Let me know what you guys think.. Ive got 77 miles on the car so its still too early to tell what sort of mpg I'll be averaging.

I should get a decent number after Thanksgiving since I'll be traveling 400miles Round trip plus 186mi for work this week...
You mean like the grille mod mugen did for the Japanese Insight?





You're average mpg is going to be lower in the Winter unless you live in a warm climate year round. Otherwise you won't see the full potential of the Insight until the Summer.

I'm thinking because the side body of the vehicle is smooth except for the door handles and mirrors...they're actually decreasing mpg because they're disturbing airflow.. Do you think that's the case?

I have the door edge guards (and body side molding) as well. I think the MPG impact is negligible... but then again I've had them on since day one and only know the fuel efficiency with them on. I've gotten at/above average MPG so far, so I think the door guards are doing okay.

The door guards may introduce a disruption to the aerodynamic flow, but I think the other aerodynamics helps on the Insight are bigger factors for MPG. - https://www.gen3insight.com/forum/25...eadlights.html

If you want to remove the door edge guards, see comments above by @Mr. Natural regarding trimming, touch up, and heat-aided removal.

I learned some aerodynamics notes in these videos that the driver side grille in 'fog lamp' / lower area is functional to cool the electric motors... so there are a few 'functional' features to parts of the front grille. And the Insight's rim design intentionally cuts thru air to direct flow behind the wheels for brake cooling.

Yea I'm really thinking of taking off these door guards. They seriously only help other vehicles and not my own from getting hit anywhere else on the doors...

Plus I'm almost certain they add wind noise to the car...if you check some model 3 owners. You'll see they're adding little pieces of foam to fill the body panel gaps which drastically reduces wind noise on the vehicle... Only problem for me is Im not sure how well black rubber/foam between the panel gaps would look on a white car.... Im worried though that any white foam is going to yellow under uv light exposure...

You can reduce wind noise by doing the following...

Lubing your door seals.

Yes! That is exactly what I'm talking about with the additional seals! I also have to fix my door alignments since the rear driver side is way off. I bet I'll have a much quieter ride once the door guards are off...

Maybe when Spring rolls around I will do the additional door seals.
