The introduction of the Worldwide Harmonised Light Vehicles Test Procedure (WLTP) and Real Driving Emissions (RDE) test requirements have put increased strain on vehicle and engine performance as well as the development of advanced engine technologies and emissions mitigation strategies. This requirement for increased development is a direct result of the need for new vehicles to comply with present and emerging emissions standards across an extended range of boundary conditions that include ambient temperature, altitude and driving style. To reduce the significant number of on-road test permutations that would ordinarily be required to validate a given vehicle across the defined RDE boundary conditions, a Road to Rig (R2R) development approach known as RDE Plus (RDE+) is being evolved at HORIBA MIRA.
