Tesla Model 3, which was pointed out shortage of brake performance, succeeded in improving performance by updating the farm and receiving "Recommend"



Tesla 's popular price range EV "Model 3", which had been pointed out that the performance of the brake was poor at the Consumer Reports (Consumer Reports: CR) widely supported in the United States, improved the brake performance which was a problem I succeeded in getting the evaluation of "Recommend". This performance improvement is carried out by firmware update by OTA (via wireless), and it is also a breakthrough event that car performance improves by about 13% in about one week from the initial point of reference.

The beginning of that was the evaluation test of Model 3 conducted by CR and that the brake performance of Model 3 was found to be inferior to other cars of the same class. Model 3 is 152 feet (about 46 meters), which is the worst of existing commercial vehicles, the worst in the measurement of the braking distance (stopping distance) by the full brake from 60 mph (about 96 km / h) He was inferior to the Ford F - 150 of a huge pick - up truck with 2.5 tons as much as 7 feet (about 2 meters).

On the other hand, Tesla's publicity announced "Model 3 has an average braking distance of 133 feet (about 41 meters)." Meanwhile, CEO Eulon Mask had announced that it would improve brake performance by updating the firmware of the body to solve this problem.

In response to the firmware update performed by Tesla, CR conducted retesting of Model 3. In doing so, the braking distance (distance until stopping) by the full brake from 60 mph (about 96 km / h) was measured in the same way as in the initial test. In the previous measurement, the model 3, which recorded the worst value among current commercial vehicles with a braking distance of 152 feet (about 46 meters), was re-133 feet (about 40 meters)Record the value. The braking distance from the last record was shortened by 19 feet (about 5.8 meters), and the performance up of 12.5% ​​has been fulfilled.


According to Tesla spokeswoman, the improvement point this time makes it possible to operate properly even in various situations by reviewing the control software of ABS of Model 3. In the past, there has been no example of improving the driving performance of a car in such a short period as "software update", Jake Fisher, director of car testing at CR, said, "Over the past 19 years CR I have tested more than 1,000 vehicles, but I have never seen a car with improved driving performance using the OTA update, "he says of this incident.

Mr. Mask announced the following tweets on 22 May immediately after the problem was discovered. "It can be fixed by updating the firmware, it will be released in the next few days," he said, recalling and improving driving performance without taking large measures such as replacing parts of the car body I was clarifying the policy to make it.


And, this time, performance improvement was actually confirmed by the CR that is well-established in research ability. In the past, measures were taken to solve the problem by rewriting the control software of the body with a car dealer, but in just one week as in this case the brake performance is improved by software update It is not exaggeration to say that it was the world first. In other words, this is an epochal event that improves the performance of a real world car just like entering the adjustment of driving performance with the update of the driving game "Gran Turismo".

Meanwhile, there was no improvement in the size of the wind noise, road noise, poor ride comfort of the rear seat, etc., which was pointed out in the previous test. According to Mr. Mask, this problem is said to be countermeasures for vehicles currently in production, and it is said that it is a policy to reevaluate after receiving "vehicle lending from manufacturer" which is not normally done in CR. In addition, it is confirmed that improvements have been made in this update also about the poor usability and safety of various control functions integrated on the display of the center console part.


With the improvement of the brake performance this time, Model 3 got "brake point" brake performance, but Mr. Mask has further expressed a policy to realize the "best class level" brake performance. The CR says that the vehicle will be retested if necessary. Hopefully, I would like to expect to take measures to further improve the accuracy of the driving support function "auto pilot" along with the driving performance.
