Vehicle with high-strength frame members

A vehicle, comprising:

• a powertrain mounted at a front portion of the vehicle;
• a suspension cross member provided to extend in a vehicle width direction and support a front-wheel suspension;
• and
• an extension frame provided to extend forward, in a vehicle longitudinal direction, from the suspension cross member on an outward side, in the vehicle width direction, of the powertrain,
• wherein said extension frame includes a front-side high strength portion and a rear-side high strength portion which are spaced apart, in the vehicle longitudinal direction, from each other and a low strength portion which is positioned, in the vehicle longitudinal direction, between said front-side high strength portion and said rear-side high strength portion, the low strength portion being configured to have a lower bending strength than each of the front-side and rear-side high strength portions,
• a specified portion of said extension frame which is at least a part of said low strength portion, in the vehicle longitudinal direction, of the extension frame is positioned on the outward side, in the vehicle width direction, of and in front of a part of said powertrain which is located at the same level as said specified portion of the extension frame,
• said low strength portion is formed by a part of said extension frame which is configured to be curved inward in the vehicle width direction,
• a load-reception portion is provided at a front end portion of said extension frame, the load-reception portion being configured to protrude outward, in the vehicle width direction, from the front end portion of the extension frame and receive a collision load in a vehicle frontal collision on the outward side, in the vehicle width direction, of the extension frame, and
• said front-side high strength portion of the extension frame is formed by a structure in which a rear end portion of said extension frame is joined to said suspension cross member in a state where the rear end portion of the extension frame overlaps the suspension cross member in the vehicle longitudinal direction.
