Claim:
A power train mounting system, comprising: an engine mount disposed at a first end of a principal axis of inertia of said power train between an engine and a first side member of a vehicle body; a transmission mount disposed at a second end of said principal axis of inertia of said power train between a transmission and a second side member of the vehicle body; a front mount disposed at a front end of said power train between a sub-frame and said power train; and a rear mount disposed at a rear end of said power train between a sub-frame and said power train; wherein installation heights and spring constants of said front mount, said rear mount, said engine mount, and said transmission mount are predetermined such that a majority of an overall weight of said power train is supported by said front mount and said rear mount; wherein a spring constant of said transmission mount in an anteroposterior direction of the vehicle is at least about 1.2 times a spring constant of said transmission mount in a vertical direction, and a spring constant of said transmission mount in a lateral direction of the vehicle is at most about 0.5 times the spring constant of said transmission mount in the vertical direction.
