20.9 hp Tourer
The Sunbeam 20, introduced for 1927, featured a 2916cc overhead valve six cylinder engine with a rating of 20.9 hp and a four speed gearbox. It used semi-elliptic front suspension and cantilever rear suspension. The four wheel brakes were operated by cable at the front and rod at the rear. A Claudel Hobson carburettor was fitted.
Body styles available were: 2-seater, tourer, fixed-head coupe, folding-head coupe, coachbuilt saloon, Weymann saloon and Rally Weymann saloon.
A long wheelbase chassis was introduced in 1928 for the carriage trade.
Production of the 1926-30 type ran to around 2560 units.
In 1930, the 20 was revised with a new 3317cc OHV six (rating 23.8 hp), Zenith carburettor and a slightly larger chassis. Other revisions included vacuum servo brakes and a silent third gearbox. Around 752 of the 1931-33 type were built.
