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
