Following the end of the war, the pre-war Sunbeam 12/16 was revised and reintroduced as the Sixteen. It used a sidevalve four cylinder engine of 3016cc with a fixed cylinder head and Claudel Hobson carburettor. It had a four speed gearbox with semi-elliptic suspension (underslung at the rear) and rear wheel brakes only.
Approximately 2050 Sixteens were built.
For 1922, there was also a sports model with a 16 valve overhead camshaft engine, still of 3016cc, developing 60bhp @ 3000rpm.
