WLTP Testing

The WLTP Second Act

The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) came into force for new cars in 2018. Now there have been some updates to the procedure that new cars must go through to be tested; the WLTP Second Act.

What is WLTP?

The Worldwide Harmonised Light Vehicle Test Procedure was introduced to undertake on-road emissions testing for all new vehicles. Previous vehicle testing took place in controlled test facilities, now cars have to be tested in real-world conditions. The aim is to make test conditions to more accurately reflect everyday driving.

What is the WLTP Second Act?

The WLTP Second Act stipulates that as of 1st September 2019, all new cars must be certified to show that they have passed the more stringent version of testing.

This does not require a physical retesting of the vehicle, but instead re-run the results through a stricter algorithm. These stricter rules include an evaporative emissions test, as well as the Real Driving Emissions tests which have been introduced at type-approval stage. These must be passed before a vehicle can be placed on the market.
