History of the Citroën C1
2005: one car, three badges
The C1 was developed alongside two badge-engineered versions: the Peugeot 107, almost identical apart from the front bumper and lights, and the Toyota Aygo, slightly more different. All three appeared at the 2005 Geneva Motor Show and were built by the TPCA joint venture in Kolín in the Czech Republic. The body was designed by Donato Coco in a one-box shape, and on the C1 and the 107 the tail light cluster ran from the edge of the rear doors to the rear window without a clearly expressed C-pillar. Power came from a 1.0-litre three-cylinder petrol engine or a 1.4-litre four-cylinder diesel, quoted at 4.6 and 4.1 litres per 100 km on the EU test; the German magazine Der Spiegel rated the C1 the production car with the second-best fuel economy among petrol engines, after the Toyota Prius, and among diesels, after the Smart Fortwo mhd.

Recall, racing and special versions
In January 2010 PSA recalled around 100,000 C1s and Peugeot 107s after Toyota’s worldwide recall for a sticking accelerator pedal. The C1 also became a popular cheap racing car for endurance events, in the spirit of its 2CV ancestor. British trim levels ran from the basic Vibe through Rhythm and Code, and special editions included the Cool and the Airplay, the latter with iPod connectivity revealed at the 2006 British International Motor Show. Franco Sbarro built a one-off GT-C1 with gullwing doors, very wide wheels, a 1.6 engine from the C2 VTS and C4 WRC-derived brakes, while in Portugal and Greece a three-door diesel van called the Entreprise was offered. From 2009 to 2012 the Electric Car Corporation of Britain sold an electric conversion, the C1 ev’ie.
Three facelifts
The car was facelifted in January 2009 along with its sisters, with a new bumper and grille, revised trims — Vibe became VT and Rhythm became VTR — and a revised clutch. March 2012 brought another facelift with LED daytime running lights, a new steering wheel and better economy, plus the Platinum and Edition trims and later the Connexion; in Greece the car was rebranded C1 eco between 2012 and 2014. Reliability data from the German automobile club in May 2010 put the C1, 107 and Aygo at the top of the sub-small class for low breakdown rates at one to four years old, but the Euro NCAP score fell from four stars to three in the 2012 assessment.
