Citroen C-Airdream Concept
The Citroën C-Airdream was a concept car created by the Citroën division of PSA Peugeot Citroën. This concept car was first presented at the 2003 Geneva Motor Show. The C-Airdream is designed to be very slender and very aerodynamic.
The C-Airdream has a V6 engine with normal aspiration. This engine can produce 210 hp (157 kW) , 72 hp (54 kW) per liter, and 260 N·m (192 lb·ft). The design gives the C-Airdream good stability, roadholding, and adequate performance. It's stability is given by the C-Airdream's "hatchback" rear. The C-Airdream bears a small resemblance to the Citroën C4 as well as the C6 (more notably the C6 Lignage concept).
