Xiaomi is testing a more extreme version of its SU7 Ultra at the Nürburgring, likely called the Ultra Extreme.
The sedan now sports a towering rear wing inspired by the Porsche 911 GT3 RS.

The Nürburgring rivalry between Xiaomi and Porsche has escalated.
Porsche's Taycan Turbo GT recently reclaimed the lap record with a Manthey Kit, but Xiaomi appears ready to strike back.
Aggressive Aero Overhaul
Spy shots reveal extensive aerodynamic changes. The front bumper, air intakes, and splitter are new, with fins directing air around the wheels.
Louvers on the front wheel arches and a hood similar to the original SU7 Ultra prototype complete the front.

At the rear, the twin-plane wing uses swan-neck uprights and may feature an active DRS system. A new lip spoiler and aggressive diffuser add further downforce.
It is unclear if power will increase. The current SU7 Ultra produces 1,548 hp from three electric motors.
Xiaomi previously showcased a quad-motor platform capable of 2,054 hp, which could debut in a flagship coupe or reach the SU7.

Even without a power bump, the aero improvements should significantly reduce lap times. Whether it will beat the Porsche remains to be seen.
