Securing a sustainable future

In Europe, the development and implementation of new regulatory test procedures including the chassis dynamometer (CD) based World Harmonised Light Duty Test Procedure (WLTP) and the road-based Real Driving Emissions (RDE) procedure, has been driven by the close scrutiny that real driving emissions and fuel consumption from passenger cars have come under in recent times.

To build understanding of the emissions and fuel consumption performance of the latest available diesel passenger cars, Concawe has conducted a study of the performance of four vehicle types over a range of test cycles.

Upon the request of Concawe, Coryton provided a pair of diesel fuels blended to have distinct physical properties, which could be expected to behaved differently over the new, RDE, test cycle.
