比亚迪旗下豪华品牌洋旺宣布其U9工程测试车最近最高时速达到472.41公里/小时，汽车界一片喧嚣。正如我们的读者Needles Balloon所说，这正式打破了全球电动汽车在测试赛道上的速度纪录，使U9成为“世界上最快的生产意向电动汽车”。

根据官方说法，破纪录的速度是五项核心技术架构的结果。

1.全球首个量产1200V超高压平台：
A critical enabler for the Yangwang U9’s performance is its utilisation of the world’s first mass-produced 1200V ultra-high voltage platform across its entire domain. Compared to conventional voltage platforms, this 1200V system enables electric motors to acquire energy more efficiently during operation, thereby delivering a more powerful and stable output that reaches a top speed of 472.41 km/h.

2.配备高性能电机的e4平台（易四方）：
At the heart of the U9’s propulsion system is the e4 platform (Yi Sifang). This system is the world’s first four-motor platform built around 30,000 rpm high-performance electric motors. Each individual motor boasts a peak power output of 555 kW, contributing to a staggering combined system horsepower of 2977 hp (or 3019 Ps).

3.卓越的功率重量比：
These high-output motors endow the Yangwang U9 with a high power-to-weight ratio of 1217 Ps/t. This power-to-weight advantage provides the thrust and acceleration foundation essential for achieving and sustaining such speeds. For comparison, the Koenigsegg Jesko Absolut, which currently holds the world speed record, has a power-to-weight ratio of approximately 1000 Ps/t.

4. DiSus-X智能主动车身控制系统：
The advanced DiSus-X intelligent active body control system (Yun Nian-X) also played a pivotal role in the record run. By actively and precisely adjusting the vehicle’s posture, the system enhances grip performance.

5.国内开发的高性能轮胎：
The Yangwang U9 is equipped with China’s first domestically developed tires specifically designed for a maximum speed of 500 km/h. These specialised tires feature a wide tread and incorporate semi-slick technology, which collectively increase the contact patch with the ground, thereby boosting grip and ensuring optimal traction at record-setting velocities.
