Citroen C4 / Overview / Efficient engineering

Citroën has utilised the latest industrial technologies, along with a 'part by part' focus on reducing the weight and number of components in new C4. For example, the laser welding on the roof and doors saves 2kg and new C4's steering wheel saves 3kg compared to the 'fixed' hub steering wheel on the previous model. Controlling new Citroën C4's overall weight has helped to deliver safer and more responsive handling whilst reducing fuel consumption and CO2 emissions.

New Citroën C4 also demonstrates Citroën's expertise in engineering efficiency with every effort made to minimise the model's carbon footprint in the production process. A record for the PSA Peugeot Citroën Group, 15% of new C4's polymer components are made using 'green' materials such as re-cycled plastics, natural materials (e.g. cellulose fibre) and other bio-materials from non-fossil, renewable sources. In all, thirty individual parts, including the rear bumper, door panels, carpets and wheel arch liners use these 'green' materials. New C4 is also 85% recyclable.
