The Citroën 2CV was unveiled at the Paris Motor Show in 1948 and was originally equipped with a 375 cc boxer four-stroke engine. This engine was used in the first 2CV model, the Type A, manufactured from 1949 to 1954.
The subsequent AZ and AZU models had a displacement of 425 cubic centimeters (66 mm bore).
For the model years 1968 through 1979, the 2CV4 Type AZ A2 was offered with an engine featuring a displacement of 435 cubic centimeters (68.5 mm bore).
In 1961, the 2CV engine with a displacement of 602 cm³ was introduced alongside the 2CV AZAM. This engine is the most widely produced 2CV engine and was used until production ceased in 1990. The version with a 602 cm³ displacement underwent four further developments and, throughout its history, consistently weighed 66 kg.
By the way: In Germany, the 602 cc engine was listed as only 597 cc for tax reasons. However, the engine is identical in construction to the 602 cc engine—a nice gesture from Citroën so that customers would have to pay slightly less vehicle tax!
The 602 cc engine is installed in numerous 2CV sedan models, including the 2CV6 (Type AZ KA), the Spécial (Type AZ KB), and the limited-edition 2CV series Charleston, 007, Dolly, Cocorico, and France 3 (Type AZ KA). This engine was also installed in numerous 2CV delivery vans (Kastenente) such as the AK350 and the AKS400, as well as other related vehicles (Dyane 6, Ami 6, Méhari, Acadiane...).
The 602 cm³ engine is the most powerful engine in the 2CV series. Depending on the model, maximum power output reaches up to 33 hp.
In Germany, a slightly detuned version was installed starting in 1988, designed for unleaded regular gasoline. In this version, the 602 cm³ engine had a compression ratio of only 7.8:1. Citroën also released a special model for this engine: the legendary “I fly unleaded” 2CV.
