Recently, Zhongbao Research Institute announced the results of the latest round of crash test in 2022, and a total of 7 models participated in the crash test, including Buick Encore S, Buick GL8 Luzun, Tesla Model Y, Toyota C-HR, Nissan New Qijun, Citroën Tianyi C5 AIRCROSS, and tank 300.
The high-profile Tesla ModelY results were released, and the three items of passenger safety in the car, the safety of pedestrians outside the car, and the safety of vehicle assistance received the highest evaluation, excellent (G), and these three were also evaluated as excellent, as well as Toyota C-HR, Tank 300, and Nissan's new X-Trail.
It should be said that the overall safety of Tesla ModelY is still very good, but unfortunately, the crash resistance and maintenance economy score is the lowest level, poor (P).
From the point of view of the secondary index score, the structural impact resistance and maintainability evaluation is general (M), indicating that it is not resistant to collision, and the accident is a larger accident; the maintenance economy evaluation is poor (P), indicating that the maintenance cost is high. This can be seen from the end of 2021, the insurance company significantly increased the Tesla ModelY premium.
Why is the Tesla ModelY not crash-resistant and the maintenance economy is poor? This starts with model Y's body-in-white structure.
Tesla began experimenting with one-piece die-cast structural parts in the Model Y model, which, in Musk's words, would be "a revolution in automotive body engineering." What is the value of the one-piece die-cast structural parts that musk is so admired?
In a word, it is cheaper to buy a car, it is safer to drive, but the cost of maintenance is high!
The traditional frame (body-in-white) is welded from hundreds of cast parts, and Tesla plans to die-cast it in one go through a large die-casting machine. At present, ModelY is only the rear bottom plate position, the parts are integrated die-casting, and the use of all-aluminum castings, the original more than 70 parts, into 2 parts, the future even converged into 1 part.
As a result, the demand for welders has been greatly reduced, production costs have been reduced, and Tesla officials expect ModelY to save 20% in production costs.
At the same time, the safety of the vehicle will also be greatly improved, and the integrated body can better absorb the impact energy in the accident.
But the side effects also come, in the past a small collision, only need to replace the hit parts, integrated body need to be replaced as a whole, this maintenance cost can not be high!
However, the biggest impact is not the ModelY owner, but the rear rear cause, because the modelY integrated molding of the rear floor is roughly the position of the fuel tank of the fuel vehicle, only the rear rear accident, it is easy to hurt here.
Finally, give all car owners a wake-up call, meet Model Y do not rear-end, the three insurance did not buy enough, really may not be able to afford!
