Cars and vans to have ‘on-board fuel consumption monitoring devices’ from 2021

Cars and vans to have ‘on-board fuel consumption monitoring devices’ from 2021

All new cars and vans will be equipped with on board standardised and accessible fuel and energy consumption monitoring devices from 2021, if the proposal is adopted by the European Commission.

The proposals comes from the Commission’s Technical Committee of Motor Vehicles (TCMV), which has also outlined a tightening of the new Real Driving Emissions (RDE) standard with proposals for so called RDE3 and RDE4 standards.

Both measures build on the new carbon dioxide emissions and fuel economy testing procedure, the World harmonised Light vehicle Test Procedure (WLTP), and the related RDE1 and RDE2, which specifically measures nitrogen oxide (NOx) and particle numbers (PN) in real-world driving conditions.

In a statement revealing the potential fitment of the new technology to cars and vans, the European Commission said: “Fuel consumption directly relates to the CO2 emissions. The new feature, so called ‘on-board fuel consumption monitoring device’ allows for the first time to compare laboratory results for CO2 emissions with the average real driving situation. This will also provide valuable information to consumers.”

After a three-month scrutiny period in the European Parliament and Council, the Commission will adopt the proposal, which would then apply from 1 January, 2019.”

Meanwhile, RDE3 and RDE4 further refine the RDE1 and RDE2 testing procedures. Specifically RDE4 ensures transparent and independent control of emissions during a vehicles’ lifetime.

Type approval authorities will have to check each year the emissions of vehicles already in circulation - so-called in-service conformity testing. Additionally, taking account of the latest improvements in measuring technology, RDE4 also further tightens emissions standards - known as the conformity factor, which caters for technical and statistical variations in RDE measurements, from 1.50 to 1.43.

The European Commission has said it would continue reviewing the conformity factor with the aim of bringing it down to one as soon as possible and at the latest by 2023. The next reduction is scheduled for 2019.

As with the introduction of ‘on-board fuel consumption monitoring devices’, after a three-month scrutiny period in the European Parliament and Council, the Commission will adopt the proposal, which would then apply from 1 January, 2019.
