On the night of May 7, Xiaomi issued a public apology in response to customer complaints about recent changes affecting its SU7 Ultra model. The company addressed concerns about the newly introduced conditions for unlocking the “Ranking Mode” feature and clarified the purpose and origin of the optional carbon fibre dual-duct hood. Corrective measures have been announced to address user dissatisfaction.

“Ranking Mode” software controversy

The company acknowledged that a recent software update imposed unlock requirements for the SU7 Ultra’s “Ranking Mode” without prior notice. The feature, intended initially as a driving performance mode, was modified without adequate communication, prompting negative feedback from users. Xiaomi has paused the software rollout and committed to issuing a revised version within four to eight weeks.

The company admitted to communication issues and stated that future updates would involve more user consultation. “We recognise that major updates impacting user experience must involve thorough dialogue with our community,” the statement read.

Carbon fibre hood and customer options

Xiaomi explained that the carbon fibre dual-duct hood was added to the SU7 Ultra after the positive reception of a prototype shown at the Nürburgring in October. Although mainly cosmetic, the hood reduces vehicle weight by 1.3 kg and improves cooling airflow to a limited extent.

Due to misunderstandings about its function, Xiaomi will allow SU7 Ultra customers to switch to the standard aluminium hood. This reconfiguration option is available for orders placed before May 10 or for delivered vehicles. These customers will also receive 20,000 yuan (2,770 USD) loyalty points. Those keeping the carbon fibre hood will still receive loyalty points. Xiaomi noted reconfigurations may slightly delay production but won’t affect other purchase terms.

The carbon fibre hood is produced using an autoclave process that takes about 12 hours per unit. Xiaomi emphasized that this component has passed safety and durability tests, including noise, vibration, and pedestrian impact protection requirements. A five-year or 100,000-kilometer warranty covers it. The company also contrasted its product with aftermarket alternatives, which may not meet similar standards.

Production vehicle testing at Nürburgring

On May 8, CEO Lei Jun confirmed that the production SU7 Ultra is currently being tested at the Nürburgring. The vehicle uses a tri-motor system producing 1548 PS, with a claimed 0–100 km/h acceleration time of 1.98 seconds and a top speed of 350 km/h. It is equipped with CATL’s Kirin II battery, which provides an estimated CLTC range of 630 km and charges from 10% to 80% in approximately 11 minutes.

Other components include Akebono braking systems, carbon ceramic discs, and a fixed carbon rear wing to increase downforce. Using carbon fibre throughout the vehicle reduces overall weight by 57 kg. The interior includes Alcantara and carbon trim, and the car comes with Xiaomi’s in-house driver assistance system.
