Xiaomi Reveals SU7 Ultra Prototype: Aiming for Nürburgring Record
Xiaomi has taken a bold step into the automotive world by unveiling the prototype of its first electric car, the SU7 Ultra. This track-focused variant of the SU7 aims to set a record as the world’s fastest four-door car on the Nürburgring Nordschleife.

The SU7 Ultra, currently in its prototype phase, showcases Xiaomi’s ambition to continue development towards production. This electric hypercar is equipped with three powerful motors: two ‘Super Motor V8s’ and one ‘Super Motor V6s’. According to Lei Jun, Founder, Chairman, and CEO of Xiaomi, the Super Motor V8s was developed in-house, producing power comparable to a V8 engine, hence the name.
The Super Motor V8s generates an impressive 425 kW (578 PS) and 635 Nm of torque, while the Super Motor V6s produces 288 kW (392 PS). Combined, these three motors deliver a staggering 1,138 kW (1,548 PS) of total power, along with torque-vectoring and all-wheel drive capabilities.
Xiaomi claims the SU7 Ultra can accelerate from 0 to 100 kph in just 1.97 seconds and from 0 to 200 kph in 5.96 seconds. The hypercar’s top speed exceeds 350 kph. It features a robust friction braking system with thicker discs (+42 mm in the front and +32 mm in the rear) capable of withstanding temperatures over 800ºC, coupled with six-piston calipers developed by AP Racing. The car can come to a complete stop from 100 kph in merely 25 meters.
Powering the SU7 Ultra is the new ‘Qilin 2.0’ battery pack, co-developed with CATL. This racing-oriented battery pack delivers a maximum power output of 1,330 kW and a peak voltage of 897 V, maintaining an 800 kW supply even at 20 percent charge. Its charging rate reaches 5.2C, making it highly suitable for racing applications.
The SU7 Ultra prototype differs significantly from the standard SU7. Its body is constructed entirely of carbon fiber, and Xiaomi has removed all comfort features, optimizing the chassis with lightweight materials. As a result, the SU7 Ultra is more than 500 kg lighter than the standard model, weighing just 1,900 kg. Enhanced aerodynamics, including a fixed rear wing, an oversized rear diffuser, open wheel arches, and a front splitter, contribute to an impressive downforce of 2,145 kg.
Xiaomi has set its sights on breaking the Porsche Taycan Turbo GT’s record of 7:07.55 minutes on the Nürburgring Nordschleife with the SU7 Ultra prototype in October. The company plans to introduce the production version of the SU7 Ultra and make another attempt at the “Green Hell” in 2025.
