Dual-Structured Engine Compartment Double wall structure between engine room and passenger space perfectly intercepts the noise flowed in indoor, and prevents electronic equipment from being damaged by excessive heat of the engine.   Driving Noise Blockage The noise of the wind is perfectly blocked by treatment of double or fourfold sealing at the upper of the door and opening part of the door in the frame respectively. And also, it attained the perfect stillness by applying sealing, wax-application, aseismatic materials, and sound-absorbing materials and sound insulator to all possible parts that vibration and noise may get in through.   Noise Blockade Glass The special film called acoustic PVB that blocks vibration from being transmitted is attached inside the windshield glass in order to reduce the noise occurred while driving more than ever.   Exhaust System Noise Prevention The structure of the exhaust system is optimized by strengthening the hardness of a muffler and reinforcing inside with the high quality sound-absorption materials.   Pre-Silence An air inhalation system of large capacity is installed in front of an air inhalation inlet radiator (pre-silence) in order to reduce the noise occured in the inhalation of air.   High-Precision Drive-In High-Precision Drive-In It reduces noises and also minimizes power loss by aligning the line of propeller shaft and drive shaft that is connected to transmission and acceleration in a nearly straight line(0.5¡Æ).
