A utility vehicle, or UTV, provides a strong, yet lightweight chassis, a set of modular body panels, and various field-serviceability features which enable the UTV to be used in demanding environments such as off-road racing and challenging terrain. An integrated engine and transmission cooler and bodywork vents reduce weight while providing for component cooling while the vehicle is in operation. Passenger/navigator features facilitate use of the vehicle in team-oriented driving, including off-road racing.
