can be distinguished by round lamps below the head lamps. The left one was a fog lamp, and the right one was a "pass" lamp with a low narrow beam for passing cars when using dipped headlights. These were dropped in 1949 in favour of rectangular side lamps which were continued in the Mark III.
The Times motoring correspondent tested the new car at the end of 1948. The spare wheel was criticized as being difficult to extract and the indirect gears were, he thought, not as quiet as they might be. Overall the finish reflected the excellent taste that distinguished Rootes Group products
125 drophead coupés were made by Tickford in 1949 and 1950.
The Mk III followed in August 1950. Easily identifiable by spats over the rear wheels it had a Panhard rod added to the rear suspension which limited sideways movement of the rear wheels and so permitted the use of softer springs. The 1950 car can be readily distinguished from the previous model by the simpler dome-shaped bumpers and the rectangular stainless-steel foot-treads on the running-boards.
A Mk III tested by The Motor magazine in 1951 had a top speed of 81.6 mph (131.3 km/h) and could accelerate from 0-60 mph (97 km/h) in 19.1 seconds. A fuel consumption of 17.7 miles per imperial gallon (16.0 L/100 km; 14.7 mpg‑US) was recorded. The test car cost £1,471 including taxes.
The all-new Mark IV Super Snipe announced mid-October 1952, Earls Court Motor Show time, used a Hawk Mk IV body shell lengthened by 6 in (152 mm) but with a 4138 cc 113 bhp (84 kW) overhead-valve engine also used in a Rootes Group Commer truck. Chassis and suspension components were uprated to take the greater weight and power of the Super Snipe, those parts ceasing to be interchangeable with those of the Hawk. From 1955, overdrive was available as an option, followed in 1956 by an automatic gearbox.
Shortly after the car's announcement Leslie Johnson, Stirling Moss, and two Rootes Group staff, drove a new silver-grey Super Snipe from Oslo to Lisbon, travelling through fifteen European countries in 3 days, 17 hours and 59 minutes. The run demonstrated the car's high-speed reliability in far from ideal conditions.
In 1953 The Motor tested a Mk IV and found the larger engine had increased performance with the top speed now 91 mph (146 km/h) and acceleration from 0-60 mph (97 km/h) in 14.7 seconds. Fuel consumption had increased to 15.5 miles per imperial gallon (18.2 L/100 km; 12.9 mpg‑US). The test car cost slightly more at £1,481, including taxes.
The Automatic Mk IV saloon tested by The Motor in 1956 Ref. 21/56 Continental, recorded a maximum speed of 97.0mph (mean) and 98.9mph (best). 0–60 mph acceleration was 14.8 sec, with a 0–90 in 38.2 sec, The Standing Quarter Mile was 20.4 sec. The axle ratio was 3.7:1 and maximum bhp 122 on a 7.13:1 compression ratio, as stated in the data panel of this road test.
In 1957 The Times commented that the car was handsome if somewhat dated. It attracted favourable attention from passers-by and gave its occupants a satisfying sense of solidity and respectability. The two separate front seats were described as "enormous" and it was noted their backs could be reclined to the horizontal for a passenger to sleep. The steering was described as generally imprecise, uncomfortably low-geared for parking, and in need of power assistance. The car represented "remarkably fine" value for money.
In October 1958, a new Super Snipe was introduced and first presented to the public at the opening of the Paris Salon de l'Automobile. 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 new 2.6 litre, 2,651 cc, six-cylinder overhead-valve engine based on an Armstrong Siddeley design with bore and stroke of 82.55 millimetres (3.250 in) and near-hemispherical combustion chambers producing 112 bhp at 5000 rpm.
This engine was matched to a three-speed manual transmission with optional Laycock de Normanville overdrive on second and top gears, or Borg Warner DG automatic transmission. Power steering was available as an option. Also offered was a touring limousine model with glass partition.
