I poked around but could not find it quickly...

what mpg are you getting cruising at 55? here in upstate ny, many highways/parkways are 55 and i was just wondering what I could be getting....

 

around that speed your looking into the 40MPG area.
i cruise just under the 60mph mark and i get an avg of
39-42 mpg at those speeds. this is all hand calculated also.

 

with my scanguage, i was cruising at 60 mph and getting 50 mpg. but im really low. so less air resistance. so you should be getting around 45 mpg

 

you cant say anything for sure. every second of driving is different

 

Why so?

Air resistance is defined by coefficient of drag times frontal surface area, which for both cars would be identical. The fact that your car is lowered may or may not help overall air resistance.

Maybe if it's lower, less air is able to bypass it underneath creating extra pressure in the front forcing air to go around and above the body. But maybe less air under the car also means less turbulence...

I think it's hard to say. What's your reasoning?

 

most def. just looking for approximation


thanks for the replies..

 

idk.. but i have a scanguage and i noticed an increase in mpg after i lowered my car

 

my gas mileage improved as well after lowering my car.

 

Good logic I think
Now consider that the bottom of yer car (with all the chassis parts, exhaust etc) is the least aerodynamic by a fairly large margin.

 

how many miles did you have at the time?
I heard from many gd owners that 10k is the final mark where the mileage peaks and holds. perhaps the ge is similar.

also, what was the increase? thanks.

isn't that why body kits were originally designed for? air flow? I remember top gear mention something like this...
