GENERAL DESCRIPTION

M1321000100339

The engine-transaxle mount is of an inertial axis sup-
porting type whose excellent features have already 
been proven in many Mitsubishi vehicles. The inertial 
axis supporting type mount supports the front upper 
part of the engine at the front and the rear upper part 
of the transaxle at the rear. This arrangement effec-
tively suppresses the engine vibration.
