Car manufacturers benefit from an additional year to install devices that allow electric cars to emit low-speed sound.
The lobbying of car manufacturers has worked: they now have until 2020 to install a device on their electric and hybrid cars so that they emit a sound at low speed. The obligation has been claimed for security reasons, in order to avoid as much accidents as possible with the taxes.
The silence of this type of vehicle can indeed deceive the vigilance of a person wishing, for example, to cross a road in an urban environment. The National Highway Traffic Safety Administration estimates that the risk of collision increases by 19% compared to a thermal car. Nevertheless, the future rule is open to debate with regard to future mobility, promised as clean … and silent.
A necessary noise
Manufacturers had to comply with this requirement by 2019. The additional few months granted by the National Highway Traffic Safety Administration should allow them to fine-tune their technology. We think for example of Mercedes, which is particularly close to the music group Linkin Park, or to Nissan, who wants to blackmail his cars.
There is no doubt that this sword of Damocles will eventually serve as an element of differentiation from the competition, and all the more so as freedom should be allowed as to the sounds that future cars will be able to produce (depending on the model or even the choice of the user). In short, there will not be a single sound imposed.
An element of differentiation
On the other hand, the National Highway Traffic Safety Administration refused a request to lower the speed at which the noise will stop. While it is set at 30 km / h, some manufacturers – Nisant in mind – wanted the threshold to be 20 km / h. Nissan has not provided enough evidence to convince decision makers to change.
This will not please Elon Musk, who said in 2013, "It's about making the Model S noisy. For sure, the challenge is also to end the noise pollution. That year, he was talking about a solution in the form of a sensor capable of sending a sound to a person close to the car, rather than a substitute for engine noise as claimed today.
