The original C1, launched in 2005 as one of three near-identical cars built side by side at a joint-venture factory in the Czech Republic, the others being the Peugeot 107 and the Toyota Aygo, whose engine the C1 also uses.[1] It became an unlikely fixture of amateur endurance racing, cheap and simple enough to run for 24 hours the way owners once raced the 2CV.
Fuel economy for both engines is a genuine self-contradiction in the source, not a disagreement between two references: the article’s own body text gives one figure (marked “citation needed” in the underlying wikitext) while its engine specification table gives a different, more specific one for the same engine. Both are recorded in the note; the table figure, being the more precisely attributed one, is the value stored.
