The Talbot Lago Baby (1948–1951) marked the return of a pre-war Talbot model name and was the third model presented by the company during the 1940s. The car was commonly sold as a four-door sedan, but a two-door cabriolet was also offered. Its engine comprised only four cylinders, but the twin overhead camshaft with cylinder valves on both sides of the engine block was again featured: at 2690 cc the engine capacity equated to a fiscal horsepower of 15 CV which was enough to attract the punitive levels of car tax applied by the French government to large cars. The power output was initially 110 bhp (82 kW), which in 1949 was increased to 120 bhp (89 kW). Although the postwar Baby sedan closely resembled the more powerful Record on a brief glance, the Baby's 2,950 mm wheelbase was slightly shorter than the 3130 mm wheelbase of the Record, and the overall length was correspondingly 200 mm shorter, reflecting the shortened 4-cylinder engine block. Additionally the cheaper car sat on a simplified suspension set-up. Baby customers could specify as an option a Wilson pre-selector gear box.

Talbot Lago manufactured three special made seven-seater presidential cars one for the President of France, one for the President of Tunisia and one for the Royal family in Saudi.
