V. Structural Advantages

Powertrain

• Cummins ISD160 50 Engine (160 HP): Delivers reliable power and excellent fuel efficiency. The 4-cylinder diesel engine is specifically calibrated for off-road applications, providing strong low-end torque for climbing steep grades and navigating soft terrain. Selectable Euro 2–6 emission standards allow this vehicle to meet diverse global environmental regulations.

• Fast Gear 6DS60T-B Transmission: The 6-speed manual gearbox is engineered for durability in demanding conditions, with gear ratios optimized for both highway cruising and low-speed off-road maneuvering.

• ZNC580 Transfer Case: Provides reliable power distribution between front and rear axles, enabling true 4×4 all-wheel drive capability.

Drivetrain & Chassis

• 5T Front Drive Axle: Heavy-duty construction provides exceptional load-bearing capacity and steering precision on uneven terrain.

• 10T Rear Drive Axle: Engineered to handle heavy loads and provide maximum traction on soft or slippery surfaces.

• 230 (6+4) Double-Layer Frame: The reinforced frame provides exceptional torsional rigidity, preventing chassis flex during extreme off-road maneuvers and ensuring long-term durability.

Braking & Safety Systems

• EPB (Electric Parking Brake): Convenient electronic parking brake for safe parking on inclines.

• ESC (Electronic Stability Control): Maintains vehicle stability during cornering and emergency maneuvers on loose surfaces.

• ABS (Anti-lock Braking System): Prevents wheel lockup during emergency braking on wet or icy roads.

• HHC (Hill Hold Control): Prevents rollback when starting on steep inclines, reducing driver stress on mountainous routes.

Cab Comfort & Technology

• Rotary Gear Selector: Ergonomic transmission control for easy operation.

• Auto A/C: Automatic climate control maintains comfortable cabin temperature in extreme weather conditions.

• Power Windows & Central Locking: Convenience features for passenger comfort and security.

• Remote Key: Keyless entry for driver convenience.
