A catalytic converter guard for protecting a catalytic converter on a motor vehicle. The catalytic converter guard can include a set of mounting flanges, an input guard plate, an output guard plate, and a bottom plate coupled to the set of mounting flanges and the input and output guard plates. The set of mounting flanges can be configured to be coupled to a set of frame rails of a motor vehicle. The input guard plate can be configured to be positioned adjacent an input of at least one catalytic converter and can include at least one cutout shaped to permit at least one input exhaust pipe to pass therethrough. The output guard plate can be configured to be positioned adjacent an output of the at least one catalytic converter and can include at least one cutout shaped to permit at least one output exhaust pipe to pass therethrough.

A vehicle-body structure includes a floor panel constituting a floor of an occupant space, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a front-rear direction, a cross member extending and intersecting the center frame in a plan view in the occupant space, and a connecting member extending upward from the cross member, having an upper portion fixed to the center frame, and connecting the center frame to the cross member.

A vehicle body structure includes a front floor panel for placing a heel of a pedal operator, a rear floor panel attached to a rear seat, and a middle floor panel extending from the front floor panel to the rear floor panel. The front floor panel and the rear floor panel are positioned higher than the middle floor panel.

An embodiment upper body structure for a vehicle body includes a front body configured to be mounted on a front portion of an under body of the vehicle body, the front body including front side sills respectively disposed at two opposite sides thereof based on a vehicle width direction and center pillars respectively coupled to the front side sills, each of the center pillars including a quadrangular closed cross-section defined by coupling a center pillar outer member and a center pillar inner member and an outer flange portion extending in a forward/rearward direction of the vehicle body.

To sufficiently improve the distortion stiffness of a vehicle body in a case in which no floor tunnel largely bulging upward from a floor panel is provided. A vehicle-body structure includes a floor panel constituting a floor of an occupant space including a seat on which a passenger is to sit, a cross member provided at a rear portion of the floor panel and extending in a vehicle width direction, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a vehicle front-rear direction, and a connecting member connecting the cross member and a rear portion of the center frame.

An embodiment frame joint structure includes a plurality of body members, each body member including a closed section portion having a closed section of a set shape and a flange portion integrally extending from the closed section portion, and a plurality of joints, each joint having a first end coupled to a connection point of a respective one of the body members and a second end coupled to an adjacent joint.

The invention generally relates to an electric vehicle having an electric motor and a pack for storing energy, said vehicle configured having: at least two passenger seats, including a first seat, and a second seat, positioned behind the front seat and configured to face rearward; and the pack having: a lateral module configured to extend perpendicularly to the longitudinal axis of the vehicle between the first seat and the second seat.
