    Description: The present invention relates to a vehicle including a spoiler.
    It is known to provide a spoiler on a vehicle to improve the air supply to the engine, especially when the engine is in the rear of the vehicle, which is shown in EP 1 621 451 A2.
    EP 1 621 451 A2 shows a passenger car which has an aerodynamically shaped roof which comprises a roof duct designed as a guide device. The roof channel follows at least in regions extending in the vehicle longitudinal direction roofline and adjacent to a windshield on an inlet device through which air can flow into the roof channel. The tubular body protrude in the inlet area of the roof, so that the air flow can be selectively guided to the inlet area, whereby a storage space is formed. In order to form this storage space, it is necessary to deviate from the streamline shape having the least air resistance, with part of the air flow, namely the air flow, which flows around the inlet area, continuing to contribute to air resistance. It is therefore to be expected that, despite the aerodynamically shaped roof, the drag coefficient will be worsened or at least not improved by the additional function.
    Therefore, there is a need for a solution for improving the coefficient of drag of a vehicle including a spoiler.
    The object of the invention is to provide a vehicle which includes a spoiler, which is aerodynamically optimized so that the drag coefficient can be reduced by the spoiler.
    The object of the invention is achieved by a vehicle comprising a spoiler device according to claim 1. Advantageous variants of the vehicle are the subject of claims 2 to 10.
    When the term "for example" is used in the following description, this term refers to embodiments and / or embodiments, which is not necessarily to be understood as a more preferred application of the teachings of the invention. Similarly, the terms "preferred," "preferred," are understood to refer to an example of a variety of embodiments and / or embodiments, which is not necessarily to be understood as a preferred application of the teachings of the invention. Accordingly, the terms "for example," "preferred," or "preferred," may refer to a plurality of embodiments and / or embodiments.
    The following detailed description includes various embodiments of the inventive vehicle containing the spoiler. The description of a particular vehicle is to be considered as exemplary only. In the description and claims, the terms "include," "include," "comprise," as "included," but not limited to, are interpreted.
    The object of the invention is achieved in that by means of the vehicle, which includes a spoiler, the drag coefficient is reduced by the air deflector is arranged on the vehicle such that the impinging on the vehicle front air is introduced into the spoiler when the vehicle moves forward.
    The vehicle includes a spoiler. The vehicle includes a front area, a windshield, a roof, a rear window and a rear area, which are arranged around a passenger compartment. The spoiler device comprises a channel arrangement. The channel arrangement extends outside the windshield on the roof outside the rear window to the rear of the vehicle. The channel assembly includes an air inlet.
    In particular, the air inlet can be arranged such that air flowing from the front area to the air inlet can be introduced through the air inlet into the channel arrangement. The air inlet may include an opening that is smaller in width than the width of the windshield.
    According to one embodiment, the air inlet is formed as an opening whose dimension in the direction of the vehicle width is at least 10 centimeters, preferably at least 15 centimeters. The opening may have a dimension in the direction of the vehicle height, which is at least 1 centimeter, preferably at least 5 centimeters. The air inlet may be axially symmetrical with respect to the longitudinal axis of the vehicle. While driving the air is introduced through the air inlet in the channel assembly. Due to the channel arrangement, the air is forcibly guided.
    The channel assembly may include a first channel portion disposed below the windshield. The channel assembly may include a second channel portion that connects downstream to the first channel portion that extends along a side edge of the windshield. The channel assembly may include a third channel portion that connects downstream to the second channel portion that extends along the roof towards the rear window.

    The channel arrangement according to one of the preceding embodiments may include a tube. In particular, the channel arrangement may be formed as a tube.
    The air, which is guided from the front area in the direction of the windshield, is thus derived before hitting the windshield by being introduced into the channel arrangement and is forcibly guided there. Experiments have shown that the discharge of air can reduce or avoid vortex formation at the front-windshield transition, resulting in an unexpected reduction in the drag coefficient.
    The vehicle according to one of the embodiments described above is preferably used as a passenger car.
