In the dual-motor four-wheel drive system of the Xiaomi YU7, rare earth permanent magnet materials can be called the "heart" of the drive motor. Take neodymium-iron-boron permanent magnets as an example. They have extremely high magnetic energy product and coercive force, which can enable the motor to operate efficiently while improving power density. This means that the motor can output strong power with a smaller volume and weight, endowing the Xiaomi YU7 with excellent acceleration performance and battery life. According to relevant data, the energy efficiency of new energy vehicles using rare earth permanent magnet motors can be 10%-15% higher than that of traditional motors, and the driving range can be increased by 10%-20%.

Stepping into the smart cockpit of the Xiaomi YU7, rare earths also contribute a lot. Rare earth phosphors make the display panel have bright colors and high contrast, while sensors made of rare earth compounds improve the sensitivity and reliability of the intelligent interaction system.
