A lower aerodynamic screen of a front shield of a motor vehicle includes lateral air guides shaped to channel air passing under the aerodynamic screen towards front disc brakes of the vehicle, wherein each air guide is defined by two substantially vertical lateral walls and by an upper wall linked to upper edges of the lateral walls, the air guide being provided, downstream relative to a direction of flow of the air, with a window defined by rear edges of the lateral walls and the upper wall, from which the air emerges towards the disc brakes, the air guide further including a flap that is movable between a position in which it blocks the window and a position in which it is retracted from the window.

A thermal management system and method includes a conduit assembly having a first conduit and a second conduit fluidly separate from the first conduit. The first conduit is fluidly coupled with and extends between a source of a first fluid and a destination for the first fluid. The second conduit directs a second fluid between an inlet and an outlet. The second fluid is configured to exchange heat with the first fluid within the conduit assembly. A control assembly includes one or more control elements that are configured to control an amount of the second fluid that is directed through the second conduit. One or more processors control operation of the control assembly based on one or more of a temperature of the first fluid or a temperature of the second fluid.
