BYD の高級ブランドである Yangwang は、最近、 U9 エンジニアリングテスト車両の最高速度 472.41 km / h を記録したことを発表しました。これは、テストトラックでの電気自動車の世界速度記録を正式に破り、 U9 は「世界最速の量産予定 EV 」となった、と読者のニードルズ · バルーン （ Needles Balloon ） が述べた。

公式声明によると、記録破りの速度は 5 つのコア技術アーキテクチャの結果です。

1.世界初の量産 1200V 超高電圧プラットフォーム ：
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.高性能モーター付き e4 プラットフォーム （ Yi Sifang ） ：
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.優れたパワー対重量比 ：
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 インテリジェントアクティブボディ制御システム：
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.国内開発の高性能タイヤ ：
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.
