Car Of The Month

1955 346 Sapphire Mk 2

1955 346

To many, the 346 Sapphire is the most remembered of all Armstrong Siddeley cars. Launched in 1952 and named after the highly successful aero engine, it was a major departure from the previous 16/18 range that had their origins from pre-war cars. The Sapphire was a large, comfortable executive saloon with an all-new 3.4 litre engine of advanced cross flow, square design with hemispherical combustion chambers in the cylinder head. The car was an immediate success with both company executives and the general public and soon became a car to aspire to. Models were available at different times with manual, electric pre-select, and fully automatic gearboxes. There were many optional extras such as power steering, electric windows and driver-controlled adjustable rear shock absorbers. This particular model also has the rare front "bucket" seats and fast lift windows. This 1955 car was found in 1986 by its current owner in a derelict condition and he then spent the next 6 years meticulously restoring it to its current magnificent condition. The car has won many concours prizes far too many to list here but most recently in 2014, the Master Class trophy and the best overall post-war car. Over recent years the car has travelled extensively throughout the UK from its Cheshire home and to events on the near continent. The "346" was one of the success stories from the Armstrong Siddeley factory with a total of nearly 7800 produced.
