Xiaomi shows prototype version of the SU7 Ultra

Xiaomi has unveiled the SU7 Ultra, a track-focused variant of the SU7 and its first electric car. The company hopes to set a record as the world’s fastest four-door car on the Nürburgring Nordschleife.

So far, Xiaomi has only revealed the prototype version of the SU7 Ultra, but it intends to continue development into production. The electric hypercar sports three motors, including two ‘Super Motor V8s’ units and one ‘Super Motor V6s’ unit. Lei Jun, Founder, Chairman, and CEO of Xiaomi, says the company developed the Super Motor V8s in-house and that it produces power equivalent to a V8 engine, hence the similar name.

The Super Motor V8s generates 425 kW (578 PS) and 635 Nm of torque. The Super Motor V6s states has an output of 288 kW (392 PS); the torque is not mentioned. The three motors give the SU7 Ultra a whopping 1,138 kW (1,548 PS) of total power as well as torque-vectoring and all-wheel drive capabilities.

The SU7 Ultra hits 0 to 100 kph in just 1.97 seconds and 0 to 200 kph in just 5.96 seconds, the carmaker says. The electric hypercar boasts a top speed north of 350 kph. Its friction braking system comprises thicker (+42 mm in the front and +32 mm in the rear) discs that can resist temperatures over 800ºC and AP Racing-developed six-piston callipers. The SU7 Ultra comes to a complete stop from 100 kph in just 25 metres.

Xiaomi uses a new ‘Qilin 2.0’ battery pack it jointly developed it with CATL in the SU7 Ultra. Qilin II is a racing car-oriented battery pack with 1,330 kW of maximum power output and a peak voltage of 897 V. It can supply 800 kW even at a low 20 per cent charging level. Its charging rate reaches 5.2C, which makes it suitable for racing.

The Xiaoni SU7 Ultra prototype has little in common with the standard SU7. For instance, the former’s body is made entirely of carbon. The carmaker also removed all comfort features and optimised its chassis structure with lightweight materials to convert it into the track-focused SU7 Ultra. The electric hypercar is thus more than 500 kg lighter than its older sibling, weighing just 1,900 kg. Additionally, thanks to various aero modifications like a fixed rear wing, an oversized rear diffuser, open wheel arches, and a front splitter, it generates an improved downforce of 2,145 kg.

Xiaomi aims to break the Porsche Taycan Turbo GT‘s fastest four-door car record of 7:07.55 minutes on the Nürburgring Nordschleife with the prototype version of the SU7 Ultra in October. The company plans to introduce its production version and make another attempt at the “Green Hell” (aka the Nürburgring Nordschleife) in 2025.
