Classic MG

Introducing both Midget and 18/80 at the 1928 motor show was a turning point for MG. Cecil Kimber insisted on some firm orders at Olympia before committing to a big 2½litre 6-cylinder as the Edmund Road factory was made ready. A prototype 18/80 went on show with encouraging results, and the while the new car was not quite in the soon-to-be-vacated sporting territory of Bentley, it was more grown-up than most MGs. First to have the distinctive upright MG radiator shape that did so much to establish the identity of classic MGs, it was also the first 6-cylinder even though it continued using lots of Morris Motors’ components. Morris-derived engines in MGs had tended to be basic and side-valve, until the acquisition of Wolseley, along with Frank Woollard a former colleague of Kimber’s, who was made works manager. Woollard encouraged adventurous designs with an overhead camshaft, regarded by William Morris as a needless extravagance. Parsimonious Morris disapproved of the expense and the engine was never a success in Morrises. The 18/80 was treasury rated at 17.9hp but never attained anything like the 80bhp (60kW) implied in the title. About 60bhp (44.7kW) was its best ever. Advertisements claimed it had the sports performance and luxurious ease of a Two Thousand Guinea creation, “truly a competitor for the contemporary Alvis and Lagonda”. It was certainly a notable MG of the Vintage period, commendably smooth with strong torque and a surprisingly compliant ride. MG designed the chassis with 6in deep channel section side members and box-section cross-bracing, together with the axles although the torque tube transmission was pure Morris. One curiosity was the “MG” cast into the bulkhead uprights. It was neither octagonal nor could it ever be seen, except when the bodywork was entirely removed. Classic MG digital edition £7.56
