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 Lanchester Ten. Steering was by cam and lever, brakes were mechanical. Tyres specified were 5 inch on 18 inch wheels.

The most popular bodywork styles were the saloons. These were available as both 'six light' and 'four light' versions, the term 'light' here referring to the side windows. The six-light had a longer roofline with a third side window behind the rear door, the four-light sports saloon had a fixed head canvas body above the waistline.
