Citroen is a French carmaker, founded in 1919 by Andre Citroen. Citroen has a history of innovation, from hydropneumatic suspension to front-wheel drive. Citroen shares platforms and engines with Peugeot, Opel/Vauxhall and DS within Stellantis. The Citroen petrol range is shared with Peugeot and Opel within Stellantis. Low-output Citroen petrol engines are naturally aspirated city units, so the gain is modest. PureTech is Citroen's badge for its turbo petrol engines.

The Citroen community in France and Western Europe has a large pool of Stage files. ECUs are standardised across Stellantis, so Citroen files often work on Peugeot/Opel/DS. Low-output Citroen engines are city units, and Stage 1 is safe. On naturally aspirated Citroen engines, the main effect is on throttle response.
