Why do the Xiaomi YU7's 19-inch diamond wheels and 20-inch halo wheels adopt a closed design? What are the benefits?
The Xiaomi YU7's 19-inch diamond wheels adopt a low wind resistance design, reducing drag by 5 Counts, helping the Xiaomi YU7 achieve a drag coefficient as low as 0.245 and obtain excellent energy consumption performance. The 20-inch halo wheels also adopt a low wind resistance design. While ensuring excellent energy consumption, all 9 body colors can be matched with same-color wheels, making the overall vehicle coordination more harmonious.
The reason for adopting a closed design is that the spoke structure of the wheel cuts through the air when rotating, generating a large amount of turbulence and vortices. In contrast, closed rims have higher flatness and lower opening rates, resulting in lower vortices generated during rotation. Secondly, the flat surface of the closed rim helps the airflow on the side of the front bumper flow faster towards the rear of the vehicle, reducing mutual interference between external airflow and wheel cavity airflow, thereby lowering the drag coefficient. When designing the diamond wheels, openings were cleverly reserved to balance brake heat dissipation while maintaining wind resistance performance comparable to a fully closed state.
In addition to these two main low-drag wheel options, the Xiaomi YU7 offers 4 wheel choices for everyone. The 20-inch turbine wheels highlight a sporty atmosphere; the 21-inch phantom blade wheels feature sharp lines; the 21-inch petal and 21-inch plum blossom forged wheels balance lightweight and high strength, and are equipped with floating logos to highlight luxury. Everyone can choose different wheels according to their needs.
