The Xiaomi SU7 Ultra is set to challenge the Taycan at the Nürburgring

The race for the title of fastest production electric car on Nürburgring is not over yet. Xiaomi can attest to that.

The Porsche Taycan helped prove that electrification doesn’t have to be an enemy of sports performance. Since then, competition has intensified as new players challenge the German brand on its own home track.

Xiaomi is one of the brands that has stood out most in this race. Its SU7 Ultra, an electric sedan with three motors, 1138 kW (1548 hp) of power, and 1770 Nm of torque, once held the record for the fastest production electric car on Nürburgring, even surpassing models like the Rimac Nevera.

Porsche responded promptly. Earlier this year, the Taycan Turbo GT equipped with a Manthey kit reclaimed the title, putting the German brand back at the top.

However, Xiaomi appears to be preparing another challenge to the current market leader. New spy photos show a prototype of the Xiaomi SU7 Ultra undergoing testing on the same circuit, with significant aerodynamic modifications.

Rear wing inspired by racing models

The rear wing, featuring two surfaces and “swan neck” type supports, resembles solutions used in models like the Porsche 911 GT3 RS. Although it cannot be confirmed solely from the images, it may even incorporate a drag reduction system (DRS), which would allow reducing aerodynamic resistance under certain conditions to boost top speed, just as in the Stuttgart concept car.

At the front, the bumper has been redesigned to include a larger splitter, along with new aerodynamic elements at the ends. There are also new openings above the front wheels and more pronounced side skirts.

3 images

The images also show the enormous carbon ceramic brake discs, although it’s not possible to determine whether any changes were made to the braking system as well.

As the prototype curves and moves away, the rear diffuser stands out, seemingly built from carbon fiber, and it will work together with the rear wing to increase downforce, helping to improve stability at higher speeds.

Electric cars up to 20,000 euros

There are already nearly 900 electric vehicles on the used market with prices up to 20,000 euros.

More power on the way?

For now, it’s still unclear whether we’re looking at a concept where the main changes are limited to aesthetic and aerodynamic aspects, or if it will also see an increase in power output.

Xiaomi has already introduced a four-electric-motor configuration with 1511 kW (2054 hp), but this has not yet made it to any production model. A more extreme version of the SU7 Ultra could thus debut this system, although there is no confirmation yet.

It remains to be seen whether the Chinese manufacturer intends to merely improve the SU7 Ultra’s performance on circuits or is preparing an even more extreme production version capable of challenging the Porsche Taycan Turbo GT again in the “Green Hell.”
