Xiaomi SU7 Ultra Prototype Spotted Testing in Germany

Xiaomi is testing a high-performance variant of the SU7 Ultra, dubbed the SU7 Ultra Extreme, which reportedly delivers 2,000 CV (metric horsepower). A prototype of the vehicle was spotted in Germany on July 16, 2026, according to reports detailing the sighting of the new electric vehicle (EV) model.

Xiaomi SU7 Ultra Extreme Performance Specifications

The SU7 Ultra Extreme represents a significant power increase over the standard SU7 Ultra. While the base Ultra model already established speed records, this extreme version targets a 2,000 CV output. This level of horsepower places the vehicle in a category of hyper-EVs designed for track performance rather than standard commuter use.

The prototype spotted in Germany indicates that Xiaomi is utilizing European roads and tracks for real-world validation. This follows a pattern of high-performance automotive testing where manufacturers use the Nürburgring and surrounding Autobahn sections to calibrate chassis dynamics and thermal management for high-output powertrics.

Comparison with the Standard SU7 Ultra

The standard SU7 Ultra was designed as a track-focused version of the SU7 sedan, featuring upgraded braking systems and enhanced aerodynamics. The Extreme variant pushes these specifications further by focusing on raw power output. According to the discovery reports, the jump to 2,000 CV is the defining characteristic that separates the Extreme from the previously announced Ultra models.

Key distinctions between the standard performance models and the Extreme prototype include:

• Power Output: The Extreme variant targets 2,000 CV, a substantial increase over the standard Ultra’s motor configuration.
• Testing Location: The use of German testing grounds suggests a focus on high-speed stability and endurance.
• Market Positioning: While the SU7 is a consumer sedan, the Ultra Extreme is positioned as a technical showcase of Xiaomi’s EV capabilities.

Xiaomi’s EV Strategy and Market Context

Xiaomi’s entry into the automotive sector began with the SU7, which aimed to compete with established players like Tesla and Porsche. By developing the Ultra and Ultra Extreme variants, the company is attempting to establish “brand halo” effects, proving that its software-integrated hardware can compete at the highest levels of automotive engineering.

The 2,000 CV figure aligns Xiaomi with a small group of global EV manufacturers, such as Rimac or Lucid, who have pushed power outputs beyond the 1,500 CV threshold. For Xiaomi, the goal is not just speed, but the integration of its “Human x Car x Home” ecosystem into a vehicle capable of extreme performance.

Industry analysts note that such high-performance prototypes often serve as laboratories. The technologies developed for the SU7 Ultra Extreme—such as advanced battery cooling and high-torque motor controllers—typically trickle down to the mass-market versions of the SU7 over subsequent production years.
