The 20 was a car made by Sunbeam that was made between 1926 and 1930. Over 2000 were built during this time.

The 20 was fitted with a 2916cc six cylinder engine. It had overhead camshafts and pushrods. The engine was connected to a four speed gearbox via a single plate clutch. The engine produced 55bhp and the top speed of the car was 65mph (105kmh).

The chassis was 10ft 4in and had semi-elliptical leaf springs on the front with cantilever suspension on the rear. On the final cars, semi-elliptical leaf springs were fitted on the rear of the car as well.

The car was fitted with rod-cable operated brakes and in 1929 servo controlled brakes on the rear wheels with separate shoes were added.

The Light four-seater cost £750 when new.
