The utility model provides a low-pressure EGR engine and a vehicle, and relates to the technical field of vehicles. The low-pressure EGR engine comprises a supercharger, an EGR cooler, an air filter, a mixing pipeline and a cooling water pipeline. The supercharger comprises a gas compressor, the output end of the EGR cooler is connected with the mixing pipeline, the air filter is connected with the mixing pipeline, and the mixing pipeline is connected with the gas compressor; and the cooling water pipeline is arranged around the mixing pipeline. A vehicle includes a low pressure EGR engine. The exhaust gas cooled by the EGR cooler and the fresh air filtered by the air filter are mixed in the mixing pipeline, and the mixed gas in the mixing pipeline is cooled through the cooling water pipeline, so that the temperature of the gas entering the gas compressor of the supercharger can be reduced, and the efficiency of the gas compressor of the supercharger can be improved. 本实用新型提供一种低压EGR发动机及车辆，涉及车辆技术领域。低压EGR发动机，包括增
