What does it cover?
UN R168 defines harmonised methods for measuring real driving emissions of light vehicles. Gases, particles, measuring instruments, road conditions and data analysis form part of the test process. Pure electric and fuel cell vehicles are outside its scope.
Who is it for?
For vehicle, engine and powertrain manufacturers and measurement, testing and approval teams.
Which subjects are addressed?
- RDE vehicle scope and approval levels

Common question
Is the RDE test also performed for purely electric vehicles?
The scope of this RegsUP edition excludes pure electric and fuel cell vehicles. Other powertrains require vehicle category and the relevant approval level to be read together.
