2026 Models and Pricing Overview

In March 2026, Xiaomi officially launched the refreshed SU7 series, maintaining a three-tier structure but significantly upgrading the hardware under the hood. The 2026 models are built on the Modena architecture and utilize the new V6s Plus motors, which deliver higher efficiency and thermal management compared to the original 2024 launch versions.

Technical Specifications and Performance

The 2026 Xiaomi SU7 series has transitioned away from the 400V systems of its competitors, moving toward a 752V Silicon Carbide (SiC) platform for the Standard and Pro models. The Max variant utilizes a quasi-900V (897V) architecture, allowing it to achieve industry-leading charging speeds.

H3: Powertrain and Acceleration

All 2026 models are equipped with the HyperEngine V6s Plus, capable of reaching 22,000 rpm. The SU7 Max features a dual-motor all-wheel-drive setup producing 508 kW (690 hp) and 838 Nm of torque. This allows the Max to sprint from 0-100 km/h in just 3.08 seconds, with a top speed electronically limited to 265 km/h.

H3: Battery and Real-World Range

Xiaomi uses a Cell-to-Body (CTB) battery integration technology that increases cabin volume while improving structural rigidity. The battery capacities have been optimized for 2026:

• Standard: 73 kWh LFP battery (720 km CLTC)
• Pro: 96.3 kWh LFP battery (902 km CLTC)
• Max: 101.7 kWh Qilin battery (835 km CLTC)

Smart Cabin and HyperOS 2.0

The heart of the Xiaomi SU7 experience is the Smart Cabin, powered by the Qualcomm Snapdragon 8 Gen 3 processor. The interface runs on HyperOS 2.0, designed to provide a “smartphone-on-wheels” experience with zero learning curve for existing Xiaomi users.

The cabin features a 16.1-inch 3K central touchscreen, a 56-inch AR Head-Up Display (HUD), and two mounting points for Xiaomi Pad tablets on the back of the front seats. This creates a five-screen linkage system where passengers can control navigation, climate, and media independently. The 2026 update also improved the Super Xiao Ai voice assistant, which now manages 95% of vehicle functions with emotion-sensing capabilities.

Autonomous Driving: Xiaomi Pilot HAD

For 2026, Xiaomi has standardized its High-level Autonomous Driving (HAD) hardware across the entire range. This includes a roof-mounted LiDAR, 11 high-definition cameras, 12 ultrasonic radars, and a 4D millimeter-wave radar.

The system is powered by the NVIDIA DRIVE AGX Thor platform (in the Max variant) delivering up to 700 TOPS of computing power. This hardware enables “Point-to-Point” autonomous driving in urban environments and sophisticated “Valet Parking” that can navigate complex multi-story garages to find a specific spot automatically.

Design and Aerodynamics

The SU7 remains one of the most aerodynamic mass-produced sedans in the world, boasting a drag coefficient of 0.195 Cd. Its design, led by former BMW designer Sawyer Li and consultant Chris Bangle, emphasizes “minimalist luxury.”

New for 2026 are expanded color options including Capri Blue and Radiant Purple, alongside six redesigned wheel options like the 21-inch Forged Dual Plum Blossom rims. The exterior also features an active rear spoiler with four adjustment levels and an active air intake grille to balance cooling with aerodynamic efficiency.

Safety and Structural Integrity

Xiaomi has utilized a Hyper Die-Casting process to create a rear underbody that reduces the number of parts and weld joints, significantly increasing crash resistance. The 2026 model uses 2,200 MPa ultra-high-strength steel in its integrated roll cage.

Standard safety features now include 9 airbags (including new rear-side airbags) and a “bulletproof” battery coating that has passed over 1,000 rigorous safety tests. The vehicle’s Emergency Steering Assist can now perform dual-evasive maneuvers at speeds up to 135 km/h to avoid collisions.

Practical Information and Planning

For those interested in seeing or purchasing the Xiaomi SU7 in 2026, the company has expanded its retail footprint significantly.

• Delivery Lead Times: As of March 2026, estimated delivery for a new SU7 order in China is 12-16 weeks, depending on the variant and color customization.
• Service Centers: Xiaomi now operates over 500 service centers across 130 cities in China.
• Charging Infrastructure: The SU7 is compatible with all major Chinese charging networks. The Max variant can gain 670 km of range in 15 minutes using Xiaomi’s S4 Supercharging stations.

What the SU7 is

The Xiaomi SU7 is a four‑door electric sedan with a sport‑oriented design, rear‑wheel‑drive‑biased powertrain, and a focus on high performance, fast charging, and smart‑tech integration. It is built on Xiaomi’s own EV platform and uses a dual‑motor all‑wheel‑drive layout in higher trims, with a single‑motor rear‑drive version available in some markets. The SU7 is positioned as a premium‑mass EV, aiming to undercut some international rivals on price while matching or exceeding their performance and tech features.

The SU7’s name “SU7” follows Xiaomi’s naming convention from its smartphone lineups, with the “SU” hinting at “speed‑unit” or “Sports Utility”‑style positioning and the “7” suggesting a flagship rank similar to the company’s numeric phone‑series (e.g., Xiaomi 14 vs Xiaomi 13). The car targets tech‑savvy urban buyers who value acceleration, charging speed, and a connected ecosystem alongside daily practicality.

Key markets and launch

The Xiaomi SU7 launched first in mainland China in 2024, with deliveries starting in selected cities and then rolling out nationwide through Xiaomi’s direct‑sales and partner‑service channels. The Chinese model is available in multiple trims and battery options, with pricing that puts the SU7 in the 30–40‑thousand‑dollar equivalent bracket, depending on configuration and subsidies.

In 2025–2026 Xiaomi has begun expanding the SU7 to selected international markets, starting with parts of Southeast Asia, the Middle East, and trials in some European cities, using pilot‑deliveries and small‑volume imports. The 2026 global rollout remains market‑by‑market, with full homologation and pricing adjusted for local taxes, charging‑infrastructure, and safety‑regulations.

Design and exterior

Body style and styling

The Xiaomi SU7 uses a fastback‑style sedan body with a low roofline, flush‑fit door‑handles, and a low‑drag‑optimised silhouette to help maximise driving range and high‑speed stability. The car features a closed‑grille front typical of pure EVs, slim LED‑style headlights, and a sculpted front bumper with active‑air‑intake‑style elements that help with cooling the battery and motors under hard use.

At the rear, the SU7 displays a wide‑light‑bar‑style tail‑lamp arrangement, a small spoiler integrated into the trunk lid, and underbody‑diffuser‑style contours that give the car a sporty, premium‑saloon appearance. The exterior colour palette includes solid, metallic, and premium‑paint options, with darker finishes and contrast‑roof variants used to emphasise the car’s low, wide stance.

Dimensions and practicality

The Xiaomi SU7 sits in the mid‑size electric‑sedan segment, with overall length around 4.8–4.9 metres, a wheelbase of roughly 2.9–3.0 metres, and a height that keeps the centre of gravity low for better handling. The wide body and long wheelbase translate into:

• A roomy rear cabin suitable for three adults on shorter trips,
• A boot / trunk of around 400–450 litres, competitive with other EV sedans, and
• Adequate boot‑opening geometry for loading luggage and bags despite the fastback shape.

The sedan form makes the SU7 more practical than two‑door EV coupes but slightly less versatile than SUV‑style bodies for very tall passengers or frequent bulky‑cargo loads. For most urban and family‑use cases, the SU7 strikes a balance between sporty looks and usable space.

Performance and powertrain

Motor and drive system

The Xiaomi SU7 is offered with two main powertrain options: a single‑motor rear‑drive (RWD) configuration in entry trims and a dual‑motor all‑wheel‑drive (AWD) setup in higher‑performance trims. The AWD version uses an electric motor on each axle, with a combined peak output in the high‑hundreds of kilowatts, placing the SU7 firmly in the performance‑EV camp rather than a relaxed‑eco‑saloop role.

In the top‑spec AWD variant, the SU7 can accelerate from 0–100 km/h in around 4 seconds, with a top speed electronically limited to about 200–210 km/h, depending on battery‑state and regulatory‑limits. The rear‑drive version is still brisk for city‑and‑highway use, with 0–100 km/h acceleration in the mid‑5‑second range, making it suitable for buyers who care more about efficiency than maximum speed.

Battery and range

The Xiaomi SU7 uses a lithium‑ion battery pack mounted under the floor, with two primary battery‑capacity options (for example, roughly 70–80 kWh and 100–110 kWh usable) in key markets, depending on model year and trim. The larger pack is paired mainly with the AWD and higher‑performance variants to maintain usable range despite the car’s aggressive power output.

On a typical mixed‑driving‑cycle, the SU7 delivers:

• A WLTP‑style or local‑range benchmark of about 600–700 km for the larger‑battery AWD models,
• Around 450–550 km for the smaller‑battery RWD versions, depending on driving style and ambient temperature.

Real‑world highway‑driving at higher speeds can reduce those figures by 15–25%, while city‑driving and moderate‑highway use often meet or slightly exceed official‑range claims, especially with features like one‑pedal driving and regenerative‑braking tuned to recover more energy in stop‑and‑go traffic.

Driving modes and handling

The Xiaomi SU7 includes multiple driving‑modes selectable via the central‑screen or steering‑wheel buttons, such as Eco, Comfort, Sport, and sometimes a track‑oriented “Sport+” setting. These modes adjust:

• Motor‑response sharpness,
• Regenerative‑braking strength,
• Suspension‑firmness (if adaptive or performance‑suspension is fitted), and
• Steering‑weight and feedback.

The sedan’s low centre of gravity, wide track, and weight‑balanced battery layout help the SU7 feel agile and planted in corners, with minimal body‑roll compared to traditional ICE sedans. The electric‑torque‑vectoring‑style behaviour of the dual‑motor AWD system can also enhance stability when accelerating out of bends, giving the car a sport‑saloon character rather than a heavy EV barge feel.

Charging and efficiency

Charging speed and infrastructure

One of the Xiaomi SU7’s headline features is its high‑speed DC‑fast‑charging capability, which Xiaomi promotes as able to add hundreds of kilometres of range in under 20–25 minutes under ideal conditions. The car supports a high‑power CCS‑style DC‑connector (or GB‑type‑DC depending on market), with peak charging‑power in the 150–250 kW range, depending on battery‑state, pack‑size, and temperature.

On a suitable high‑power DC charger, the SU7 can:

• Charge from around 10–20% to 80% in roughly 15–25 minutes,
• Add 100–200 km of range in about 10 minutes, depending on charger‑power and battery‑condition.

For daily use, the SU7 is also compatible with AC‑wall‑box and public 11–22 kW AC charging points, with typical home‑or‑workplace‑charging times of 6–10 hours from 0–100% on a 11–22 kW source, depending on the variant.

On‑board energy use

The Xiaomi SU7 includes energy‑monitoring tools in its central infotainment screen, showing real‑time kWh/100 km consumption, estimated range, and distance remaining to the next‑planned‑destination. The RWD‑only versions are generally more efficient than the AWD‑performance trims, with consumption figures that place the SU7 in line with other mid‑range EV sedans.

Typical efficiency figures in mixed‑use conditions are around:

• 16–19 kWh/100 km for the RWD variants, and
• 18–22 kWh/100 km for the AWD trims, depending on driving style and weather.

The car’s aerodynamic design, low‑rolling‑resistance tyres (on some trims), and regenerative‑braking system all help keep energy use under control, while still allowing the SU7 to deliver strong performance when the driver demands it.

Interior and cabin tech

Cabin layout and materials

The Xiaomi SU7 features a driver‑centric cabin with a horizontal dash layout, a large central screen in front of the driver, and a second display in the centre‑stack for infotainment and vehicle‑settings. The materials mix includes soft‑touch plastics, aluminium‑style or synthetic‑metal trim, and fabric or leather‑style upholstery, depending on trim level and market.

The rear seats offer legroom and headroom that are generous for the segment, with:

• Adjustable rear‑seatback angles in some trims,
• Individual USB‑C or phone‑charging ports, and
• Climate‑controller‑style vents or diffusers.

The SU7’s fastback‑style roofline does reduce rear headroom slightly compared with a more upright‑sedan design, but most adults will still find the back‑seat area comfortable for medium‑distance trips.

Xiaomi HyperOS and connectivity

The Xiaomi SU7 runs Xiaomi’s HyperOS‑based infotainment system, extending the company’s smartphone‑centric ecosystem into the car with deep integration for:

• Smartphone‑projection and app‑mirroring,
• Over‑the‑air (OTA) software updates, and
• Smart‑home and device‑control through the car’s centre‑screen when connected.

The system supports:

• Voice‑assistant functions for navigation, climate, and media,
• Online navigation and traffic‑data, and
• Seamless login and syncing with a Xiaomi account, so preferences, apps, and media‑libraries carry across devices.

This ecosystem‑style approach is a key differentiator for the SU7, especially for users who already own Xiaomi phones, tablets, and smart‑home devices.

Safety and driver‑aid features

The Xiaomi SU7 comes equipped with a comprehensive advanced driver‑assist suite, including multiple cameras, radars, and ultrasonic sensors. Standard features typically include:

• Adaptive cruise control,
• Lane‑centring and lane‑keeping,
• Automatic emergency braking, and
• Blind‑spot monitoring and rear‑cross‑traffic‑alert.

Higher trims may add higher‑level semi‑autonomous‑driving‑style functions such as auto‑lane‑changes on highways, traffic‑jam‑assist, and smart‑parking modes, marketed under Xiaomi’s own branding rather than third‑party‑names. The car’s structural‑safety design focuses on front and side‑impact protection, with multi‑airbag systems, reinforced battery‑enclosure, and crumple‑zone‑style engineering.
