Hi all, first post here. I have a '12 Chevy Cruze Eco MT and so far I am very impressed with the mileage as well as the car. For a car used ~95% for commuting it is really working out well.

I looked through your list here and didn't see any info for the Cruze so I thought I'd make a contribution:

Width = 1796mm/70.7in
Height = 1476mm/58.1in
Height = 1466mm/57.7in (Eco/RS*)
Cd = 0.331**
Cd = 0.298 (Eco)

Doing the math I get a CdA of 7.649 for the standard Cruze, and 6.839 for the Eco.

*- Eco height is standard car height -10mm; I couldn't find a spec for the Eco height but it uses the RS package springs making it 0.4in/10mm lower than the standard car.

**- Eco Cd is 0.298, according to GM this is a 10% improvement over the regular Cruze, so 0.298/0.9 = 0.331

EDIT: Added 0.81 correction factor to calculations
