What Causes the Buzzing Sound After Parking a Tesla?
1 Answers
Tesla's buzzing sound after parking is caused by: 1. The noise comes from the air conditioning fan rotation. Like traditional vehicles, Tesla also has a radiator and coolant system to cool the battery and motor. The working air conditioning compressor and fan rotation produce this sound, similar to how combustion engine vehicles' fans continue running after parking. 2. It's the vehicle's pedestrian warning sound, primarily designed to alert nearby pedestrians during reversing without needing to honk. Taking the Model 3 2021 Standard Range Rear-Wheel Drive version as an example: Its dimensions are 4694mm (length) × 1850mm (width) × 1443mm (height), with a wheelbase of 2875mm. It features an electric vehicle single-speed transmission and reaches a top speed of 225 km/h.
