the engine for the car was built in-house and was a twin-cylinder vertical water cooled unit, with 72mm bore and 108mm stroke, unusual in that both pistons rose and fell at the same time. drive was to the rear wheels through a 3-speed gearbox with reverse and worm-driven axle and spur differential. the rear springing was unusual in that the long semi-elliptic leaf springs were supplemented by coil springs. it was fitted with sankey detachable wheels and dunlop tyres.
