A recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis that is approximately 50 inches wide. The seats sit low in the chassis and are covered by a roll cage. Grab handles are positioned on the sides of the passenger seat. Select large round tubing protects the vehicle, while rectangular tubing frames the portions of the vehicle beneath body panels. The vehicle is powered by an engine rearward of the seats that is connected to a transaxle. The engine and transaxle are isolation mounted together with a portion of the air intake assembly. The vehicle is suited for rough terrain travel.

A vehicle includes a radiator including a fan, a driving seat provided on a rear side of the radiator, a dashboard disposed on the rear side of the radiator and on a front side of the driving seat, and a heat shield plate disposed between the radiator and the dashboard. According to this structure, it is possible to prevent a device (for example, an electric component disposed on the dashboard) disposed on the rear side of the radiator from directly contacting air that receives heat of the radiator.

A system and method for calibrating and controlling an active dampening system for a chassis of a vehicle having an engine involve operating the engine in a cylinder deactivation mode and, during the cylinder deactivation mode, (i) receiving, from a set of sensors, measured vibrations on first and second frame rails of the chassis, (ii) generating control signals for a set of actuators based on the measured vibration of the first and second frame rails, each actuator being configured to generate a vibrational force in at least one direction, and (iii) outputting, to the set of actuators, the control signals, wherein receipt of the control signals cause the set of actuators to generate vibrational forces that dampen the vibration of the first and second frame rails, respectively, to decrease noise/vibration/harshness (NVH).

An engine mounting assembly includes a front frame element defining, in part, a structural load bearing assembly, a differential case mounted to the frame at a frame mounting area, and an oil pan having upright and bottom walls defining an oil sump. The differential case has an opening configured to receive an axle assembly and has walls defining a pan-receiving recess. The oil pan is configured to conform to the pan-receiving recess to be supported by the differential case and overlap the frame mounting area. The oil pan has a mounting flange extending from the upright walls and mounting bores that receives mounting bolts for coupling the oil pan to the engine and the oil pan to the differential case. The differential case and the oil pan form part of the structural load bearing assembly of the work vehicle to transfer structural loads to and from the front frame element.

A utility vehicle is described having front and rear passenger area, and an HVAC system provides treated air to both front and rear areas. The front area includes a tunnel extending longitudinally rearwardly, and a low profile duct extends within the tunnel to communicate treated air to the rear passenger area. The frame has been modified to mount a drive shaft carrier bearing to maximize the area under the tunnel for hose routing. The frame has been modified to maximize the ingress area for the foot of the rear passenger. The frame has been modified to better seal the vehicle when doors are utilized.
