With the emission cheat scandals slowly snowballing into epic proportions, the European Union had to revise their testing procedures. The new process, known as Real Driving Emissions (RDE), has been designed to minimise the disparity between real world and laboratory simulations to test vehicle emissions.
The new rules will be applicable for all new models launched from September 2017 onwards and will be applicable for every new car sold between 2018 and 2019. The car manufacturer’s union had requested EU to defer the implementation of the new rules by three years. But, since the earlier tests have been compromised over the years, pollutants in large amounts have already been spewed into the environment resulting in higher pollution levels.
As a result of the new testing procedures, efficiency and emission numbers of many existing cars are likely to be affected. The new testing procedures will allow little leeway for carmakers to fiddle around to tweak the end results.
