I appreciate this is an old post, but:
I have a 2023 1.6 auto, 72k miles.
Wish I was getting anywhere near that consumption, I've owned it 14 years & have only managed 38mpg on long m/ way runs doing steady 60mph. Normal running about it's 33/ 35mpg.
Compared to 1.4l 16v I had before (38/43.mpg) I didn't think it too excessive. I'm a fairly steady driver eg. I used to get 43/ 58 from my 1993 1.6l cavalier! (Wish I'd still got it: utterly reliable & almost faultless).
What's your secret LOL?
