Car stuff on March 27, according to foreign media insideevs reports, a few days ago, a Canadian Tesla Model 3 user Gary Pandher said that he ordered an HW3.0 (HW is the abbreviation of hardware, is the name of Tesla’s self-driving computer, 3.0 is the version number) ‘s Model 3, but he recently found that his car is equipped with HW 2.5 instead of HW 3.0.
When he bought a vehicle, he chose the version equipped with HW 3.0. Before that, he always thought that his car was equipped with HW 3.0. Until recently, his friends also bought a HW 3.0 version. However, after completing the latest upgrade of the car, he found that his vehicle did not have as many functions as his friends.

HW 2.5 uses Nvidia ’s customized Drive PX2 computing platform, while HW 3.0 uses a new computing platform built by Tesla for FSD chips. The image processing speed of HW 3.0 is H21 times of W 2.5, computing power increased by about 7 times, but the energy consumption is only 1.25 times of HW 2.5, the peak power of HW 2.5 is 57W, and HW 3.0 is 72W.
HW 3.0’s performance is more powerful. Because of this, Tesla can develop more autonomous driving functions based on HW 3.0, and even Tesla’s claimed fully automatic driving function can be achieved with the help of HW 3.0.
Tesla has experienced a reduction in allocations in China before. Earlier this month, some domestic users found that the on-board environmental information list of the Tesla Model 3 they purchased was written as HW 3.0, but When the car was delivered, it was stolen and replaced with HW 2.5. Then the user exposed this on Weibo. After that, many users have been leaking news about Tesla’s reduction.
This incident also alarmed the Ministry of Industry and Information Technology. The Ministry of Industry and Information Technology had an interview with Tesla on the reduction. After that, Tesla acknowledged the mistake and promised to replace HW 3.0 for users for free.
Tesla said at the time that the reduction in China was due to the impact of the epidemic and insufficient parts, so it used HW 2.5. However, there was no epidemic last September, and vehicles promised to be delivered after April in Canada will be equipped with HW 3.0, but still use HW 2.5.
This is also the reason why users are angry. The Chinese user ’s configuration sheet clearly states that HW 3.0, and Canada also said that it will be equipped with HW 3.0 after a certain period, but it was secretly replaced with HW 2.5 during delivery. Tesla did not really do this. Too kind.
Tesla has reduced fermentation with continuous fermentation, 3 cases have appeared in Canada
Gary Pandher, a Tesla Model 3 owner in Canada, ordered a Tesla Model 3 in Ontario last September and picked it up on September 30.
One of the reasons he said he chose to buy this car in September was that he didn’t want to buy a car equipped with HW 2.5. Initially he chose a four-wheel-drive long-life version of the vehicle. After a few days, he changed to Standard endurance upgrade version of the vehicle.
When purchasing a vehicle, he asked his car consultant whether the vehicle was equipped with HW 2.5 or HW 3.0. The consultant confirmed to him that the vehicle would be equipped with HW 3.0 by mail.

Since then, Gary Pandher has been convinced that HW 3.0 was used in his vehicle, and until recently something changed.
Gary Pandher helped his friend also buy a Tesla car equipped with HW 3.0. Recently, they both updated the vehicle’s software system, but after the update, he found that his friend’s Tesla car owned Has more functions than itself.
Later, Gary Pandher realized that his vehicle should be equipped with HW 2.5 instead of HW 3.0, but when he bought the car, Tesla did not tell him that he would get a HW 2.5-equipped car.
Gary Pandher wants Tesla to replace the latest HW 3.0 for his vehicle, but he doesn’t know how to contact Tesla. Therefore, Gary Pandher broke the news to insiders outside media, insideevs has verified with Tesla Company, but Tesla has not yet responded.
But this is not the first Tesla reduction in Canada. At the beginning of this month, two Canadian Tesla users anonymously disclosed to the media that Tesla did not provide them. The latest HW 3.0, but still equipped with HW 2.5.
thisSome users have already reported the problem of reducing the allocation.
The Tesla cars of these two users were delivered after September 2019. According to a previous statement issued by Tesla, they will be equipped with HW 3.0 for cars manufactured after April 2019 free of charge.
However, these two owners have upgraded HW 3.0 after continuous communication with Tesla.
It is worth mentioning that Tesla’s downsizing incident did not just happen in Canada, and Tesla’s auto-driving hardware downsizing incident first broke out in China.
Early this month, a Tesla Model 3 user in China found that the vehicle controller model on the on-board environmental protection information list does not match the actual hardware model of the vehicle. The vehicle controller model marked on the list is HW 3.0 (Code 1462554) , but the actual hardware model of the vehicle is HW 2.5 (Code 1483112) .
Comparison map released by domestic car owners
So, he posted this problem to Weibo. After that, Tesla’s domestic Model 3 owners successively reported on Weibo, forums and other social media that the domestic Model 3 they bought had a reduction in distribution.
The increasing number of complaints has attracted the attention of the Ministry of Industry and Information Technology. On March 10, the Ministry of Industry and Information Technology interviewed Tesla about the illegal assembly of Tesla Model 3 vehicles with HW 2.5. “Remarks”> (Shanghai) Co., Ltd.
Later, Tesla acknowledged the error and stated thatThe impact of the epidemic, insufficient parts, only HW 2.5 was used, and announced that the latest HW 3.0 will be replaced free of charge for customers.
HW 3.0 image processing speed and computing power are better than HW 2.5
So, what’s the difference between the protagonist of the turbulent Tesla reduction match HW 2.5 and HW 3.0?
HW 2.5 uses the Drive PX2 computing platform customized by NVIDIA, and HW 3.0 uses a new computing platform built by Tesla for FSD chips. The image processing speed of HW 3.0 is 21 times that of HW 2.5. The computing power is increased by about 7 times, but the energy consumption is only 1.25 times that of HW 2.5, the peak power of HW 2.5 is 57W, and HW 3.0 is 72W.
Tesla FSD chip
The core component in HW 3.0 is Tesla’s self-developed FSD chip. FSD is an FPGA chip manufactured using Samsung’s 14nm FinFET process. The core area is 260 square millimeters, and 6 billion transistors and 250 million are integrated. Logic gate, 32MB SRAM cache, 96 × 96 multiply-add array.
Each chip has up to 12 ARM A72 CPU cores, clocked at 2.2GHz. In addition, there are dedicated independent security modules that only run encrypted Tesla software.
HW 3.0 has two complete FSD chips. Even if one system fails, the other system can still work. All the information will be sent to the two chips at the same time, they will process and make decisions separately, and then compare them. After reaching an agreement, the main system will take the next action and the system SoC will verify it.
It can be said that Tesla can putThe promise of a fully self-driving car will come from HW 3.0.
It should be noted that HW 3.0 will be used only if the user selects Tesla ’s fully automatic driving function of FSD. (optional FSD must be installed It is HW3.0) . For users who do not have the option, HW 2.5 does not affect any user experience.
But the core of the problem is that after all, Tesla promised to deliver HW3.0 hardware to users, and even the environmental protection list submitted to the government is also the HW3.0 version, and then secretly reduced the user ’s allocation in Canada and China. , This is really not the style of this electric car boss.
Conclusion: Tesla’s “Little Smart” is hurting himself
Tesla is the most successful electric car company in 2019. Electric car sales lead other car companies. Cumulative sales also became the world’s number one last year. From all aspects, it is currently the best electric car. the company.
But this year, Tesla ’s reduction in China ’s distribution has caused a significant impact on its brand. First, car owners jointly complained, and then Tesla was also interviewed by the Ministry of Industry and Information Technology. It may even be on the 315 party. (315 nights will be delayed due to epidemic reasons) .
Now the same problem is happening in Canada. Tesla’s “little cleverness” is seriously hurting its brand power. Now it is during the epidemic that the continuous negative news will make Tesla’s situation even more serious. difficult. ♪
