Citroën should be one of the few remaining carmakers who believe that concept cars must deliver shock and awe above all – their recent creations like the GTbyCitroen, Revolte and the Survolt from Geneva look like beings from another planet. Their latest concept, Metropolis, takes all that wackiness and puts it in a limo body.

The French carmaker says that the Metropolis “pays homage to China’s extraordinary development” and reflects China’s “avantgarde status, grandeur and vitality”. What? Created by Citroën’s international design team – based in Shanghai since 2008 – the Metropolis will be on show in the French Pavilion at the 2010 Expo in Shanghai from 1st May to 31st October this year.

The Metropolis’ silhouette is imposing (5.3m long, 2m wide, 1.4m high), blending taut lines with smooth surfaces. Up front, the sculpted wings and kite-shaped grille hint at recent Citroen concepts. The headlamps have an “imperious and steely look” according to its maker. At the rear, there’s an active spoiler and Citroën’s signature concave rear window. Wrapping up is a ‘Pearl Silk’ body colour that changes under different light conditions.

This car is a plug in hybrid which consists of a 2.0-litre V6 petrol and a 7-speed, dual-clutch gearbox. At low speeds, the limo runs in zero emissions mode, its electric motor developing a continuous 55 bhp, peaking at 95bhp. At steady speeds, the engine provides 272 bhp and 375 Nm. When additional performance is required, both sources combine for 460 bhp and 430 Nm of torque channeled to all wheels. The Metropolis sits on Citroën’s Hydractive suspension, of course.
