The 1½ Litre Sports is a car produced by Singer from 1933 to 1934, and then again in 1937. Only 12 were made in the 1937 production run.

Its design was based on Singer's Nine Sports, but was very similar in appearance to the Lagonda M45. The vehicle was fitted with a 1493cc overhead cam six-cylinder engine rated at 13 hp and featured four-speed transmission.

The engine had an ultra-strong forged crankshaft and fed by twin SU carburettors, a Scintilla Vertex magento and a single coil ignition.

The 1½ Litre Sports rode on a wheelbase of 9.5 ft, and used 5.25 × 18-inch tires and 13-inch Lockheed hydraulic brakes. Semi-elliptical leaf springs were fitted all round.

Standard coachwork was a two-door, four-seater sports body with a fold flat windscreen.

The 1933 and 1934 cars were sold for a price of £295, but the cost of the 1937 version was lowered to £259.
