Euro 6 Diesels - Cleanest in History

Almost one in every two new cars registered in the UK is a diesel. In 2016, a record 1.3 million new diesel cars were registered in the UK. Overall, more than 99% of the UK’s 4.4 million commercial vehicles are powered by diesel.
But, there is pressure now on diesel drivers to give up their vehicles in a bid to lower pollution levels, especially, emissions of nitrogen oxides, or NOx emissions. But, contrary to recent reports, diesel cars are not the main source of urban NOx. In fact, in London, gas heating of homes and offices is the biggest contributor.
Diesel is critical to reducing CO2 emissions, as diesels on the average, emit 20% lower CO2 particles than their petrol equivalents. On average, they use 20% less fuel than like for like petrol models. Buyers value these low fuel consumptions.
Advanced diesel technology has virtually eliminated emissions of particulate matter, with 99% of these soot particulates captured by special filters. As well as special filters, the latest Euro 6 vehicles also feature technology that converts most of the NOx from the engine into harmless nitrogen and water.
Mike Hawes, SMMT Chief Executive, said, “Euro 6 diesel cars on sale today are the cleanest in history. Not only have they drastically reduced or banished particulates, sulphur and carbon monoxide but they also emit vastly lower NOx than their older counterparts.
This has been recognised in London, where drivers of these vehicles will be free to enter the Ultra Low Emission Zone that will come into force in 2019 without charge. “Some recent reports have failed to differentiate between these much cleaner cars,” notes Hawes. “This is unfair and dismissive of progress made.“
