Manufacturers of passenger cars and Light Commercial Vehicles (LCVs) must carry out a series of tests to verify their compliance with regulations prior to placing their vehicles on the market. In September 2019, LCVs must make the transition to one such test.
Since the 1980s, laboratory tests have been used to measure vehicle fuel consumption and C02 and pollutant emissions. The tests follow standardised procedures that can be reproduced, allowing for the comparison of results. Under conditions defined by EU law, the New European Driving Cycle (NEDC) test was based on theoretical driving cycles to test different car models and allow consumers to compare the results.
