Just saying that I bought a used LTZ 1.4 6mt hatch about 2 weeks ago. I reset the MPG meter a few times, latest was this AM heading to work. I hit pretty heavy traffic, stop and go. Some sections were very slow like having to wait 2-3 cycles to get through a light slow. I also hit stop and go and slow going on the main hwy. But it also opened up and some of my drive is at 60-65, sea level in Houston temp was about 45 F.
What blew me away was after this not so great traffic conditions, I got to work and the cars DIC shows 41mpg! Holy cow. Impressed. On the way home I take different route as I have a club meeting in town. I drop by Costco and get a few things, refuel. My fuel light was on. The pump shut off at 10 gallons! The guy next to me was in a huge Ford 150 Raptor SVT with the 6.2 engine. I was giddy, my fuel bill tiny, I was laughing out loud as I got back in the car.
I got home and my MPG was still over 40. I'm impressed. We had rented a 1.8 sonic and it was OK but had less power and got less mpg. Love it!!
