It's a valid question. A 5+ year older vehicle, with a 5 speed auto, and 1.8L engine that gets almost 10% better fuel efficiency? Something's wrong with that math IMO. [same driver (me), same routine, same gas stations/fuel source, etc]
I'm not saying I dislike my Sonic, but this is an obvious fault in a fundamental area (especially for this class vehicle).
Let the GM rep decide if it's a worthy post to reply to.
is having cruise control give you better gas mileage in either the 1.4l or 1.8l and does it matter if it's auto or manual trans. my 1.8l auto sonic sedan doesn't have cruise control.
I get between 31-36 mpg 70% city .
I have way too many stop and go's in my town and a bunch of idiots that cant drive so that is impossible in my town. I average around 20-25mpg in the city only. Sometimes i hit 28mpg... Highway ive hit as far as 34mpg with my 1.8 Sonic so far. This summer i will be seeing just how well it really does.
Your numbers are not that bad honestly .
This might sound likea stupid question, but anyway. How does the sonic configure its mpg that are displayed!? Ive seen in different cars that it changes allmost every second. But mine barley ever changes.
Have you reset it? This car will read out till you reset it manually. The longer you leave it without resetting the less it will show you instant readouts.
