That new version of the Xiaomi SU7 is a single-motor model with more weight, which could mean a larger battery pack and range.

The new Xiaomi SU7, model number BJ7000MBEVR3, has a gross weight of 2,090 kilograms, higher than the 1,980 kilograms of the single-motor version filed last year.

It continues to use lithium iron phosphate battery packs from CATL with unknown capacity information.

One possible guess is that the greater weight could mean that this new version of the SU7 comes with a larger battery pack and thus a longer range.

Last December, another regulatory filing revealed that the Xiaomi SU7's battery pack comes in two capacities -- 73.6 kWh and 101 kWh.

The 73.6-kWh battery pack weighs 579 kg, implying an energy density of around 127 Wh/kg. The Xiaomi SU7 with this battery pack has two CLTC range options of 628 km and 668 km, according to the December filing.

The 101-kWh battery pack weighs 645.8 kg, implying an energy density of around 156 Wh/kg and offers 750 km, and 800 km range options.

Xiaomi officially announced its entry into car building on March 30, 2021 and made the SU7 debut on December 28, 2023.

The company announced yesterday that it will officially launch the SU7 on March 28 and will allow customers to experience the model in select stores starting March 25.
