1. A vehicle front section structure, comprising:
a power unit disposed at a front section of a vehicle;
left and right front side frames that extend along a vehicle front-rear direction at respective sides in a vehicle width direction with respect to the power unit, that configure a front section of a frame of the vehicle, that are configured to support the power unit, and that include a lower kick section, the lower kick section sloping with a downward gradient on progression toward a vehicle rear side and formed at a rear section of each of the front side frames;
left and right front side members that extend along the vehicle front-rear direction at a vehicle upper side of the left and right front side frames, that are supported by the left and right front side frames, that configure a part of a vehicle body, and that include an upper kick section, the upper kick section sloping with a downward gradient on progression toward the vehicle rear side and formed at a rear section of each of the front side members;
left and right deformation portions provided at a front section of the left and right front side frames respectively, the deformation portions configured to undergo compression deformation in the vehicle front-rear direction at a time of head-on collision of the vehicle;
a left coupling member connecting the left deformation portion to a front section of the left front side member; and
a right coupling member connecting the right deformation portion to a front section of the right front side member, the right coupling member and the left coupling member are configured so as to more readily undergo plastic deformation under collision load at the time of head-on collision than the left and right front side members.
