There was a Swedish car magazine that tested the AWD system in the Seal by placing some rollers in the rear wheels and found out it was not really an AWD car because it would get stuck and not activate the front wheels to advance. They communicated their findings to BYD and BYD issued a quick software update. Probably that's why now it's AWD all the time, even when not needed. They're probably try to figure out how to make a good software that works well for every scenario. So in a way, it's good news that it's probably a software issue that can be fixed with some update.

[@hummerltheOh]

If they really put out a SW-change that caused the car to be AWD all the time i wonder if they had to re-run the certification tests. Because I doubt that such a change would not affect the rated range.

[@SomeoneAbstruse]

​@@hummerltheOh From what I gathered from those swedish tests it was mainly reverse that had the issue of not being awd (correct me if wrong) But curious that it runs 4wd instead now. They should update range and consumption estimates, or get the hammer during all range tests

[@hummerltheOh]

@@SomeoneAbstruse At least in my company we have to provide proof for all SW changes post certification that they have no impact on range

[@Alberto-mq7gw]

The tests were not for reverse. I saw the videos. They can be found online. That said, I don't know if that software update is the culprit for the relatively high consumption or not. I just think it's a plausible explanation. I don't know if there's legislation in place regarding sw updates, but I think that many manufacturers are pushing updates that can impact important things, including security. BYD itself has released updates to make the driving assistances less intrusive, after admitting that they had to first make them like that in order to get 5 stars rating on Euroncap tests. So I don't think that an update that impacts the consumption is too big of a deal compared to the other ones.

I understand that if the temperature was above 20 degrees, the result would be better, I am very disappointed with the high consumption

[@SamiPaju]

I drove the BYD Seal in April and had the same issue with autosteer. It would suddenly disengage without a warning. Even when the weather was clear, there was no debris on the road and the lane markings had been recently painted. Very unnerving.

[@londonwestman1]

This is a bit of a shame.. I liked this car but that penalty for the 4wd not be optimised yet - one way or another - is big. It's using a third more energy than the equivalent Model 3 at the lower speed (and 20% more at the high speed). And I think 4wd is just about essential as we have a dodgy farm track to think about.

[@davidolsson]

I have the awd seal. It’s alot lower and the awd can be turned off by using eco + ITAC off :) lowest is 11 during long trip.

You need to try the Seal Premium. It has a big battery and is rear wheel drive only. Much more efficient.

I have the RWD version, in the summer in 20C @ 110 kmh I get around 17kwh/100 km. In the winter with 5C, wind and rain I get around 19 kwh/100 km. Lane centering is great when it works but tends to follow the exit line which then needs manual correction.

[@rubenrios113]

Bjorn, it so nice to see that you are employing other methods to determine efficiency. this is a good method of determining long term efficiency of a vehicle. The 283 wh/km is more accurate than the cars 193 wh/km. I would enter the 283 into EvNotify to give me an actual range coupled with a ABRP to get the live data. This allowed me to see in real time the adjusted distance before turning in to charging the vehicle. What a difference it makes on a road trip here in the USA. Our chargers are far and not reliable. ABRP allows us now to rate the stations from A to F. I only go to stations that are rated A or B when on a trip. Hope your family is well.

[@davidolsson]

Yeah the audio is so much better in all around mode, night and day esp on the bass :). Been on long runs and seeing 16-18 dueing spring with th awd version. 11 if you turn off the ac 😂

[@UgglemannenFTW]

Some say it is more efficient if you remove the ITAC. You should test the difference if you got the time for it. The reason also why the car honks at you when sitting still is that the child presence detection is active.

[@mathiasknauer4464]

Bjoern, changing from the assumption of available range is always a linear range. Standard range is a higher consumption and dynamic range is only by dynamic driving style. But it does not calculate your range by your current consumption. This is a huge flaw with BYD.

[@jpataca5598]

[@davidolsson]

Yes it has a ptc. Low fan setting in the beginning to let it warm up and the scoop on the heat. There’s also a economy setting in the AC settings page. Don’t know if it was on or in normal??

Wow, BYD software appears WAY behind. I didn't expect it to be so poor. They really need to dial it in. Efficiency is awful. It is amazing to me that they are expanding markets globally so quickly with what appears to be a weak product offering. I guess for the right price it doesn't matter?

[@pieplateindustries]

In Electric vehicles there shouldn't be much range difference whether AWD is engaged or not. There is in an ICE car because there is still just one motor which in AWD mode needs to go through extra transmissions and diffs to get to all four wheels, each of which robs power. In an EV which has two separate like the BYD motors there should be no extra losses, in fact it could even be less power hungry as each motor can run at a cooler and possibly more efficient level. The AWD model will use more energy than the Single motor however because it is heavier, (almost 200kg), but switching off one motor on the AWD doesn't make that motor disappear, it is still there being lugged around and needing the same energy because the weight is still there.

[@zoomzoom9999]

AWD does not have engagements. AWD is per definition always enabled. Only 4WD goes on and off depending on conditions. AWD != 4WD

[@hg60justice]

maybe the heater is really inefficient. 🤣 my bolt euv does better in the cold than this in warmish temps. terrible efficiency.

[@ozzelot1983]

So far, what I have found out is that some articles, including those from BYD, provide incorrect information about the front motor technology. In Austria, it is stated that the front motor is a permanent magnet synchronous motor, but in reality, it is an asynchronous motor. An asynchronous motor cannot regenerate energy during braking and cannot be fully turned off, which means it continuously consumes more energy. I have decided on the AWD Seal model and hope they can optimize it for better energy consumption. I will do more research and also contact BYD Austria. They should and will have to explain why they provide incorrect product descriptions.

[@morrisg]

@ozzelot1983: You have that backwards: the asynchronous motor is an induction motor and therefore deenergizing the stator completely turns off the motor. A permanent magnet motor generates back emf when it rotates because the magnets in the rotor cannot be turned off. Go watch the latest Munro video where they analyze these two types of motor for more details.

@@Scrap-press yes I also tell the same

[@RuffyUzumakii7]

I suspect the same as for many other cars. If a Model 3 is a nearly perfect welldesigned EV (talking about cable and control unit management +) in getting the best out of a real EV built from scratch (Frunk, propeller shaft tunnel etc.), this BYD is not (yet). Perfect balance between regen and accelerating, perfect balance between heating the battery and making the best out of the used/invested energy (#octovalve), more efficient devices (Screens, performance of the AC), less cablemanagement, less control units for the same thing, heavier and less efficient motors (in combination with worse energytransfer in between all the parts and from/to the battery). Tesla has a few years of advantage and already optimized a lot. I remember when I got an update that gave me 30kms more range. Only with an OVA!
