Weight Reduction for better FE

[skale7]

In an ideal road, yes. However, there are stops and starts, places where you have to change speed, bumps, etc. While driving technique can help negate the ill effects of extra weight, removing weight cannot hurt. At least, you might not have to downshift as often on steep incline.

My driving is also mostly hilly city driving, so it would have a more significant effect.

Also, gas will be saved on those occasions where you cannot drive efficiently, such as stop and go traffic.
