I've been driving my 4R without the top since the weather has been so nice here. To my surprise, the mileage has jumped a bunch. Not sure how much just yet, but the number of miles I get on a full tank has already rolled by and I still got a 1/4 tank left. Anyone else notice this with their 4R?

Removing the canopy on my 22R 1989 truck increased the mileage a bit if I remember correct.

You'd think it would kill the aerodynamics.

maybe its a wieght loss thing?

i agree with BigBluePile...
cuz a 4 runner top weighs a couple hundred pounds?
it is fiber glass it's not the lightest thing, especially since there's 6 windows in it too. it would make sence that you got a bit better milage.

You women are imagining things. The gas mileage increase is probably cause you are driving more modestly and slower trying to act cool cruising around the soccer moms at the mall.

Shhhhh, don't give away the secret.....!

The numbers are in -- the truck gained 1.5mpg with the top off.

I noticed that with my 4Runner this summer too

Makes sence.. Removing a few hundred lbs helps mpg. I wonder if it creates a similar "vortex" in the bed like a pickup does... That might help too...

I want to make a fastback-style soft-top. I imagine that would probably be good for additional mileage.

you would probealy be better off with buying one, it is really hard to make your own, you need special equipment

before you start, search so you can see the other people who tried and not make the same mistakes

why is it hard for me to picture a 4runner in a wind tunnel?

don't make me go in to negative pressure and bernoulli effects, etc.

First time ever I had mine off. I feel sooo.......naughty.



I also threw on a little "sumtin" "sumtin" this weekend...
