Xiaomi Auto (小米汽车) offers 3‑position carbon‑fiber wing for SU7 Ultra; adjustable bracket to be sold separately

What Xiaomi announced

Xiaomi Auto (小米汽车) has moved to bridge style and practicality for the SU7 Ultra by offering a carbon‑fiber rear wing with a three‑position adjustable bracket — and it will sell the bracket separately through the Xiaomi Auto app so existing owners can retrofit it. Need more downforce or longer range? The company says customers can now choose. The announcement came as part of a Q&A session reported by IT Home (IT之家), where Xiaomi answered owner questions about the new wing and other SU7 Ultra updates.

Range versus downforce — the trade‑off

It has been reported that the wing’s default setting is a 10° deflection and, under the CLTC (China Light‑Duty Vehicle Test Cycle) metric, yields an additional 24.5 km of range compared with a non‑wing configuration. In the middle position (5°) the reported CLTC uplift is 20 km and the car’s peak rear downforce is 127.1 kg; in the flat, maximum‑downforce setting the reported CLTC uplift is 13.5 km and downforce reaches 176 kg. Xiaomi warns that the in‑car “CLTC range” or “estimated range” displays will not reflect changes caused by adjusting the wing angle. Note also that the adjustable wing will not be bundled with the front air dam, so it cannot achieve the 285 kg peak downforce that the fixed (non‑adjustable) carbon‑fiber wing — which remains available and stays bound to the front air dam — can provide.

Styling, safety and product context

Xiaomi also introduced a new paint called “Twilight Rose,” a dual‑tone cold/warm pigment finish intended to show cool dusk tones in shadowed areas and vivid red sparkle in highlights; it was contrasted with the existing Radiant Magenta (璀璨洋红), a long‑running SU7 color and Xiaomi’s 15th‑anniversary shade. The company reiterated safety and convenience features: exterior voice control requires both voiceprint and a digital key for activation, and certain commands (like trunk open/close) are gated by vehicle state to reduce accidental activations. The SU7 line also carries an underbody “bullet‑proof” coating Xiaomi says improves scratch and puncture resistance; the firm noted puncture‑test prep measures for safety testing. These feature updates underscore how Chinese EV makers are layering styling, customization and perceived safety to stand out at home and abroad — even as geopolitical trade and regulatory pressures make overseas expansion more complex.
