Xiaomi Snatches ‘Ring Glory And Unveils Road-Going 1,526 HP SU7 Ultra

Xiaomi has shattered the Nurburgring record for a four-door car with the Xiaomi SU7 Ultra Prototype and, at an event in Beijing, has also unveiled the production version of the flagship SU7. If you needed any more proof of how serious the consumer electronics giant is at tackling the fastest EVs on the planet, this is it.

adpushup.que.push(function() {
if (adpushup.config.platform !== “DESKTOP”) {
adpushup.triggerAd(“4d84e4c9-9937-4f84-82c0-c94544ee6f2a”);
} else{
adpushup.triggerAd(“6a782b01-facb-45f3-a88f-ddf1b1f97657”);
}
});

First, the ‘Ring run. Xiaomi chief executive Lei Jun hinted at the achievement on social media, revealing the EV had lapped the circuit in just 6:46.874. It’s since been confirmed that with British driver David Pittard behind the wheel – who won the 2023 24 Hours of the Nurburgring – the SU7 Ultra Prototype did indeed lay down the gauntlet with that impressive time. This makes the car more than 20 seconds quicker than the Porsche Taycan Turbo GT.

Making the time all the more impressive is that it was achieved on a single attempt. Additionally, the car lost power for roughly 10 seconds, a moment which can be seen at around 4:15 in the video. Had that not happened, it would have been even quicker.

2025 Xiaomi SU7 Ultra

At a presentation to confirm the car’s Nurburgring feat, Xiaomi also lifted the veil on the production model. It’s unclear why the road-going model wasn’t the car that tackled Green Hell, but it promises much of the same performance credentials as the prototype, although it’s not quite as extreme.

Like the prototype, the SU7 Ultra features a trio of electric motors delivering 1,526 hp. This system consists of two of Xiaomi’s flagship V8s motors and one V6s motor. It gives the car a significant power advantage over the Tesla Model S Plaid and Lucid Air Sapphire. Xiaomi says it can hit 62 mph (100 km/h) in just 1.98 seconds without a one-foot rollout, rocket to 124 mph (200 km/h) in 5.86 seconds, and power through until 217 mph (350 km/h).

Providing these motors with their juice is a CATL Qilin 2.0 battery and despite the extreme focus on performance, the car is said to have 391 miles (630 km) of range on the generous CLTC cycle. Xiaomi has extensively upgraded the cooling systems of the SU7 to make it home on a race track, improving the performance of the compressor, water pump, cooling fan, and radiator. It can reportedly complete two consecutive laps of the Nurburgring without overheating.

Brakes, suspension, aero

adpushup.que.push(function() {
if (adpushup.config.platform !== “DESKTOP”) {
adpushup.triggerAd(“e96f0476-8b1d-4bb8-b64c-33f9656987b2”);
} else {

}
});

Any four-door sedan with over 1,500 hp needs some serious brakes, and the SU7 Ultra ticks that box, too. It comes standard with carbon ceramic discs at all four corners and can stop from 62 mph in just 101 feet (30.8 m). The front discs are a massive 16.9 inches (430 mm) and are the largest carbon discs of any current production sedan. Akebono has supplied the brake calipers, consisting of six-piston units at the front and four-piston units at the rear.

The upgrades don’t stop there. Xiaomi has fitted new dual-chamber air springs and dampers, or should customers prefer, the SU7 Ultra can be equipped with Bilstein Evo T1 coilovers offering 10 levels of compression and rebound adjustment. Complex torque vectoring is also standard and can adjust power from the motors at up to 500 times per second.

Visually, you’ll notice the production-ready SU7 Ultra is not as extreme as the prototype. It lacks that car’s motorsport-spec rear wing and has a smaller spoiler. The front end is also more restrained but does stand out from lesser versions of the electric sedan thanks to a new splitter and enlarged air intakes. Other upgrades include an active rear diffuser that adjusts while driving and new skirts. The car delivers up to 285 kg (628 lbs) of downforce.

Several interior enhancements complete the package. These include a newly-designed steering wheel with a flat top and flat bottom, a 12 o-clock marker, and is wrapped in Alcantara with carbon fiber accents. The wheel also includes a bright red Boost button. Elsewhere, shoppers will find new Alcantara parts adorning the cabin, and the UI of the instrument cluster, head-up display, and infotainment display have also been customized for a sportier look. An app dubbed Racetrack Master has also been added and allows drivers to record their lap sessions and view key performance parameters on the move.

The first customer deliveries are scheduled for March 2025. Prices start at 814,900 yuan (~$114,000), and in the first 10 minutes after the car’s release, Xiaomi had received 3,680 refundable deposits.
