Chronology
Predecessor	Hillman 14
Successor	Hillman 14 Humber 16

The Hillman 16 was a series of 16 horsepower (RAC rating) medium priced 5-seater executive cars made by Hillman during the 1930s by installing a smaller engine in their 20 horsepower Hillman 20 range.

They were replaced by Hillman's 14 which changed its name between 1939 and 1945 to Humber Hawk.

Hillman made a pair of larger 6 cylinder side-valve saloon cars with two sizes of otherwise identical engines in identical bodies for the same price: this 16 horsepower car and a 20 horsepower version Hillman advertised the cars as having "Cushioned Power" mounts which helped stop vibration through the engine and gearbox and described their cars as being “built with a margin throughout”. These two models drew on some of the features and engine designs of the luxury Humber cars, including the Humber 12, 16/50, Snipe and Pullman, that were also being built under Rootes brothers control. This was an attempt by Hillman Ltd to enter the low end of the executive car market

The Hillman 16 had a 2110 cc 15.90 hp side valve straight-six engine whilst the matching 20/70 had larger 2810 cc 20.9 hp engines. The "16hp" and “20/70” saloons were five seaters with bucket seats at the front and a folding armrest dividing a bench seat at the rear. All these vehicles had Bendix "Duo Servo" brakes, which used rod and cable linkages and operated on all four wheels via both the foot pedal and the handbrake lever.

A new streamlined body was announced in October 1935 and the engine was enlarged 22 per cent by lengthening its stroke by 14 mm. Although the cubic capacity was raised from 2110 cc to 2576 cc this did not affect the car's tax rating because the RAC formula takes no account of an engine's stroke.

About (citation required) Hillman 16s were built whereas around 4100 Hillman 20/70s and Hawks were built during the same period.

Only a few examples of each model still exist in the UK today. Some of these vehicles were exported throughout the world, including Argentina, Australia, Greece and New Zealand where a number of "20/70"'s also still survive.
