Citroen DS21: blue coupe

The Citroën DS is a front mid-engined, front-wheel drive executive car manufactured and marketed by Citroën from 1955 to 1975, in fastback/sedan, wagon/estate, and convertible body configurations, across three series of one generation.

The DS 21 was  introduced for model year 1965. This was a 2175 cc, five main bearing engine; power was 109 hp. This engine received a substantial increase in power with the introduction of Bosch electronic fuel injection for 1970, making the DS one of the first mass-market cars to use electronic fuel injection. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.

Lastly, 1973 saw the introduction of the 2347 cc 115 hp (86 kW; 115 hp) engine of the DS 23 in both carbureted and fuel-injected forms. The DS 23 with electronic fuel injection was the most powerful production model, producing 141 hp (105 kW).

The top of the range ID model, The DSuper5 (DP) gained the DS21 engine (the only model that this engine was retained in) for the 1973 model year and it was mated to a five-speed gearbox. This should not be confused with the 1985 cc DSuper fitted with an optional “low ratio” five-speed gearbox, or with the previous DS21M (DJ) five-speed.
