The Humber 16/20 was one of the models manufactured by Humber Limited and was introduced in 1909. This rear wheel drive car was available as tourer (open convertible), closed sedan and landaulet. It was powered by a 3.0L inline four engine and a 4-speed manual transmission. The 16/20 was considered a reliable and relatively luxurious car in its time, performing well by pre-World War I standards.
This model was sometimes used as an official vehicle or for public services, such as taxis and executive transportation. The Humber 16/20 was produced up to 1915.
