New regulations in the EU mandate testing under “real-world” conditions
Your business challenges
Regulators around the world are setting new, more stringent standards for automotive fuel efficiency and vehicle greenhouse gas (GHG) emissions. As such, improving vehicle mileage and reducing harmful emissions are critical innovation challenges facing the automotive industry. Emissions and fuel economy testing is required not only to demonstrate compliance with current requirements but are also essential tools in the development of new automotive technologies in these important areas.
However, in recent years, comparisons of laboratory-based test results with those from on-road testing have shown a significant and growing gap between reported and actual carbon dioxide (CO2) emissions and actual fuel consumption. The most prevalent explanations for these discrepancies include shortcomings in the testing schemes used to evaluate fuel efficiency and emissions levels, and variations in the interpretations of requirements by testing laboratories. As a result, actual vehicle performance often falls far short of regulator-imposed requirements as well as consumer expectations.
The EU’s RDE and the WLTP
The intent of the European Union’s new real driving emissions (RDE) testing regulations is to validate under real driving conditions emissions levels as measured in the laboratory. RDE testing involves the use of portable emissions measuring systems (PEMS) that is attached to the vehicle under test. The PEMS measure pollutant emissions while the vehicle is driven outdoors in daytime traffic according to random acceleration and deceleration patterns. RDE test results are then correlated with emissions results obtained in the testing laboratory.
Testing under the EU’s RDE is now required, although testing is currently being conducted solely for monitoring purposes, and a determination of vehicle type approval is based exclusively on laboratory measurements. However, effective 1 September 2017, type approval requirements must also consider emissions levels identified during RDE testing. As a result, vehicles that fail RDE testing from 1 September 2017 may not be permitted to be placed on the market.
Why choose TÜV SÜD?
TÜV SÜD’s accredited, state-of-the-art testing facilities are located near major automotive development centres around the world. Each testing facility is equipped to conduct all essential emissions and fuel efficiency tests required for passenger and commercial vehicles and motorcycles in accordance with industry requirements, as well as national regulations and international standards, including the EU’s RDE and the WLTP.
TÜV SÜD is also actively working with partner testing laboratories in China, South Korea, Japan, Taiwan and U.S. to more closely harmonise emissions testing procedures. The goal of TÜV SÜD’s round robin testing programme is to reduce to the extent possible the number of variables that can affect testing outcomes, thereby helping to ensure consistency in emissions results generated by multiple laboratories testing the same vehicle.
With our round robin testing programme, TÜV SÜD offers automotive manufacturers worldwide harmonised emissions and fuel efficiency testing, reducing the time and expense associated with obtaining global regulatory approval for new vehicle models. The round robin testing programme is just one example of TÜV SÜD’s century-long commitment to supporting the automotive industry with innovative programmes and testing solutions that can address their regulatory compliance challenges.
Testing under the EU’s RDE must also follow the procedures detailed in the Worldwide Harmonised Light Vehicle Test Procedure (WLTP), a core element of Global Technical Regulation 15 (GTR 15), which was approved in March 2014 by the EU, China and nine other countries. The goal of GTR 15 is to provide worldwide harmonised test procedures that can evaluate in a repeatable and reproducible manner emissions levels for a variety of pollutants as well as fuel and electrical energy consumption.
