By Tempail Xiaomi introduced the SU7 Ultra as a prototype in July. Three months later, the high-performance electric sedan made its official debut in China today, with some impressive figures to share.
With an impressive 1,500 horsepower and a sub-2-second 0-to-100 km/h acceleration time, the SU7 Ultra sets new standards in electric vehicle performance—though it comes at a premium price. Here’s a closer look at the details.
Design and Aerodynamics
The SU7 Ultra builds upon the design of the standard SU7 sedan with a focus on enhanced aerodynamics. It features sportier bumpers, a prominent rear spoiler measuring 1.56 meters wide, and a wider body compared to its counterpart.
These modifications, along with an active rear diffuser, contribute to a claimed downforce of 265 kilograms. The SU7 Ultra rides on 21-inch wheels wrapped in Pirelli P Zero 5 tires.
Inside, the SU7 Ultra offers a blend of luxury and performance-oriented touches. The seats are wrapped in Alcantara leather which extends to the steering wheel, door cards, and other interior elements. Xiaomi is also using carbon fiber for interior parts such as doorstep panels, center tunnel components, and the rearview mirror.
Powertrain and Performance
The SU7 Ultra is powered by a CATL-made Qilin 2.0 battery with a capacity of 93.7 kWh. The battery is claimed to have a maximum discharge power of 1,330 kW and supports an impressive 5.2C DC fast-charging rate for a 10-80% charge in just 11 minutes.
The battery feeds a trio of electric motors – two V8s and one V6s – that together generate 1,138 kW (1,526 hp) power and a peak torque of 1,770 Nm. The setup allows SU7 Ultra to go from 0 to 100 km/h in just 1.98 seconds, reach 200 km/h in 5.86 seconds and achieve a top speed of 350 km/h.
The SU7 Ultra also boasts a quarter-mile time of 9.23 seconds and features an Asil-D torque vectoring system for improved handling.
Braking System and Competition
Xiaomi has equipped the SU7 Ultra with the largest carbon ceramic brake discs yet seen on a production car. The front discs measure 430 mm x 40 mm, while the rear discs are slightly smaller at 410 mm x 32 mm.
These brakes are designed to withstand extreme temperatures of over 1,300°C (2,372°F) and are paired with Akebono calipers (six-piston front, four-piston rear) for exceptional stopping power. Impressively, the SU7 Ultra can brake from 100 km/h to a complete stop in just 30.8 meters.
While the SU7 Ultra Prototype achieved a record-breaking lap time at the Nürburgring Nordschleife, the production version is expected to be slightly slower due to its increased weight. The prototype utilized a carbon fiber body which resulted in a curb weight of 1,900 kg.
Price and Availability
The Xiaomi SU7 Ultra carries a hefty price tag of 814,900 yuan (approximately 114,200 USD) in China. While pre-orders are already open, volume production and deliveries are not expected to begin until March 2025.
Xiaomi CEO Lei Jun positioned the SU7 Ultra as a compelling alternative to the Porsche Taycan Turbo GT, as it offers more power at a lower price point. The Porsche Taycan Turbo GT is priced at 1,998,000 yuan in China.
Goldman Sachs projects that SU7 Ultra will reach 4,000 units in sales by 2025. The vehicle already seems to be a success in China as 3,680 reservations have already been made within 10 minutes after the launch event had ended.
