Just trying to add some perspective. No reason to get all snotty about it. ✌I guess if you don't really have anything useful to add.......
Buy more groceries.
One less trip to the grocery store will save a hundred times more than deleting mirrors.

Agree completely. That's why we need the EV1 and not the Bolt for long trips at high speeds.I disagree Jack. We can do more. Engineering a product for the masses leaves a lot on the table in the form of compromises. I've read all 84 replies in this thread and others here like it. Aero improvements make a big difference at highway speeds on long trips.
Go for it and enjoy the effort. FWIW, I've been fabricating and modifying every sort of machinery for the past sixty years. My experience says you can't polish a turd. When one begins with an upright box with a Cd of .33, impovements are picking flyshite out of the pepper. Less bad is still pretty bad. Remove the big ugly mirrors and then give me the percentage range increase at 70 MPH which has been documented. Not saying it won't be there, just saying it wouldn't be worth my time and money.Our big ugly mirrors are low hanging fruit that I'd rather not ignore. I get enjoyment out of ecomodding. For others without any fabrication or modification skills, "it's all a waste of time."
Did you read post #80 in this thread? Here, I'll paste a copy of it for you.I don’t know, I would say that he had the most useful thing to add.
Sometimes it’s better to consider the practical aspect. Mister JJ is giving you a much more useful approach to efficiency than aerodynamics.
No one is stopping you from removing your mirrors if you seriously think it will make a difference, so why don’t you just do it and report back? Anyone “providing hot air” is trying to save you time. But that’s ok, show us how wrong we are 🙂Did you read post #80 in this thread? Here, I'll paste a copy of it for you.
"Has anyone ever done a mirror delete modification on a Bolt EV? I'm not interested in the legality of it so no need to inform me about that. And yes, I've read the unhelpful replies in this long thread telling us to simply drive slower. Driving slower doesn't improve the car in any way."
As you can see, I was very specific that I was not looking for the usual unhelpful advice to slow down or drive less. I was asking if anyone actually did anything to lower the drag from their mirrors, not receive the usual do-nothing lip service that is so easy to provide electronically. Unfortunately, there are far more people providing hot air, than actual efforts and modification experience.
Oh I will indeed. Unlike you guys, I have actual hands-on experience in ecomodding and custom fabrication. I just thought there might be other talented people here as well.No one is stopping you from removing your mirrors if you seriously think it will make a difference, so why don’t you just do it and report back?

Talent or Hot Air, you decide!Oh I will indeed. Unlike you guys, I have actual hands-on experience in ecomodding and custom fabrication. I just thought there might be other talented people here as well.
You forgot covering the Bolt in a layer of clay and making golf ball dimples throughout the surfaceTalent or Hot Air, you decide!
So do you have a guess on how much payback you will get with those rear view mirrors removed from
the Box that is the Bolt?
These Mods are supposed to have a Pay Back, correct? Will you be buying replacement video rear view mirrors?
You're already driving just about the cheapest $ / mile car around. Why pinch another 20 cents per week?
I have been a penny pincher for a long time!
(All bought used except for the Metro which I got for $5300 OTD due to multiple rebates!)
'89 Base Geo Metro (58 mpg-hiwy, drove this un-airconditioned turd for 13 yrs and 240k miles!)
'01 Honda Insight (71 mpg-hiwy,, before the EPA cut ratings to make people happy)
'98 ? VW TDI (49 mpg-hiwy. running some WVO in the summer months. Good riddance.)🤭
'10 Prius ( 51 mpg, Level 5 with the Advanced Tech Package. Decent LKA, ACC and self-parking!)
The aero mods I would consider on the Bolt are:
-Aero wheel covers (baby moons, screwed on to the alloys with small drilled and tapped holes at the rim)
-Rear fender skirts. (thin clear Lexan, velcro'd in place?)
-Front tire-fender gap brush filler (like some city buses use)
-I'm not convinced about front flexible air dam and side rocker panel skirts.
-Maybe flexible tire trailing edge aero devices. (velcro'd so when they do get a hit they just pop off)
Compared to these mods, I doubt deleting the outside rear view mirrors would have a noticeable effect.
And factoring Pay Back is always part of the process.
Are video outside rear view mirrors legal? I know there is Fed talk about it.
But then, as you say, this is all Hot Air and Arm Chair engineering,,
until you get your Bolt into a wind tunnel for some accurate testing!
But that is expensive Hot Air and we should keep pay back in mind...
That is 'Plausible', they claimed.You forgot covering the Bolt in a layer of clay and making golf ball dimples throughout the surface
Sure. I dropped my drag coefficient down to a measly .23 with my mod:Are you guys going to post any photos of the aero mods you have done to your Bolt EVs, or just keep babbling on and on with no actual content?
Just babbling.Are you guys going to post any photos of the aero mods..

And 17” motorcycle tires. The rounded profile is perfect for the lowest rolling resistance!Just babbling.

The other day, I made an 8 ft. long aero tail cone for my Bolt out of balsa wood, packing tape and saran wrap the other day.
I was getting double the mi/kWh on a test drive!!
But when I got home it was gone..... probably just more trash on the side of the road somewhere.
It was beautiful!
It had a way to reach the hatch release and the whole contraption would raise with the hatch, so you didn't lose that functionality. The tail lights shone through.
Sorry, I should have taken a picture before the test drive.
Oh, and it increased the top speed to 125 mph!
It would have saved my a bundle on those expensive electrons and I only had a Buck-and-a-Half in materials!
I found a picture of my old Gen 3 Prius with that split foam pipe insulation blocking the lower grill for winter time use. It definitely lowered the Cd (I think).
I can post that,,, but,,,, you first!!
Not if someone is looking for actual aero improvements. People don't come to this thread looking for lip service counseling, on why they shouldn't bother.I don’t know, I think our contributions are just as practical as anyone else’s 😉
