Will the maintenance cost for the coilover dampers of the Xiaomi SU7 Ultra be very high later on?
The Xiaomi SU7 Ultra offers an optional top-tier BILSTEIN EVO T1 coilover damper, custom-tuned by Xiaomi at the Nürburgring. While some aftermarket coilover dampers indeed require maintenance and upkeep, because the Xiaomi SU7 Ultra uses factory-installed coilover dampers, it imposes higher requirements on indicators such as durability, meaning they do not need separate maintenance and are covered by the vehicle warranty, providing peace of mind and saving money. In terms of performance, this coilover damper supports 10-stage dual-circuit damping adjustment, allowing precise adjustment of rebound and compression damping forces via a knob. Compared to air springs, this coilover damper has higher stiffness, bringing users a handling experience infinitely close to that of a racing car.
The dual-chamber closed air springs paired with high-performance continuously variable damping adjustable dampers, which are standard on the Xiaomi SU7 Ultra, can intelligently switch based on driving mode, road conditions, and body response, adjusting stiffness and height individually. This satisfies both the sporty needs of intense driving and daily comfortable commuting. Of course, these dual-chamber closed air springs also do not require separate maintenance and are covered by the vehicle warranty.
