Xiaomi SU7 Ultra sets lap record as fastest four-door production car at Chengdu’s Tianfu International Circuit

Shanghai (Gasgoo)- On February 11, Xiaomi Group's Chairman Lei Jun announced that the Xiaomi SU7 Ultra model set a lap time of 1:26.741 at the Tianfu International Circuit in Chengdu city, making it the fastest four-door production car ever performing on the track.

Xiaomi EV has confirmed that the SU7 Ultra will undergo lap time tests at various racetracks across China.

The Xiaomi SU7 Ultra is set to hit the market later this month, with an annual sales target of 10,000 units. The model's previously announced pre-sale price stands at 814,900 yuan. Notably, the test vehicle used for the lap time featured vented front hood openings, which may be offered as an optional feature in the production model.

Visually, the Xiaomi SU7 Ultra sports a high-saturation yellow paint with silver racing stripes, while the lower aerodynamic components are finished in black for a sportier look. The car features a carbon-fiber roof and is equipped with LiDAR. Xiaomi EV has revealed that the model integrates 17 carbon-fiber components, and its aerodynamic package can generate up to 285kg of downforce.

From the side, the SU7 Ultra is fitted with black-finished dual five-spoke wheels, carbon-ceramic brake discs, and a six-piston front, four-piston rear brake caliper setup. It also offers an optional Bilstein EVO T1 coilover suspension with 10-stage adjustability, allowing drivers to fine-tune the suspension based on road conditions and driving preferences. The car measures 5,115mm in length, 1,970mm in width, and 1,465mm in height, with a 3,000mm wheelbase.

At the rear, the model retains a carbon-fiber spoiler, albeit smaller than that of the prototype. The rear bumper and diffuser feature a black and yellow color scheme, while a racing stripe on the trunk lid echoes the design elements at the front.

Inside, the Xiaomi SU7 Ultra follows a black and yellow performance-oriented theme, consistent with the standard SU7 but incorporating more carbon-fiber and Alcantara materials. The car has been upgraded to feature sport steering wheel and racing seats, along with an exclusive track-focused UI on the central control screen. The system runs on Xiaomi's HyperOS powered by the Qualcomm Snapdragon 8295 chip and features three simulated engine sound profiles along with a built-in Track Master function.

The model is also equipped with Xiaomi Pilot intelligent driving system, which features two Orin X smart driving chips with a total computing power of 508 TOPS.

The production version of the Xiaomi SU7 Ultra features a three-motor all-wheel-drive system, which consists of two HyperEngine V8s and a HyperEngine V6s e-motors, delivering a peak power output of 1,548 horsepower. This enables the car to achieve 0-100 km/h in 1.98 seconds, 0-200 km/h in 5.86 seconds, and 0-400m in 9.23 seconds, with top speed exceeding 350 km/h

Additionally, the car supports 5.2C ultra-fast charging, allowing it to charge from 10% to 80% of its battery capacity in just 11 minutes.
