Multiple New Products Unveiled
Another Powerful Addition to the Weichai Gas 4.0 Engine Family
At the event, Weichai officially released the WP3NNG, WP8NG, and WP16NG natural gas engines, underscoring its unrivaled strength in the natural gas-powered commercial vehicle sector.
The WP3NNG4.0 gas engine is Weichai’s first gas engine for light trucks. With a rated power of 140 Ps and a maximum torque of 450 N·m, it outperforms comparable market products in power, fuel economy, and reliability. Featuring a four-valve design and achieving about 8% lower gas consumption under equivalent conditions than competing products, it can, in synergy with OEM partners, achieve a range of over 500 kilometers, meeting the needs of long-haul operations.
The WP8NG4.0 gas engine is developed for cargo trucks, port hauling, and related markets. With a displacement of 8.2 liters, a maximum power of 350 Ps, and a maximum torque of 1,300 N·m, it inherits Weichai’s hallmark of high reliability, adeptly meeting the stringent efficiency requirements of time-sensitive transport sectors such as express delivery and fresh produce logistics.
The WP16NG4.0 gas engine is tailor-made for mountainous southwestern regions where power demands are high. Boasting a displacement of 15.7 liters, a maximum power of 750 Ps, and a maximum torque of 3,400 N·m, it satisfies the needs for high power, high reliability, and top-tier safety in challenging, hilly terrains.
Ultra-Fast, Ultra-Reliable, Driving Toward a Green Future
Weichai Launches New Line of New Energy Commercial Vehicle Batteries
Beyond its continued leadership in traditional powertrains, Weichai is also deeply engaged in the new energy sector. On December 3, Weichai launched its full range of new energy commercial vehicle power batteries for the first time, including battery solutions for heavy-duty and light-duty trucks.
Among the newly released full-range heavy-duty truck batteries, a representative product is the single-pack 100 kWh battery pack. It offers exceptional fast-charging capability—charging from 20% to 80% capacity takes a mere 29 minutes. Utilizing cutting-edge CTP (Cell to Pack) technology, it achieves higher energy density with lighter single-pack weight. Its broad environmental adaptability supports operation at temperatures from -35℃ to 65℃ and charging at -20℃. Through multiple packs in parallel configuration, the battery capacity can be quickly expanded to meet diverse operational ranges, terrains, and application scenarios.
For the light-duty segment, Weichai released a full range of power batteries, prominently featuring a single-pack 140 kWh battery pack. This product supports 2C fast charging, enabling 20% to 80% charge in just 18 minutes. Incorporating pre-lithiation and high-efficiency liquid-cooling equalization technology, the system’s cycle life reaches up to 4,500 times. Employing advanced CTP technology, the single-pack energy density is ≥162 Wh/kg, making it lighter in weight. It can operate in temperatures from -35℃ to 65℃ and supports charging at -20℃.
All Weichai commercial vehicle power batteries adopt blade battery technology, ensuring they remain smoke-free and flame-free even under puncture conditions. Coupled with CTP-enhanced structural integrity and the intelligent management provided by BMS (Battery Management System), Weichai’s new energy battery solutions deliver unparalleled safety and reliability for a greener future.
