Whether you are a fleet operator or an owner-operator, this Dayun Truck Review covers everything you need to know.
Dayun V9 – the flagship heavy truck engineered for long-haul excellence and driver comfort.
The Dayun V9 is the crown jewel of the lineup. Launched in 2015 after four years of rigorous R&D, the V9 is positioned as a domestic high-end heavy truck, purpose-built for high-value freight: cold chain, express logistics, hazardous materials, and industrial goods. Its cab — often compared to European benchmarks — offers exceptional space. Internal width reaches ~235 cm, length from windshield to rear wall is 206 cm, and height from floor to ceiling is 200 cm. The lower sleeper measures 220×84 cm, rivaling top-tier European cabs.
Engine: Weichai WP13 series, up to 550 hp and 2550 N·m torque. Optional WP12.460E50 (460 hp, 2110 N·m).
Transmission: 16-speed Fast Gear, rated for 2600 N·m, based on American Eaton technology.
Fuel tanks: 400+600 L diesel + 80 L AdBlue. LNG versions offer up to 1500 L gas capacity, range up to 1800 km.
Active safety: TPMS, LDWS, FCW, EBS+ESC, AEBS, EPB.
Dayun trucks are powered predominantly by Weichai engines — the backbone of Chinese heavy-duty mobility. The N8V series offers fuel power from 350 to 500 hp, while gas variants span 350–460 hp. All models feature high-horsepower engines paired with overdrive gearboxes and small-ratio rear axles, delivering outstanding transmission efficiency.
Gas-powered Dayun trucks — such as the CGC 4180 LNG and CGC 4250 6×4 — are engineered for both economy and environmental responsibility. With dual 450 L tanks for LNG or eight 130 L cylinders for CNG, range reaches up to 1200 km per fill. Operators report that the combination of Weichai gas engines and Fast Gear transmissions delivers smooth, vibration-free performance even under heavy loads.
Safety is non-negotiable in heavy transport, and Dayun equips its trucks with comprehensive active and passive systems. The V9 features a dual-circuit braking system that ensures effective stopping power even if one circuit fails. Engine-assisted braking, ABS, and high-friction brake shoes provide confident descent control on long grades.
Durability is equally impressive. Some Dayun CGC4250 units have logged over 400,000 km in two years, with robust frame and leaf-spring suspension designed for extreme loads. One owner reported 700,000 km over six years with only routine maintenance — no major breakdowns. The N8V’s cab features double-seal design, sound insulation, and idle noise under 60 dB, creating a quiet, durable workspace.

Long-haul drivers spend countless hours on the road, and Dayun prioritizes their well-being. The V9 cab offers a nearly flat floor with a tunnel rise of only 8 cm, maximizing usable space. The upper bunk measures 190×72 cm, while the lower bunk is a generous 220×84 cm — comparable to top European models.
The N8V series takes comfort further with four-point cab suspension, reducing lateral vibration and improving ride quality. Sound-insulating materials and PVC+polyurethane foam flooring keep interior noise below 60 dB at idle. These features make Dayun trucks a genuine “mobile home” for professional drivers.

12-inch LCD instrument cluster, start-stop button, central locking, rain/light sensors, ambient LED lighting, and autonomous cabin heater.
Experienced operators consistently praise Dayun trucks for reliability and cost-efficiency. A fleet manager in Russia noted that Dayun CGC4250 gas trucks delivered “significantly lower operating costs” due to fuel savings, with maintenance intervals extending well beyond expectations. Another owner highlighted that after 510,000 km on a used N8V, the engine, gearbox, and rear axle remained trouble-free.
Some users have noted that parts availability can vary by region, but the growing dealer network and Dayun’s commitment to service are steadily improving after-sales support. Overall, the consensus is clear: Dayun delivers exceptional value for money, with a total cost of ownership that often undercuts European and even some Chinese rivals.
Dayun’s portfolio covers virtually every heavy-truck application. Below is a snapshot of the core series:
| Series | Type | Power | Key Use |
|---|---|---|---|
| V9 | Tractor 4×2 / 6×4 | 460–550 hp | High-value freight, cold chain, express |
| N8V | Dump / Tractor 6×4 / 8×4 | 350–500 hp (diesel/gas) | Mining, construction, bulk transport |
| N8E | Lightweight tractor | 430–460 hp | Coal, sand, regional haulage |
| N6 | 4×2 cargo truck | 160–245 hp | Light industrial goods, urban delivery |
The N8V dump truck, for instance, features a U-shaped high-strength steel container, a 750 mm cooling fan, and a 16-ton Mercedes-technology rear axle, making it a favorite in harsh environments. The N6 series, meanwhile, offers a lightweight chassis with Fast Gear transmission and Weichai power, ideal for cost-conscious urban fleets.
Dayun trucks occupy a sweet spot between affordability and premium features. Compared to European brands, Dayun offers comparable cab dimensions and performance at a fraction of the cost. Against domestic Chinese rivals, Dayun often undercuts prices by 10–15% while maintaining robust build quality.
Dayun’s international presence is growing rapidly. The brand has established partnerships across Oceania, Latin America, Africa, Southeast Asia, and Central Asia. At the 135th Canton Fair, Dayun’s V9 and N8V gas trucks drew enthusiastic responses from global buyers, underscoring the brand’s rising reputation.
