In 1928 MG moved away from it’s original remit of giving Morris Bullnose products wider appeal which culminated in the MG 14/40 and started to manufacture it’s own chassis and engine blocks.
The new 18/80 model featured both a unique MG chassis and engine block both of which had been developed from lessons learned from a Morris Light Six Saloon that never went into production. The new distinctive radiator design would be maintained all the way through to the T Series.
The 18/80 also featured unique to MG front and rear axles with Rudge Whitworth centre lock wheels an either tourer or saloon body styles.
The twin carburetor six cylinder motor featured a four bearing crankshaft with a Duplex chain, see behind the radiator on the right, which drives the camshaft, distributor, water pump, oil pump and dynamo. The MG 80 hp rated six gave the 18/80 enough power to reach 100 mph. The motor seen here has been upgraded with a MK III cylinder head and ignition and drives through a Rover SD1 clutch in place of the original cork in oil unit.
The 1929 chassis of the vehicle featured today was originally built as a prototype for the MK II saloon in 1929 however by the early 80’s the body was in such a poor state that it was replaced with a Mk III 18/100 ‘Tigress’ style body. Note the unique silver plated steering wheel boss from the original Mk II Prototype has been retained, but the dash and instrumentation are from a Mk III Tigress.
As a result of underwhelming track performance, only five ready to race Mk III ‘Tigress’ vehicles, styled after the contemporary Bentley competion models, were built in period.
