"For this new model, Mitsubishi use a hydraulic engine mounting and alumunium bracket who have a higher rigidity to reduce engine vibration with a light weight construction. The transmission mounting also rebuilt using a lighter bracket made of cast steel.

Extra sound dampening also added in the front of engine area, floor, A Pillar, and dashboard. "
