The Lanchester Fourteen Roadrider is a six-cylinder automobile introduced by the Lanchester Motor Company in the beginning of September 1936. It was named "Roadrider" for its special suspension features, and billed as the lowest-priced six-cylinder Lanchester ever offered. This car replaced the previous 12 hp (tax horsepower) Light Six model with a larger six-cylinder (14 hp tax horsepower) engine again in the Lanchester Eleven chassis and body.
The four-light four-door sports saloon was given a new "razor edge" body. The entirely new Roadrider shape, introduced within twelve months, was similar in appearance.
The Fourteen was continued after World War II, with a coachbuilt body for the home market and, under the Lanchester Leda name for the export market, with a lighter all-steel body.
These followed the customary Lanchester practice and the transmission included the Daimler fluid flywheel and the self-changing pre-selective four-speed gearbox. Final drive was by underslung worm gear.
Magna type wire wheels and fully chromium-plated bumpers were standard. There was a new range of coachwork. Upholstery was provided in a new style either in all leather or a combination of leather and cloth. The windscreen had remote-motor dual wipers operating from the bottom.
A new Lanchester Roadrider "breaking fresh and important ground" was announced at the beginning of October 1937. Engine, chassis, and body were all different, and larger and independent front suspension was now provided. An optional manual syncromesh gearbox with an ordinary clutch was also available at reduced price. This car was a simpler, less luxurious version of the Daimler New Fifteen, sharing the two standard bodies but using a smaller engine.
details in addition to tabled data
The crankshaft ran in four bearings The engine unit had bi-axial four-point rubber mountings.
"On the offside are the horizontal carburettor, the manifolds held by brass nuts, the air-cooled dynamo with a belt drive common to the combined fan and impeller and the steering box which has worm and double roller gear.
On the nearside the vertically driven make-and-break and distributor is placed centrally and has a neat easily detachable cover over the top which also hides the sparking plugs and wiring. Here also are the water tap, the coil, pressure oil filter, dip rod, sump drain plug, starter and mechanical fuel pump"
Power was transmitted to the rear wheels with the usual Daimler fluid flywheel and self-changing gearbox but the final drive was now by spiral bevel. A pin roller-bearing propeller-shaft led to a half-floating spiral bevel driven back axle.
Independent front wheel springing was provided in the form of parallel links with coil springs, radius arms and torsion bar damping. The rear half-elliptical springs also were given a torsion bar stabilizer and hydraulic shock absorbers. They were rubber-mounted to minimise vibration. The exhaust system was also insulated.
Wheelbase and track had been extended by 7½ inches and 4 inches respectively, providing more body space and inter-axle seating. Steering was now by worm and double roller.
Tyres 5.75 x 16 inches.
Bendix mechanical brakes were on all four wheels.
The radiator case was carried well forward of the front axle which lengthened the bonnet and, with the sweeping lines of the body, gave a big car appearance. "Easy clean" wheels were fitted, the front seats were adjustable, and the steering wheel column was telescopic.
A luggage boot was added at the back with a separate lockable compartment for a spare wheel. Other additions were footrests for the back passengers, an electric cigarette lighter, a sunshine roof, double screen wipers, sun visors, and a new pistol-grip handbrake lever on the dash.
Lanchester estimated the fuel consumption to be 22 mpg. Maximum speed 70 mph.
either car might be had with four-speed syncromesh gearbox and friction clutch for £350
