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. Citroen is part of the Stellantis group (formerly PSA Peugeot Citroen). The factory calibration on Citroen diesels is conservative, leaving headroom for Stage 1.
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. High-output Citroens are rare, as the core segment is low and mid.
