What is the difference between the newly introduced 3-position adjustable carbon fiber rear wing for the SU7 Ultra and the previous one?

Official answer

We found that some SU7 Ultra users really like the styling of the carbon fiber rear wing, but mainly use the car for daily commuting. On the one hand, they do not need the downforce provided by the rear wing; on the other hand, they need a longer range more. Therefore, we specially developed a carbon fiber rear wing equipped with a bracket and 3 adjustable angles for users to choose from (adjusting the gear position requires professional tools);

In the default state, the rear wing angle is deflected by 10°. Based on the carbon fiber rear wing, the actual CLTC range increases by 24.5km, providing the longest range and the minimum downforce, which is suitable for daily driving;

In the middle gear, the rear wing angle is deflected by 5°. Based on the carbon fiber rear wing, the actual CLTC range increases by 20km, and the maximum downforce of the whole vehicle is 127.1kg;

In the maximum gear, the rear wing angle is not deflected. Based on the carbon fiber rear wing, the actual CLTC range increases by 13.5km, and the maximum downforce of the whole vehicle is 176kg, providing the maximum downforce and the shortest range, which is suitable for sports/track driving;

It should be noted that the change in range caused by adjusting the deflection angle of the rear wing will not be reflected in the "CLTC Range" or "Estimated Range" on the infotainment system. Therefore, during daily use, you may not be able to directly see the changes brought by different rear wing deflection angles from the displayed range numbers. In addition, selecting the carbon fiber rear wing (3-position adjustable) will not be paired with the front air dam, so it cannot achieve the maximum vehicle downforce of 285kg; if you need maximized downforce performance, you can choose the "carbon fiber rear wing" with a non-adjustable angle, which remains bundled with the front air dam;

Of course, we will also fully consider the needs of existing owners and will subsequently list the "3-position adjustable rear wing bracket" in the Xiaomi EV App Mall. If your SU7 Ultra is already equipped with the "carbon fiber rear wing," you can purchase the "3-position adjustable rear wing bracket" separately. After replacement, the angle adjustment function can be realized. For details, please refer to the Xiaomi EV App.
