Nissan introduces its new electric car at Tokyo Motor show 2017. The car will be travel around 373 miles on a single charge. When you drive the car you do not hear engine noise. Which is pleasant for the passenger but maybe its cause of concern in regards to safety. The US Department of Transportation (DTT) has recently decided that all hybrid and electric vehicles should make a noise to protect pedestrians, especially those who have the blind or limited viewpoint. So Nissan calls the feature Canto—literally, “I sing” in Italian and it is designed to warn pedestrians that a very quiet electric car is coming, even at low speeds. Depending on the market requirements, this sound is activated at the speed of 20 to 30 kilometers.
