Defining the FAW JH6 6x4 400HP Tractor Truck
The FAW JH6 6x4 400HP Tractor Truck is a cost-optimized heavy commercial vehicle designed to provide reliable regional transport capabilities through a balance of Weichai engine efficiency and a robust traction system.

Why Select This 400HP Configuration?
FAW Reliability Meets Weichai Efficiency
FAW (First Automotive Works) has engineered this model for fleet owners who prioritize low operating costs. By integrating the Weichai WP10H engine series, this truck achieves a "sweet spot" in performance. It avoids the higher fuel consumption associated with larger 13-liter engines while still providing sufficient power for standard 25-ton to 40-ton loads.
Balanced 400HP Output
The 400 horsepower rating is the industry standard for general cargo and logistics. For routes that are primarily flat or have moderate gradients, 400HP is more than adequate. Choosing this specification prevents "over-specifying" your fleet, ensuring you are not paying for horsepower that your daily operations do not require.
Versatile 6x4 Drive Capability
Even in an economy-focused model, the 6x4 drive layout is retained to ensure safety and operational continuity. The dual rear drive axles provide superior grip on wet tarmac or unpaved logistics yards compared to 4x2 units. ZW Group also offers 4x2 and 6x2 alternatives, but the 6x4 remains the most versatile option for varying road qualities.

Product Features
Weichai WP10H Efficiency
The "H" in WP10H stands for high thermal efficiency. This engine block is lighter than its predecessors and competitors, reducing the overall curb weight of the front end. This weight saving translates directly into better fuel economy figures and allows for a slightly higher effective payload within legal limits.
Premium JH6 Cabin Environment
Despite being an economically positioned model in terms of horsepower, it does not compromise on personnel comfort. The JH6 cabin offers the signature flat-floor design, providing ample room for movement. High-quality sound insulation ensures a quiet environment, which is crucial for reducing fatigue during shifts.
Extended Chassis Design
With a length of 8.445 meters and a wheelbase of 4100+1350mm, this specific tractor configuration offers excellent stability. The longer frame provides better straight-line tracking on highways and allows for versatile coupling positions for different trailer types.

Operational Benefits
Reduced Fuel Expenditure: The 400HP engine consumes less fuel at idle and during light-load cruising compared to 460HP or 480HP variants. For fleets where fuel is the largest variable cost, this model offers the fastest return on investment.
Lower Maintenance Requirements: The WP10H engine and FAW transmission are designed for simplicity and durability. Fewer complex high-performance components mean routine servicing is faster and less expensive, keeping the truck on the road longer.
Enhanced Safety: The combination of a stable 6x4 chassis and excellent visibility from the JH6 cabin creates a safer working environment. The vehicle responds predictably to steering inputs, reducing the likelihood of accidents during maneuvering.

Criteria for Selecting a Supplier
Partnering with the right vendor is essential for a smooth acquisition. Key factors include:
Configuration Knowledge: Can the supplier advise on whether the 4100mm wheelbase suits your trailer length and turning radius requirements?
Spare Parts Ecosystem: Ensure the provider has a robust supply chain for Weichai WP10H specific consumables like filters and belts.
Shipping Versatility: A competent supplier should offer options for dismantling or RORO shipping to optimize freight costs to your port.

Frequently Asked Questions (FAQ)
1. Is the 400HP engine powerful enough for full loads?
For standard legal loads (typically up to 40 tons GCM) on general highways, 400HP is sufficient. It maintains momentum efficiently without the excess fuel burn of larger engines.
2. What does the "Euro 6" standard mean for my operation?
Euro 6 compliance indicates the vehicle uses advanced exhaust after-treatment to drastically reduce NOx and particulate matter. This future-proofs your fleet against stricter environmental zones and regulations.
3. Can ZW Group supply filters and parts for this truck?
Yes, we supply genuine FAW and Weichai parts. We can include a maintenance package with the vehicle shipment to ensure you have essentials for the first few service intervals.
4. How does the 6x4 drive help in rain?
In wet conditions, a 4x2 truck may struggle for grip when starting from a stop with a heavy load. The 6x4 system distributes power across four rear wheels, doubling the traction contact area.
5. What is the typical delivery timeframe?
Once an order is finalized, we typically require 15-20 days for vehicle preparation and port transport. Sea freight duration then depends on the shipping schedule to your specific country.
