Are the EVs efficiency universally comparable? Which model has the highest?

I’m wondering if EV efficiency like MPG is something universally comparable between different EV cars?
And if yes, which ones have the highest average efficiency?
For example, my Optiq is at 2.4/kWh on average.
——-
Edit: tons of knowledge shared and I’m glad many people involved to share their knowledge as well as real world experiences.

For instance, u/Chilidoggo [HERE] & u/Cory5413 [HERE] shared pretty good break down and link to what are the most efficient EVs in the US market and how to understand the efficiency in EVs.
——-
I’m glad some other users also shared links for Europe and Australia, too.

What’s supposed to be a combined efficiency?

New to EV world and I still haven’t fully understood MPG in an EV car!
I see some people complaining 2.4/kWh is bad or 3.5/kWh is below average. So, what is SUPPOSEDLY best MPG/kWh this car should offer for combined driving?

P.S. I hope I hear 24 MPG rather than 12 MPG eqnualivpent lol - please, don’t be pissed if you’re seeing MPG in an EV sub ;)

Pixelated MKV playback

I have a bunch of ~250MB video files on a USB drive and trying to play them on a Samsung Smart TV. The clips play just fine on a laptop using VLC.
The TV recognizes the files and the format. However, playback is pixelated, stuck and jumpy every 2-3 seconds.

Wondering if anyone has a solution to this issue.
Model: UN55NU6950
USB drive: 32FAT (32GB)

Multiple Errors and issues

A minute into driving, I saw “Service High Voltage System”, the car become light suddenly “one-pedal driving unavailable. Use the break to stop” popped! The A/C started blowing at much lower speed and warm air!
—- beside the error above and popping the high voltage system service, couldn’t find anywhere to show any details. On the app, it says everything is scanned and good —-
Really confused as what could cause, details of the error or what should I do now?

Energy Transfer

I never noticed this Energy Transfer under Charging until today. Even though, mine is not 19kw equipped model, it say its available!
It also says “Two-way charging equipment is required” not the car should be equipped but seems like another device is needed.
Does anyone have any experience with Energy Transfer or clear information of what’s that “equipment” required?

Do you get messages and other alerts from iPhone on the screen?

I have checked everything on both sides. The car has all access requires on ios. However, I don’t get any notifications regarding messages and other alerts beside the sound.
Are we supposed to get text massages & like calendar and reminders on the car screen like CarPlay or not?

Kohler quiet-close toilet seat hinge repair

Hi, the toilet seat lid have started to slam instead of slow close for a few days now. I have disassembled the hinge pieces and notice the R side rather moves more freely compare to those YouTube videos.
There’s like a gluey silicon paste to slow the movement.
Is there any trick option to repair it:
\- like add the same silicon paste; or
\- just buy the R hinge at home depot?
So without replacing the hinge kit or the whole toilet seat. I know the prices but it’s a rental and not in a place to pay and get reimbursed by the owner. Thanks

Update 661.30 - the wait is over…

Apple Music is here. Dolby surround is truly magic. The sound of each instrument and singer comes from different corner of the car 😌
The car is 2026 and Android 14 from factory, since some asked.
EDIT: the Dolby Atmos/ Spatial Audio is not available for all songs. I did only a quick test. So, I don’t know how many songs are available to play in Atmos mode.
——

This software update includes the following:
• Improvements to system responsiveness
• Improvements to camera image clarity
• Fixes to prevent blank screens and audio drop-outs
• Improvements to vehicle software update installation
• Surround Vision Recorder, a new feature that allows you to record, watch, and save via vehicle's cameras.
• Security Recording, a new feature that can automatically begin recording if your vehicle's alarm is triggered while it is parked.
• Cabin Glance, a new feature that displays a live feed of the seating area on your infotainment screen. This allows you to check on passengers, such as kids or pets.

P.s I already had the recording feature. But now the car doesn’t recognize my usb drive. I guess I need to format the thumb drive again.

What do you use this space for?

Never had a car with open space under center console before so I’m wondering what do you use it for? I put a full size tissue box in there.
Also, I wash it was covered in someway.

Reset the info. data, Gemini has taken away!

I reset the infotainment data in the hope of getting Apple Music. In an Uno move, the Gemini that I got it last week is gone instead! It looks like it’s irreversible!!!

P.s: I wasn’t going to use Gemini but how can a feature be taken away?!! Google punishing me for not being grateful for Gemini??? lol

—— should I visit the dealership and ask for a force update for Apple Music? ——

Surrounded Vision: worse than webcam :\

Just tried the Video Recorder/Surround Vision. The picture quality is 1280*768! On a sunny day, the quality is so bad that you won't be able to read the license plate number of the car behind you at a red light. 1:09 of video is 33MB! That's a 2008 file size.

Besides, in the park mode ONLY the in-vehicle camera records for 30 seconds in case of alarm goes off! And that is not available at the moment :I

I guess going back with dashcam.

Optiq feels like stuck w the old Android of never getting features

Joined everyone here, recently.
Many years ago, after a decade, I decided to switch to iPhone* why: because many exciting features that were presented during Google I/Os never delivered or forgotten and just frustrating after frustration.
Now, I am looking at Apple Music or Digital Key! Both have been introduced with much excitement and how to setup on the app or online EXCEPT, the feature doesn’t exist. And no actual release date.
I feel like anything with Android is an endless let down game.
* not trying to sparkle Apple vs google. Venting 😑

So I’m looking for some SUVs from leasehackr, probably. I still don’t know what to look at to find out the “best deal” option for a car?

People argue how each of the above has flaws and can’t represent to kinda verify this deal is a great option… please, be HONEST. Also, I’m also not looking for a broker, att.
