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.
