Details on Xiaomi EV
- mytailorisrich 3y agoAre we having an Apple vs Nokia moment in the car industry, powered by the shift to EV? In Europe it feels a bit that way.
- resolutebat 3y agoAt least European car makers are trying to stay in the race, but the Japanese appear to have just given up. Toyota is still spruiking hydrogen and others like Mazda don't even have plans to start building EVs.
- mytailorisrich 3y agoThe thing is that batteries are a big issue to produce cleanly and then to recycle. Hydrogen would be great and at the moment it is developing where batteries are not convenient.
- FirmwareBurner 3y agoI have a feeling we're gonna loose the EV race same how we lost the software race and then the mobile race. Our auto industry could be the next Nokia. Sure, I'm confident the lobbied EU leaders will put speedbumps in place for the Chinese Auto makers in the EU market, but that will do more harm than good as the local brands won't be under enough pressure to innovate, knowing the governments have their back regardless.
- akira2501 3y ago> we lost the software race and then the mobile race Was the EU ever really in the race to begin with? They really wanted to be, but you can't actually centrally plan a working software or hardware economy. > EU leaders will put speedbumps in place That's the only tool they understand how to use. It's sad that this makes them feel they have to constantly use it. > knowing the governments have their back regardless. Yea.. you almost get the feeling these policies are _designed_ to create monopolies and have nothing at all to do with fostering competition.
- ororoo 3y agoI would love to see Chinese violate patents and get away with it like apple did.
- seanmcdirmid 3y agoIn China that's just another Tuesday. I'm not sure why you don't think you are seeing it. Now, if they export such a product to Europe or the USA, that's another story.
- zihotki 3y agoAnother premium EV for a premium price. I wonder if it manages to find a spot in the market. It seems that at the moment there is a lot of premium EV supply while demand is cooling down.
- kkzz99 3y agoDoesn't really look like a cooldown cycle for me in China. The competition is extreme there. Weekly new releases with another cool state-of-the-art feature. Pure innovation going on there, which makes me, as a German, kinda worried...
- M_bara 3y agoI agree. I was there a month back and the EV adoption is incredible. From small scooters, delivery vans to sedans. EV is roaring there and from the little I saw, innovation growth is crazy. Went into a small factory for making solar street lights and it was full of solar panels and EV battery cells… note that this was a small factory with container loads of cells!
- mathverse 3y agoIt is not innovation it is evolution coming from a consumerist culture. We in Europe foolishly thought we are beyond that and here we are. Thanks german industrialists.
- ugjka 3y agoIf it is like their phones then every app and car part is going to ping back home to some servers in china
- kkzz99 3y agoThis is no different then me being a German owning an Android or Iphone, which is going to ping back home to some servers in the US.
- chaostheory 3y agoThere’s a difference between a foreign adversary and a foreign ally who’s subsidizing most of your defense.
- diggan 3y agoFor a German, both of those are both foreign adversaries and foreign allies, at the same time. One is not "better" than the other.
- chaostheory 3y agoYes, one is not better than the other until there’s a security issue in Europe that actively threatens the EU. Then miraculously Western Europeans will suddenly remember that the US is an ally. This is exactly why many US voters are growing tired of subsidizing the EU’s defense.
- beebeepka 3y agoI guess your media conveniently skips the part where joining NATO means destroying your own long range weapons. This is what they forced Bulgaria to do and they made a very big deal out of it.
- avar 3y agoI'm not American, but here you can read some extensive American reporting on it: https://nonproliferation.org/bulgaria-reaffirms-plan-to-destroy-ss-23-missiles/ https://nonproliferation.org/bulgaria-reaffirms-plan-to-dest... What you're skipping over is that the reason the US asked for their destruction is that having a NATO ally with weapons that violated the INF treaty with Russia wouldn't have been good idea.
- vincengomes 3y agoThe only standout feature of this car is that it doesn't come in the usual white or black colors.
- margalabargala 3y agoThe 500 mile range is a pretty standout feature. That beats basically anything currently on the market aside from the eyewateringly-expensive Lucid Air.
- Rebelgecko 3y agoMaybe you've already taken this into account, but CLTC ratings tend to be 20-40% higher than the way range is calculated in the US. eg a Tesla MY LR has 330 miles of range in US vs 430 miles in China, but it's basically the same car
- azinman2 3y agoAnd it doesn’t really have 330 miles of range in the US.
- margalabargala 3y agoEven adjusting for typical CLTC overestimates, the only vehicles with longer range remain are the Lucid Air and the Mercedes EQS. So even if we assume that their true range is only 75% of their claimed 800km, it will be in the top 3 longest range consumer EVs.
- tirant 3y agoI’m 100% confident that in real-life tests (see Teslabjorn YouTube Channel)it won’t beat competitors like the BMW i4 or Model 3.
- margalabargala 3y agoThat seems like an unreasonably high level of confidence to have when paired with no supporting material. A Model 3 has a battery no larger than 83kWh. A BMW i4 has a battery no larger than 84kWh. This car has a 101kWh battery. Considering the cars appear roughly approximately equally aerodynamic, it seems reasonable to expect the car with the 20% larger battery to be able to go about 20% further.
- phtrivier 3y agoSlightly off topic, but tengential : EV's range is usually measured using some sort of "mixed" cycle like WLTP where you do a bit of slow speed, a bit of high speed etc. Is there a "dumb" test that just fill up the battery, put the car on a bench, goes up to 130km/h (or whatever a sensible value for "highway speed" is), and waits for the battery to be empty ? If it's a completely stupid idea, why ?
- grecy 3y agoWind resistance is by far the biggest use of energy when moving at highway speed. Without it, you're not testing anything useful in the real world.
- mschuster91 3y agoIncrease the drag resistance on the bench appropriately, that's it.
- eightysixfour 3y agoThis is partially it, but it isn’t hard to calculate the CdA of a car and then add resistance to the rollers equivalent to the expected wind resistance, however the bigger reason is that cars operate in a dynamic environment and you don’t actually want to know how far they’d drive at 100kph with no additional wind in a straight line. It just isn’t helpful. The driving cycles have a number of issues but they purposefully try and capture more of the range of dynamics to help consumers better understand what they should actually expect from vehicles. It is like comparing CPUs only on their ability to multiply quickly vs a suite of software benchmarks.
- phtrivier 3y agoThanks, I would not have suspected drag. Still, it seems like you're saying "the number would be unrealistic", but I'm not sure people want a realistic number, just a "worst case scenario"... I understand that standard tests try to measure something "realistic", but they end up giving a value that is not what people are waiting for - which is, again, and I can't stress it enough because it's 100% of the conversation i still have about EVs with every single person I talk to - "insurance that I will be able to visit my mum on a single charge at the other end of the country". I understand it's a bad question to ask and people don't really need _that_ range, but apparently they need _that_ info :/
- j1elo 3y agoWill it show "suggested contents" in between the numbers of the speedometer?
- snakeyjake 3y agoI was told automakers have been ruining auto design and foisting gaping-nostril'd abominations on us for years due to the chinese market. Xiaomi, more Chinese than Chinese, has released one of the most beautiful, nostril-less, vehicles in years. Is every automaker stupid?
- lttlrck 3y agoIt looks like a Taycan to me, albeit with McLaren-esque headlights.
- saiya-jin 3y agoCar makers do it all the time. I have curves of our older BMW 5 series (f11) burned in my head. New VW passat came out, I saw it from up close and all subtle front and side curves are there, at same spots, done in >98% same way. These automakers are mega corporations now, not some passionate geeks working out of garages. They follow trends, curb any unique excellence in order to have uniform brand design. Chinese, they take western brands with just copy&paste, I havent seen much more. Everybosy should see Taycan in that design.
- decafninja 3y agoThere’s “taking inspiration from” and straight out copying. The line is admittedly blurry. But in this case, I kind of feel it leans a bit towards the latter. This isn’t the first instance Chinese automakers have copied designs. There have been outright shameless egregious clones of various BMWs, Porsches, etc. I don’t know what the legalities are, but those were never intended for sale outside of China IIRC.
- cpursley 3y agoThis “all the Chinese do is copy” meme needs to be put to rest. Every nation copies as first while they industrialize and learn the ropes. I’ve seen a lot more experimentation and unique designs in Chinese cars recently than European or American cars. Followed by the Koreans.

- nsteel 3y ago> Much like Volkswagen, Xiaomi already knows that car owners still prefer to have some physical buttons, Despite decades of experience in the industry, until very recently Volkswagen weirdly thought the opposite was true. It's incredible it's taken them this long to U-turn on what's been a blindly obvious problem with their current interior designs. It got the point where every other manufacturer, that did the (old) sensible thing, was praised.
- k8sToGo 3y agoVW is a very slow moving behemoth with too many cogs. That's why things take forever there.
- hristov 3y agoI am glad they went to 800V. The acceleration stat race is getting a bit stupid. But I think 800V is very important, at least for charging. It will not only let you charge fast it will let other people use the charger after you are done. I hope the industry moves both the fast chargers and the cars to 800V asap. (Naturally, fast chargers should retain 400V backward compatibility). When cars charge faster it is kind of like having more chargers.
- downrightmike 3y agoFast charging requires a lot more infrastructure and a lot more maintenance. We aren't good about maintenance, so the simpler the better.
- jitl 3y agoOnly way to git gud is to practice
- numpad0 3y agoIs EV charging actually voltage limited? I had impression that it's limited more by C rating and upstream capacity than by resistance and/or cable thickness requirements.
- nagisa 3y agoVoltage is exactly what solves the cable thickness/resistance problem.
- fuzzy2 3y agoSomewhat? This voltage isn’t (just) about the battery, but about all power connections. Cables can only take so much current after all! At 150 KW, you need 400 V × 375 A. That is an insane current figure. At 800 V, it’s just half the current. I’ve used a 300 KW DC charging station once. The cable is very thick and heavy. There are practical limits.

- croisillon 3y agothe wheels remind me of Taiwan's national flower
- chetangole 3y ago> The SU7 will have autonomous driving capabilities, too, thanks to its Xiaomi Pilot platform powered by up to two NVIDIA Drive Orin processors Interestingly, NVIDIA is making good moves in all the areas related to AI.
- janice1999 3y agoI wonder how many generations before those CPUs get replaced by a Chinese native competitor. I'm guessing the Qualcomm infotaintment processors will be replaced soon.
- eunos 3y agoWhole Chinese tech companies are adopting "Nobody got fired for using NVIDIA/QCOM" mindset. Gina is trying her hard to undo that tho.
- seanmcdirmid 3y agoHigh end semiconductors is one area where China has a lot of ground to catch up on. They can make them fast, or cheap, but can't make them fast and cheap yet. They have a similar problem with jet turbines, and most of it is related to materials engineering.
- ReptileMan 3y agoBut unlike cold war they have market based economy ... so I think that the west will be unpleasantly surprised how little we will be able to slow them down. Also - programmers have started to learn how to squeeze performance again out of the little hot rocks.
- seanmcdirmid 3y agoIt has worked for a few decades now. While almost anything else is easy to reverse engineer, the trial and error used to come up with advanced semiconductors and jet turbine engines is really hard to discern by looking at end products, and the secrets are heavily locked down in Europe and the states (even Taiwan, Japan, Korea have to import materials and equipment from a very few locked down sources for their own fabs). China will eventually get there, but they are 10s of years and billions of dollars away from it. Because of the scale of the work needed, it is also unlikely to come from private industry, and with public research a lot of that money is going to be siphoned off to corruption.
- tromp 3y agoBesides lots more pictures, carnewschina [1] also reports: > According to Xiaomi, the SU7 is a pretty aerodynamic car with a drag coefficient of only 0.195 Cd, the lowest among production vehicles. No doubt this was helped by hiring James Qiu who had previously worked on Mercedes-Benz's Vision EQXX design, a concept car with a record setting 0.17 Cd.

- toddmorey 3y agoI couldn’t get to the article or pictures due to the spin for a prize ads.
- jupp0r 3y agoI recommend ublock Origin.
- xethos 3y ago> SU7 base model is rear-wheel drive (RWD) with Xiaomi’s in-house developed V6 engine with a maximum power of 220 kW and 400 Nm torque. The statement about the V6 is throwing me. Can anyone fill me in what they're using the V6 for? I thought the SU7 was full electric, not a hybrid.
- aeyes 3y agoIt's the name of the electric motor, they also a model called V8.
- TaylorAlexander 3y agoIt's particularly annoying that they call it an engine and not a motor.
- RecycledEle 3y agoA few decades back, EVs were little econoboxes. Has anyone considered making an inexpensive, reliable, simple EV for commuters?
- bb123 3y agoYes. In Europe there is the Corsa-e and the e208. Both have >200 mile range and can be picked up less than 3 years old for under 10k.
- yurishimo 3y agoNot in NL they can't... the cheapest I can find is 18k for either model. Some of them appear to be still eligible for a subsidy, but that only brings it down to 16k. Not bad honestly considering that taxes are about to go up for EVs in the Netherlands in 2025. No more subsidization when a 30% of people own an EV!
- uxp100 3y agoThe Chevy Bolt?
- bhpm 3y agoThe Chevy Bolt EUV is to my mind the perfect little city car. It’s not really “little” by most standards but if I were buying an EV today this is the one I’d go with. I love my Teslas and will keep them for many years to come but I’m happy that Chevy has this one.
- canadianfella 3y ago[dead]
- happyopossum 3y agoThe Bolt is discontinued, and they’re using the factory to build electric trucks.
- jitl 3y agoI was in mainland China a week ago and rode in a few different domestic electric cars when taking DiDi (Uber), from BYD and others. All pretty great experiences, good build quality. A surprising percent of the cars on the street in Kunming were electric - maybe 25%. The other cards make me expect good things from the Xiaomi.
- acheong08 3y ago[flagged]
- cowthulhu 3y agoThat’s a pretty dramatic claim - do you have any citations from major/reputable news outlets or the like to back it up?
- deleted 3y ago[deleted]
- _lvbh 3y agoJust Google it. There are tons of results. https://www.wapcar.my/news/in-china-640-evs-caught-fire-in-the-first-quarter-of-2022-up-32-percent-45371 https://www.wapcar.my/news/in-china-640-evs-caught-fire-in-t... With the degree of censorship they have, I wouldn’t be surprised if more were covered up.
- cowthulhu 3y agoWapcar.my doesn’t seem very authoritative, and either way 640 cars doesn’t seem like many in a country the size of China. I asked because I did Google it, and all the top results were either unrelated, or from sites I’ve never heard of before.
- bdcravens 3y agoI'm pretty sure if you asked the average person, especially in the US, which EVs burst into flames, it'll be a US brand that they'll name.
- lgkk 3y agoLooks like a taycan

- gaoryrt 3y agoexactly
- OldManAndTheCpp 3y ago> as well as chassis stamped by its die casting machines with a clamping force of 9,100 tons — beating that of Tesla's apparently. This seems incoherent to me? Metal stamping is a process, and die casting is a separate process, from what I understand. Is there any reason to die cast a chassis? Does the press strength around the casting molds matter? I’d assume chassis parts would be built out of stamped and bent sheet metal?
- apendleton 3y agoTesla has switched their newer lines to casting. It seems like it's mostly about manufacturing efficiency rather than strength -- they can cast the whole underbody of the vehicle as a single piece rather than having dozens of stamped pieces that need to be welded or riveted together. Initially they were doing the front half as one piece and the back half as another, but they've needed to get bigger and bigger (higher- and higher-force) machines as they've gone from two-piece to single-piece construction.
- londons_explore 3y agoWhen die casting, you inject semi-molten metal into a cold mould. The mould must be held closed while metal is being injected. The "9100 tons" refers to the force keeping the mould closed. That force is approximately proportional to the surface area of the object being cast.
- bartimus 3y agoSome details about their "Super Large Die Casting Machine": https://proleantech.com/xiaomis-super-large-die-casting-technology/ https://proleantech.com/xiaomis-super-large-die-casting-tech...
- novok 3y agoAn actual HUD! The one major feature I wish teslas had, with carplay / android auto a close second.
- mikestew 3y agoWell, Teslas aren’t going to get either one anytime soon, but you could buy a Hyundai which has both features. (Granted, you’ll have to get top-level trim for the HUD). You might also find that it is a better car than a Tesla.
- maxdo 3y agoI switched from Hyundai to Tesla , and will never go back. It’s an absolute gimmick. With Hyundai even basic things work bad , like heating during winter
- ipsum2 3y agoThat's concept art. I wonder if they'll actually include it. Usually HUDs have a gray background to better reflect light.
- novok 3y agoA lot of cars have a hud option, even a toyota corrolla has it where it just reflects on the window. Helps me keep attention on the road better since it's in my line of sight. A hud would help keep the minimalist aesthetic with 'fighter jet' vibes or whatever excuse is needed for elon to say yes to it.
- sbierwagen 3y agoThe Mercedes HUD on their electric cars has some augmented reality features, highlighting where you'd supposed to turn in the outside world: https://www.youtube.com/watch?v=qp4O4AsGkZM https://www.youtube.com/watch?v=qp4O4AsGkZM
- Sytten 3y agoIt's going to be a fun time when your car is vulnerable because the manufacturer decided to stop software patches. Xiaomi isn't known for long term support, their phones get max 2-3y of updates (they release so many versions it's crazy). I am going to stay with my low tech 2013 Toyota for as long as possible that's for sure.
- justinl33 3y agowhat changes in conditions would make a previously stable car unstable? Genuinely curious. Because I'd assume software patches tend to exist solely to make incremental improvements, not fix glaring issues - if there were any I'm sure regulation would mandate that they get patched no matter how old the model.
- londons_explore 3y agoWhen someone finds a huge security hole (eg "blast this signal over high power bluetooth and you can make all Xiaomi cars within 1 mile immediately go to full throttle and crash!"). Or when a server the car uses gets shut down, and suddenly basic operations like opening the doors can't be done because it turns out the car's OS pings that server before letting any door open.
- justinl33 3y agoBut don't you think there would be larger regulatory forces in play that would protect everyone from these types of issues? Xiaomi isn't just gonna refuse in a situation like this.
- resolutebat 3y agoXiaomi is China's Apple, so what happened to the rumored Apple car? Haven't heard anything for a while, but Wikipedia claims it's still planned for 2024-25: https://en.wikipedia.org/wiki/Apple_electric_car_project https://en.wikipedia.org/wiki/Apple_electric_car_project
- wg0 3y agoThis is the only EV that might make me reconsider my EV skepticism but I think price point will stop me from doing that. And of course, repairability. How much do I have to pay for battery replacement after a decade of usage.
- clouddrover 3y agoIf you're worried about the battery then get a Nio. Nios can both charge and swap the battery. The battery can be swapped in six minutes: https://www.youtube.com/watch?v=VmWL1hZQmD0 https://www.youtube.com/watch?v=VmWL1hZQmD0 You can buy the battery outright (in which case you don't use the swap stations) or you can use a battery subscription to swap to a new battery as needed. Nio has three battery sizes: 75 kWh, 100 kWh, and soon a 150 kWh option. All in the same physical dimensions: https://carnewschina.com/2023/12/17/nio-et7-with-150-kwh-semi-solid-state-battery-achieves-a-1044-km-range/ https://carnewschina.com/2023/12/17/nio-et7-with-150-kwh-sem...
- zephrx1111 3y agoWhy Porsche? Why not Tesla?
