ABA test today was as follows:


I used the same 4mi. course that I did for my wheel covers. 2mi up, 2mi back, then averaged. Speed was 60mph, windows up, A/C off, radio off, fan on.

(Without Air Dam)
A1: 45.10mpg
A2: 44.45mpg
A3: 44.50mpg
AVG: 44.68mpg

(WITH Air Dam)
B1: 47.80mpg
B2: 48.25mpg
B3: 48.05mpg
AVG: 48.03mpg

(Again, without)
A1: 44.75mpg
A2: 44.6mpg
A3: 44.5mpg
AVG: 44.62mpg

I took the average of the closer results: 48.03mpg is a 7.49% increase over 44.68mpg!

Well done! Makes me that much more motivated to make one of my own.

That is one of the largest improvements that I have seen for almost any modification.

Sounds like my experience with airdams...
I have observed between 5%- 15% increases, between a few differant cars.

Added photos from the build thread.

Thanks for doing the testing - it's time consuming, but worth the effort.

Just this morning I realized I'm going to have to test it again after I do full belly pans for front and back to see if it is "needed" at that point. Oh, joy. :)

It actually didn't take that long to take off or put back on, maybe 10min?

Yes, but will you do A-B-A with the belly pan?

I do not think that any of us will blame you if you forgo it.

Got a question. I have a 2012 Chevy sonic turbo sedan. I was wondering if a air dam is better to have than full under body panels? I'm thinking underbody based off of knowledge I have gathered from this site and others. Could some confirm this for me?
