It isn’t unknown for parents to take sleep-resistant babies for a spin in the car. The constant noise of the engine works as white noise, helping put the kid to sleep. As EVs are too quiet for this, Nissan developed the “world’s first emission-free lullaby”.
The ‘Nissan Leaf Dream Drive’ contains five three-minute tracks available for download. The soundtrack combines sounds of the Nissan Leaf with frequencies of a combustion engine to create a “hypnotic soundscape” for babies.
