At the 1954 Salon de L'Automobile de Paris, Talbot-Lago presented their last new engine: the new four-cylinder still had the typical twin laterally mounted camshafts, although it was upgraded to five main bearings. The new 2,491 cc engine was called the T14 LS, but it did not have a car to go in until May 1955 when the Talbot-Lago 2500 Coupé T14 LS was finally presented. The first car had all-aluminium bodywork, but later cars used more steel. Fifty-four of these coupés were built, but they proved hard to sell - the stylish bodywork couldn't quite hide the thirties' underpinnings, and the rough engine offered little elasticity nor longevity.
