What is claimed is: 1. An off-road vehicle comprising a frame, a plurality of wheels supporting the frame, at least two seat assemblies disposed side by side on the frame, the seat assemblies being spaced apart from each other to define a space therebetween, an internal combustion engine powering the wheels, at least a portion of at least one of the two seat assemblies overlapping a portion of the engine as viewed from above, wherein the engine is disposed generally adjacent to the seat assemblies, the engine having a front surface generally facing the space with an intake port opening at the front surface. 2. The off-road vehicle as set forth in claim 1, wherein the engine has a portion positioned generally at a rear end of the space, the portion comprising the intake port. 3. The off-road vehicle as set forth in claim 2, additionally comprising an intake system extending generally forwardly from the intake port. 4. The off-road vehicle as set forth in claim 3, wherein the intake system comprises a throttle body, the throttle body comprising a throttle valve, the throttle body being at least partially disposed within the space. 5. The off-road vehicle as set forth in claim 4, wherein the intake system comprises an air intake duct disposed upstream relative to the throttle body, the intake duct generally extending forwardly from the throttle body and a forward portion of the intake duct extending downwardly. 6. The off-road vehicle as set forth in claim 5 additionally comprising a floorboard extending at least forwardly from a base portion of the seat assemblies, the intake duct further comprising a portion that extends forwardly of the seat assemblies at a location generally below a portion of the floorboard. 7. The off-road vehicle as set forth in claim 6, wherein the intake system comprises an air cleaner unit that is connected to the intake duct. 8. The off-road vehicle as set forth in claim 7 additionally comprising a hood covering at least a forward portion of the frame, the air cleaner unit being disposed below the hood. 9. The off-road vehicle as set forth in claim 5, wherein the seat assemblies define a top surface and a forward surface, the intake duct extending generally along the top and forward surfaces. 10. The off-road vehicle as set forth in claim 6, wherein the floorboard comprises an upward projection that defines a tunnel, the intake duct extending within at least a portion of the tunnel. 11. The off-road vehicle as set forth in claim 5, wherein the intake duct comprises an accumulator disposed between the throttle body and the balance of the intake duct, an inner diameter of the accumulator being greater than an inner diameter of the balance of the intake duct. 12. The off-road vehicle as set forth in claim 1, wherein the engine comprises an exhaust port communicating with the combustion chamber, the engine comprising a rear surface and the exhaust port opening through the rear surface. 13. The off-road vehicle as set forth in claim 12 additionally comprising an exhaust system, the exhaust system extending rearward from the exhaust port that opens through the rear surface. 14. The off-road vehicle as set forth in claim 2, wherein the seat assemblies define a rear surface, at least a portion of the engine being disposed forward of the rear surface. 15. The off-road vehicle as set forth in claim 2, wherein the seat assemblies define a top surface, at least a portion of the engine being disposed lower than the top surface. 16. The off-road vehicle as set forth in claim 15, wherein the seat assemblies define a rear surface, at least a portion of the engine being disposed forward of the rear surface. 17. An off-road vehicle comprising a frame, a plurality of wheels supporting the frame, at least two seat assemblies disposed side by side on the frame, the seat assemblies being spaced apart from each other to define a space therebetween, an internal combustion engine powering the wheels, at least a portion of at least one of the two seat assemblies overlapping a portion of the engine as viewed from above, wherein each of the seat assemblies comprises a seat cushion, at least a portion of the internal combustion engine being positioned higher than a bottom of the seat cushion. 18. An off-road vehicle comprising a frame, a plurality of wheels supporting the frame, at least two seat assemblies disposed side by side on the frame, the seat assemblies being spaced apart from each other to define a space therebetween, and an internal combustion engine powering at least one of the plurality of wheels, at least one of the two seat assemblies overlapping a portion of the engine as viewed from above, wherein each of the seat assemblies comprises a seat cushion, at least a portion of the internal combustion engine being positioned higher than a bottom of the seat cushion.
