The adapted test will recreate a ‘real life’ mix of urban, countryside and motorway driving in a bid to reduce harmful emissions from car exhausts

All new models of diesel and petrol cars will now have to pass a stricter emissions test before they can drive on Britain’s roads from 1 September 2017, the Department for Transport has announced.

The reformed 90-minute test indicates the toughest overhaul of emissions testing in many years, as the previous rolling road test has been scrapped in favour of a ‘real world’ approach. The changes will slash harmful nitrogen dioxide emissions by two-thirds for diesel cars, in line with European-wide reforms.

During the test, the vehicles will have emissions testing equipment attached to the exhaust pipe and will be required to drive roughly equal splits of town, countryside and motorway. They must pass before they are approved to go on sale in Britain. The test will be extended for all new cars on sale in Britain from 1 September 2019, with new nitrogen oxide emissions requirements for all new car models becoming stricter again the year after.

Transport minister Paul Maynard said: “We are taking strong action to clean up our air, and these tough new emissions standards will reduce dangerous pollutants. This will ensure all vehicles meet rigorous standards when driven on our roads – and we are going even further tightening requirements again in 2020.”

These changes come after the government’s review of the diesel testing programme found Euro 6 diesel cars were emitting six times more nitrogen dioxide in the real world than in the lab. These reforms will mean the figures will decrease by two thirds, and will help tackle air pollution in towns and cities across the UK.
