II. Core Advantages: 400 Horsepower Power, Demonstrating Core Strength

1. 400 Horsepower Strong Power, Ample Power Reserve

The Howo 4x2 400HP tractor is equipped with Weichai WP10H400E50, WP12.400E201, or Sinotruk MC series 400hp engines. All engines are inline six-cylinder, water-cooled, turbocharged, intercooled, four-stroke direct-injection designs, with displacements ranging from 9.5L to 12L. Maximum output power reaches 294-316kW, and maximum torque reaches 1900-2060N·m. Power output is abundant and stable, reaching maximum torque at 1000-1400rpm. It boasts outstanding starting, climbing, and acceleration capabilities, maintaining efficient operation even under a maximum towing gross weight of 35 tons, easily handling high-intensity demands such as long-distance standard load and engineering equipment towing. The engine, tuned with MAN technology, boasts exceptional fuel adaptability, compatible with various diesel fuel qualities, effectively reducing the risk of malfunctions due to fuel quality issues. It also employs common rail injection technology for complete combustion, balancing fuel economy and environmental friendliness. Emission standards cover multiple specifications, including China V and Euro II, meeting environmental regulations in different regions worldwide. Furthermore, some models offer LNG and CNG natural gas power options, further reducing operating fuel consumption and environmental impact.

2. Lightweight Design, Controllable Operating Costs: The vehicle adopts a platform-based, modular, lightweight design. While ensuring body strength and towing capacity, it extensively utilizes aluminum alloy materials (aluminum alloy fuel tank, aluminum alloy gas storage tank, etc.), combined with MAN technology single-layer frame, fewer leaf springs, tubeless tires, and other lightweight components. The vehicle's curb weight is only 6.8-7.8 tons, giving it an advantage over comparable models with the same horsepower, allowing it to carry more cargo and improve transportation profitability. Meanwhile, the Mercedes-Benz-engineered cab boasts a drag coefficient as low as 0.49, effectively reducing high-speed driving resistance. Combined with the low rolling resistance of tubeless tires, fuel consumption can be reduced by 2-3L per 100km, resulting in significant fuel cost savings over the long term. The vehicle's purchase price is affordable, spare parts are readily available and inexpensive, and basic maintenance can be performed without specialized technicians, significantly reducing initial investment and subsequent operating costs, aligning with users' "low-cost, high-return" operational needs.

3. Robust Chassis, Stable Traction, and Easy Maintenance: Designed specifically for the 400hp power output, the chassis has undergone exclusive optimization, employing a high-strength parallel ladder frame. Some models feature a partial three-layer frame design, resulting in a robust and durable structure that effectively distributes traction pressure and extends chassis lifespan. The front axle uses a VG71 or HF9 series 7-9 ton class axle, with a permissible load of up to 6500 kg. The rear axle is equipped with an MCY12, HC16, or 457 single-stage reduction axle, with a permissible load of 11500 kg and selectable gear ratios of 3.7-4.875. It features an inter-wheel differential lock, significantly improving passability and traction stability, suitable for various complex road conditions including highways, mountain roads, and unpaved surfaces. The chassis suspension system uses leaf spring suspension with selectable 2/4 or 9/12 leaf spring counts, paired with hydraulic telescopic double-acting shock absorbers, providing excellent driving stability, effectively mitigating road bumps, and ensuring safe cargo transportation. The vehicle features highly interchangeable parts and a simple structural design. The cab tilt angle can reach 55°, facilitating the maintenance of components such as the engine and water tank, effectively reducing downtime and maintenance costs.

4. Comfortable Driving Experience and Comprehensive Safety Features: Utilizing the Howo H77L or HW76 series cab, this cab offers a high-roof single sleeper design, accommodating two people. The spacious interior features a rational layout and ample storage space, meeting the rest needs of long-distance drivers. The cab employs a four-point airbag suspension system, paired with an air-suspension seat (some models include heating and ventilation functions), effectively mitigating discomfort from road bumps. The interior is richly equipped, featuring standard automatic air conditioning, power windows, power mirrors (with heating function), electronic central locking, and an MP5 multimedia system. Some models are equipped with cruise control and a stepper motor instrument panel, significantly reducing fatigue during long-distance driving. In terms of safety features, standard equipment includes an imported WABCO ABS anti-lock braking system, dual-circuit air pressure braking, spring energy parking brake, and engine exhaust braking. Combined with a large windshield and multiple rearview mirrors, it reduces blind spots. The cab features an all-steel body with steel plates 20% thicker than similar products, and all safety performance indicators meet European ECE-R29 regulations, providing comprehensive safety protection for the driver.

5. Flexible Configuration, Adaptable to Diverse Scenarios The Howo 4x2 400HP tractor offers a wealth of customized configurations, which can be flexibly adjusted according to the needs of different regions and operating scenarios: the steering system uses ZF 8118 hydraulic power steering or Bosch steering gear, which is easy and convenient to operate, reducing driving intensity; the standard tires are 12R22.5 18PR radial tires, a total of 6 tires (including 1 spare tire), and 315/80R22.5 tubeless tires or mixed tread tires can be selected according to needs to adapt to different road conditions; the fuel tank is a 400L aluminum alloy tank, which can be upgraded for long-distance transportation needs, providing sufficient range and reducing the frequency of refueling. Meanwhile, the vehicle is compatible with both left-hand drive and right-hand drive modes to meet the travel needs of different countries and regions. The saddle is compatible with 2-inch or 3.5-inch sizes, and it is compatible with various trailer types such as flatbed trailers, tank trailers, and container trailers. It is widely applicable to diverse scenarios including long-distance standard-load logistics, coal transportation, engineering equipment traction, and port transshipment, and is suitable for domestic provincial highways, expressways, and complex overseas road conditions.
