“An important element of Nissan Intelligent Mobility is how the vehicle integrates with society, and a crucial component of that is sound,” said Nissan electric cars vice president Daniele Schillaci. 

It’s Nissan’s way of adding a distinctive brand ID to how its EVs sound in the city, as well as giving the safety benefit of an audible alert sound for otherwise silent-running EVs. It won’t be too loud or annoying, either: Nissan promises us it will be clearly audible “without being overly disturbing to pedestrians, residents and passengers”.
