Xiaomi SU7 Ultra

Xiaomi built its name on smartphones. In February 2025 it launched the SU7 Ultra in Beijing, a four-door electric saloon aimed squarely at the fastest cars in the world. It is sold in China, and it is exactly the kind of car that finds its way to UK enthusiasts through import.

The hardware

Three motors drive all four wheels: two of Xiaomi's HyperEngine V8s units and one V6s. Xiaomi quotes 1,548 PS, 0–100 km/h in 1.98 seconds, 0–200 km/h in 5.86 seconds and a top speed of more than 350 km/h. Power comes from a 93.7 kWh CATL Qilin II battery on an 897-volt architecture, with a 10–80 per cent charge in 11 minutes. These are manufacturer figures, not VOLT-AGE test results.

Torque on demand

A tri-motor torque vectoring system adjusts motor torque 500 times a second. Track-focused cooling and brakes come as standard, along with dual-chamber air springs and adaptive dampers, and a Track Package adds more for circuit use.

The Nürburgring statement

On 1 April 2025, a production SU7 Ultra with the Track Package lapped the Nürburgring Nordschleife in 7:04.957 with Vincent Radermecker driving. It beat the Rimac Nevera's 7:05.298 by a third of a second and stood as the production EV lap record until August 2025, when the Yangwang U9 Xtreme lapped in 6:59.157. Read how the U9 Xtreme did it.

Why it matters

The SU7 Ultra shows how fast China's EV makers have moved from value cars to genuine performance machines. A company with no car history built a saloon that takes on established hypercars, and it belongs in this directory as a sign of where electric performance is heading.
