Cambridge

Cambridge was the automobile marque of Cambridge Engineering, the specialist business founded in 1934 by L. M. 'Bill' Williams. The name came not from Cambridge city or university but from the firm's Cambridge Road premises near Kew Green in west London. Williams built, rebodied and tuned Austin Seven road and competition specials and became a prominent source of affordable performance equipment: high-compression alloy cylinder heads, manifolds, twin-carburettor arrangements, freer exhausts, lightened flywheels, remote gearshifts, small-diameter wheels and suspension parts. The company also supplied Bowdenex independent front suspension made by Bowden Engineering; its transverse leaf-spring layout had weaknesses in fore-aft location and camber control and should not be mistaken for a separate car model. Derek Thomas and Jack Brown took leadership in 1958, when Cambridge began regular production of cars and kits under its own badge. The only complete family was an open two-seat sports special on retained Austin Seven chassis and running gear. Its aluminium panels over an ash frame evoked an MG J2 but omitted doors. A standard shell cost £27 10s in a 1958 list and a £30 lengthened version accommodated the longer 1932-on Austin chassis. These body lengths, customer donor years, engine tuning stages, kit versus completed delivery and competition preparation are configurations of one Cambridge Special family. Surviving cars are often registered and described as Austin Seven Cambridge Specials because Austin supplied the chassis identity; pre-1958 donor build years do not prove Cambridge-series manufacture before the marque launch. About 150 Cambridge cars or kits are reported overall. Cambridge Engineering acquired Speedex Castings & Accessories in 1962 and marketed remaining Speedex components and Silverstone bodies into 1963, but those retained the Speedex product identity. Bill Williams died in 1964 and Cambridge production ended in 1967. The marque is unrelated to Austin's Cambridge saloon range, Plymouth Cambridge, Cambridge University projects, Lister of Cambridge, or modern engineering firms sharing the geographic name.
