Real Driving Emissions (RDE) testing is a methodology used to measure the emissions of vehicles in real-world driving conditions, as opposed to laboratory testing. The goal of RDE is to provide a more accurate and representative picture of vehicle emissions, which can vary significantly depending on factors such as driving style, road conditions, and ambient temperature.
RDE 3.1.7 refers to a specific version of the RDE test procedure, which is outlined in the European Commission's regulatory framework. Specifically, RDE 3.1.7 relates to the third package of regulations (hence "3.1.7") that aim to tighten emissions standards for vehicles sold in the European Union. rde 3.1.7
The RDE test procedure involves equipping a vehicle with a Portable Emissions Measurement System (PEMS) and driving it over a specified route that reflects real-world driving conditions. The PEMS device measures the emissions of the vehicle in real-time, providing a detailed picture of emissions over a range of driving conditions. Real Driving Emissions (RDE) testing is a methodology
