I'm the owner of a Pontiac Torrent. I've been able to get upwards of 26mpg on the interstate traveling 70 to 75 mph. Not to bad, but I would like to be able to hit 30mpg at times or once in a blue moon. For those that are unsure of what a Torrent is:
As you can see from the image, the air dam on this thing is HUGE!!! Bordering on cow catcher to me. My question is, would I benefit from removing the air dam and replace it with a full or partial belly pan? Or would a combination of both be better? Or leave it alone?
The Torrent is pretty much the same thing as a Chevrolet Equinox. An 05 Equinox, from the research I have done, has a cd of .42 and frontal area of 29.3 sq ft. Some changes were done in 07 to improve on the mileage on the vehicles (larger spoiler, relocated antenna, and I believe a smaller air dam) By removing the air dam, I would think that I would reduce the frontal area by 2 sq ft at least.
So what do you think? Improvement, bad move, not changing a brick?
For those wondering, I removed the roof rack.
