A recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis. 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. A radiator is positioned above the engine. A cover with an access panel is situated between the engine and the passenger seats. The vehicle is suited for rough terrain travel.

A vehicle configuration wherein the center of mass of the vehicle is approximately superimposed upon the passenger and driver centers of mass when seated within the vehicle. An occupant's center of mass can be approximated using a standard center of mass position approximation, or a combination of any number of standard center of mass position approximations. The vehicle's center of mass can be approximately superimposed upon the occupant's center of mass in at least the longitudinal and vertical directions.

A vehicle lower portion structure for a hybrid vehicle has a vehicle drive battery 32 that is mounted on top of the center floor panel 18 and on a vehicle lower side of a rear seat 26, a fuel tank 34 that is formed so as to include a tank main body portion 36 that is disposed on the vehicle lower side of the center floor panel 18 and an in-tunnel extension portion 38A that is disposed inside the floor tunnel 20 and communicates with the tank main body portion 36, and a fuel pump 40 that is provided at a position within the in-tunnel extension portion 38A where the fuel pump 40 is able to be extracted via an extraction hole 20C formed in the floor tunnel 20.

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.

Power systems, heat exchanger systems, electrical regeneration systems and air drag reduction systems for a wheeled vehicle are provided. The systems comprise a vehicle that includes a compressed air system and electrical system. The power and drag reduction system also comprises a plurality of pneumatic motors, one each connected to each wheel, the pneumatic motors using compressed air to drive each wheel. The electrical system supports vehicle braking and regenerates electricity for vehicle batteries. A heat exchanger heats expanding air and is configured to substantially evenly distribute said heated air to the pneumatic motors. Air from a front grill is diverted to impellers that turn electric generators to regenerate power and reduce drag. A drag reducing arrangement blending mirrors with camera into the vehicle body is included as is a plug-in 120-volt trickle charge system and a quick charge (DC) system for battery charging.

A vehicle lower portion structure for a hybrid vehicle has a vehicle drive battery 32 that is mounted on top of the center floor panel 18 and on a vehicle lower side of a rear seat 26, a fuel tank 34 that is formed so as to include a tank main body portion 36 that is disposed on the vehicle lower side of the center floor panel 18 and an in-tunnel extension portion 38A that is disposed inside the floor tunnel 20 and communicates with the tank main body portion 36, and a fuel pump 40 that is provided at a position within the in-tunnel extension portion 38A where the fuel pump 40 is able to be extracted via an extraction hole 20C formed in the floor tunnel 20.

An object is to supply a sufficient amount of air to a fuel cell stack in a fuel cell vehicle when the fuel cell stack is mounted below a floor, the fuel cell stack configured to draw in air through an intake duct and discharge air to the exterior through an exhaust duct. An air introduction surface (26) faces upward or downward in a vehicle upper and lower direction, an intake passage portion (30) of the intake duct (28) extends along the air introduction surface (26) and vertical walls (31, 32) of left and right end portions of the fuel cell stack (11) while a pair of air introduction ports (33, 34) opens in left and right end portions of the intake passage portion (30), and an exhaust passage portion (39) of the exhaust duct (29) extends along an air discharge surface (27) and vertical walls (40, 41) of front and rear end portions of the fuel cell stack (11) while a pair of air discharge ports (42, 43) opens in front and rear end portions of the exhaust passage portion (39).

A vehicle body structure includes a first middle floor unit for a gasoline vehicle and a second middle floor unit for a hybrid vehicle, and the first and second middle floor units are made interchangeable with each other. A front floor unit and a rear floor unit are made shareable by the gasoline vehicle and the hybrid vehicle. That is, the front floor unit and the rear floor unit can be regarded as a platform. Additionally, the second middle floor unit includes a housing, and an IPU is stored in an interior of the housing.
