The chassis system, safety structure, and driver assistance also demonstrate architectural-level integration capabilities, reflecting the full-chain in-house R&D strength from the powertrain to chassis control, and from the body structure to perception intelligence.
 

The ZEEKR 9X fills the gap for Chinese brands in the full-size SUV segment and aims to push hybrid models to new technical heights through architectural empowerment.

01

 Vast-S:

Dedicated Architecture for Hybrid Technology
 

Vast-S is ZEEKR's luxury hybrid-exclusive architecture, upgraded from the SEA vast architecture. Compared to mainstream hybrid platforms, it features three core characteristics: a full-stack 900V high-voltage platform, a megawatt-level three-motor electric drive system, and high-performance fast charging and electric drive efficiency on par with pure electric vehicles. These features technically enable the ZEEKR 9X to surpass the capabilities of existing hybrid SUVs.

High-Voltage System and Powertrain Synergy
 

The Vast-S architecture introduces the only 900V system in the hybrid field, a technology transfer from pure electric architectures. This high-voltage system supports 6C-rate fast charging, replenishing 20% to 80% in just 9 minutes, improving charging efficiency by 2-3 times compared to mainstream 400V hybrid models.
 

A 70kWh large-capacity battery pack, combined with an in-house thermal management system, achieves a CLTC pure electric range of 380 km—the highest record for hybrid SUVs globally.

The electric drive system consists of a three-motor setup with a total output power of 1030 kW, equivalent to over 1400 horsepower. The vehicle accelerates from 0 to 100 km/h in under 3 seconds, with no performance degradation in battery-depleted conditions.

The ZEEKR 9X combines a 2.0T hybrid-specific engine with the world's most powerful 145 kW range extender generator, ensuring high-energy response even when the battery is depleted. In various driving conditions—fully charged, high-speed, or uphill—the vehicle seamlessly switches between pure electric drive, engine direct drive, range-extending generation, and parallel drive modes for optimal energy efficiency.

Electric Drive Performance and Thermal Efficiency
 

ZEEKR's in-house developed 2.0T hybrid-specific engine achieves a thermal efficiency of 46%, avoiding energy losses from "fuel-to-electricity-to-motion" conversion through a high-speed direct-drive mechanism.
 

In battery-depleted high-speed scenarios, the system can replenish the battery while driving, recovering 20 kWh per hour at 120 km/h, achieving a 30% to 80% charge in 90 minutes.

For noise control, dual-mass flywheels, eccentric crankshaft design, and acoustic insulation in over 90% of the vehicle area keep engine noise impact below 0.5 dB, making it nearly imperceptible.
 

Thermal Management and Fast Charging Integration

High-rate large-battery thermal control is another key feature. The in-house hybrid thermal management system, optimized for three-electric layout, supports fast charging while ensuring electric drive efficiency and thermal stability across modes, delivering stable and efficient performance in all conditions. Its economy is significantly better than comparable products, with 5%-10% lower fuel consumption than 1.5T range-extender systems.
 

Vast-S not only introduces 900V, megawatt electric drive, and 6C fast charging to hybrid systems but also integrates range-extending, hybrid, and pure electric modes through vehicle energy management, achieving full-scenario coverage.
 

This represents a new paradigm for hybrid performance through architectural redesign—no longer a compromise between traditional fuel and electric drive but a fusion of efficiency, performance, and energy replenishment.

 ZEEKR 9X:

Architecture-Integrated Vehicle System Engineering

The ZEEKR 9X not only breaks through in powertrain technology but also achieves system-level coordination in chassis control, body structure, and intelligent driver assistance, demonstrating the depth of architectural vehicle development.

Chassis System: Electric Control Integration and All-Terrain Capability
 

As a full-size SUV over 5.2 meters long, the ZEEKR 9X achieves "small-car" handling through the Vast AI Digital Chassis. This system consists of dual-chamber dual-valve air suspension, a 48V active stabilizer bar, and the Dinghai Intelligent Central Controller.
 

The air suspension offers 110mm of travel and a maximum ground clearance of 288mm, enabling adaptive height adjustment for off-road or high-speed driving. The dual-valve damping system has 2-3 times the bandwidth of single-valve systems for dynamic damping control.

The 48V active stabilizer bar responds in just 0.2 seconds with a maximum torque of 1400 Nm. Beyond roll control during turns, it features collision lift functionality, raising the chassis on the impact side within 0.7 seconds to redirect collision forces to the body sill beam, reducing side intrusion by up to 27%.

The Dinghai Intelligent Controller, with AI at its core, integrates powertrain, steering, suspension, and braking systems while leveraging perception data from the onboard AI driver assistance for unified coordination. Functions include blowout stability control, crosswind mitigation (limiting body drift to 20 cm in 10-level winds), and seven all-terrain driving mode recognition and adaptation.

Body Structure: Systematic Passive Safety
 

The ZEEKR 9X's body torsional stiffness reaches 41,600 Nm/°, among the highest for full-size SUVs. High-strength steel and aluminum alloys account for over 91% of the structure, with 2000 MPa ultra-high-strength steel used for A/B pillars and key side-impact zones.
 

ZEEKR's innovative "one-piece door ring + sunroof ring + rear casting structure" system forms a closed-loop collision load path. The one-piece hot-formed sunroof ring withstands 4.2 times the vehicle's weight in roof crush tests, while the rear casting consolidates over 80 parts into three main components, reducing welds by thousands and improving rear collision energy absorption by 16%.
 

For active safety, the third energy-absorbing box" buffers impacts between the firewall and engine; the high-voltage distribution box features a flip mechanism to prevent secondary accidents from rear-end collisions; and the fuel tank collision block ensures safety in hybrid system oil-electric separation.
 

Driver Assistance: From High-Level Perception to Algorithm Closure

The ZEEKR 9X is equipped with H7 and H9 intelligent driver assistance systems. The H9 system, based on the Thor-U chip with 1400 TOPS computing power, supports L3 capabilities. Its Smart AI Agent framework enables end-to-end full-scene perception and decision-making.
 

The system completed nationwide NZP (mapless city navigation assist) deployment within six months, supporting full-path assistance including multi-lane ramps, ETC entrances/exits, roundabouts, and parking-to-parking navigation.
 

Continuous OTA updates, high-precision maps, multi-sensor fusion (cameras, radar, ultrasonic, lidar), and redundant control algorithms cover urban, highway, and parking scenarios.

The ZEEKR 9X embodies "architectural thinking" in vehicle system engineering: powertrain, electric chassis, safety structure, and driver assistance form a complete loop. Structural, perceptual, and execution synergy enhances safety and performance while delivering a balanced driving experience through hardware-software integration.

Summary
 

The ZEEKR 9X is a system solution for the high-end new energy era, built on architectural leadership. Supported by the Vast-S architecture, it comprehensively matches or surpasses international luxury brands in powertrain, electric control, structure, safety, and intelligence.
 

As demand grows for pure electric experience, luxury performance, and intelligent safety, the ZEEKR 9X's "architectural hybrid" represents a valuable innovation.​​​​
