The Armstrong Siddeley Sapphire is a large automobile which was produced by the British company, Armstrong Siddeley Motors Limited, from 1952 to 1960.

A distinctive element of the Sapphires was the traditional Armstrong Siddeley V-shaped radiator grille with the Sphinx motif mounted on it.

On some models the sphinx sported aircraft wings carrying tiny Armstrong Siddeley Sapphire jet engines.

Chronology
Predecessor Whitley

The 236 was made between 1955 and 1957 and used the six-cylinder 2,310 cc engine previously seen in the Armstrong Siddeley Whitley. A conventional manual gearbox was available but many were fitted with a Lockheed Manumatic "clutchless" transmission. Overdrive was an option on either transmission.

This car with an 85 mph maximum was intended to be a quiet, flexible, easy-to-drive saloon.

603 were produced.
