The Dedicated Exhaust Gas Recirculation System (EGR) solution was also present and is designed to improve petrol engine efficiency and deliver significant fuel savings.

PSA also showed its Hydole, plug-in hybrid demonstrator, which mainly works on electric but helps allay driver concerns over driving range, comfort and affordability.
