Coefficient of drag: 0
Frontal area: 0 sq.ft. how do I determine these? what is my combined epa mileage? 2003 mustang gt manual anything else I should know about the calculation tool? |
I googled all of those things for my car, and found several places that gave the same numbers. EPA.gov will give you your mileage ratings.
:) |
still cannot figure frontal area and epa combined, do i simply just combine and divide by 2? lol
|
|
i found the 15/23 but is combined just the average? and i found the .36 cd, but what about the frontal area?
|
Combined is usually NOT the average, it's a number derived from EPA tests. Combined means some highway, some city, and it's from testing that they get the number. You might have to search the internet awhile to find it.
Frontal area isn't super important for the fuel log, you can go without it and it won't hurt anything. Other than that you will just be searching a lot to find it somewhere. Good luck |
Also: The EPA combined estimate is really just, well, an estimate. I don't think I've ever gotten an exact number of miles per gallon (IE there are always decimals in there.)
The EPA rounds their numbers, so it's just a guideline. You could probably just make up a number that sounds reasonable, there's no harm in that. I don't think you'll be able to find a combined number because the EPA testing was different when that car was being tested than it is now. 18 or 19 MPG would probably be a realistic combined rating. |
thanks

For that info I'd first recommend looking in our wiki:
Vehicle Coefficient of Drag List - EcoModder What we have on the list is a SVT Mustang Cobra 1994 - 2004. Cd is .37 and Cda is explained at the top of the page. For that vehicle is 7.99. |
SON1C, combined EPA estimate for your 2003 Mustang GT manual is 19 MPG.
EPA website BTW, welcome aboard, fellow Mustang owner. |
thanks guys, and dave i imagine we're a rare breed on this site?

Some seem to give up after a few fills when they learn that there is no "magic bullet" for better fuel economy. That's not limited to Mustang owners. It takes some time and effort to adjust the "nut behind the steering wheel", but that's where some of the largest fuel economy gains can be made. Adjusting one's commuting route can also yield significant gains, in my experience. Best of luck with your Mustang fuel economy project. :thumbup: |
