2024 Xiaomi SU7 Dimensions, Size & Specs

The Xiaomi SU7 measures between 1963 mm and 1970 mm in width, which is roughly 77.3 to 77.6 inches. This width provides a stable and confident stance on the road, enhancing handling and cornering stability. While the width contributes positively to vehicle stability, it can pose minor challenges in tight parking spots or narrow urban streets. Nevertheless, this size is typical for luxury and full-size sedans, balancing exterior space with the practicality needed for everyday driving.

The height of the Xiaomi SU7 ranges from 1440 mm to 1465 mm, approximately 56.7 to 57.7 inches. This relatively low height supports a sleek, aerodynamic profile, which can help improve fuel efficiency and reduce wind noise at highway speeds. Internally, this height is sufficient to provide comfortable headroom for occupants, contributing to a spacious and airy cabin feeling without compromising the sedan’s sporty design elements.

The curb weight of the Xiaomi SU7 ranges from 1980 kg to 2360 kg (about 4365 to 5207 lbs). This wide range reflects different configurations, including engine, drivetrain, and equipment levels. A heavier curb weight generally indicates a more robust build and possibly increased luxury features or battery capacity in hybrid/electric models. While heavier weight can negatively impact fuel efficiency and acceleration, manufacturers usually balance this with powerful engine options and advanced technologies to maintain strong performance metrics.

The Xiaomi SU7's maximum weight, or Gross Vehicle Weight Rating (GVWR), ranges between 2430 kg and 2810 kg (approximately 5359 to 6196 lbs). GVWR is critical as it encompasses the vehicle’s curb weight plus passengers, cargo, and additional load. Staying within this limit is essential for safety, handling, braking performance, and preventing premature wear. The relatively high GVWR ensures the SU7 can comfortably carry a full complement of passengers and luggage without compromising structural integrity or safety.

The luggage capacity of the Xiaomi SU7 varies from 454 to 517 liters, which is approximately 16.0 to 18.3 cubic feet. This spacious trunk size allows for easy storage of groceries, luggage for long trips, or sports equipment. This range in capacity might be due to different trims or configuration of rear seating. For a sedan classified around this size, the luggage volume is quite generous and competitive, offering practical usability without compromise on passenger comfort.

The Xiaomi SU7, with its length of up to 5115 mm (201.3 inches) and width near 1970 mm (77.6 inches), fits within the space typically allocated for standard residential garages, which are usually about 6 meters (20 feet) long and 3 meters (10 feet) wide. However, while the fit is generally possible, tight garage spaces may require careful maneuvering due to the vehicle's substantial size, especially considering door opening clearance and any added side mirrors or roof attachments. It's advisable to measure your garage space if you live in a compact or older style home to ensure comfortable ease of parking and exit.

As the first generation SU7 starting production in 2023, Xiaomi’s SU7 does not have a predecessor model for direct comparison. However, this inaugural model sets the benchmark for the brand’s sedan segment focusing on maximizing space, comfort, and technology. Its dimensions and weight are comparable to other full-size sedan competitors, establishing a strong footprint for Xiaomi's automotive aspirations. Future model updates and versions will likely benchmark changes against this baseline for improvements in size efficiency and reduction in weight where feasible.

The Xiaomi SU7 positions itself firmly in the full-size luxury sedan segment. When compared to competitors like the BMW 5 Series, Mercedes-Benz E-Class, or Audi A6, the SU7 offers comparable or slightly larger dimensions, with lengths ranging up to 5115 mm (201.3 inches) and a width near 1970 mm (77.6 inches). Its curb weight also aligns with similarly equipped sedans, reflecting a well-built, feature-packed vehicle. Luggage capacity ranging from 454 to 517 liters is competitive, often matching or exceeding rivals, providing an edge in practical usability. Rim sizes between 19 and 21 inches and a wide array of tire options enhance aesthetics and handling flexibility similar to premium German sedans.

The Xiaomi SU7 offers rim sizes of 19, 20, and 21 inches with a variety of tire sizes such as 245/45 R19, 265/40 R20, 265/35 R21, 245/40 R20, 245/35 R21, and 305/30 R21. Larger rims, like 20 or 21 inches, provide a more aggressive stance and improved aesthetic appeal while often enhancing cornering performance due to lower profile tires. However, bigger rims may result in slightly firmer ride comfort because of reduced sidewall cushioning. Smaller 19-inch rims contribute to a more comfortable ride with better shock absorption but may sacrifice some cornering responsiveness. This selection allows buyers to tailor the SU7’s performance and look according to their preferences.
