In Lei Jun's fifth annual speech,Xiaomi SU7 Ultra Prototype made its debut. Its parameters such as "full carbon structure", "maximum downforce of 2145kg", and "maximum power of 1548PS" have excited many performance car enthusiasts. Unfortunately, Lei Jun has said that this prototype will not be put on the market for sale and will only serve track competitions.

I thought performance enthusiasts would still be eager to see the mass-produced version of Xiaomi SU7 Ultra, but I didn't expect that there is already a new "modification plan" on the market. In Xiaotong's work group, an editor shared a good thing he found on the idle trading platform MoYu. After Xiaotong opened the link, he found that it was a link to directly sell the "Xiaomi SU7 Ultra Russian version", which only costs one million and supports free shipping.

Xiaotong couldn't comment on the authenticity of the purchase link, and could only say "there are risks in purchasing". What was even more unexpected for Xiaotong was that another idle purchase link for "Xiaomi SU7 Ultra drive motor" popped up in the work group, and it only cost 27,000 yuan.

Upgrading Xiaomi SU7 to Ultra for less than 30,000 yuan does seem to be worth it, and has even attracted 4 users who "want it".Xiaotong checked and found that in addition to the drive motors for the Ultra and standard Xiaomi SU7, the on-board charger, air conditioning compressor, brake caliper and other parts are also on sale. Could this be the cost-effective way for users of the standard Xiaomi SU7 to become owners of the performance version?

Second-hand platforms become a "parts library" for car upgrades

Since even new cars like Xiaomi SU7, which has only been on the market for about half a year, have related hardware for sale, other models will most likely have similar parts for sale. Xiaotong searched high and low and excluding some idle parts that were sold due to damage, it still found quite a few "good things" for new energy vehicles.

If we only look at the drive motor, except for Xiaomi SU7,Lantu Dreamer/LANTU FREEThere are many drive motors for sale, but the price range is very "outrageous". A simple search on Xiaotong found that the prices of these parts range from 89 yuan to 100,000 yuan, while 2,000 yuan to just over 10,000 yuan is relatively reasonable and is also a relatively common pricing range.

After checking, Xiaotong found that the drive motors priced under 100 yuan are actually parts merchants who attract user inquiries by offering low prices. The product introductions of these low-priced drive motors also include introductions to various accessories and disassembled car parts, and they even state that they can provide wholesale accessories for models of different brands.

The drive motors priced at more than 2,000 yuan are idle, and there are no other obvious "routines".Zeekr、BYDKey components such as motor assemblies, differential assemblies, controllers, etc. from related brands can all be found on the MoYu platform.

Key components like these will be more expensive in traditional 4S after-sales service. Some netizens revealed that the drive motors used in mainstream new energy vehicles cost about 15,000 to 30,000 yuan (please consult the car repair service provider for specific prices).

In contrast, the drive motors on a certain fish platform are indeed very cheap. Although these parts play a critical role, the temptation of high cost performance still works - on the seller pages of these specialized accessories, many key parts have been sold.

The users who purchase these parts may replace the original parts with quality problems with low-cost methods, or they may modify them themselves.For example, users of single-motor vehicles can buy an extra motor, thereby achieving the "speed and passion" of dual motors or even more motors at a low cost.

This is not Xiaotong's random guess. According to a report by Fast Technology, aHonda FitThe owner made extensive modifications to the vehicle, not only installing a speed brake and a rear wing, but also installing a 100kW drive motor directly under the vehicle, turning the Fit from a fuel vehicle into a hybrid vehicle. In the end, the modified vehicle was seized by the traffic police.

Modified cars must meet modification requirements and pass annual inspections. In addition, according to relevant regulations, there is basically no room for modification of the engine, especially the drive motor. In this case, why do these merchants still sell these accessories or dismantled car parts? Is it to attract attention or just to meet user needs?

Now is not the time to convert to a pure electric car

As the modification culture gradually becomes popular, there are indeed many products with very unique styles on the road. In addition to modifying the appearance and posture, some car owners try to affect the power output of the engine by flashing the ECU and modifying the intake and exhaust systems in order to truly improve the power of the whole vehicle.

Entering the era of electrification, "whether pure electric vehicles can be modified" has caused heated discussions. Xiaotong believes that the core components of pure electric vehicles should not be modified for the time being. You know, the internal structure of traditional fuel vehicles has been studied more thoroughly, and the policy on the modification of traditional fuel vehicles is gradually loosening, while the modification of core components of new energy vehicles still needs further clarification and improvement of regulations and standards.

More importantly, the technology of pure electric vehicles is not mature enough, and privately modifying electric vehicles poses great safety risks.Taking the basic structure of electric vehicles as an example, pure electric vehicles are composed of high-voltage vehicle equipment and low-voltage electrical equipment, which puts very demanding requirements on the design and technology of the entire circuit. Moreover, the mainstream pure electric vehicles now also integrate intelligent and networked designs. For models like Xiaomi SU7, which already have a high level of intelligence, unauthorized modification can easily cause circuit failures, not to mention the need to install core components such as drive motors.

Furthermore, if core components such as drive motors and batteries are modified without permission, once a failure occurs, there is basically no need to consider insurance claims and after-sales warranty.

In short, it is not yet possible to modify pure electric vehicles privately. The reason why key components are "key" is that they play an extremely important role in the entire driving process of the vehicle and are directly related to the life safety of the people in the vehicle.The key components purchased from idle platforms are quite cheap, but after all, “you get what you pay for”, and perhaps only the sellers dare to guarantee that there are no problems with these components.

Modification is risky, so be careful when entering the pit

Judging from the number of buyers on the idle platform, most car owners are relatively rational and will not deliberately change the original design and related parameters of the car body. Of course, there are still many car fans who are keen on modification culture and are willing to spend time and energy to modify the car to their favorite look.

The modification culture in the domestic market has gone through several stages of development and started relatively late. However, taking into account both safety and the development of modification culture, relevant laws and regulations have been gradually improved, and car modification and related competitions have gradually received support.

There is nothing wrong with the modification culture itself, but the ones who are wrong are those who do not have a high enough safety awareness of the modification culture. From the above-mentioned modified Honda Fit case, the owner does have his own "experience" in vehicle modification. If it is exhibited at a modified car show, Xiaotong believes that this will be a modified car that attracts many car fans. However, the owner chose to drive the modified car that could not pass the annual inspection directly, which is undoubtedly irresponsible to social safety.

Perhaps you would think that dealers who provide accessories and dismantled car parts are the catalysts that promote the frequent occurrence of such illegal phenomena, but in Xiaotong's opinion, the development of domestic modification culture is inseparable from the gradual prosperity of social modification factories.It is true that there are some modification dealers who operate illegally in society, but as long as the dealers disclose information and operate legally, there is nothing wrong with them. Whether the occurrence of illegal modifications can be curbed depends on whether the awareness of the modified car owners is in place.

In addition to car owners seeking out relevant dealers for modification, there are also more and more cases where OEMs and modification factories jointly develop modified cars, and OEMs directly launch official modified cars. Official modified cars not only cater to the individual needs of modified car fans, but also further guarantee the safety performance of the vehicle. This is undoubtedly one of the important ways to promote the development of modification culture.

However, at this stage, Xiaotong always recommends not to change the relevant parameters of the core components of new energy vehicles without authorization. Modifications are risky and you need to be cautious when getting involved.
