Xiaomi revamps its debut battery-electric saloon, the SU7
The SU7 is now available for pre-order in China, starting at 229,900 yuan, equivalent to approximately 28,200 euros. The top-tier version is priced at 309,900 yuan (nearly 40,000 euros). Depending on the variant, this represents an increase of 10,000 to 14,000 Yuan (around 1,200 to 1,700 euros) compared to previous pricing. However, it is common in China for manufacturers to set slightly higher prices during pre-order phases to ensure early customers receive the first vehicles. Prices typically stabilise during regular sales—potentially returning to previous levels for the SU7.
Customers who have already ordered the ‘old’ SU7 can switch to the updated model without additional costs until 10 January. The official market launch of the revamped Xiaomi SU7 is scheduled for April.
While the SU7 retains its existing design inside and out (with minor adjustments, of course), the changes beneath the bodywork are far more extensive, particularly in the battery and powertrain. Previously, the base version featured a 400-volt battery with LFP cells, while the Max model used an NMC battery with an 871-volt system voltage. With this update, the base battery’s voltage has increased to 752 volts, while the Max model now reaches 897 volts, according to Chinese media. This upgrade also enhances charging performance: the ‘old’ model could recharge enough power for up to 510 kilometres (CLTC) in 15 minutes, but Xiaomi claims the updated version can now achieve up to 670 kilometres in the same timeframe.
The range of all battery variants has also improved, though not as dramatically: the standard model is now rated at 720 kilometres under the Chinese test cycle (previously 700 km), the Pro version increases to 902 kilometres (previously 830 km), and the high-performance Max model achieves 835 kilometres instead of 800 kilometres. Xiaomi has not specified whether these range improvements are due to increased energy capacity, the new powertrains, or both—battery sizes have not been disclosed.
However, it is clear that all three variants now feature new motors. Previously, the models were equipped with units named V6 and V6s, inspired by the power output of V6 petrol engines. Now, all variants use the further-developed V6s Plus. In the rear-wheel-drive standard version, power has increased from 220 to 235 kW (299 to 320 hp), while the SU7 Max now delivers 507 kW (up from 495 kW), or 690 hp in the old measurement. To improve traction, the rear tyres are now 265 millimetres wide instead of 245 millimetres, while the front tyres remain at 245 millimetres. Additionally, the suspension has been upgraded: previously, only the top-tier Max model featured air suspension, but now all three variants come standard with dual-chamber air suspension and adaptive dampers.
The extension of top-tier technology to all variants is also evident in the driver assistance systems and the required hardware. Previously, Lidar sensors were only available in the Pro and Max variants, combined with an ADAS computing power of 508 TOPS. Now, all versions feature 700 TOPS of computing power for autonomous driving systems. This represents a significant upgrade, particularly for the standard model, which previously lacked Lidar and was equipped with simpler sensors and only 84 TOPS of computing power.
Xiaomi has also addressed the safety concerns initially raised about the SU7: improved brakes are now fitted across the range, the body structure has been reinforced, and the number of airbags has increased from seven to nine. Additionally, all door locks now feature a separate emergency power supply, ensuring doors can still be unlocked even if the main system fails.
It remains unclear whether and when these updates will be introduced to the closely related SUV model, the YU7. Hace sólo unos días, Xiaomi announced plans to deliver 550,000 vehicles this year—up from 410,000 units in 2025.
