Hi Guys, first post here!
My wife has a Fiat 500X 1.0 120hp gas, and she usually only drive in the city... she drivees between 10-20km/day. The car is consuming 8,6l/100km, isn´t this a bit too much? Can you maybe share your expiriences.

Thanks!

8.6l/100km is 32.8mpg which I would say is OK. I get about the same (often slightly less) from my 500X 1.4. for similar city driving and short distances.

Car weights and drags will be about the same as will engine efficiencies (in round numbers) so I don't think you have a problem.
