Range increase driving with mirrors folded?

    Has anyone done a test to see if the Wh/mile decreases at highway speed with the mirrors retracted? I'm really curious to see if you could fold them to get an extra mile or two in a pinch if you need it.

    I tried it once, but could not detect any noticeable change in the power used per mile on the highway.

    It is noisier, so It's probably worse. They stick out less, but are not as are dynamic when folded.

    This is kind of what I was expecting. Too bad they don't fold 90 degrees to form a little bump.

    The mirrors don't fold in all that far and they present a flat frontal area when folded, so I wouldn't expect any significant change.

    I have less noise with my mirrors folded in.

    I've done some testing on this and couldn't see a change in energy consumption. I'd agree with others that the benefit gained by having less frontal area exposed to the slipstream is offset by a less aerodynamic shape exposed to the slipstream.

    In other words, the smaller frontal area is offset mostly by a higher coefficient of drag. It's possible that driving with mirrors folded is actually worse.
