With the good news that the Xiaomi SU7 Ultra prototype broke the Nürburgring Nordschleife four-door car lap record with a time of 6 minutes 46.874 seconds, the Xiaomi SU7 Ultra production car was officially unveiled on the evening of October 29. Officials said that the Xiaomi SU7 Ultra is a mass-produced high-performance car with pure racing genes, which can be used for urban commuting or directly on the track in its original factory state.
According to the information released tonight, the SU7 Ultra adopts a lightning yellow color similar to the prototype, and retains some racing parts and aerodynamic kits. First of all, the front of the car is equipped with a large front shovel and U-shaped wind blade, and the opening area of the air intake grille is also increased by 10%.
Xiaomi SU7 Ultra adopts an active diffuser with adaptive adjustment of 0°-16° at the rear of the car, and adds a large carbon fiber fixed rear wing with a wingspan of 1560mm and a chord length of 240mm. The whole aerodynamic kit can help the vehicle obtain a maximum downforce of 285kg.
In order to reduce the weight of the car body as much as possible, SU7 Ultra uses a large number of carbon fiber components, including the roof, steering wheel, front seat back panels, center console trim, door panel trim, welcome pedal, etc., a total of 17 places, with a total area of 3.74㎡.
The interior of Xiaomi SU7 Ultra also adopts the lightning yellow theme, and incorporates exclusive decorations of track stripes and embroidered badges in the details. In terms of fabric, a large area of Alcantara material is used, covering the door panels, steering wheel, seats, and instrument panel, covering an area of 5 square meters.
n terms of performance, Xiaomi SU7 Ultra adopts dual V8s + V6s three-motor all-wheel drive, with a maximum horsepower of 1548PS, 0-100 acceleration in just 1.98 seconds, 0-200km/h acceleration in 5.86 seconds, and a maximum speed of over 350km/h.
Xiaomi SU7 Ultra is equipped with the Kirin II Track Edition high-power battery pack from CATL, with a capacity of 93.7kWh, a maximum discharge rate of 16C, a maximum discharge power of 1330kW, and a 20% discharge power of 800kW, ensuring strong performance output at low power. In terms of charging, the maximum charging rate is 5.2C, the maximum charging power is 480kW, and the charging time from 10 to 80% is 11 minutes.
Xiaomi SU7 Ultra is also equipped with Akebono®️ high-performance brake calipers, with the front six-piston and rear four-piston fixed calipers having working areas of 148cm² and 93cm² respectively. The endurance racing-level ENDLESS®️ high-performance brake pads have an operating temperature of up to 1100°C, allowing the braking force to remain stable. In addition, the brake energy recovery system can also provide a maximum deceleration of 0.6g, and the maximum recovery power exceeds 400kW, which greatly reduces the burden on the braking system.
Officials said that the braking distance of Xiaomi SU7 Ultra from 100km/h to 0 is only 30.8 meters, and there will be no thermal decay after 10 consecutive brakings from 180km/h to 0.
In order to achieve better handling performance, the vehicle can also be equipped with the Bilstein EVO T1 coilover shock absorber, which can adjust the vehicle height and damping force compared to ordinary shock absorbers. The structure, stiffness and damping of this coilover shock absorber are fully customized for Xiaomi SU7 Ultra.
After being equipped with the Bilstein EVO T1 coilover shock absorber set, the spring stiffness and maximum damping force are greatly improved. The three major indicators of acceleration pitch gradient, braking pitch gradient and roll gradient are greatly reduced, thereby helping the vehicle to achieve more stable high-speed dynamic performance.
Xiaomi SU7 Ultra provides a variety of driving modes. For track laps, you can choose endurance mode, qualifying mode, drift mode, and master custom mode; for daily driving, it provides novice mode, economic mode, slippery mode, sports mode, custom mode, etc. At the same time, in order to ensure safe driving, Xiaomi SU7 Ultra needs to undergo driving ability or qualification certification when using the track mode for the first time, and the daily driving mode will impose certain restrictions on horsepower and speed.
It was also stated at the press conference that Xiaomi SU7 Ultra will also provide an exclusive track APP with functions such as reading track maps, challenging other drivers' lap times, analyzing track results, generating and sharing lap videos, etc.
Another interesting thing is that in addition to providing three types of sound waves, namely super power, super sound and super pulse, the Xiaomi SU7 Ultra also supports the function of playing the sound waves outward through an external speaker. I wonder how many riders will turn on this function. But I still urge everyone to use it in a civilized manner and not to bombard the streets.
