It was described by the motoring correspondent of The Times as not intended to be a replacement for the Ten but as an alternative model perhaps for the more fastidious[1]

Engine

The new engine design was on the same general lines as the Lanchester Eighteen (not 15/18) though with a chain-driven dynamo and a much reduced bore and stroke taking down the swept volume from 2,390 cubic centimetres (146 cu in) to 1,378 cubic centimetres (84 cu in)

Chassis

The larger twelve horsepower six-cylinder engine was mounted in the chassis of the ten horsepower four-cylinder BSA Ten. Steering was by cam and lever, brakes were mechanical. Tyres specified were 5 inch on 18 inch wheels.
