yes I did, the HT is soft and a very comfortable, the rear looks really good. will test drive soon.

I want a sporty sedan car, like the IM5, BYD Seal, with large battery (85-100+kW). not sure I want another large SUV,

Another reason I'm interested on the IM5 is because MG is moving to CKD (Local Assembly) for the IM5/IM6, that will stabilize parts supply chain in Thailand. but the sales could also be lying to sell the cars. who knows..

I think more likely is the SL7 will be made in Thailand, as it sells a lot more than MG.

The CLA250+ is a also a great choice because not only the car, also the battery is fully assembled in Thailand. so parts should be easily available and no need to import.

anyone owns a the Hyptec HT?

The SL7 is made in Thailand (or gets credit under EV 3.0/3.5 as if it was made in Thailand)....that's why it still gets tagged with only a 2% excise tax under EV 3.0/3.5 vs a higher 10% excise tax for EVs imported into Thailand.

Now the Aion Hyptec HT is not made in Thailand...it gets tagged with a 10% excise tax.

I like the Avatr 11

It’s not particularly fast, but it’s very luxurious inside.

I created an app to analyze the raw data exported from Carscanner and the OBD2 device.

I found out a few interesting facts:

• The Atto 3 motor rejects 1,800 Watts of heat at highway speeds (120kmh), while the IM5 motor only rejects 675 Watts. This 62% reduction in heat is from the difference in voltage from 400V to 875V allowing current to half, thus (i^2 * R) copper losses are reduced to 1/4.

• My atto3 during the incident that it lost more than half of battery cooling, and temperature reached 53C, my battery internal resistance was really high causing a lot of heat release up to several kW.

• The Atto3 has quite a lot of copper losses actually, it could be because of the round wiring on the motor. instead of hairpin style of the new models like the SL7 Euro/China.

have a look at the code here: https://github.com/brfsa/atto3_telemetry/blob/master/atto3_telemetry.rb

and this is my Atto3 report from 2 incidents where the battery was 53C and 48C.

https://brfsa.github.io/atto3_telemetry/index.html

Wow impressed by your dedication to get into the details.

I've asked Gemini, based on your github measurements, what are the contributing factors of the heat generation, as there are multiple factors at play here between IM5 and Atto3:

• 800V vs 400V

• chemical "resistance" or discharge capacity C between a bigger IM5 battery 100kwh vs smaller Atto 3 of 6xkwh

• NCM vs LFP chemistry

• Internal Resistance cell - prismatic vs long blade v1 with higher IR

This is what Gemini tells me:

Factor	Heat Generation Impact	Technical Root Cause
Voltage Architecture (400V vs. 800V)	+300% (4x baseline)	Derived from $P = I^2 \times R$. Doubling the voltage halves the current ($I$) for the same power. Since heat scales with the square of the current, 400V systems generate exponentially more resistive heat.
Battery Chemistry (LFP vs. NCM)	+50% to +100%	LFP (Lithium Iron Phosphate) has a fundamentally higher Internal Resistance (IR) than NCM. This higher "molecular friction" converts more electrical energy into waste heat during discharge.
C-Rate / Capacity (65kWh vs. 100kWh)	+20% to +30%	The 65kWh pack faces a higher C-rate load to deliver the same performance. Drawing high power from a smaller buffer increases chemical stress and "voltage sag," further driving up the current demand.
Cell Form Factor (Blade vs. Prismatic)	Heat Retention	The BYD Blade's long, thin geometry and Cell-to-Pack (CTP) density create a high thermal mass. Heat trapped in the center of the pack is harder to evacuate than in the modular, spaced-out prismatic NCM design.

Yea, I hear you about wanting the "most range" like 600km "WLTP" range for you next EV buy. That's ballpark 600km WLTP was what I also really wanted "if I could get it" in an EV that I "totally liked" including the interior, exterior, technology, support, etc., and it was within my price range.

Yup, I am with you on most points, including pricing. Great research. I also have subscribed to Car reviewers in China to get a view of the new models, including the refresh on the Zeekr 7x, (which I like), but the local Zeekr dealers give me various stories on when that refresh will be available in Thailand (Rama 9 dealer says next year mid-year, Vibhavadi dealer says 2 years) so I will wait for the year end Motorshow at Impact in December to get the truth and place my order. However, I agree with you that I don't need any status and if I can spend less and get more I would be interested in the BYD SL7, and maybe the new Mazda CX-6e. And, as you say, all these midsize SUVs have about 480 km range WLTP using LFP batteries (including the Blade 2 or Geely Golden Brick. It seems the only way to get the 600+ range is with NMC battery packs (that seems to be the only way to squeeze out the kms given the weight and size restrictions.

So, by year end, I will be spoiled for choice (7x, SL7, CX-6e, even Xpeng G6), but all the standard range use the LFP around 480 km range battery packs. For the long range, they usually cost about $200k Baht more (which is fine), but it depends on whether the car makers decide to place those NMC packs into their cars for a LR version. And, yes, regarding Tesla (agree with Nazi reference by JB), but on principle, with the way Tesla dings you for everything the car ends up at 2Mil Baht, and the insurance cost is double all the others (I guess due to the aluminum body?). Anyway, I hate the idea of paying so much more for a (Chinese-made) Tesla when in most other markets (like Australia) the Tesla is only slightly more than the Chinese brand models.

For you BYD vehicle folks who may have GPack loaded on your car entertainment system so you can run apps like the full version of Google Maps vs a handicapped Google Maps version running under Android Auto/CarPlay, you may have noticed over the last month or so that you may have been logged out of GPack and when trying to log back in you couldn't complete the logon. You would get an error message on GPack along the lines of "can not connect to Google servers....try again later." But no matter how many times you tried you couldn't complete the login process and would get an error message.

Well, the problem is with the version of GPack you are running even if the BYD dealership loaded it for you probably at least months ago. Been lots of folks on BYD Facebook pages and other social media sites saying they have the same GPack login problem...if you can't login into GPack you can't run apps in Gpack.

The other day I dropped my Atto at a BYD for a service check and I also told them GPack was no longer working....couldn't logon. The dealership was aware of the problem and they said just a few days ago they got the updated GPack software to load on BYD vehicles and they would load it on mine. They did load it (it only takes a few minutes to install) and I can now log into GPack/Google/Google Maps...and the GPack update comes with a lot more apps you can download and install if desired.

Below are some snapshots from my Atto display of GPack after the dealership installed it...the updated version is 2.20260321.01 (a March 2026 version) And this version is indeed the latest version per the actual GPack website at https://www.glbas.net/

Snapshot of updated Gpack from my Atto....I circled the GPack version number which is a March 2026 version.

Before I was running a version that began with 1 and was an early 2025 version versus the latest 21 Mar 2026 version.

And a snapshot from the GPack website....it shows the latest version which matches the version my dealership loaded the other day.

And by the way I briefly watched a youtube video the other night talking the Atto 3 EVO update...you know the new Atto 3 that is going to have AWD with big motors, 800V system, and is basically a mini racecar. Well, apparently the version of entertainment system software running on it includes Google Maps running apparently without needing to have it run under GPack. Seems Google Maps may become a standard app on BYD in the near future via OTA update....no need to use Gpack to run the full version of Google Maps and run other apps....time will tell.

And yet, the arguably most 'extreme' EV at present (the BYD Yangwang U9 Xtreme) uses LFP blade batteries - seems to me the U9 has the IM5 beat. Yes, the comparison is about as wacko as comparing the Atto 3 to an IM5.

Well that is what surprises me. We are in a highly connected world (2026), and we need to see BYD to click "update" so we can run again applications on the dashboard ? We have to take back the car at BYD dealearship, after getting an appointment... As an IT, that would get on my nerves ☹️ . What can be difficult about this ?

MG ... IM5 pet friendly. Took me a while to figure out how to lock the car w/ AC on. Although to do so, car needs to be in full power mode. Means if you can get into it, you can drive it away.

For others, car full power, exit with window down, lock with button on door, then put window up.

Also no horn beep to remind you, fob is still in the car, as I did lock myself out one time, and thankfully, the other fob was available, but needed a friend to take me home, burglarize my own house to get the fob. Thankfully we weren't O&A in Nakhon Nowhere. Before asking, wife was at hospital, so couldn't simply bring me the fob.

Competition is a bitch. JP brands been ripping Thais off for decades with their overpriced crap in TH. Everything about building a car in TH is cheaper than the USA, but the same make & model, superior at that, are sold for the same or less in the USA.

USA, higher taxes, higher labor, higher utility bills, provide healthcare to workers at a cost, but sells cheaper.

Remember buying my POS Vios (Yaris) & Maxda 2, both better and sold cheaper in USA.

Imagine how nice it would be, strolling down the walkways of Krung Thep if everyone was driving BEV. You wouldn't have to breathe in, or clothes smell like exhaust afterwards. Along with nice & quiet.

China investigates EV OTA range cuts: owners say 500 km drops below 300 km

One owner interviewed by the broadcaster said his vehicle could previously charge more than 100 kWh before an OTA update, but after the update, it accepted only around 80 kWh, despite the battery health indicator still showing 95%. The owner also claimed the real-world range fell from roughly 450–480 km to below 400 km after the update.

https://carnewschina.com/2026/05/11/china-investigates-ev-ota-range-cuts-owners-say-500-km-drops-below-300-km/

I assume most EV owners disabled automatic OTA updates until they find out the details of the OTA update and that its relevant to them

I read the article you referenced and heard this story before. BYD, Tesla, Zeekr rejected this claim and BYD threatened legal action as a result, so this is probably not a concern.

Do anyone here know where I can get the full database of cars registered in Thailand per brand and model monthly?

Big Thanks!

oh man, I will be download the whole thing. :D

For those interested in how certain brands & models are actually selling by "fully completing" the selling process (i.e., finance approval, customer takes possession of vehicle, etc) below are DLT "Registration Stats for Jan, Feb, Mar and Apr 2026" for selected brands and models in the RY1 Category (Private Vehicle Max of 7 Passengers). The RY1 category that the great majority of vehicles sales fall into....pretty much what the common person drives.

Additionally, when DLT registers a vehicle the level of "Model Description" can vary depending on how the registration gets recorded in the DLT IT system and how much descriptive data the Seller provides.

Like I'm buying a BYD Sealion 7 AWD (I pick it up in a few days...window tinting being applied today). I find it interesting as to which version of the Sealion 7 people buy since there is a RWD version and an AWD version....as mentioned I'm buying the AWD version. Below shows that RWD and AWD version breakout in the BYD stats snapshot since the model description includes a good level of model details in the DLT system. I expect the level of model detail depends more on the info provided by the seller (i.e, BYD, Zeekr, MG, etc) vs DLT limiting version info recorded.

Now, just as an example, you will "not" see a lot of model details in cases like for the Zeekr 7x which has a Standard RWD model, a Long Range RWD model, and a Performance AWD model....three different models. However, no breakout of those different models exist in the below registration stats due to the minimum model description info provided/recorded. Like instead of saying say 7x Standard RWD, 7x LR RWD, or 7x Performance AWD which would allow a person to see which version people buy, instead, the models are all lumped together simply as 7x.

Anyway, below are some RY1 category registration snapshots of select brands for the Jan, Feb, Mar, Apr time frame. Gives a person a good idea of "really" how good and bad different brands and models are selling....completing the entire buy process vs just reflecting bookings/reservations that often fall to the wayside and don't result in a final buy...a person driving home in a new vehicle with red tags.

Headings are: Brand.....Model....for Jan-Feb-Mar-Apr......and running Total for Current Year

Regarding Zeekr X Compact Luxury SUV (not to be confused with the Zeekr 7x Mid-Full Size Luxury SUV) in mid March 2026 the updated Zeekr X was released in Thailand with very significant hardware improvements and also a big price reduction since Zeekr X sales had been weak.

The updated, price-reduced model was also on display at the 25 Mar-5 Apr 2026 Bangkok Motor Show. Assuming some sales of the new & improved (and price reduced) model should be appearing in April registration stats, so far it doesn't appear to be helping with Zeekr X sales. But then again maybe although the new Zeekr X became available mid March and since the car is imported maybe the bookings/sales have significantly increased but buyers are still waiting for actual delivery so the registration process can be completed. May-July registration stats should give the answer.

That's Crazy! how much value you are getting for 900K is insane. This car is a massive "market disruptor" car.

how did I miss this car? not on my list, I'm already set on the IM5 Long Range, I want that 100kWh car battery badly.

it's not 800V, but... getting 230 kW out of a 400V system is impressive!

it’s really pushing the limits of current without the voltage headroom of an 800V system.

since the pack is quite small (60kW) the X can do 10–80% in 18 minutes, which almost all 800V cars.

Surprisingly, the AWD (฿1.069M) uses older 66 kWh NMC battery, which is capped at 150 kW DC charging (30 mins for 10–80%).

The Zeekr X is same architecture as the Volvo EX30.

Not for me... but. it's a fast squirrel for the city. it's for someone looking for an agile city car that on the weekends eat the mountain curves for breakfast, I think this is insane value. 335HP RWD !

One important fact about AWD EV cars, the rear motor that does most of the work is usually a PSM (permanent Synchronous motor) and the front is a ASM (Asynchronous Induction Motor), like in the SL 7.

The Zeekr X AWS uses 2 PSM motors, which has different characteristics. It's not efficient like the SL7, but it has a high power density, it's light and small... and requires a clutch 🤦‍♂️

if you want to know more details, the SL7 is a clear winner.

Edited May 15May 15 by brfsa2

@brfsa2

Thanks for the info on the differences between a PSM and ASM.. Regardless of the brand it seemed for an AWD/two motor system the 1st/main motor was a PSM and the 2nd/secondary motor ASM.

I kept telling myself the rationale behind such a setup (i.e., different types of electric motors) was probably "cost" related but there may also be some good technical reasons behind it also. That is, it's more than just a cost thing. And sure enough a technical reason(s) exists.

More info on the differences between the previous and updated Zeekr X. And one difference which might be important to some folks is the AWD version "AC charging capability" is doubled from 11Kw to 22Kw. A lot of locations like condo buildings when installing chargers for the residents frequently install 22Kw AC chargers vs 7Kw AC chargers as a 22KW charger can be used by an EV with 7Kw, 11Kw, or 22Kw capability....creates more time slots for residents due faster charging capability, etc.

But of course to take advantage of a 22KW wall charger your EV needs to have 22KW AC onboard charging capability; otherwise your EV will just AC charge at a 7Kw rate on that 22Kw wall charger. Being able to AC charge at a 22Kw rate is definitely a lot better than at 7Kw....like 3 times as fast.

And at those charging locations along the road during road trips it's not uncommon to stop at a DC Fast Charger location which might also have one or two 22KW AC charging outlets "usually going unused" because most everyone's EV only has 7KW AC onboard charging capability and no one wants to charge that slow unless at home.

But if on a road trip with your 22KW AC charging capable EV which needs to be topped-up with electrons but all the "DC" Charger connectors are in use then being able to plug your EV into a "lonely" 22KW AC charging connector and charge at a respectable 22KW rate without queuing for the next DC charging connector could be help in reducing range anxiety/can't find an available charger/etc.

AI Overview

The updated (MY26) Zeekr X represents a significant mid-cycle refresh over the original model. While the exterior styling remains largely identical, the newer version is defined by a major interior overhaul, significantly more power, faster charging, and, crucially, a much lower and more aggressive starting price.

1. Interior & Practicality

• Center Console: The original model had a quirky floating center console. The updated model features a completely redesigned, more conventional bridge-style console that adds practical storage, dedicated cup holders, and improved door pockets.

• Boot Space: Boot volume increases from the old car’s 342 liters to 404 liters in the updated model, thanks to a larger under-floor compartment and optimizations to the rear motor layout.

• Seating & Comfort: The new model gains heated/ventilated front seats, heated rear seats, and a 50-watt ventilated wireless charger as standard across the board. The top-spec AWD version adds massage functions for the front seats.

2. Powertrain & Performance

• More Power: The updated RWD model receives a 50 kW boost to reach 250 kW, while the AWD model jumps to 365 kW (up from 315 kW).

• Quicker Acceleration: The AWD version now sprints from 0 to 100 km/h in an impressive 3.7 seconds, a slight improvement over the older version.

• Better Range & Charging: The updated RWD model switches to a 61 kWh LFP "Golden Battery," enabling faster DC charging up to 230 kW (dropping 10–80% charging times to just 18 minutes). The AWD retains its 66 kWh battery but its AC charging speed doubles to 22 kW.

3. Exterior & Features

• Colors & Wheels: The updated X introduces new colors (such as Kharki Green matte) and new 20-inch wheel options.

• Automatic Doors: Borrowed from the larger Zeekr 7X, the updated model introduces optional electric automatic doors, completely removing the physical door handles for a sleeker profile.

4. Pricing

The updated Zeekr X debuted with drastic price cuts globally (e.g., in markets like Thailand, starting under 900,000 THB), making it significantly cheaper to own than the introductory models when they originally rolled out.
