Fuel saving car (mainly motorway) 27,000-30.0000 km per year

A nice day, I have been thinking about a new car for a few weeks. New in the sense of new or well used. I have been driving a Suzuki Splash ex 1.0 liters and 65 hp since 2011 and my car has also been victim of driver flight. As mentioned above, I drive a lot of highway. Every second day it is 140 km via highway and city traffic. Of course I don’t need to talk about having a huge spirt consumption. And I would like to change that and also etraglic Of course there is a wide range of car models. In order to gain an overview of which car also makes a good “sprit figure” on the highway in contrast to my current car, I need your help/opinions. Because I am a small woman, it should of course not be a combo πŸ™‚ and no Mini/Fiat 500. My price limit is 16,000 Euro (new/needed). Of course there are also various features to this (parking assistance front/backside zb.) What for brands kΓΆ nnt you recommend me, which are also not very reperature prone. Electric car does not come for me question, also certainly does not fit in my budget. I look forward to your feedback.
