Side-by-side vehicle
A utility vehicle includes a plurality of ground-engaging members, a frame assembly, a cab frame assembly, a front suspension assembly, a rear suspension assembly, a power steering assembly, and a powertrain assembly, all of which may be configured to lower the center of gravity of the vehicle.
1. A utility vehicle, comprising:
a plurality of ground engaging members; a frame assembly supported by the ground engaging members; and
a powertrain assembly supported by the frame assembly and including:
an engine;
a continuously variable transmission operably coupled to the engine; an air intake assembly fluidly coupled to the engine; and
an exhaust assembly fluidly coupled to the engine, the exhaust assembly being configured to selectively regulate a flow of exhaust between a high-flow mode and a low-flow mode.
2. The utility vehicle of claim 1 , wherein the exhaust assembly includes a first exhaust body, a second exhaust body, an inlet tube, an outlet tube, a first tube, a second tube, and a valve assembly.
3. The utility vehicle of claim 2 , wherein the first tube is fluidly coupled to the outlet tube and is configured to provide an unrestricted flow path for the exhaust between the inlet tube and the outlet tube.
4. The utility vehicle of claim 3 , wherein the second tube is positioned adjacent the first tube and is fluidly coupled to the first exhaust body and the second exhaust body.
5. The utility vehicle of claim 4 , wherein flow of exhaust through the second tube and the second exhaust body is restricted.
6. The utility vehicle of claim 5 , wherein the second exhaust body includes a plurality of baffle plates.
7. The utility vehicle of claim 6 , wherein the exhaust assembly further includes a solenoid, wherein the solenoid is operable to open valve to allow a substantial portion or all of the exhaust entering first exhaust body from inlet tube to flow into first tube and into outlet tube through an unrestricted path.
8. The utility vehicle of claim 7 , wherein the exhaust assembly further includes a electronic controller unit operable to provide instruction to the solenoid.
9. The utility vehicle of claim 7 , wherein the solenoid is operable to receive a signal to at least partially close the valve to restrict exhaust entering the first exhaust body from the inlet tube to flow into the first tube and the outlet tube such that at least a substantial portion of the exhaust entering the first exhaust body from the inlet tube is diverted to the second tube and through a restricted flow path in the second exhaust body.
10. The utility vehicle of claim 1 , wherein the exhaust assembly is be configured to allow the operator to selectively engage the low-flow mode.
11. The utility vehicle of claim 1 , wherein the exhaust assembly includes an electronic control unit configured to operate the exhaust assembly in the low-flow mode, at specific throttle positions, or when in the non-sport drive mode.
12. The utility vehicle of claim 1 , wherein a sound emanating from the exhaust assembly is greater when in the high-flow mode than in the low-flow mode.
