I did estimations with tool found here:
http://ecomodder.com/forum/showthrea...ower-6341.html
I don't know how accurate that tool is and how accurate my engine efficiency and tire rolling resistance parameters were, but according to that tool, I should have had
cd of 0.26 or so at last summer with aero mods or perhaps even less.
I had minikamm of crude design, rear wheel well skirts, partial front wheel well skirts, air dam bolted lower edge of front bumper, grille blocks, lower being poorly made.
No any kind of bellypan.
Driving was lights on, so maybe I should input overhead wattage there too (I did add now 150W), which means I should input even lower cd to get fuel consumption to level what I did record.
Stock vehicle has cd of 0.34-0.36, so having it down to 0.26 would be really lot, imo. Especially with quality of mods. What do you think, would it be possible with such mods to lower cd that much?
Link to my results
Results are bit higher, but I estimate some of the effect was hypermiling technique too, still there must have been big effect of aeromods as some trips did not contain hypermiling.
