The latest generation of diesel cars emit low levels of NOx emissions on the road, according to data from the European Automobile Manufacturers’ Association.

This data was measured in real-driving conditions by the drivers from national type-approval authorities.

Some 270 new types of diesel cars type-approved against the latest Euro 6d-TEMP standard were introduced in Europe during the past year.

The new data shows that all of these cars performed well below the NOx threshold of the real driving emissions test, which applies to all new car types since September 2017.

In addition, most of these vehicles already show results that are below the stricter NOx threshold that will be mandatory from January 2020.

Association secretary-general Erik Jonnaert said: “These new findings prove that modern diesel cars, supported by fleet renewal policies and combined with alternative powertrains, will play a strong role in helping cities move towards compliance with air quality targets.

“In parallel, diesel vehicles will continue to remain important for reducing CO2 emissions in the short and medium term, even though all manufacturers are expanding their offering of electrically chargeable cars.

“Auto makers have made major investments to quickly deliver these massive reductions in NOx emissions.

“It is important that we stop demonising diesel technology as a whole. Instead, we need to differentiate between the old diesel fleet and the latest generation of vehicles.”
