The Delong New M3000 375HP 6×4 Tractor Unit is purpose-built for modern logistics fleets that demand durability, efficiency, and dependable performance. Designed for highway freight, container transport, and long-distance hauling, this tractor unit combines proven powertrain technology with a lightweight yet robust chassis, making it an ideal choice for both domestic and cross-border transportation.
With its high-roof sleeper cab, fuel-efficient engine, and reinforced axles, the Delong New M3000 delivers consistent performance under heavy loads while maintaining excellent driving comfort and operational economy.
Efficient Powertrain Built for Heavy Transport
At the heart of the Delong New M3000 is the Weichai WP10H375E50 diesel engine, engineered to provide a strong balance between power output and fuel efficiency. This 9.5-liter, inline 6-cylinder engine produces 375 horsepower (276 kW) and a peak torque of 1800 N·m, available at a low engine speed of 1000–1400 rpm.
This torque-focused design ensures smooth acceleration, reliable climbing ability, and stable cruising performance on highways and mountainous routes. Supporting Euro IV, Euro V, and Euro VI emission standards, the engine meets multiple international regulatory requirements, making the tractor unit suitable for export markets and regions with strict environmental policies.
Smooth Transmission and Optimized 6×4 Drivetrain
Power is delivered through a Fast 12JSD180TA manual gearbox, featuring 12 forward gears and 2 reverse gears. This transmission allows drivers to precisely match engine speed to road conditions, improving fuel economy and reducing mechanical wear during long-distance operations.
The 6×4 drivetrain configuration, paired with a wheelbase of 3175 + 1350 mm, ensures excellent traction and vehicle stability when hauling heavy trailers. With a maximum speed of 105 km/h, the Delong New M3000 maintains a perfect balance between efficiency and transport productivity.
Durable Axles and Lightweight Chassis Design
The tractor unit is equipped with a MAN 5.5T maintenance-free front axle and an 11.5T MAN single-stage reduction rear axle, offering a combined rear axle load capacity of 18,000 kg (two-axle group). The 4.111 speed ratio further enhances fuel efficiency during highway cruising while maintaining sufficient pulling power for loaded trailers.
Thanks to its lightweight rims, optimized frame structure, and a curb weight of only 8.3 tons, the Delong New M3000 increases payload capacity and reduces overall operating costs—an important advantage for fleet operators focused on efficiency.
Long-Range Fuel Capacity and Practical Configuration
To support extended transport routes, the tractor unit features a 700-liter aluminum alloy fuel tank, providing long driving range while reducing vehicle weight compared to traditional steel tanks. This design minimizes refueling stops and maximizes operational uptime.
Additional practical features include a 50# saddle, 12R22.5 18PR tires (10 pcs), and a 3/5 leaf spring suspension, all contributing to stable trailer coupling, improved load distribution, and enhanced road durability.
Comfortable High-Roof Cab for Long-Haul Drivers
Driver comfort is a key focus of the Delong New M3000. The extended high-roof cab is designed for long-distance operations and includes four-point airbag suspension, effectively reducing vibration and fatigue. The cab accommodates three passengers with a half-row seating layout, making it suitable for team driving and logistics operations requiring flexibility.
Additional highlights such as a maintenance-free 165Ah battery, road-vehicle bumper, and practical interior layout ensure safety, reliability, and convenience throughout daily operations.
