Citroën has officially released everything its got on the C5 Airscape Concept that leaked out a few days ago, and it turns out our guess that it incorporated a soft top beneath its tonneau cover was wrong. The C5 Airscape will actually shade its occupants with a folding hard top made out of lightweight, strong and certainly expensive carbon fiber.

Billed as an "executive cabriolet", the C5 Airscape is a four-seat hard-top convertible with expressive styling that looks less like a concept and more like a production ready prototype. Its length is accentuated by a sharp crease running the vehicle's length that also incorporates a strip of chrome acting as a door handle for both sets of doors. The cabin is covered in rich looking Chocolate Brown leather and reportedly features just as many chrome accents as the exterior, though Citroën didn't provide any interior shots.

The concept rides on unique 19-inch alloy wheels that are turned by a 2.7LHDi V6 engine producing 208bhp and augmented by what Citroen calls an 'UrbanHybrid' system. Much like the mild hybrid system used by GM, Citroën's set up incorporates a reversible alternator-starter and super capacitors that can both power accessory systems like the A/C and stereo, as well as give the diesel engine a shot of extra torque when needed.

The C5 Airscape will officially debut in Frankfurt next month and gives us a preview of the new C5 sedan, which we expect to meet next March in Geneva.
