Abstract: A front bumper comprises a lateral end provided with a through duct extending longitudinally along a curvilinear axis with a closed cross-section with respect to the curvilinear axis and defined between an inlet opening facing towards a front of the front bumper, and an outlet opening facing towards an outer side of the front bumper.

Abstract: A motor vehicle includes an engine, an engine compartment, a passenger compartment, a firewall, an interior trim panel, a compartment between the trim panel and the firewall, and a sound conveying duct having an inlet in the engine compartment and extending according to at least one distribution portion along a first axis up to dividing at a division node into at least two disjoint branches extending in the compartment along respective branch axes up to discharging in one or more through-openings of the trim panel with respective divergent portions. The motor vehicle further includes lateral ducts having connecting portions connecting respectively to the branches with a configuration parallel to the divergent portions and extending along respective second axes from the connecting portions up to discharging respectively at second through-openings of the trim panel communicating with the passenger compartment.

Abstract: A motor vehicle comprising a frame defining a cabin, a foldable roof movable relative to said frame and adapted to selectively cover, in use, the cabin at a top thereof and a stowage compartment adapted to contain the foldable roof is disclosed. The motor vehicle further comprises a sensory system adapted to detect a quantity associated with the humidity of the air inside the stowage compartment, signalling means adapted to signal a risk of damage to the foldable roof and an electronic control unit operatively connected to the sensory system and the signalling means. The electronic control unit is programmed to compare the quantity detected by the sensory system with a threshold value and to command the signalling means to signal the risk of damage to the foldable roof, when the quantity detected is greater than the threshold value.

Abstract: A road vehicle having: a passenger compartment delimited by a roof at the top; at least one front seat arranged in the passenger compartment; an accelerator pedal; a brake pedal; a control unit, which implements a launch control procedure; and a manual control, which is can be operated to carry out the activation of the launch control procedure and is arranged on the roof.

Abstract: A hydraulic system of a power transmission has a reservoir, a pump and, downstream of the latter, a junction point, from which a first and a second branch start; the first branch is configured to perform a cooling and/or lubricating function on a part of the transmission; the second branch performs an actuating function by means of a hydraulic actuator; the system further has a first and a second control valve arranged along the first and the second branch, respectively, and are equal to each other; each of them has a first port connected to the junction point, a second port connected to the reservoir, and a third port; the latter, in the first control valve, supplies the part to be cooled/lubricated and, in the second control valve, communicates with a chamber of the hydraulic actuator for pressurizing such chamber.
