The utility model provides an engine air inlet cooling system for a vehicle range extender and a vehicle, and belongs to the technical field of vehicles. Wherein the engine comprises a supercharger and an intake manifold, and the engine intake cooling system comprises an intercooler which is connected in series in an electric drive loop cooling system of the vehicle; engine intake air cooling pipeline, the supercharger is communicated with the air inlet manifold; the engine air inlet cooling pipeline is communicated with the intercooler and penetrates through the intercooler, so that compressed air flowing out of the supercharger is allowed to flow to the air inlet manifold through the engine air inlet cooling pipeline, heat exchange is conducted between the compressed air and liquid in the electric drive loop cooling system in the process that the compressed air flows through the intercooler, and therefore the air flowing to the air inlet manifold is cooled. The utility model furtherprovides a vehicle which comprises the engine air inlet cooling system. The engine air inlet cooling system can effectively reduce the occupation of the engine air inlet cooling system on the arrangement space of the whole vehicle.
