What is the normal Landwind X7 engine noise?

Clacking sound. The car engine should not make any grinding noise during the engine starting process and the engine sound should be uniform and rapid. There may be a clicking noise when starting a cold car. The sound becomes weaker and disappears once the engine warms up. This is a normal engine noise. As you lightly press the accelerator, let the engine speed increase slowly. During the process, the motor runs smoothly and quietly. Quickly press the gas pedal and the sound of the engine increasing power should be smooth and gentle. Only if there is no metallic knocking sound is it considered a normal sound.
