The Citroen C1 is a small city car on sale since 2005. The car was created by the joint efforts of two corporations - PSA (Peugeot and Citroen) and Toyota, which resulted in three identical cars - Peugeot 107, Citroen C1 and Toyota Aygo. The biggest differences between cars are in the group of headlights, interior design, rear of the car and logos. Cars are made with three- or five-door hatchback bodies. There are two engines - a 1.0 L three-cylinder engine with 68 hp (51 kW) and a 1.4 L HDi diesel I4 engine with 54 hp (40 kW). The car is rated 4 stars in EuroNCAP safety ratings. According to Spiegel magazine, the C1 ranks second in terms of economy among petrol engines (after the Toyota Prius) and also second among diesel engines (after the Smart ForTwo).
