What is the difference between the 21-inch U-shaped forged wheels on the Xiaomi SU7 Ultra and the standard wheels?
Official answer
The 21-inch U-shaped forged wheels on the Xiaomi SU7 Ultra are made from aviation-grade 6-series aluminum material using forging and milling processes. There are significant differences in both material and craftsmanship compared to the standard cast wheels, bringing many advantages:
More aesthetic styling: Due to the milling process, the 21-inch U-shaped forged wheels on the Xiaomi SU7 Ultra feature thinner spokes than the 21-inch U-shaped cast wheels, creating a unique performance-oriented visual appearance.
High strength and lightweight: The 21-inch U-shaped forged wheels maintain strength despite their slender design. Calculations show that if similar styling and strength were achieved using casting processes, the weight would be approximately 30% higher than that of forged processes.
Forged wheels have better materials and more complex processes than cast wheels, resulting in much higher costs, which is why they are offered as an optional accessory for the Xiaomi SU7 Ultra. You can choose to install the 21-inch U-shaped forged wheels individually, or opt for the upcoming "Racing Kit," which includes these 21-inch U-shaped forged wheels.
