Mitsubishi Outlander: Power Plant Mount

General Information

For the power plant support, the inertial axis four-point mounting system is utilized, and the system has the following features.

• For the engine and transaxle mountings, the cylindrical liquid seal mountings are used. This reduces idling vibration and acceleration noise, and improves riding comfort.
• For the engine mounting bracket, light weight and high rigidity aluminum is used to reduce acceleration noise.
• For the transaxle mounting bracket, light weight and high rigidity sheet metal is used to reduce gear noise.
• For the front and rear roll stoppers, insulators developed for CVT <2.4L ENGINE> or A/T <3.0L ENGINE> are utilized. This reduces idling vibration and acceleration/deceleration shock.
• A front axle crossmember improves steering ability.
