Lanchester Type 1518 - 1932 5905514590.jpg

The Lanchester Eighteen at first known as the 15/18 was announced at the beginning of October 1931. Quite unlike any previous Lanchester it was their first new car following BSA's takeover of The Lanchester Motor Company Limited in January 1931. A medium sized car was a new departure for Lanchester.

The intention was to extend the BSA group's range of cars into a new price level by offering a car of moderate size and price providing economies by virtue of design and workmanship. This was the first medium sized car to be offered with the Daimler fluid flywheel and Wilson half-automatically changing gearbox which was separately mounted.

George Lanchester played a considerable part in development of this car in collaboration with L H Pomeroy. Their original concept had been a fairly small car but one still redolent of Lanchester luxury selling for about £850. In the end the standard saloon was priced at £565.


The clutch used to engage top gear gave considerable trouble in early production cars and twice had to be replaced with redesigned versions. The (then) advanced pushrod overhead valve gear proved a success and was used in later Daimlers beginning with the Fifteen which was given a similar engine.

Further detail

A redesigned engine of 2390 cc was announced on 21 September 1934 for the Olympia Show

Changes for the Eighteen:

On Autocar road test published in April 1932 the testers obtained a properly timed maximum speed of 71.43 mph.

Said The Times' motoring correspondent—The four/five seater standard saloon has three armrests in the back seat and the front adjustable bucket seats have recesses in their backs for additional toe room for rear passengers. The four doors open wide down to the running boards and the glasses in them can be wound down fully in front (the driver's has a quick-action handle) and three-quarters of the way in the rear doors. The rear-most quarter-lights are fixed. A cupboard with a door is provided either side of the grouped instruments and there is a flap pocket in each rear door. Traps are fitted in the back floorboard for access to the tools, the battery and the oil tank of the hydraulic braking system. The spare wheel and tyre are in the well on the off-side front wing. The windscreen opens fully and the wipers are electrically operated. Safety glass is provided throughout. The coachwork sits low being built outside and below the top of the frame and attached by metal holders with rubber.

An increase of engine size from 2390 cc to 2565 cc was announced on 14 August 1935.

The new frontal design used on the group's other cars has been employed on the Eighteen. As an alternative to independent front suspension the front beam axle is now controlled by parallel links.

The wheelbase has been reduced 1 inch to 9'6" = 114 in (2,896 mm) and the track increased 4 inches to 4'8" = 56 in (1,422 mm).

The manufacturer now estimates the fuel consumption to be 18 mpg

While the engine and chassis were only altered in detail completely new coachwork was announced in August 1937. It included a luggage boot at the back and the door or lid forms a baggage platform. The seating and upholstery were redesigned.
