C1
Citroen · on record 2005 to 2025
The Citroen C1 was Citroen's compact city hatchback developed jointly with Peugeot and Toyota, sharing most of its engineering with the Peugeot 107 and Toyota Aygo. The C1 had a distinct role in the Citroen range, giving buyers a reason to choose it beyond the badge alone. The remaining C1 population is increasingly shaped by the cars owners still find useful or distinctive enough to maintain once routine depreciation has run its course.

Licensed and SORN vehicles at each census. The filters below apply to the family population, MOT and registration figures. They do not alter the generation history above.
Licensed
SORN
Latest census observation
At the average decline recorded over the latest five years, the licensed fleet would reach zero around 2058.
Illustrative projection only; vehicle populations rarely decline linearly. Late fleets typically flatten as surviving examples enter preservation.
Inside the surviving fleet
AutoCensus parses every DVLA variant description, so the fleet can be read by fuel and specification rather than as one number.
First registrations by year
When surviving examples first joined the British fleet.
New registrations
Vehicles first registered each year. A fleet still being sold shows here; a finished one shows only imports.

Where the C1 remains
Based on MOT test locations, 2025. Test location is a proxy: a vehicle is counted where it was last tested, not where it is kept.

Full methodology
Population history combines DVLA VEH0120 Q4 census observations through 2013 with the annual VEH0220 census from 2014 onward. Figures before 2014 cover Great Britain only. Historical VEH0120 is used only when its overlapping UK observations reconcile to the current canonical family definition. Vehicles are grouped into this family using the DVLA GenModel together with durable routing rules for known inconsistencies.
Variant figures are parsed from raw DVLA model descriptions and the original string is always retained. Configuration is only assigned where the model description explicitly identifies it; a blank configuration is not treated as a two door Wrangler. Blank transmission fields are shown as manual because DVLA records the field for automatic vehicles.
MOT figures count tests, not vehicles, and geographic figures count each vehicle at its most recent test location. The decline projection is a straight line fitted to the latest five years and is illustrative only.
