On February 25th, the ceremony for the roll-off of the 800,000th gas-powered engine of Weichai and the launch of the new generation WP16NG4.0, themed “Ignite the Future, Power the Mountains and Rivers”, was held in Chengdu. Guests including dealers, customer representatives, and media reporters from all over the country jointly witnessed this glorious moment. From product output to ecological construction, Weichai is joining hands with global customers to drive a new revolution in gas power.

The 800,000th Gas-powered Engine of Weichai Rolls Off the Production Line
At the event site, through a video connection, in the presence of all the guests, brand-new Weichai gas-powered engines slowly rolled out of the production workshop. Weichai officially welcomed a milestone moment – the roll-off and delivery of the 800,000th gas-powered engine.

800,000 units is not just a number; it has established Weichai’s unique leading position in the field of gas power. Since 1999, Weichai has embarked on the research and development journey of natural gas engines. Over the past 26 years, it has injected surging power into the development of China’s gas power. In 2015, Weichai’s 1.0 gas-powered product was successfully launched, opening a new chapter in the development of gas power. In 2019, the 2.0 gas-powered product was introduced, which quickly won market favor with its significant technical and performance advantages. In 2022, Weichai’s 3.0 gas-powered product made a strong debut, further breaking through technical bottlenecks, increasing power, and reducing gas consumption, and its leading edge in the industry became more solid. In 2024, a new generation of 4.0 products was launched, leading the industry development once again.
Ten years of grinding a sword. The natural gas engine of Weichai has evolved from version 1.0 to 4.0, with the product iteration cycle getting shorter and the iteration speed getting faster. With its strong scientific research strength and accurate grasp of the terminal market, Weichai’s production has continued to rise, maintaining a continuous leading edge in the gas-powered heavy-duty truck market, with a market share of over 60% and firmly occupying the dominant position.
The Launch of the New Generation WP16NG4.0
At the launch event in Chengdu, the new generation WP16NG4.0 was launched. This engine, known as the “strongest gas power on the earth”, is specially tailored for the Southwest market and is another masterpiece of Weichai’s large-horsepower gas power.

The terrain in the mountainous areas of the Southwest is complex and the road conditions are treacherous, posing higher requirements for the power performance of the whole vehicle, braking safety, and the reliability of the entire engine. At the launch event of the WP16NG4.0, the chief experience officer shared his own usage experience, verifying the product’s strength with visible positive feedback, and redefining the industry ecology together with customers.
The strongest power is defined by extreme working conditions. With excellent performance such as a maximum horsepower of 750Ps, a maximum torque of 3400N·m, and a large displacement of 15.7L, it provides customers with a strong power guarantee. It can start and climb hills with ease, and can handle both highways in plains and those in mountainous areas. Moreover, its power per liter and torque per liter are increased by more than 10% compared with competing products, effectively ensuring the transportation timeliness.
Technical upgrades for gas saving, consumption reduction, and efficient wealth creation. The operating cost has always been the most concerning issue for customers. To reduce gas consumption, Weichai has upgraded both the engine body and the power assembly of the WP16NG4.0 engine. At the engine end, high-efficiency intake technology, high-precision gas distribution technology, and strong tumble flow and fast combustion technology are adopted. At the whole vehicle end, through the optimized matching of the power assembly, the proportion of using high-efficiency gears is increased, and the matching speed is reduced at the same time. The gas consumption of the whole vehicle is reduced by 6%, helping customers create wealth efficiently.

Benchmark technology safeguards safety and reliability. Customers engaged in transportation in mountainous areas have a high demand for braking power. To ensure safety, Weichai has specially developed high-power in-cylinder braking technology. The in-cylinder braking power can reach up to 470kW, reducing the wear and tear of brake pads and tires. At the same time, the product adheres to the concept of lean design, continues the gene of high reliability, and the B10 life can reach 1.8 million kilometers in extreme environments, making truck drivers more at ease in operation.
For gas power, choose Weichai. For large-horsepower gas power, the WP16NG must be the choice. With its outstanding performance of being more powerful, more gas-saving, more efficient, more reliable, and more comfortable, the Weichai WP16NG4.0 is bound to become the best choice for a new generation of truck drivers.
Weichai Launches the One-stop Full-chain Service W-TCO for the Whole Life Cycle
While upgrading product performance and reducing customer costs, at the event site, Weichai announced the launch of the W-TCO model and the establishment of the “W-TCO Club”, which is committed to providing full life cycle cost services and offering customers a one-stop solution covering the whole process from vehicle purchase, vehicle use to maintenance, so as to maximize the operating profit.

Currently, the competition in industries such as commercial vehicles and construction machinery is intensifying. Customers are facing pain points such as great difficulty in identifying product quality, high cost volatility, large differences in service quality, and poor guarantee of service efficiency. There is an urgent need to shift from “single product procurement” to “full life cycle value management”. Weichai gives full play to its advantages in accurate spare parts reserves, pre-positioning of headquarters resources, professional service teams, and standardized pricing. For different service objects such as terminal customers, central warehouses, and maintenance stations, it launches four types of packages including trusteeship business, extended warranty for the whole machine + parts, maintenance packages, and large spare parts packages, aiming to reduce the maintenance costs of customers’ logistics vehicles and mechanical equipment.

After years of development and market verification, adhering to the service concept of “enjoy one-stop full-chain service, ensure cost reduction and efficiency improvement”, Weichai has established a complete TCO service ecosystem. Customers can purchase TCO packages and extended warranty services, and they can enjoy an ultra-long warranty period of 5 years. During the warranty period, they can easily entrust the maintenance. They can enjoy the all-media call platform and the full-coverage service network, and interact with more than 5,000 service stations across the country, and receive high-quality services from “service elites + information staff elites + three-electricity elites”. At the same time, empowered by digital and intelligent technologies, Weichai can achieve high-quality full-chain services, making every kilometer for customers more worry-free and economical.

Ignite the future, power the mountains and rivers. From the “horsepower competition” to the “value revolution”, from a single engine to a service ecosystem, the value of Weichai’s new generation of gas power is still rising. The roll-off of Weichai’s 800,000 gas-powered engines and the launch of the WP16NG4.0 will surely lead the next industry peak.
