Thumbs up Front Air Dam ABA test results: 7.49% increase in MPG at 60 mph (2003 Honda Civic DX)





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!

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.

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

Nice work. Thanks for the report.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

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?
