Geely Cruiser 700 Plug-in Hybrid SUV Reveals Advanced Dual-Motor Rear Axle Technology

Geely is preparing to launch the Geely Cruiser 700 plug-in hybrid SUV, a model that will introduce the company's dedicated new-energy off-road architecture. Unlike platforms adapted from conventional combustion-engine vehicles, this architecture has been engineered specifically around electrified powertrains. The vehicle was initially previewed in March as Geely’s response to established off-road SUVs and has since been spotted undergoing production testing in China ahead of its market debut.

Native New-Energy Off-Road Platform

Publicly available information indicates that the platform combines a three-motor four-wheel-drive system with active hydraulic suspension, front and rear double-wishbone suspension, and an integrated-frame body structure. The architecture is also reported to achieve torsional rigidity exceeding 40,000 N·m/deg. These specifications highlight Geely’s intention to deliver a vehicle capable of combining off-road capability with the performance and responsiveness expected from modern electrified drivetrains.

Patent Reveals Rear Axle Traction Management Strategy

A recently reviewed patent, CN118769884A, offers additional insight into how the rear axle of the vehicle could manage traction. The patent focuses on a dual-motor rear axle arrangement where each rear wheel is driven independently by its own electric motor. This approach differs significantly from traditional four-wheel-drive systems that depend on mechanical differentials to distribute torque and accommodate varying wheel speeds during cornering.

How Dual-Motor Electric Axles Differ from Conventional Differentials

In a conventional drivetrain, a differential allows the left and right wheels to rotate at different speeds while maintaining vehicle stability during turns. A dual-motor electric axle eliminates the need for a traditional differential gearset by enabling electronic control of each wheel through independent motors. This configuration delivers rapid torque vectoring and precise wheel-speed management. However, when one wheel loses grip, the torque produced by its motor cannot automatically transfer to the wheel that still has traction.

Fluid-Coupled Locking Mechanism Explained

The patent proposes a solution through a fluid-coupled locking mechanism positioned between the two rear drive shafts. Each electric motor drives its respective wheel through an independent reduction gear assembly. Between the coaxial shafts sits a coupling system consisting of two interlocking sections. One section contains damping fluid while the other incorporates an impeller rotating within that fluid chamber.

During normal driving, the rotational speed difference between the shafts remains relatively small. As a result, fluid resistance stays low, allowing smooth wheel-speed variation during cornering. When a significant speed difference develops, such as when one wheel loses traction on a slippery surface, the impeller increases fluid agitation. The resulting viscous resistance works against the speed difference and enables a portion of available torque to be transferred across the coupling.

Comparison with Traditional Limited-Slip Systems

The concept shares similarities with a viscous limited-slip differential, although its architecture is fundamentally different. Instead of being integrated within a conventional mechanical differential assembly, the coupling connects two independently powered electric drive shafts. This design allows the axle to maintain the torque-vectoring advantages of a dual-motor configuration while introducing an automatic torque-sharing capability during wheel-slip events.

Unlike brake-based traction control systems that reduce wheelspin by applying braking force to the slipping wheel, the patented system creates a direct torque-sharing path between the shafts. The characteristics of the damping fluid can also influence locking behavior, potentially enabling different calibrations for everyday road driving and demanding off-road applications.

Why the Technology Matters for Off-Road EVs

Many electrified off-road vehicles rely heavily on software-controlled braking interventions to mimic the behavior of locking differentials. The solution proposed by Geely suggests a hardware-assisted approach capable of responding automatically when substantial wheel-speed differences occur. Such a system could provide more consistent traction performance while preserving the responsiveness associated with independently controlled electric motors.

The technology is particularly relevant because the Geely Cruiser 700 has already been confirmed to feature a three-motor four-wheel-drive configuration. Integrating a fluid-coupled locking mechanism could help balance precise torque vectoring with the traction advantages traditionally delivered by mechanical locking differentials in off-road vehicles.

Potential Production Application

Although the company has not disclosed the final production design of the Cruiser 700 rear axle, the patent offers one of the strongest indications yet regarding the vehicle’s approach to torque distribution. The system demonstrates how future electrified off-road platforms may combine software intelligence and hardware-assisted traction management to improve performance in low-grip environments.

Geely Galaxy Sales Performance

Beyond the technical developments, the Cruiser 700 is expected to become one of the most advanced vehicles within the rapidly growing Geely Galaxy portfolio. Sales data from April 2026 highlights the brand’s momentum across multiple vehicle segments.

The strong performance of existing models demonstrates growing market acceptance of the Galaxy lineup. The addition of the Cruiser 700 could further strengthen the brand’s position by introducing advanced electrified off-road technologies and expanding its presence in the premium adventure-oriented SUV segment.

Frequently Asked Questions

What makes the Geely Cruiser 700 different from traditional off-road SUVs?
The Geely Cruiser 700 is built on a dedicated electrified off-road architecture rather than a platform adapted from a combustion-engine vehicle. It combines a three-motor all-wheel-drive system, active hydraulic suspension, double-wishbone suspension, and advanced traction technologies. This approach enables precise torque control, improved responsiveness, and enhanced off-road capability while taking full advantage of electric powertrain characteristics and modern vehicle control systems.

How does the patented fluid-coupled locking mechanism work?
The system connects two independently driven rear drive shafts through a coupling that contains damping fluid and a rotating impeller. When wheel-speed differences become significant, the fluid creates viscous resistance that transfers part of the available torque between the shafts. This helps improve traction when one wheel loses grip. The design allows the vehicle to maintain dual-motor torque-vectoring benefits while adding an automatic torque-sharing function for challenging driving conditions.

Why is the dual-motor rear axle important for electric off-road vehicles?
A dual-motor rear axle enables each wheel to be controlled independently, providing highly accurate torque distribution and wheel-speed management. This improves vehicle handling and responsiveness compared with traditional mechanical systems. However, traction management can become more complex when one wheel slips. Geely’s patented solution addresses this challenge by introducing a hardware-assisted torque-sharing mechanism that may enhance off-road capability without sacrificing the advantages of independent electric motor control.
