What Does The NEDC Measure?

What does the NEDC measure?

The NEDC is an artificial laboratory test that helps compare the fuel consumption of vehicles, without reflecting the fuel consumption of day-to-day driving.


Actual consumption today is often very different from the NEDC information. The main reasons include:


  • The theoretical driving profiles NEDC uses don’t match real user profiles
  • Insufficient acceleration
  • Too many stop-and-go phases
  • NEDC doesn’t incorporate higher speeds, which sets the average speed too low
  • Gear shifting points are broadly defined by transmission type, so they're the same for all cars with manual transmission
  • Optional equipment isn't taken into account
