Roof racks
Does anyone use their roofracks? I have never had anything on mine and I am thinking of taking them off and leaving them in the garage.
Just wondering what increase this may have in gas mileage. It certainly can't hurt to eliminate that source of drag.
Anyone done this experiment yet?

Re: Roof racks
I don't know but I'm hoping someone will provide an answer. I have a 2001 Honda CRV with roof racks and I'm guessing that I'd see about a 1-2 mpg increase if I removed them for long trips. I do use them occasionally (about twice a year) and I'm thinking that it's likely that I'm paying a dear price for leaving them on all the time.
If I only remove the cross bars, it would be easy to do and I think most of the drag is from them.

Re: Roof racks
Yeah, I am only talking about removing the crossbars as they are pretty easy to remove. I have never had anything up there and doubt I ever would.
I am going on a 100 mile trip on Sunday so I think I will take them off before I go. I'll see what happens. It will probably only make a difference at highway speed when drag really kicks in.
Every little bit helps. (I wonder if I could get by without those pesky side mirrors?)

I picked up a set of Yakima "Mighty Mounts" to attach my ski rack to.
The mighty mount system worked well on my RAV4 (now my wifes RAV4), so I figure the appropriate adapter's for the FEH should work just fine.

Re: Roof racks
I have a toyota Prius which comes without roof racks. I bought some racks for my kayak, but I only have them on when I am carrying the kayak. I did an experiment and decided to go a week with the racks on to see if it lowered my mileage. The difference was huge. About 3 mpg lower with the racks. Hope this helps.

Re: Roof racks
The cross bars are easy to remove. I take mine off sometimes on my 250-mile drive to Tahoe and put them back on when I get there to carry an inflatable kayak in the summer and skis in the winter.
I also have side step bars. They're useful for loading the kayak, but I did not need them for the skis this past winter. I'll probably remove the bars at the end of the summer.

Re: Roof racks
There was a time when any Italian race driver would rip rear view mirrors off before the race, his only concern was to pass those in front of him. I supose that would be a poor attitude for a Hi-Miler though.
Please post the results of your experiment and whether it was a fast trip or slow one. I'm sure you're right about the drag only being significant at highway speeds. I suppose auto makers will eventually realize there is a significant gain in milage that could be made by streamlining the underside of automobiles.

I haven't noticed a huge mpg difference. Maybe .5-1mpg....but then again mine is just breaking in, so I don't know if this is due to the rack or the engine. I also don't drive a lot on the hwy...where you'd get more benefit out of the roof rack removal.
I have noticed a big 1-2mpg decrease with the use of A/C (even the normal re-circ that shuts the engine off).

Re: Roof racks
I took off my rack the day I bought it and I also removed the attenna (I hate radio). I put the attenna back on now mainly to keep the little woman entertined when she is driving, but I have repalced the rack with Yakima landing pads and crossbars, which are removable when not in use. I don't think it has effected my mileage at all.
