- Xiaomi engineered working vanes to make its aero hood functional.
- Last year, the company was sued over an aero hood that did nothing.
- The upgrade installs at a dealer and takes about two to three hours.
Xiaomi looks ready to close the chapter on the ‘fake’ aerodynamic hood controversy that rattled the company last year. The Chinese carmaker has now turned its optional carbon fiber hood into a genuinely functional component, a response that many established carmakers might study with interest.
Back in early 2025, Xiaomi began offering a special carbon fiber hood for the SU7 Ultra. The design took inspiration from the record-setting SU7 Prototype and featured two prominent air ducts that were supposed to help cool the brakes and battery. On paper, it sounded convincing. In practice, it turned out to be something else.

Soon after customers started taking delivery of SU7s equipped with the 42,000 yuan ($6,100) hood, owners discovered the promised performance benefits simply were not there. The structure beneath the hood had not been changed at all, meaning the vents were purely decorative and did nothing for cooling or aerodynamics.
Unsurprisingly, the reaction was swift. Owners pushed back, some threatened to walk away from the brand, and the situation quickly spilled into the courts.
Making The Carbon Hood Functional
Fast forward 12 months, and Xiaomi has announced it will start making these hoods functional to owners, free of charge. The company says that engineers have modified the internal structure of the front air ducts so they can work with the active grille and increase downforce over the front axle.
According to CarNewsChina, fitting the upgrade takes between 2 and 3 hours and includes the fitment of adjustable plastic vanes beneath the carbon fiber hood. It’s a big win for owners, and Xiaomi will be hoping the move helps repair some of the trust lost during the controversy.
The controversy had already reached the courts before this fix arrived. In October last year, a Chinese court sided with an SU7 Ultra owner who sued Xiaomi over the hood. The ruling required the company to refund the owner’s hood deposit, pay 126,000 yuan ($18,300) in compensation, and cover 10,000 yuan ($1,400) in legal fees. Xiaomi also promised 20,000 reward points to each customer who bought the hood, worth roughly 2,000 yuan ($290)
