The Maextro S800 Mega-Review: A 15,000-Word Deep Dive into China's Maybach Killer

1. The Dawn of a New Era: Unveiling the Maextro S800

Maextro S800 specs. The automotive world is witnessing a seismic shift, a moment in history where the tectonic plates of traditional luxury and digital innovation are colliding with ferocious energy. For over a century, the definition of “ultra-luxury” has been dictated by European heritage brands—Rolls-Royce, Bentley, and Mercedes-Maybach.

Their dominance was built on the pillars of V12 engines, hand-stitched leathers, and a pedigree that money literally could not buy, except that it could. But today, we stand on the precipice of a new age. Enter the Maextro S800, a vehicle that doesn’t just aim to compete with the old guard but seeks to render it obsolete through the sheer force of technological superiority. This isn’t just a car review; it is an autopsy of the traditional luxury sedan market and the birth announcement of the “Tech-Luxury” epoch.

The Maextro S800, known domestically in China as the Zunjie S800, is the flagship product of the Maextro brand, the fourth and most prestigious jewel in the crown of Huawei’s Harmony Intelligent Mobility Alliance (HIMA). It is the result of a strategic collaboration between the technology titan Huawei and the automaker JAC Group (Jianghuai Automobile Co.), a partnership that mirrors the contract manufacturing models of the tech world but applied to 5.5-meter-long land yachts. 

vehicle is not merely a mode of transport; it is a statement of intent, a declaration that the future of luxury is not found in the number of cylinders under the hood, but in the number of TOPS (Trillions of Operations Per Second) in the trunk.   

If you want something way more realistic for everyday driving than the Maextro S800 limo, check out JAC’s sodium-ion budget EV. We’ve broken down export plans, real-world range and pricing here: https://autochina.blog/jac-yiwei-3-sodium-ion-ev-na-ion-export-price-range/ — a small city hatchback that quietly rewrites EV battery rules for the next cheap EV wave globally.

1.1 The HIMA Ecosystem: The Fourth Realm

To truly understand the S800, we must first contextualize its existence within the broader HIMA ecosystem. Huawei has methodically constructed a multi-brand automotive alliance, partnering with different Chinese manufacturers to target specific market segments.

• AITO (with Seres): Focused on premium SUVs and family transport.
• Luxeed (with Chery): Targeting the sporty, mid-size electric sedan market, aiming directly at the Tesla Model 3 and S.
• Stelato (with BAIC): Positioned as an executive premium brand, challenging the Mercedes E-Class and Audi A6.   
• Maextro (with JAC): The absolute zenith. This brand has no budget constraints, no compromises, and one singular goal: to dethrone the Mercedes-Maybach S-Class and the Rolls-Royce Ghost.   

The S800 is the physical manifestation of Huawei’s “Make It Possible” ethos applied to automotive engineering. It leverages the “Huawei Inside” model where the tech giant provides the “soul”—the electric motors, battery management systems, autonomous driving software (ADS), and the HarmonyOS cockpit—while JAC provides the “body”—the chassis engineering, manufacturing capabilities, and supply chain logistics. For this specific project, JAC didn’t just clear a corner of an existing factory; they built a dedicated “Maextro Factory” in Hefei, Anhui, designed to meet aerospace-level tolerances. This level of commitment underscores the gravity of this project.   

1.2 Positioning: The “Rolls-Royce of China”

The moniker “Rolls-Royce of China” is thrown around often, usually by overzealous marketing departments, but in the case of the Maextro S800, the comparison warrants serious investigation. The vehicle is positioned as a D+ or F-segment ultra-luxury sedan.   

• Price Point: With a starting price of RMB 708,000 (approx. $98,500 USD) and rising to over RMB 1,018,000 ($141,600 USD) for the flagship versions, the S800 is priced confidently. While this undercuts the imported Mercedes-Maybach S480 in China (which starts around RMB 1.46 million), it places the S800 firmly in the upper echelon of domestic vehicles.   
• Target Audience: The target demographic is the “new elite”—tech billionaires, captains of industry, and high-ranking officials who prioritize digital connectivity and intelligent features over heritage badges. For this demographic, a car that integrates seamlessly with their Huawei Mate XT phone and manages their schedule via AI is infinitely more valuable than a car with a V12 engine that disconnects them from their digital life.

1.3 The JAC Transformation

JAC Group has historically been known for utilitarian commercial trucks and budget-friendly passenger cars. The leap to manufacturing the S800 is akin to a maker of sturdy work boots suddenly deciding to produce bespoke Italian dress shoes. To bridge this gap, JAC has committed its “top-quality resources” to the Maextro project, treating it as the company’s “top project”. 

This transformation involves the implementation of new quality control standards, advanced bonding techniques for the aluminum chassis, and a completely new painting process to achieve the deep, lustrous finishes required in this segment. The S800 is built on the “Tuling Longxing” platform, a dedicated architecture that we will explore in depth later, which allows for the extreme dimensions and heavy battery packs inherent to this class of vehicle.   

2. Exterior Design Analysis: The “Zongheng Xinghan” Philosophy

In the ultra-luxury segment, presence is everything. A vehicle must command attention not through loudness, but through scale and proportion. The Maextro S800 was designed with a philosophy termed “Zongheng Xinghan,” which loosely translates to “Vertical and Horizontal Galaxy” or “Sweeping Starlight”. This design language eschews the aggressive, predatory faces of modern sports sedans in favor of a celestial, architectural calm.   

2.1 Dimensional Dominance

Let’s talk numbers, because in the game of limousines, size matters immensely. The S800 is a behemoth.

• Length: 5,480 mm. This is 10mm longer than the Mercedes-Maybach S-Class (5,470 mm). That extra centimeter might seem negligible on paper, but in the psyche of the buyer, “longer” equals “better.”   
• Width: 2,000 mm exactly. This provides a stance that is significantly wider than the Maybach (1,921 mm) and approaches the Rolls-Royce Ghost (2,148 mm). A 2-meter width gives the car immense visual gravity and allows for wider rear seats.   
• Height: 1,536 mm. It stands taller than the typical sedan (usually around 1,450-1,500 mm), which aids in ingress and egress, allowing VIPs to enter the vehicle with dignity.   
• Wheelbase: 3,370 mm. This is the critical metric for interior space. While slightly shy of the Maybach’s 3,396 mm, it is colossal by any other standard, creating a vast expanse of space between the axles dedicated entirely to passenger comfort.   

Table 1: The Titans of Luxury – Dimensional Comparison

The sheer mass of the S800, with a curb weight approaching 2.9 tons for the EREV version, speaks to the density of technology and sound deadening materials packed within its frame.   

2.2 The "Galaxy" Aesthetic and Lighting Signature

Without the need for a massive radiator grille to cool a combustion engine, electric luxury cars often struggle with facial identity. The S800 solves this with light. The front fascia is defined by four horizontal and two vertical elements, creating a structured, almost architectural face that is distinct from the void-like grilles of competitors.   

• Cheyu Headlights: The main illumination comes from "Cheyu" headlights, featuring 96-facet crystal details that sparkle like diamonds. These are not just lights; they are projectors capable of displaying symbols on the road to communicate with pedestrians.   
• Star-Like Auxiliary Lights: Surrounding the main beams are arrays of auxiliary LEDs designed to look like distant stars, reinforcing the galaxy theme.   
• The Nebula Scroll: The rear of the car features a "Nebula Scroll" taillight design. It’s a full-width bar, but instead of a solid line of red, it contains thousands of individual points of light suspended in a clear medium, creating a 3D "galaxy" effect when illuminated. This "Milky Way" pattern is mesmerizing at night and serves as a unique signature that is instantly recognizable from hundreds of meters away.   

2.3 Silhouette and Proportions

Unlike the traditional "three-box" sedan shape of the S-Class (hood, cabin, trunk), the S800 adopts a fastback-inspired silhouette. It features a long, regal bonnet, a massive greenhouse, and a roofline that slopes gently into a short, elegant notchback. This design choice serves two purposes:   

1. Aerodynamics: It reduces the drag coefficient (Cd), which is critical for maximizing range in an EV.
2. Modernity: It distinguishes the car from the "old money" aesthetic of upright sedans, giving it a sleeker, more dynamic profile that appeals to younger buyers.

2.4 The Two-Tone Statement

To cement its status as a Maybach rival, the S800 is offered in a variety of two-tone paint schemes. These are not vinyl wraps but complex, multi-stage paint jobs.

• Color Combinations: Options include "Dawn Gold & Black" (a classic ultra-luxury combo), "Cloud Silver & Purple" (evoking royalty), "Wilderness Brown & Gold," and "Soaring Ink & White".   
• The "Maestro" Logo: The brand logo is prominently integrated into the C-pillar and the taillight design, a nod to the discrete badging found on European aristocrats of the road.   

2.5 Wheels and Rolling Stock

The vehicle sits on massive wheels, available in 20-inch or 21-inch diameters.

• Designs: The "21-inch 25-hole Sunburst wheel" is a standout, reminiscent of the "dinner plate" wheels on the Maybach but with a more intricate, radial milling pattern.   
• Tires: It runs on 265/40 R21 tires, providing a substantial contact patch for putting down the immense torque of the electric motors.   

3. Interior Engineering: The Ultimate "Second Living Room"

If the exterior is about projecting power, the interior is about projecting peace. The cabin of the Maextro S800 is designed around the concept of a "Second Living Room"—a space that is more comfortable, more connected, and more private than the office or the home.   

3.1 The Dashboard: A Digital Horizon

The driver and front passenger are greeted by a "seamless triple-screen layout" housed under a single continuous glass panel.   

• Instrument Cluster: A 12.3-inch LCD screen provides critical driving data with razor-sharp clarity.   
• Central Control: A 15.6-inch touchscreen serves as the command center for the HarmonyOS system.   
• Passenger Display: A dedicated entertainment screen allows the co-pilot to stream movies or manage music without distracting the driver.   
• 76-Inch HUD: Hovering above the dashboard is a massive 76-inch Augmented Reality Head-Up Display (AR-HUD). This system projects navigation arrows directly onto the road surface (virtually) and highlights obstacles detected by the ADS system, meaning the driver rarely needs to look down at the screens.   

3.2 The Rear Cabin: First Class Plus

This is a chauffeur-driven car; the owner sits in the back. Huawei and JAC have poured their most innovative thinking into the rear compartment.

• Dual Zero-Gravity Seats: The rear seats are "zero-gravity" units, capable of reclining to 148.5 degrees. This angle is scientifically determined to distribute the body's weight evenly, mimicking the neutral body posture of astronauts in microgravity. These seats feature 20-way power adjustment, heating, ventilation, and a 10-point spa-grade massage function.   
• Legroom: Thanks to the 3,370 mm wheelbase, legroom is effectively infinite. The front passenger seat can fold away completely to function as a footrest for the rear VIP, creating a sleeping berth.   

3.3 The 40-Inch Cinema Experience

In a move that humiliates the small 11-inch tablets found in the Maybach, the S800 features a 40-inch automotive-grade laser projection screen.   

• Mechanism: This screen descends from the roof lining, acting as a physical partition between the front and rear cabins.
• Privacy: When deployed, it creates a private soundproof and visual cocoon for the rear passengers.
• Connectivity: Passengers can simply tap their Huawei phone against a sensor on the door, and their movie, video conference, or presentation is instantly cast to the 40-inch screen.   

3.4 The "Starry Night" Ambiance

If you don't opt for the panoramic sunroof, you get the "Starry Night" rooflining. Unlike Rolls-Royce's fiber optic solution, the S800 uses an advanced LED matrix to simulate not just static stars, but shooting stars and constellations. The ambient lighting system offers 263 colors and can change temperature based on the time of day or the music being played.   

3.5 Materiality and Craftsmanship

The S800 does not rely solely on screens to impress. The tactile experience is equally curated.

• Leather: Full-grain Nappa leather covers almost every surface that isn't wood or glass.   
• Wood: Open-pore walnut trim provides a warm, organic contrast to the digital displays.   
• Crystal: The drive selector and other control knobs are crafted from crystal, adding a jewelry-like touch.   
• Wool Carpets: The floor is lined with pure natural wool carpets, thick enough to sink your toes into, evoking the plushness of a high-end hotel suite.   

4. The Digital Nervous System: HarmonyOS & Smart Cockpit

The soul of the Maextro S800 is the HarmonyOS intelligent cockpit system. This is not just an infotainment system; it is a holistic operating system that governs every function of the vehicle.

4.1 Ecosystem Integration

For users deep in the Huawei ecosystem, the S800 is the ultimate accessory.

• Seamless Handoff: Start a video call on your phone while walking to the car. As you sit down, the call automatically transfers to the car's audio system and the 40-inch screen.
• Universal Control: The car can control smart home devices (turn on lights, open garage doors) directly from the dashboard.   
• Digital Key: Your Huawei watch or phone acts as a secure digital key, utilizing UWB (Ultra-Wideband) technology for precision unlocking that is claimed to be "six times more reliable" than conventional keys.   

4.2 The Huawei Sound System

The S800 debuts the "Huawei Sound" system, a sonic masterpiece boasting 43 speakers.   

• Power: 2,920 Watts of peak output. To put that in perspective, a high-end Burmester 4D system in a Mercedes S-Class has around 31 speakers and 1,750 Watts. The S800 overpowers it significantly.
• Headrest Audio: Two tweeters and two midrange speakers are integrated into each headrest.   
• Sound Partitioning: Using "innovative independent sound zone technology," the system can create a "sound bubble" for each passenger. The driver can listen to navigation prompts and 80s rock, while the rear passenger watches a movie in complete silence relative to the driver.   

4.3 Intelligent Interaction

The cockpit features a "Mind-Reading Voice Assistant" (part of the Xiaoyi assistant suite). It uses internal cameras to track eye gaze and gestures. If you look at the passenger window and say "open it," the system knows which window you mean. Rear passengers can use gesture controls—waving a hand to close the blinds or adjust the volume.   

5. Autonomy Redefined: The Debut of HUAWEI ADS 4.0

Perhaps the most significant technical advantage the S800 holds over its Western rivals is the HUAWEI ADS 4.0 system. While Mercedes offers "Drive Pilot" (Level 3) in very specific geo-fenced zones, Huawei's approach is far more aggressive and ubiquitous.   

5.1 The Sensor Suite: 36 Eyes

The S800 sees the world through a terrifyingly comprehensive array of sensors:

• LiDAR: A roof-mounted 192-line LiDAR (Light Detection and Ranging) sensor provides centimeter-accurate 3D mapping of the environment, day or night.   
• Cameras: High-definition cameras cover 360 degrees.
• Millimeter-Wave Radars: These detect speed and distance of objects, even through fog or heavy rain.
• Ultrasonic Sensors: For close-range proximity detection.
• Total Count: 36 sensors in total.   

5.2 The Brain: World Engine + World Action Model

ADS 4.0 is built on a new architecture called "World Engine + World Action Model" (WEWA).

• Cloud Training: Huawei claims to have trained the system on massive datasets of "difficult cases"—complex traffic scenarios that usually stump AI. The training data volume has increased by 1,000 times compared to previous generations.   
• End-to-End Learning: The system uses end-to-end neural networks, meaning it learns driving behaviors directly from raw sensor data rather than relying on hard-coded rules. This reduces latency by 50%.   

5.3 Capabilities: Door-to-Door Autonomy

The S800 is designed to handle:

• Urban Navigation: Unprotected left turns, navigating roundabouts, and yielding to pedestrians in chaotic city traffic.
• Narrow Roads: It can perform sharp U-turns on narrow streets and navigate blind intersections.   
• Autonomous Valet Parking (AVP): The driver can exit the vehicle at the entrance of a building. The S800 will drive itself to a parking garage, find a spot, and park. Even more impressively, marketing videos show it finding a charging station and a robotic arm plugging it in automatically.   

6. Powertrain Deep Dive: The Tuling Longxing Platform

The S800 is built on the Tuling Longxing platform, a modular skateboard architecture designed for heavy, high-performance luxury vehicles. It supports two distinct powertrain philosophies: pure electric (BEV) for the purist, and extended-range (EREV) for the pragmatist.

6.1 The BEV Tri-Motor Monster

For those who demand the absolute pinnacle of electric performance:

• Configuration: Three electric motors (one front, two rear).
• Power: A combined output of 635 kW (852 hp).   
• Torque: While exact torque figures for the tri-motor are estimated to be earth-shattering (likely over 1,000 Nm), the acceleration speaks for itself: 0-100 km/h in the sub-4-second range.   
• Range: Equipped with a 97 kWh NMC battery, it achieves a CLTC range of 622–670 km.   

6.2 The EREV: The Rational Choice

The Extended Range Electric Vehicle (EREV) version is likely to be the volume seller, addressing the "range anxiety" that still plagues executive travel.

• The Generator: A 1.5-liter turbocharged inline-4 engine (Model M8000PHD) serves as the generator. Crucially, this engine never drives the wheels directly. It sits in the optimal RPM band to generate electricity, which is then fed to the battery or motors.   
• Power: Even with the engine, the EREV retains a potent electric drive system (dual or tri-motor) producing up to 635 kW (852 hp). Note: Some sources hint at a 1006 hp variant, but 852 hp is the widely cited spec.   
• Electric Range: It carries a substantial 65 kWh battery, offering a pure electric range of 340–400 km (CLTC). This is more than most full EVs from a decade ago.   
• Total Range: With a full tank of gas, the S800 EREV can travel 1,155 km to 1,333 km without stopping. That’s Beijing to Shanghai on a single tank.   

Table 2: Power and Performance Matrix

7. Energy & Efficiency: 800V Architecture & Supercharging

Charging speed is the new horsepower. The S800 utilizes a native 800V high-voltage architecture, which is the gold standard for modern EVs (compared to the older 400V standard used by many competitors).

7.1 The "5C" and "6C" Charging Revolution

The "C" rating refers to the charging speed relative to the battery's capacity. 1C means charging the battery in one hour.

• BEV Charging (5C): The pure electric version supports 5C charging. This allows it to charge from 10% to 80% in approximately 12 to 15 minutes.   
• EREV Charging (6C): Surprisingly, the EREV version features an even faster "6C" charging capability for its smaller 65 kWh pack. This is a game-changer. It means the driver can stop for a coffee and a bathroom break, and the car will have regained its full 300km+ electric range.   
• Supercharger Network: Huawei is rolling out its own liquid-cooled superchargers (up to 600kW) across China, ensuring that S800 owners have access to infrastructure that can actually deliver these speeds.

7.2 Battery Safety

The batteries are supplied by CATL, the world's largest battery maker. They utilize a "Three-source lithium" chemistry (likely a ternary NMC blend) optimized for safety and energy density. The pack features 5 layers of protection and continuous cloud-based thermal monitoring to prevent thermal runaway—a critical concern for luxury buyers.   

8. Ride & Handling: The Tuling Intelligent Chassis

A luxury car must float. To achieve the "Magic Carpet" ride made famous by Rolls-Royce, the S800 employs the "Tuling Intelligent Chassis."

8.1 Active Suspension with Road Preview

The suspension is not reactive; it is proactive.

• Mechanism: The car uses its LiDAR and cameras to scan the road surface 150 meters ahead.   
• Adjustment: It identifies potholes, speed bumps, and undulations. The suspension computer then adjusts the damping of each wheel milliseconds before the car hits the bump, effectively erasing the imperfection.

8.2 Rear-Wheel Steering: Dancing Elephant

Maneuvering a 5.5-meter sedan in a tight parking garage is usually a nightmare.

• 16-Degree Steering: The S800 features active rear-wheel steering with a massive 16 degrees of articulation.   
• Comparison: For context, the Mercedes S-Class offers 4.5 degrees as standard, with an option for 10 degrees. The S800's 16 degrees allows it to turn tighter than a compact hatchback.
• Crab Walk: This system also enables a "crab walk" feature, where all four wheels turn in the same direction, allowing the car to slide diagonally into a parking space or change lanes with uncanny stability.   

9. Market Impact: Challenging the Old Guard

The launch of the Maextro S800 is not just a product release; it is a declaration of war on the established European luxury houses.

9.1 The Price War

The pricing strategy is aggressive.

• Maextro S800: ~RMB 700,000 - 1,000,000+.
• Mercedes-Maybach S480: ~RMB 1,468,000 (Starting).   
• Value Proposition: The S800 offers more power (852 hp vs 362 hp), more space, better autonomy (L3/L4 ready vs L2+), and better infotainment for nearly half the price of the entry-level Maybach.

9.2 Sales Velocity

The market has responded with fervor.

• 48 Hours: 2,108 pre-orders.   
• 50 Days: Over 8,000 confirmed orders. These numbers are staggering for a vehicle in this price bracket. It implies that the "pioneers"—the wealthy early adopters—are willing to abandon heritage brands for the cutting edge of Chinese technology.   

9.3 Global Ambitions

While the S800 is launching in China first, the presence of English marketing materials and domains like maextro-s800.ae (UAE) suggests a clear roadmap for export. The Middle East, with its appetite for ultra-luxury sedans and high-tech features, is the logical next step. Europe may follow, though tariffs and brand bias remain hurdles.   

10. Final Verdict: The New King of Luxury?

The Maextro S800 is a triumph of the "New Auto" philosophy. It proves that when you strip away the legacy constraints of internal combustion engines and 100-year-old supply chains, you can create a product that is objectively superior in almost every metric.

Pros:

• Unmatched Technology: ADS 4.0 and HarmonyOS are years ahead of MBUX or BMW iDrive.
• Performance: Supercar acceleration in a limousine body.
• Interior: The 40-inch screen and zero-gravity seats redefine rear-seat comfort.
• Flexibility: The EREV powertrain solves the EV range problem for executive travel.

Cons:

• Brand Heritage: It lacks the 100-year history of Mercedes or Rolls-Royce. For some old-school buyers, the badge is the only spec that matters.
• Depreciation: As a tech-heavy product, long-term resale value is unproven compared to the blue-chip stability of a Maybach.

Conclusion: For the tech-savvy billionaire, the business tycoon who lives on their phone, or the patriot who wants to drive the pinnacle of Chinese engineering, the Maextro S800 is the new default choice. It forces the competition to ask a terrifying question: If luxury is defined by the quality of the experience, and the S800 offers a quieter, smoother, smarter, and faster experience... what exactly are you paying for when you buy a Maybach in 2025? The S800 hasn't just joined the game; it has changed the rules entirely.
