A vehicle aerodynamic cover includes an upper body portion, a lower body portion and a boundary. The upper body portion defines a top edge. The lower body portion extends downwardly from the upper body portion and defines a bottom edge. The upper body portion is inclined in an inboard direction relative to the lower body portion when the aerodynamic cover is in an installed state. The boundary connects the upper and lower body portions.

A drag reducing device for a motor vehicle having a vehicle body and at least one substantially semi-circular wheel-well for receiving a wheel capable of vertical and rotational movements with regards to the vehicle body, the vehicle comprising unsprung masses associated with the at least one wheel; wherein the drag reducing device comprises a wheel-well cover configured to cover at least a portion of the wheel and of the wheel-well, a pivotal linkage pivotally connecting the wheel-well cover to the vehicle body, and a sliding linkage slidingly connecting the wheel-well cover to an element of the unsprung masses with one degree of freedom oriented in the vertical movement of the at least one wheel.

Disclosed is a salinity detection device. The salinity detection device has a collection plate, a mounting frame, and a sensor portion including a predominantly non-metallic sensor. The device may be mounted in a wheel well of a vehicle via the mounting frame and the collection plate may be attached to the mounting frame and positioned behind a wheel such that water on a road surface may be splashed thereon. The collection plate is fluidically connected to the sensor portion so that water may flow through the sensor portion proximate the sensor to measure a current flowing through the water and determine a salinity thereof.

Resin plate-shaped mudguards 11 are disposed on vehicle width direction outer sides of left and right side members 7 below a cab. A cab rear member 12 is fixed to a vehicle body frame 5 and extends upward from the vehicle body frame 5 to support a rear end side of the cab from below. Mudguard brackets 17 for supporting the left and right mudguards 11 are fixed to an upper end portion of a support member 15L of the cab rear member 12. The mudguard 11 is disposed forward of the mudguard bracket 17 and supported by the mudguard bracket 17. A BSM radar 10 detects information of an object around a vehicle, is disposed on a vehicle width direction outer end portion behind the mudguard 11, and is fixed to a second bracket 19 of the mudguard bracket 17 via a radar bracket 20.
