Xiaomi SU7 Ultra Prototype’s Nürburgring Record: What the 6:46.874 Lap Meant

On October 28, 2024, Xiaomi EV’s SU7 Ultra Prototype completed the Nürburgring Nordschleife in 6:46.874. Xiaomi presented the run as the fastest four-door-car lap on the circuit at the time, beating the previous benchmark by nearly 11 seconds. 214

The crucial qualification is that this was a track-only, non-production prototype. It was an important engineering and publicity milestone, but it did not replace the production-car record. 612

Xiaomi’s two-phase Nürburgring plan

Xiaomi announced its Nürburgring programme in July 2024 as a two-stage challenge. The first phase used the SU7 Ultra Prototype to pursue non-production-car lap records. The second phase was intended to bring a production model back to the circuit and target production-car records in 2025. 1338

That distinction shaped the meaning of the October result. Xiaomi was not claiming that a showroom-ready SU7 Ultra had become the quickest production EV around the Nordschleife. Instead, it was using a purpose-built prototype to establish a performance benchmark and gather the experience needed for the later production-car attempt.

Why the Nordschleife was the test

The Nürburgring Nordschleife—often called the “Green Hell”—is a roughly 20.8-kilometre circuit used for demanding performance and development work. Its long lap combines high-speed sections with elevation changes, blind corners and changing surface characteristics, making it a severe test of power delivery, braking, tyres, cooling, suspension and driver confidence. 19

Xiaomi’s announcement also framed the attempt as part of a broader effort to establish itself in high-performance electric vehicles. The company said it wanted to become the fastest four-door electric car at the Nürburgring within ten years, with the prototype serving as the first step toward that longer-term goal. 38

How Xiaomi prepared for the record attempt

The Nürburgring work was not limited to a single timed lap. Xiaomi’s R&D team carried out circuit surveying, tyre preparation, setup work and debugging before the official attempt. Reports said the team used the testing programme to refine the car and develop operational knowledge of the circuit. 48

The timing window on October 28 was limited. After final inspection and preparation, the prototype entered the track late in the one-hour session and completed the recorded lap at 6:46.874. Nürburgring officials confirmed the time later that evening. 4814

Racing driver David Pittard drove the lap. He had won the Nürburgring 24 Hours, giving Xiaomi an experienced driver for a circuit where precision and familiarity matter as much as outright power. 1314

The prototype’s electric powertrain

The SU7 Ultra Prototype used a tri-motor, all-wheel-drive layout built around two Xiaomi-developed HyperEngine V8s motors and one V6s motor. Xiaomi rated the system at 1,548 PS, quoted 0–100 km/h in 1.97 seconds, and gave the prototype a top speed above 350 km/h. 26

The three-motor arrangement was intended to provide very high total output while enabling rapid control of torque across the driven wheels. In a high-speed circuit car, that control can help balance acceleration, traction and stability as the car enters and exits corners.

The prototype also used chassis torque-vectoring control. Rather than delivering identical drive force everywhere, such a system can apportion torque between wheels or axles to influence turn-in, traction and corner-exit behaviour. The aerodynamic package was designed to generate the downforce needed to use the available power through the Nordschleife’s fast sections. 612

Why the prototype and production records must be separated

The record-setting car was not simply a standard SU7 Ultra with more power. Reports described it as a stripped-out, lightweight prototype with a carbon-fibre body and track-focused equipment. Those changes gave it advantages over a customer production sedan, particularly in weight, aerodynamic performance and circuit setup. 6

That is why comparisons with production cars require care. The prototype’s 6:46.874 was a four-door benchmark, but it was not an apples-to-apples production-EV result; vehicles in different Nürburgring record categories are not directly interchangeable. 612

What happened in the second phase

Xiaomi later reported that the production SU7 Ultra completed a Nürburgring lap in 7:04.957 in June 2025, describing it as the fastest electric executive vehicle record. 20

The production car’s slower time than the prototype was not a failure. It illustrated the performance gap between a purpose-built track prototype and a road-going model that must retain production equipment and usability. Together, the two runs show the logic of Xiaomi’s original plan: use the prototype to push the engineering envelope, then validate what can be transferred to a production vehicle.
