Citroën Osmose City Car II

Citroën Osmose City Car II — a prototype electric microcar seemingly named after an earlier Citroën concept. Presented in 2004.

Constructed from Kelvx thermoplastic resin, it featured an electric drivetrain powered by a removable battery pack, allowing one unit to charge while the other was in use.

Its standout feature was a pair of rotating doors that opened by pivoting a full 180 degrees.

Showcasing the material’s versatility, even the windows were made from Kelvx.
