Work on the first Lanchester car had been started in 1895, significantly designed from first principles as a car, not a horseless carriage, and it ran on the public roads in February or March 1896. It had a single-cylinder 1306 cc engine with the piston having two connecting rods to separate crankshafts and flywheels rotating in opposite directions giving very smooth running. A two-cylinder engine was fitted to the same chassis in 1897 and a second complete car was built alongside it. This led on to the first production cars in 1900, when six were made as demonstrators. These had two-cylinder, 4033 cc, horizontal air-cooled engines, retaining the twin crankshaft design. Steering was by side lever (or tiller) not wheel. The gearbox used epicyclic gearing. The first cars were sold to the public in 1901. In 1902 Lanchester became the first company to market disc brakes to the public. They were mechanical and on the front wheels only. The discs were very thin and made of a very soft metal like brass. Although probably leaving much to be desired, they completely fit the definition of a disc brake, and beat all others to market by many years.
