The Alvis 14.75 is a car manufactured by the British car manufacturer Alvis from 1927 to 1929. It was the first Alvis with a six-cylinder engine.
The car has a straight-six engine with overhead valves, fed by a single Solex carburettor. Its bore and stroke are 63 mm × 100 mm, giving a displacement of 1,870 cc . The front and rear axles were supported by semi-elliptical longitudinal leaf springs.
The 14.75 was offered with two different wheelbases: 2,845 mm for two-seater versions, and 3,010 mm for four-seaters. Three body types were offered: saloon, convertible and roadster. In 1930, after selling some 492 examples, the 14.75 was replaced by the Alvis Silver Eagle.
