An electric snowmobile that reduces a decrease in charging efficiency is provided. The electric snowmobile includes a body frame, a driver's seat supported by the body frame, an electric motor supported by the body frame, a right ski and a left ski supported by the body frame, a track mechanism including a track belt and supported by the body frame below the driver's seat, a battery that is charged with electric power supplied from an external power source and capable of supplying the electric power to the electric motor, and a battery heater H that can be driven by electric power supplied from an external power source and heats the battery.

A vehicle includes an engine unit, a radiator, a first passage, and a second passage which is provided below the cylinder head and to which lubricating liquid is supplied. The radiator is arranged in front of the engine unit. The first passage includes a first opening arranged in front of the radiator so as to face the radiator and is configured to guide first traveling wind from the first opening toward the radiator. The second passage includes a second opening arranged outside the first opening in the vehicle width while being partitioned from the first opening, and is configured to guide second traveling wind from the second opening toward the lower supplied member.

An electric vehicle includes a frame, a wheel coupled to the frame, and a battery assembly including a housing supported by the frame. The housing includes a top side and a bottom side opposite the top side. A drive assembly of the electric vehicle is at least partially enclosed within a drive housing unit. The drive assembly includes a motor configured to receive power from the battery assembly and a gear assembly configured to transmit torque from the motor to the wheel. The drive housing unit is positioned below the bottom side of the housing.

There is provided a motorcycle which includes an engine including an exhaust port; an exhaust pipe connected to the exhaust port of the engine; and a catalyst disposed within the exhaust pipe. The exhaust pipe includes a catalyst case accommodating the catalyst, and a pipe connecting the exhaust port of the engine and the catalyst case. The catalyst is disposed in front of the engine. An occupied area of the catalyst in a direction orthogonal to a flow direction of exhaust gas is larger than an opening area of the pipe in a direction orthogonal to a flow direction of exhaust gas. A central axis of the catalyst is inclined with respect to a vehicle width direction in a vehicle front view. And the central axis of the catalyst and a center line of the engine in the vehicle width direction intersect at a position overlapping with the catalyst in the vehicle front view.

There is provided a radiator fan configured to introduce outside air into a radiator in front of an engine. The radiator fan includes: a propeller disposed behind the radiator; a fan motor configured to drive the propeller to rotate; and a fan shroud covering the propeller from behind. The fan shroud is formed with a plurality of hoods whose exhaust air ports are directed in any directions in a range from a lateral direction to a downward direction.
