the car kept getting small upgrades each with a new designation. In September 1958 the Gazelle, now re-designated III, received better seats, enhanced at the front by a folding central arm rest. A new two-tone paint became available with this upgrade. The IIIA, introduced September 1959, gained small tail fins and a larger windscreen. The engine was upgraded with twin Solex carburettors replacing the single Solex, distinguishing it from the Minx, and lifting output to 60 bhp. 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. What is not made clear is whether this was a Gazelle IIIb or an earlier Gazelle IIIa model, fitted with the twin carburettors. 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. A 4sec saving.
