Subaru XV 2018 (new model) – Fuel consumption in motorway operation

Hello, I would like to get a XV 2.0 of the current series. What is causing me a bit of a headache is the fuel consumption. The few available information sources give here unfortunately only a mixed and also diffuse picture. The corresponding factory data are anyway not realistic with any manufacturer any more. Test consumption in car newspapers are indicated with 8.5 – 9.5L resp. 12.5L highway >160Km/h With fuel monitor the new XV ́s are currently at 8,9L, the number the participant is still small. (according to the experience with fuel monitor rather consumption-oriented participants publish their values) I would operate the vehicle mainly on motorways with moderate traffic and usually with cruise control at 150 – 160 km/h – a usage case, which is shown so nowhere assessable. Is there any experience in the forum? What does the consumption indicator show for the level running at 130 / 150 / 160 / 180 km/h? What do you have for Realve customs after motorway rides (and at what average speeds)? Thanks & Greetings, Flyerbo
