The 1½ Litre Le Mans is a car produced by Singer between 1933 and 1936. 71 cars were built.

The 1½ Litre Le Mans had a 1493cc six cylinder engine. It had a single overhead camshaft and had twin Solex carburettors. A high-lift camshaft was fitted and ignition was by a coil. The engine was connected to a four-speed constant-mesh gearbox via a single-plate clutch. The engine produced 48bhp and accelerated the car up to 75mph (121kmh).

The chassis was 7ft 8in long and provided enough room for the large engine and four seats. The chassis had semi-elliptical leaf springs all round and Lockeed hydraulic brakes on all four wheels.

Singer built four works cars and were largely unsuccessful. Three of them were sold of to private owners and the cars were converted where they were used in trials and earned many successes.

Vanden Plas gave the coachwork style by giving the car the swept front wings and a spare wheel on the tail.

The 1½ Litre Le Mans cost £295 when new.
