In the wake of the Volkswagen dieselgate scandal, automobile emission testing procedures have been tightened and all European original equipment manufacturers (OEMs) are now mandatorily required to implement real driving emissions (RDE). By September 2017, RDE testing will have a conformity factor of 2.1. This will change to 1.5 by September 2021 meaning that OEMs will be more forthcoming when it comes to their testing methods and results. After the implementation of RDE, the adoption of World Harmonization Light Vehicle Test Procedure (WLTP) is expected to be simpler.
Currently, the European Union is focusing on global standardization of testing procedures. I tis expected that the use of testing procedures like WLTP, RDE, and New European Driving Cycle (NEDC) will help organizations like the United Nations Economic Commission for Europe (UNECE) and Automobile Manufacturers’ Association (ACEA) to regulate and lower emission levels for all OEMs even in areas that are highly urbanized.
Frost & Sullivan Mobility Research Analyst Arvind Noel Xavier Leo said that shifting from NEDC to RDE is a critical step as the real driving conditions are expected to have a greater impact on powertrain technologies. OEMs will need to look at have to look at optimizing current technologies and explore the development of alternative technologies in order to meet the requirements of the RDE testing procedure.
Frost & Sullivan’s research found that the RDE phase-in and NEDC-WLTP dual testing is likely to implemented by 2017 in the EU. Other markets like China and California will implement WLTP/RDE only after its implementation in Europe.
One of the biggest reasons for delay in the adoption of advanced powertrain technologies is the high costs involved. Technical service providers like Bosch, Continental AG, Ricardo and ICCT need to ramp up their technologies to examine and certify OEMs’ vehicles.
“OEMs are investing heavily in developing low production cost technologies to be implemented in their fleet. Adopting WLTP/RDE will drive improvements such as downsizing, multiple boosting systems, direct injection engines, hybridization and exhaust systems,” noted Leo. “OEMs will look to optimize these technologies to obtain uncompromised results in RDE.”
