Following significant criticism of the wildly unrealistic European claimed fuel economy figures that car manufacturers publish in their literature, the official test is set to be completely changed from 2017 onwards.
This comes after the European Commission approved a new ‘real driving emission’ (RDE) test, after widespread complaints that the current ‘NEDC’ official fuel economy test gives little indication of the real-world economy figures that buyers can expect to gain from their cars, with the test carried out in a lab, negating the effect of wind resistance and other forces that increase fuel consumption, artificially increasing figures.
This new rules, which will be implemented from 2017 onwards, will see all cars sold in Europe put through the RDE test, which is set to include some ‘real-world’ driving, reports Motoring Research, with cars fitted with portable emissions measuring tech.
This will signify the first time that emissions figures will be measured in the real world, rather than just in lab conditions, and as a result, buyers should gain a much greater idea of the fuel consumption to expect from their car.
We need to make more progress on clarifying all testing conditions to ensure a robust RDE regulation could commence from September 2017.
Following increasing concerns over nitrogen oxide emissions (NOx), the Sunday Times and Emissions Analytics have also discovered that a number of diesel cars which meet the latest Euro 6 emissions standards produce far more NOx in real-world conditions than the official tests, typically emitting far more than the official limit in the real world.
Car manufacturers do still have worries over the form that the new test will take. Secretary general of European car manufacturers’ association, ACEA, Erik Jonnaert said: “ACEA calls on the Commission to urgently deliver a complete proposal for Real Driving Emissions by June or July at the latest for a positive decision in the regulatory committee."
“We need to make more progress on clarifying all testing conditions to ensure a robust RDE regulation could commence from September 2017.”
