HOWO 371 vs HOWO NX: Which Should You Choose?

It’s a common point of confusion: Both the HOWO 371 and the HOWO NX utilize the exact same WD615 371hp engine. Since the "heart" is identical, why pay more for the NX? Here is how to choose between these two heavy-duty titans when the horsepower is the same.

1. Same Engine, Different Chassis Efficiency

While both trucks rely on the legendary WD615.47 engine for its durability and ease of repair, the way they carry that engine differs.

• HOWO 371: Built with a traditional, heavy-duty steel frame. It is designed for "brute force." If you are working in extreme off-road conditions where the truck frame takes a beating every day, the 371's rigidity is a safety net.
• HOWO NX: Features a lightweight chassis design. By using high-strength alloys and optimized suspension components, the NX is lighter than the 371. Since they have the same engine power, the NX boasts a better power-to-weight ratio, leading to better fuel economy and higher legal payload capacity.

2. Cabin Evolution: HW76 vs. NX Platform

The most significant difference lies in the driver's experience.

• HOWO 371: Uses the classic HW76 cab. It’s functional and tough but lacks modern comforts. It’s a "workhorse" in the truest sense.
• HOWO NX: Offers a premium upgrade. The NX cab features better soundproofing (NVH), 4-point air suspension, and a much more ergonomic interior. For long-haul shifts, the NX significantly reduces driver fatigue.

3. Transmission & Handling

Even with the same engine, the "feel" of the drive is different:

• The HOWO NX usually comes with an optimized gear-shifting mechanism. Compared to the older 371 models, the gear throws are shorter and smoother, making it easier for drivers to navigate through heavy traffic or hilly terrain.

4. Final Comparison

The Verdict:

• Stick with the HOWO 371 if you operate in the harshest environments (mining, rough construction) where luxury doesn't matter and you want the lowest initial investment.
• Upgrade to the HOWO NX if you want the reliability of the 371 engine but with lower fuel consumption and a much better environment for your drivers. In 2026, the NX is the smarter long-term business investment.
