# Xiaomi SU7

The Xiaomi SU7 (Chinese: 小米SU7; pinyin: Xiǎomǐ SU7, pronounced s-oo-tch-ee in Chinese) is a battery electric full-size sedan developed by Chinese company Xiaomi Auto, a subsidiary of the Chinese consumer electronics company Xiaomi. It is the first Xiaomi vehicle, manufactured at their plant in Beijing. The car was announced in December 2023 and officially released on 28 March 2024 in Beijing, the day Xiaomi began taking orders.
According to Xiaomi, 'SU' stands for 'Speed Ultra'. 'SU' may also be a reference to the Chinese word 速 (pinyin: sù), meaning 'speed'. The SU7 is available in four versions, namely the SU7, SU7 Pro, SU7 Max and SU7 Ultra.

## History

Xiaomi announced its intent to enter the electric vehicle market in March 2021. Xiaomi founder and CEO Lei Jun claimed the company would invest 10 billion yuan (US$1.4 billion) into the project. Xiaomi Automobile was established in 2021, based in the Beijing Economic and Technological Development Zone. The company received a permit to produce vehicles from China's National Development and Reform Commission in August 2023.
Production of the SU7 started in December 2023. It was introduced on 28 December 2023, with the first display models arriving in stores the next day, and many Xiaomi stores needing to be renovated to accommodate the vehicle. The retail price was announced on 28 March 2024; the standard version costs 215,900 yuan (US$30,408), while Pro and Max versions cost 245,900 yuan (US$34,633) and 299,900 yuan (US$42,239), respectively.

## Design

The SU7 was developed under codename MS11. The design team was led by chief designer Li Tianyuan, who was poached from BMW. According to Lei Jun, he rejected three design proposals due to durability concerns. Xiaomi benchmarked the car against the Porsche Taycan and Tesla Model S.
The sedan is equipped with air suspension with adaptive dampers, an active shutter grille, and an active rear wing with four adjustment levels on higher end models. The company claims the drag coefficient of the SU7, without the rooftop LiDAR module, is the world's lowest at 0.195. It also has a 105-litre (3.7 cu ft) frunk in addition to its 571-litre (20.2 cu ft) trunk.
The dashboard contains a 7.1-inch digital instrument cluster display, which rotates into a closed position when the car is turned off, displaying a panel with the SU7's silhouette. It also contains a 56-inch augmented-reality heads-up display reflecting off of the windshield, which is capable of displaying navigation guidance. The dashboard also has mounting points for accessories such as dashcams and phone holders. The center console has two wireless charging pads and a control panel with a start/stop button and four rocker switches for HVAC temperature and fan speed, rear spoiler controls, and suspension height adjustment. The doors feature a slot for storing a smartphone upright, and the glovebox is designed to accommodate a 14-inch laptop. The rear seats each have access to a seatback mounting point and charging port for tablets, with Apple iPads also being compatible. There is an optional 4.7-litre (0.17 cu ft) refrigerator located in the back of the center console.
The SU7 is equipped with a 16.1-inch touchscreen infotainment center with 3K resolution. The infotainment system is powered by a Qualcomm Snapdragon 8295 system-on-chip and based on the Xiaomi HyperOS (小米澎湃OS) operating system also used in devices such as smartphones, smart wearables, and smarthome devices. It allows for direct mirroring of a Xiaomi smartphones and tablets, connectivity with Xiaomi wearables like the Mi Band, and integration for Xiaomi Smarthome ecosystem devices such as the Mi Robot vacuum cleaner. Non-Xiaomi devices will also be compatible but with limited functionality, such as Apple devices with CarPlay. The display also has screw mounting points for optional accessories, including a row of physical switches for HVAC controls and a volume dial with media controls, and a set of auxiliary dial displays, both of which are configurable in the infotainment system.
It has a driver-assistance system, branded as Xiaomi Pilot, with 16 functions as standard. It uses a vision-based sensor array, and uses a single Nvidia Drive Orin X SoC with 254TOPS of computing power. Higher end models have an autonomous driving system called Xiaomi HAD, which was initially capable of supervised autonomous driving (NOA) on highways, hands-free parking, and car summoning features. Later OTA updates allowed for the use of the NOA feature in urban conditions. It uses two Nvidia Drive Orin X SoCs with a total of 508 TOPS of computing power, and a sensor suite consisting of one LiDAR, 3 mmWave radars, 11 cameras, and 12 ultrasonic sensors.
The SU7 uses many international suppliers for its parts, including Bosch, Brembo, Continental, ThyssenKrupp, ZF Friedrichshafen, Benteler, Schaeffler Group and Nexteer Automotive.

On 29 October 2024, Xiaomi unveiled the high-performance variant, the SU7 Ultra, initially priced at 814,900 yuan (114,000 USD). It was officially launched on 27 February 2025 priced significantly lower at 529,900 yuan (73,000 USD). Xiaomi aims to sell 10,000 units of the SU7 Ultra in 2025, with deliveries starting on 3 March 2025.
Xiaomi positions the SU7 Ultra as a road-legal four-door race car. The body receives significant aerodynamic changes, including 17 carbon fibre components. The front features a large front splitter with large vertical endplates, the 1.7 m$^2$ (18 sq ft) roof is fully carbon fibre saving 12 kg (26 lb) of weight, and the rear features a 1,560-millimetre (61 in) wide wing with a 240 mm (9.4 in) chord, a modified rear bumper with vents and an active diffuser, allowing for a claimed 285 kilograms (628 lb) of downforce. Other exterior changes include a 24-carat gold Xiaomi emblem at the front end and an optional painted stripe.
The interior receives a modified design and comes in three color options, with Alcantara and carbon fibre surfaces, a square-shaped sports steering wheel, and racing-style seats with additional bolstering. Carbon fibre surfaces are used on the front seatbacks, steering wheel, and doorsills, totaling 3.74 m$^2$ (40.3 sq ft), which Xiaomi says saves 12 kilograms (26 lb) of weight. The SU7 Ultra has 5 m$^2$ (54 sq ft) of Alcantara throughout its interior, including on the steering wheel, seats, doors, and dashboard. Xiaomi says that Alcantara was chosen to reduce light reflections and save up to 50% weight compared to conventional leather. The front seats have a 10-point massaging function, all the side windows are dual-glazed, and it is equipped with a 25-speaker audio system including speakers placed inside the driver's seat headrest. The infotainment system's software has a unique skin, and there are three artificial vehicle sound options.
The Ultra's chassis is based on the standard SU7 and 90.1% of its composition consists of varieties of high-strength steel and aluminium. It also features an FIA-grade roll cage integrated into the chassis. It has 21-inch wheels with Pirelli P Zero 5 tires. It has dual-chamber air suspension, which can independently adjust ride height and spring rate. It is equipped with a carbon ceramic brake system, with 430 mm × 40 mm (16.9 in × 1.6 in) disks and six-piston Akebono calipers in the front, and 410 mm × 32 mm (16.1 in × 1.3 in) disks and four piston calipers in the rear. It has a 100–0 km/h (62–0 mph) stopping distance of 30.8 m (101 ft), and Xiaomi says it can stop from 180 km/h (112 mph) 10 times in succession without losing braking performance.
The Ultra receives an upgraded sensor suite for its Xiaomi HAD supervised autonomous driving system consisting of 3 LiDARs, 5 mmWave radars, and twelve cameras.
The Ultra features a mostly Xiaomi self-developed powertrain, including the debuting HyperEngine V8s motor, electric power electronics, and thermal management system. Xiaomi co-developed the battery pack in collaboration with CATL, and designed the battery controller as part of its contribution. It is designed with track use in mind and uses CATL's new Qilin 2.0 NMC battery cells. The pack is assembled using a cell-to-chassis design, which achieves 77.8% volumetric utilization and allows for a 17-millimetre (0.67 in) decrease in cabin floor height. The battery operates at 900 V and has a maximum peak output of 1,330 kW (1,784 hp; 1,808 PS), or 800 kW (1,073 hp; 1,088 PS) at 20% charge. It can be charged at a rate of up to 490 kW (5.2C), allowing for a 10-80% charge time of 11 minutes. It adopts a dual-layer pack cooling design, which Xiaomi claims increases cooling capacity by 60% compared to conventional methods.
The SU7 Ultra is powered by three electric motors developed by Xiaomi, which are two HyperEngine V8s and one HyperEngine V6s, reaching a combined power output of 1,138 kW (1,547 PS; 1,526 hp) and total torque output of 1,770 N⋅m (1,305 lb⋅ft). The two V8s motors output 425 kW (578 PS; 570 hp) and 635 N⋅m (468 lb⋅ft) of torque each, and the V6s motor also found in the SU7 Max outputs 288 kW (392 PS; 386 hp) and 400 N⋅m (295 lb⋅ft) of torque. The HyperEngine V8s has a maximum speed of 27,200 rpm, is 98.11% efficient, and has a power density of 10.14kW/kg, while the V6s can go up to 21,000 rpm.
The SU7 Ultra can accelerate from 0 to 100 km/h (62 mph) in 1.98 seconds, 0 to 200 km/h (124 mph) in 5.96 seconds, and 0 to 300 km/h (186 mph) in 15 seconds, runs the 0–400 m (0.249 mi) in 9.23 seconds, and has a top speed of over 350 km/h (217 mph). The SU7 Ultra hit a top speed of 359.71 km/h (224 mph) at the CATARC Yan Cheng Automotive Proving Grounds, which CEO Lei Jun claimed was limited by the test facility. It set the record for the fastest mass-produced vehicle at the Shanghai International Circuit with a laptime of 2:09.944.

### SU7 Ultra prototype

The SU7 Ultra was previewed by a prototype model, which was unveiled on 19 July 2024, during a 2024 annual speech by Lei Jun. During the event, Xiaomi revealed details on the new HyperEngine V8s motor and CATL co-developed battery which would be used in the eventual production version. The prototype has the same powertrain as the production version, but is fitted with a fully carbon fiber body and lacks a finished interior, resulting in a weight of slightly under 1,900 kilograms (4,200 lb). At the event, Xiaomi said it intended to set a new record in the four-door electric sedan category at the Nürburgring Nordschleife, which was held by the Porsche Taycan Turbo GT at the time.
The exterior features a significant aerodynamic overhaul, with large front air vents that lead to large hood exit vents, a significant front splitter and side skirts, along with a large rear wing and diffuser, allowing for up to 2,145 kilograms (4,729 lb) of downforce. Due to the additional aerodynamic bodywork, the vehicle has larger dimensions than the standard SU7, with a length of 5,260 mm (207.1 in), width of 2,064 mm (81.3 in), and height of 1,406 mm (55.4 in), but the wheelbase is maintained. It is equipped with AP Racing fixed six-piston brake calipers designed for racing, and racing brake pads capable of operating at over 800 °C (1,500 °F). In addition, the motors are able to apply 0.6G of reverse torque, for a total of 2.36G of deceleration and a 100–0 km/h (62–0 mph) stopping distance of 25 metres (82 ft).
On 24 October 2024, a prototype version of the SU7 Ultra achieved the official lap record for a four-door car on the Nürburgring Nordschleife at 6:46.874, driven by racing driver David Pittard.
