The BSA Light Six was a small car in the twelve tax horsepower class manufactured for BSA Cars by BSA subsidiary The Daimler Motor Company Limited. Announced in September 1934 it was a cheaper and less well-finished version of the Lanchester Light Six
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.
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).
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.
The Light Six was available in two body styles, one being the Six-light saloon and fixed head coupé which cost £315 and the other being the streamlined saloon and sports saloon which cost £325.
