Looking at the number of Electric Vehicles (EVs) emerging in the market in recent years, it seems like there is no running away from them. A number of EVs, too, have touched down on our shores, such as the Nissan Leaf, Renault Fluence Z.E, and Smart Fortwo Electric Drive. And while their eerily silent nature can be a source of peace and comfort on the go, it can also mean danger to pedestrians and other road users as they might not be known of their presence.

Daimler has 250 people working on the intrinsics of the noises made by their cars. And recently these people have been involved in another spectrum - to produce synthetic noise for EVs. Intial reports have hint at a number of different variants, ranging from 'sonorous purr' to 'sci-fi-like whirr' as 'heard' in the B-Class Electric Drive.

Authorities from around the world, meanwhile, are also busy legislating the use of 'fake noise' for these EVs so as to enhance safety. That said, automakers are likely to work their creativity on this field, such as the Renault Zoe (like the one in this video) that offers a warning system with three selectable tones.
