Externally the only significant difference was a restyled nose based around a traditional Singer grille.

[4] The body style followed by the Gazelle between 1956 and 1967 came to be known as the "Audax" body, with significant input from the US based Loewy design organisation, highly regarded at the time partly on account of Loewy's input to several iconic Studebaker designs.

[5] The Gazelle Series II, offered from autumn 1957, was also available as an estate car, and had optional overdrive and larger fuel tank.

To compensate for the loss of body rigidity by the removal of the roof, extra cross bracing was fitted under the car.

In September 1958 the Gazelle, now re-designated III,[5] received better seats, enhanced at the front by a folding central arm rest.

[9] The IIIA, introduced September 1959,[5] gained small tail fins and a larger windscreen.

Home market cars got a floor gear change and as well as overdrive, Smith's Easidrive automatic transmission also became an option.

Autocar Magazine carried out a Used Car Test, No.214 in their famous series, on a Singer Gazelle III first registered on 2 January 1961.

In comparison with the new Gazelle IIIb tested on 17 March 1961, it reached 0-60 mph in 23.9secs,compared with the used car at only 19.9secs.

The IIIB, launched September 1960,[5] reverted to a single carburettor which improved fuel consumption and facilitated servicing "in remoter territories".

The IIIC, launched July 1961, was fitted with a larger engine of 1592 cc developing 53 bhp.

[7] In July 1961 the Rootes Group released the new Singer Vogue, using the body of what was intended to be the Gazelle IV.
