Adaptable without boundaries, with unparalleled strength! Sunlong Commercial Vehicles Conquer Global Complex Environments with Innovative Technologies

Date of issue:2025-08-21 Source:本站

In July in Shanghai, the plum rain is continuous, and the air is filled with a humid atmosphere. On the production line of Shanghai Sunlong Bus Co., Ltd., it is another bustling scene. In the workshop, semi-finished buses exported overseas are arranged in an orderly manner, waiting for the final assembly and debugging. In order to complete a large number of orders on time, the workshop production team has adopted a big work mode, working overtime and racing against time to ensure that every car can be delivered to customers with the highest quality.

In the first half of 2025, Sunlong Automobile's overseas market performance will be strong, with a year-on-year increase of 70% in export delivery, and multiple large cooperation orders won in the Americas, Middle East, Southeast Asia and other places. Behind this impressive performance report is the result of Sunlong Automobile's deep cultivation of localized adaptation strategies - tailored technical solutions for different regions' climates, terrains, and usage scenarios, breaking through environmental limitations with innovative technologies, providing commercial vehicle solutions that meet the needs of global users, and increasing Sunlong's influence in the international market.

High temperature and humidity fearless, heat dissipation and rust prevention double protection

In Southeast Asia, a tropical region with high temperatures and heavy rainfall throughout the year, air humidity often exceeding 80%, and severe salt erosion in coastal areas, Sunlong Commercial Vehicles has precisely anchored environmental pain points and built a comprehensive and multi-level adaptation plan. In order to crack the "baking test" of high temperature on the vehicle power system, Sunlong has carried out a disruptive upgrade to the cooling system. A new turbocharged intercooler system has been added, which can reduce the intake temperature in a short period of time through an efficient air cooling device, ensuring that the engine can maintain stable power output and fuel economy even in extreme high temperatures above 40 ℃.

Faced with the ubiquitous threat of salt spray corrosion in tropical coastal areas, Sunlong adopts a "dual armor" strategy in chassis protection. Firstly, cathodic electrophoresis technology is used to form a dense electrophoretic paint film on the surface of the chassis metal; On this basis, partial PVC coating is sprayed on key parts of the chassis, which has a salt spray resistance time of up to 1000 hours, far exceeding industry standards.

Flood control challenges calmly, ensuring stable and far-reaching waterproofing and travel protection

In global flood prone areas, floods ravage and stagnant water accumulates for a long time, posing a severe challenge to vehicles due to the water flow carrying sediment. Sunlong deeply analyzes the complex working conditions in flood prone areas and creates professional level adaptation solutions through systematic technological innovation, laying a solid safety defense line for water crossing.

In response to the common scenario of deep water flooding in flood prone areas, Sunlong has innovatively designed the chassis architecture to lift the minimum ground clearance of the carriage chassis to ≥ 40cm, ensuring that core power components such as the engine and gearbox are steadily higher than the conventional water wading line. At the same time, in terms of waterproof protection, Sunlong has built a comprehensive "waterproof fortress": high-voltage wire harness connectors have reached IP68 level and can withstand long-term underwater work; The motor controller and battery pack have IP67 protection capability, and can maintain normal operation even after soaking in 1 meter of water for 30 minutes; The low-voltage electrical plug reaches IP65 rating and can withstand the impact of strong water jets.

In addition, the perforation of the entire vehicle harness adopts a dual sealing process of "double-layer rubber parts+high-strength sealant". The electrical interfaces below the water line are not only equipped with streamlined waterproof bends and high-strength waterproof covers, but also matched with IP55 protective junction boxes to form multiple protective barriers.

In a professional water test field, the vehicle continuously passes through a 40cm deep flooded road section, and the electrical system and powertrain operate stably throughout the entire process. The actual application data is even more remarkable. In the flood prone areas of Southeast Asia, the Sunlong commercial vehicle using this adaptation scheme has reduced the rainy season failure rate by 76%.

With this comprehensive set of extreme weather and various terrain adaptation solutions, Sunlong commercial vehicles have not only successfully overcome the difficulties of driving in high-altitude, high-temperature, and various terrain areas, but also won market reputation with reliable quality. In the future, Sunlong Commercial Vehicles will continue to deepen its technological innovation, bringing better and more efficient travel solutions to global users, and further consolidating its industry position in the international commercial vehicle market.
