The mirror delete is worth a percent or two of fuel economy, so I haven’t quantified it (too much noise to measure the increase accurately).

Also, gphm or l/100km would be better, but it’s not common, so we don’t use it. Me may eventually display them side by side just because. Or offer different display options for different users

Wow, I never would have even thought of doing this! Can you tell us what kind of change this made in the mileage? By the way, on ecomodder.com what is the feeling about using gallons per hundred miles (GPHM) instead of miles per gallon (MPG) to measure and talk about fuel economy? (reference to GPHM: http://www.mpgillusion.com/ )

The 10 watts or so that it takes to power the screen and camera are minuscule compared to the aero benefits of eliminating the mirror.

The LCD power usage is somewhat akin to a couple of notches one way or the other on your stereo system.

How does the additional power consumption of the video equipment compare to the fuel usage necessary for pushing the mirror through the air?

Thanks for the comment. Once upon a time I had it set up this way, but I decided it would be best to add the camera in case anyone asked, even though I’m not violating any laws,

First comment!

It’s a nice mod, definitely, but I could see more use for it being the actual rear view mirror, with no passenger side mirror at all.
