Xiaomi SU7 Ultra Loses The Wing For A Stealthier Nürburgring Test
The Chinese brand is trialling an updated base SU7 Ultra alongside its winged Nürburgring lap record contender
China's Xiaomi has been back at the Nürburgring honing a dramatic aero package for the SU7 Ultra sedan that it hopes will help it reclaim its production EV lap record from Porsche. But while most eyes have naturally been drawn to the huge rear spoiler on one camouflaged prototype, another Xiaomi test car without a wing has been quietly flying under the radar.
Fresh spy shots from Germany show Xiaomi isn't only testing a high downforce version of its top-spec electric sedan, but is also putting a regular SU7 Ultra without the optional track kit through its paces. It misses out on the giant fixed, motorsport-style spoiler and the aggressive rear diffuser, though it does have an active spoiler that pops up from the trunk lid above 50 mph (80 kmh) to provide downforce. We can't see any obvious changes between this SU7 Ultra prototype and the model that's already on sale, but it's possible Xiaomi is planning some changes under the skin that could make it even more powerful.
Does a 1,500+ hp sedan need more power?
The stock SU7 Ultra is hardly lacking in the firepower department. It makes a massive 1,526 (1547 PS/ 1139 kW) from a triple-motor setup that places one motor at the front axle, and two at the rear. That powertrain was a key enabler when the Ultra set the EV production car lap record at the Ring in 2025 with a time of 7:04.957, beating the Porsche Taycan Turbo, and even the Rimac Nevera hypercar, in the process.
But in 2024 Xiaomi showed a quad-motor EV platform with a silly 1,526 (1547 PS/ 1139 kW), suggesting it's hungry to push power outputs even harder. And even if the SU7 Ultra doesn't switch to a quad motor powertrain – which may be saved for an upcoming coupe – Xiaomi could find a few more horses to help it claim back its Ring crown from Porsche.
Porsche enlisted Manthey's assistance to come up with a performance package for the Taycan Turbo GT that goes above and beyond the no-back-seat Weissach kit already available on the GT. With more aggressive aero, and arch extensions covering a wider track, plus a small power boost, the Manthey Taycan ticked off a blistering 6:55.553 time in May of this year to take the Ring EV record. It still counts as a production car because the upgrade is available through Porsche dealers, Porsche owning a stake in the Nürburg-based motorsport company. But it might not be the Nürburgring production EV lap record holder for much longer, if Xiaomi gets its way.
