First claim

1 - 18 . (canceled)

19 . A vehicle, comprising:
a frame; a plurality of ground engaging members supporting the frame; an operator area supported by the frame, the operator area including seating and operator controls, a first portion of the plurality of ground engaging members being located forward of the seating and a second portion of the plurality of ground engaging members being located rearward of the seating, the seating including a plurality of seats in a side-by-side arrangement, the first portion of the plurality of ground engaging members including a first ground engaging member including a first wheel and a first tire and a second ground engaging member including a second wheel and a second tire, the second portion of the plurality of ground engaging members including a third ground engaging member including a third wheel and a third tire and a fourth ground engaging member including a fourth wheel and a fourth tire; a power source supported by the frame and operatively coupled to at least one of the first portion of the plurality of ground engaging members and to at least one of the second portion of the plurality of ground engaging members to propel the vehicle; a cargo carrying portion supported by the frame and located rearward of the operator area, the cargo carrying portion being positioned higher than the power source; a CVT unit supported by the frame and operatively coupled between the power source and the at least one of the plurality of ground engaging members; a first air intake system operatively coupled to the power source to communicate ambient air to the power source, the first air intake system including a first air inlet through which ambient air enters the first air intake system, the first air inlet extending longitudinally along a first longitudinal side of the vehicle, the first air inlet being completely positioned to a first side of the CVT unit; and a second air intake system operatively coupled to the CVT unit to communicate ambient air to an interior of the CVT unit, the second air intake system including a second air inlet through which ambient air enters the second air intake system, the second air inlet extending longitudinally along a second longitudinal side of the vehicle, the second longitudinal side of the vehicle being opposite the first longitudinal side of the vehicle, the second air inlet being completely positioned to a second side of the CVT unit, the first air inlet and the second air inlet are positioned completely rearward of a forwardmost extent of the seating of the operator area.

20 . The vehicle of claim 19 , wherein the first air inlet and the second air inlet are positioned completely rearward of the seating of the operator area.

21 . The vehicle of clam 20 , wherein the first air inlet and the second air inlet are positioned completely rearward of the operator area.

22 . The vehicle of clam 20 , wherein the first air inlet and the second air inlet are positioned completely higher than the plurality of ground engaging members.

23 . The vehicle of clam 22 , wherein the first air inlet and the second air inlet are positioned completely higher than a floor of the cargo carrying portion.

24 . The vehicle of clam 23 , wherein the floor of the cargo carrying portion extends over the power source, the cargo carrying portion further including a plurality of walls extending upward from the floor.

25 . The vehicle of clam 20 , wherein the first air inlet and the second air inlet are positioned laterally outside of a lateral extent of the power source and the CVT unit.

26 . The vehicle of clam 20 , further comprising:
a first cover including a plurality of openings to permit the ambient air to pass through the first cover, the plurality of openings being the first air inlet; a first filter housing positioned behind the first cover; and a first filter removably positioned within the first filter housing.

27 . The vehicle of claim 20 , wherein the power source is an internal combustion engine, the power source is operatively coupled to the first ground engaging member of the first portion of the plurality of ground engaging members through a first half shaft, operatively coupled to the second ground engaging member of the first portion of the plurality of ground engaging members through a second half shaft, operatively coupled to the third ground engaging member of the second portion of the plurality of ground engaging members through a third half shaft, and operatively coupled the fourth ground engaging member of the second portion of the plurality of ground engaging members through a fourth half shaft, the vehicle further comprising:
a fuel source supported by the frame, the fuel source adapted to provide fuel to the internal combustion engine, the fuel source being positioned between the first portion of the plurality of ground engaging members and the second portion of the plurality of ground engaging members.

28 . The vehicle of claim 27 , wherein a portion of the fuel source is positioned directly below the seating.

29 . The vehicle of claim 27 , further comprising:
a first rear suspension moveably coupling the third ground engaging member to the frame, the first rear suspension including a first suspension arm extending along a longitudinal direction of the vehicle, the first suspension arm having a forward portion rotatably coupled to the frame through a first connection and a rearward portion coupled to the first ground engaging member, the first connection being positioned completely rearward of the forwardmost extent of the seating and completely forward of the third ground engaging member; and a first dampening member having a lower portion and an upper portion, the lower portion of the first dampening member being moveably coupled to the first suspension arm through a second connection positioned completely forward of the third half shaft, the upper portion of the first dampening member being moveably coupled to the frame independent of the first suspension arm through a third connection positioned forward of the second connection, the third connection being positioned lower than the first air inlet; a second rear suspension moveably coupling the fourth ground engaging member to the frame, the second rear suspension including a second suspension arm extending along the longitudinal direction of the vehicle, the second suspension arm having a forward portion rotatably coupled to the frame through a fourth connection and a rearward portion coupled to the second ground engaging member, the fourth connection being positioned completely rearward of the forwardmost extent of the seating and completely forward of the fourth ground engaging member; and a second dampening member having a lower portion and an upper portion, the lower portion of the second dampening member being moveably coupled to the second suspension arm through a fifth connection positioned completely forward of the fourth half shaft, the upper portion of the second dampening member being moveably coupled to the frame independent of the second suspension arm through a sixth connection positioned forward of the fifth connection, the sixth connection being positioned lower than the second air inlet, wherein the first suspension arm of the first rear suspension is moveable relative to the second suspension arm of the second rear suspension.

30 . The vehicle of claim 29 , further comprising a roll cage including a first portion coupled to the frame completely forward of the steering wheel of the operator controls and a second portion coupled to the frame rearward of the seating and completely forward of the first ground eng
