Domestic leading special SDEC engine of powerul Engineering Edition adopted. Standard 4-valve confgured, with higher intake and exhaust efciency, more intense combustion, powerul, reliable and durable through rounds of optimization and calibration. Adopting straight suspension system, the engine can run stably and reliably. The suspension cushion adopting composite structure can have the serice life prolonged to 100,000km. Through several rounds of optimization, the decoupling rate of powerrain mounting system is over 95% and the shock isolation rate of system is over 80%, on the leading level of China.
