What can I do if the vehicle is not getting the advertised mpg?
The 'New European Drive Cycle' (NEDC) tests used to calculate an mpg figure for each vehicle are carried out in test conditions. Although the mpg can be used as a guide to help you compare cars, the actual mpg each car achieves in real world driving is likely to be lower than the official figure. Visit our fuel efficiency page to find out how the official mpg is calculated.
The mpg achieved is impacted by many factors such as driving habits, weather, traffic and road types. To maximise your fuel efficiency, you can follow our greener driving tips .
