Motor Sport; Sports Models for 1931
Details of the Triumph range of "Super Sevens" for 1931 show that these small cars have undergone many interesting alterations. These are mainly in respect of the bodywork, the specification of the chassis remaining generally similar to that of the 1930 series. The number of types has been reduced from eleven to seven, one of these, the sports "Gnat" being an entirely new production. As in the past the engine has a capacity of 832 c.c., with a Treasury rating of 7.9 h.p. Lockheed hydraulic brakes once again figure as an important item in the specification. Magneto ignition is employed on the four-seater tourers and on the new "Gnat," but the 2-4-seater de Luxe and the three saloons are equipped with coil ignition. In the new model a standard Super Seven chassis is employed, but the engine is specially tuned. The body, which has very clean lines is of the streamlined sports pattern. The spare wheel is stored inside the tail, which also houses the detachable hood when this is not in use. Cycle type wings with full valances are fitted. The price of the "Gnat" is £185
