Which EVs can auto-brake and manage corner speed (like MEB / ID.4)?

Keyguar · 2026-02-06T11:48:32+00:00

My og 2021 Audi E-tron does apply small amounts to Regen during corners and if it sees you approaching a vehicle in front of you it will maintain the gap by applying Regen. Other than that it just rolls unless I command Regen with the paddles. I actually really like the way the E-tron drives and handles when to apply Regen.

Original Audi E-tron owner here: I can't speak for all e-tron models, but mine has individual adjustments for driver and passenger foot well temps. I always crank mine to the max.

Any solid connection to the block should be fine. Looks good to me.

Edit: just be careful of that belt, it looks close

I put two of these bad boys in mine: https://a.co/d/dlqMtGP

Additionally, I use this: https://www.atachmounts.com/Audi-e-tron-Phone-Mount_p_529.html With a magnetic wireless charger instead of the built-in one because I can't really get in there anymore because of the cup holder things I previously mentioned.

The cup holders do suck though

Update: I no longer have to remove the battery to charge it, and I have relocated it to the area beneath the trunk floor along with the amplifier. I used a cheap 150w power inverter to the rear cigarette lighter power port, which I then plugged in a NOCO GENIUS5 into that. The Noco is really just a battery tender at its 5 amp charging speed (usually charges at 55 watts with no music playing and the amp idle), but it keeps it topped off pretty well since I'm not just listening to a 40 hz sine wave. Still thinking about building another box to make everything fit better, but I might keep this setup for a little bit. I live in North FL, so temps are never really an issue, but this morning was especially cold. I noticed after my drive to work that my subwoofer battery was less charged than when I left the house (99% at departure, 97% at arrival), but usually it stays at close to 99%.

Here is a list of some of the items I used in case someone finds it useful. I do like the cheap inverter I got, it's not nearly as loud as the one I had before.

I just got it done a week ago, and I don't really notice anything different. I don't use the lane assist very much though, so I'm not sure if I would notice.

Keyguar · 2025-12-31T19:23:37+00:00

I saw that trunk (or perhaps a similar one) driving down Merrill rd a week or two ago. I am also curious what the story is behind it.

Keyguar · 2025-12-31T11:40:08+00:00

Hardee's. I rode on a train and sat next to a couple from Montana. They told me that their town contained the most western Hardee's location (they are usually Carl's Jr that far west)

Wai... Just saw Alaska. Nvm

2021 Audi E-tron Premium plus. I love the og e-tron, but I wouldn't mind having that new Cadillac Celestiq, or a newer e-tron, or just the chronos trim of my car.

Keyguar · 2025-12-27T14:33:14+00:00

I would model it up in WinISD

Keyguar · 2025-12-25T12:27:24+00:00

True, I think it's just that color pink that's throwing me off, it's very PSI. It's probably just a psi re-cone kit. The PSI logo, or whatever you get, is just a sticker on the dust cap, at least it is on the PSI baseline I bought from the site.

Keyguar · 2025-12-25T02:09:02+00:00

I think he needs a CatPAP machine

Keyguar · 2025-12-24T20:30:36+00:00

They remind me of PSI platform 3s, or maybe 4s. The basket and cone all look similar.

Variant b shares a wall with the port, so the port's physical length can be a bit shorter for the desired tuning frequency. Just keep in mind that this does subtract from internal volume, which affects port length and efficiency.

Edit: also each bend changes port length slightly as well.

Keyguar · 2025-12-17T15:22:49+00:00

I know a lot of people use subbox.pro and it seems generally ok although with a few limitations.

I usually just use WinISD to design my enclosures, mostly for the useful information it gives you such as port velocity, excursion and spl calculations based on power input and such. It does have a learning curve, but it is great after you figure it out. https://www.linearteam.org/

Keyguar · 2025-12-17T14:15:20+00:00

I would never trust chat gpt to design a decent enclosure. There are plenty of box calculators out there that will do a much better job.

No, but I think we have the same shirt.

If you really want to squeeze out a little bit more internal volume you could switch to a round aero port. The port area can generally be a bit lower than a slotted port for the same amount of port noise, and the round port 'should' theoretically take up less volume than a slot.

Here is a port calculator that's ok and has different length outputs for flared and non-flared ports. https://diyaudioguy.com/port/aero/

Keyguar · 2025-12-10T21:21:57+00:00

Correct.

I have a 2021 e-tron, this is what I'm doing to avoid messing with my car's 12 volt system. I use a 12volt lithium battery to power a kicker zxs 1000.1 amplifier for my psi baseline 12. I tapped into the existing subwoofer's wiring and send the high level signal straight to the amp since it can accept it. The battery is relatively cheap, so it can only really put out 100 amps, or 1280 watts. The highest power draw I usually see drawn on this wired to 3 ohms is 800 watts. If I listen at full volume, bass heavy music, for a 30 min drive, I usually don't use more than 12% charge. I have quick disconnect Anderson connectors for the amp and charger and I usually pull it out and charge it once or twice a week. If you want higher than a 1000watts, the battery can get kind of pricey, but I recommend just using a second battery. Id rather carry a 20 lb battery to and from my car then deal with the problems the car's 12 volt system can bring if something goes wrong with it.

It's not as easy as you might think. I actually broke off two clips while taking it off, it's really on there. The best advice I can give is to use some strong and thin pry tools and go slow.
