Abstract: A vehicle front section structure includes: a power unit installed at a front section; a left and right pair of front side frames extending in a vehicle front-rear direction; a left and right pair of front side members extending in the vehicle front-rear direction at a vehicle upper side of the left and right pair of front side frames, with rear end portions of the front side members being respectively joined to the left and right pair of front side frames; a cross member disposed at a vehicle rear side and obliquely upward of the power unit so as to span between the left and right pair of front side members and to support a driving seat of the vehicle; and a reinforcement brace spanning between the cross member and at least one front side member of the left front side member or a right front side member.

Abstract: A vehicle front section structure includes left and right front side frame. A deformation portion configured to undergo compression deformation in the vehicle front-rear direction at a time of head-on collision of the vehicle is provided at a front end portion of each of the left and right front side frames. Left and right front side members that support a floor section of a vehicle cabin extend along the vehicle front-rear direction at a vehicle upper side with respect to the left and right front side frames. Front sections of the left and right front side members and the corresponding left and right deformation portions are connected by left and right coupling members.

Abstract: Instrument panel side parts are provided integrally with an instrument panel main body part. Vehicle-mounted components are housed in the instrument panel side parts. Thus, even in a vehicle in which an engine compartment is not provided on a vehicle front side in a vehicle cabin it is possible to ensure a housing space for these vehicle mounting parts. Further, the instrument panel side parts are provided integrally with the instrument panel main body part. Thus, compared to a case in which the instrument panel side parts are separated from the instrument panel main body part, a space around the driver's seat can be expanded by the reduced amount of dead space, and the comfortability of the driver can be ensured.
