2. The vehicle of claim 1, wherein the CVT unit includes a housing having a base portion and a cover and the inlet in the portion of the plurality of exterior body panels is in fluid communication with an interior of the CVT unit through an opening in an interior wall of the base portion of the housing of the CVT unit.

3. The vehicle of claim 2, further comprising

a cover supported by the plurality of ground engaging members to cover the inlet in the portion of the plurality of exterior body panels, the cover including a plurality of openings to permit the ambient air to pass through the cover;

a filter housing positioned behind the cover; and

a filter removably positioned within the filter housing, the ambient air passing through the filter.

4. The vehicle of claim 3, further comprising a first suspension system coupled to the frame and to the second ground engaging, the first suspension system including a first movable arm rotatably coupled to the frame, the inlet in the portion of the plurality of exterior body panels being positioned completely above the first moveable arm of the first suspension system.

5. The vehicle of claim 4, wherein the inlet in the portion of the plurality of exterior body panels is located higher the first wheel, lower than an upper extreme of the seating, rearward of a front extreme of the seating, and forward of the second wheel.

6. The vehicle of claim 1, wherein the inlet in the portion of the plurality of exterior body panels is located higher the first wheel, lower than an upper extreme of the seating, rearward of a front extreme of the seating, and forward of the second wheel.

7. The vehicle of claim 6, wherein the inlet in the portion of the plurality of exterior body panels is positioned within a lateral extent of the vehicle.

8. The vehicle of claim 1, wherein the first ground engaging member is operatively coupled to the power source and the second ground engaging member is operatively coupled to the power source, wherein the CVT unit is positioned rearward of the seating, the CVT unit having a drive member with an axis of rotation transverse to a vertical centerline plane of the vehicle;

and wherein the cargo carrying portion is a cargo bed.

9. The vehicle of claim 1, wherein the power source is an internal combustion engine, the power source being 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 second portion of the plurality of ground engaging members through a second half shaft, and operatively coupled a third ground engaging member of the second portion of the plurality of ground engaging members through a third half shaft, the third ground engaging member including a third wheel and a third tire, 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.

10. The vehicle of claim 9, further comprising:

a second air intake system operatively coupled to the internal combustion engine to communicate ambient air to the internal combustion engine for combustion of the fuel, the second air intake system including a second air inlet in the plurality of exterior body panels through which ambient air enters the second air intake system, the second air intake system includes an airbox located rearward of the drive member of the CVT unit and below the cargo carrying portion, the airbox includes a base portion and a cover, the cover of the airbox is located rearward of the base portion of the airbox, a filter is positioned in an interior of the airbox, the cover is removably coupled to the base portion to permit access to the filter;
