Why is my Passat's economy so poor?

Hi, we recently bought a VW Passat 1.6 FSI, but the fuel economy is terrible. We seem to be at the petrol pump more often than not. Is this common for this type of car?

Hi Declan,

The Passat is a lot of car for a 1.6-litre engine to pull along, so depending on how and where you are driving it then your fuel economy might not be super. Is the car brand new? In the running-in phase economy can be a bit down on post run-in performance but perhaps have a look at your driving style and eliminate that as a possible problem first.

It is possible on the Passat to look at the instantaneous consumption so keep an eye on that and make a note of it and the average values. 

I've been through enough fuel economy challenges at this stage to know that it can be often down to our own driving (and I include myself) in this. Nobody really needs to 'drive' a tonne-and-a-half car down a hill and being a little more delicate with your right foot can make a massive difference (110- vs. 130km/h on a motorway for example). 

Aside from all that, keep a note of the car's performance over 2-3 days then make a conscious effort to change your driving for the next few and if there is no massive difference then perhaps see about getting the car checked over. 

Come back to us with actual figures, mileage of the car and how it is used and we'll try to give you more assistance.
