Abstract

A vehicle having one or more guide vanes each disposed at each of a respective front and/or rear quarter of the vehicle for guiding the airflow in the vicinity of an adjacent wheel of the vehicle.

First claim

The invention claimed is:

1. A vehicle comprising one or more rear guide vanes each disposed at each of a respective rear quarter of the vehicle for guiding the airflow in the vicinity of an adjacent rear wheel of the vehicle by at least partially channeling the airflow laterally inwardly to reduce the wake behind the vehicle, wherein each guide vane is movable from a retracted position to a deployed position.

2. A vehicle as claimed in claim 1 , wherein each rear guide vane is displaced laterally and/or undergoes rotation when it moves from said retracted position to said deployed position.

3. A vehicle as claimed in claim 1 wherein each rear guide vane comprises a first outer guide surface that defines an outer surface of the vehicle when the rear guide vane is in said retracted position.

4. A vehicle as claimed in claim 1 wherein each rear guide vane is fixedly mounted to an inner support panel defining a second outer guide surface, the second outer guide surface defining an outer surface of the vehicle when the rear guide vane is in said deployed position.

5. A vehicle as claimed in claim 4 , wherein the offset between each rear guide vane and the associated inner support panel is substantially constant in a longitudinal direction extending towards the rear of the vehicle.

6. A vehicle as claimed in claim 4 , wherein each rear guide vane and the inner panel to which it is mounted form a channel which converges in a longitudinal direction extending towards the rear of the vehicle.

7. A vehicle as claimed in claim 4 , wherein each rear guide vane and the inner panel to which it is mounted form a channel which diverges in a longitudinal direction extending towards the rear of the vehicle.

8. A vehicle as claimed in claim 1 comprising a plurality of wheels, wherein each rear guide vane extends vertically and at least a portion of each rear guide vane is disposed in line with a rear wheel of the plurality of wheels of the vehicle.

9. A vehicle as claimed in claim 8 , wherein there is at least a partial overlap in a vertical direction between each rear guide vane and the associated rear wheel of the vehicle.

10. A vehicle as claimed in claim 1 wherein the vehicle comprises one or more front guide vanes each disposed at a front quarter of the vehicle for guiding airflow along a side of the vehicle, wherein each front guide vane is movable from a retracted position to a deployed position.

11. A vehicle as claimed in claim 1 comprising a control unit configured to move said one or more rear guide vanes from said retracted position to said deployed position when said vehicle is moving.

12. A rear bumper for a vehicle comprising one or more rear guide vanes for guiding the airflow in the vicinity of an adjacent rear wheel of the vehicle by at least partially channeling the airflow laterally inwardly to reduce the wake behind the vehicle, wherein each rear guide vane is movable from a retracted position to a deployed position.

13. A vehicle as claimed in claim 1 , wherein the vehicle comprises a front profiling member adjacent one or more front guide vanes disposed at a front quarter of the vehicle for guiding airflow along a side of the vehicle, wherein each front guide vane is movable from a retracted position to a deployed position, and wherein said front profiling member is movable from a retracted position to a deployed position.

14. A vehicle as claimed in claim 13 , wherein moving said front profiling member to said deployed position directs the incident airflow over an adjacent one of said front guide vanes disposed at a front quarter of the vehicle.

15. A vehicle as claimed in claim 13 , wherein each of the one or more front guide vanes defines in part the first outer guide surface so as to define a substantially continuous exterior surface when the front profiling member and the front guide vane are both in their retracted position wherein the front guide vane is located rearwards of the front profiling member.

16. A vehicle as claimed claim 13 , wherein the front profiling member and the front guide vane at a same front quarter of the vehicle are movable independently of each other.

17. A vehicle as claimed in claim 13 , wherein said inner support panel and said front profiling member align with each other when they are both in their respective deployed positions and/or retracted positions.

18. A vehicle comprising one or more guide vanes each disposed at each of a respective front and/or rear quarter of the vehicle for guiding the airflow in the vicinity of an adjacent wheel of the vehicle by at least partially channeling the airflow, wherein each guide vane is movable from a retracted position to a deployed position, wherein each of the one or more guide vanes comprises a first outer guide surface that defines an outer surface of the vehicle when the guide vane is in said retracted position, wherein each of the one or more guide vanes is fixedly mounted to an inner support panel defining a second outer guide surface, the second outer guide surface defining an outer surface of the vehicle when the guide vane is in said deployed position, and wherein each of the one or more guide vanes is arranged to at least partially overlap, in a vertical direction, a wheel arch of the vehicle.

19. A vehicle as claimed in claim 18 , wherein during deployment into the deployed position the inner support panel moves outboard to locate in an aperture left by the movement of the guide vane out of the aperture.

20. A vehicle as claimed in claim 18 , comprising one or more front profiling members movable between a retracted position and a deployed position wherein moving said one or more front profiling member to said deployed position directs the incident airflow over an adjacent one of said front guide vanes.
