So I am starting to commute about 60 miles per day which 50-55 of those miles are freeway. I am looking to get some feedback on the aero mods I am planning and which I should do first and help calculating the potential end result. I would like to get to 35mpg at 55mph which is more possible than you may think as this comes with the engine that can switch to v4 mode deactivating the other 4 cylinders.
100% stock I get about 25 mpg on the freeway but it gets in the 30's in v4 mode and I average 18.6 mpg combined city/hwy.
Mods I have already done
- I removed the roof rack which moved my freeway mpg to about 26 mpg hwy at 55 mph. So +1 mpg.
I also noticed that the car was in v4 mode more often than before.
Here are the removal mods I have planned
- Lower air dam is 78” long and 4” tall making it 2.17 SQ FT
- The side mirrors are each about 1 SQ FT so together they are 2 SQ FT
- Roof rack is 6' x 2" which is about 1 SQ FT. (Done)
Altogether this will be about 5 SQ FT of reduced frontal area.
Other Mods
Now removing the front air dam is obviously going to expose the turbulent underside of the car and expose the tires so I have a 4" lowering kit in mind effectively putting it at the same height as before.
I also have a coroplast flat bottom planned and I will replace the side mirrors with rearview cameras and 3d print the housing designed like an airfoil.
Am I missing anything and what do you think the outcome will be?
