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
