The federal government requires automakers to incorporate artificial motor sounds in electric and hybrid vehicles when traveling at low speeds to warn pedestrians, but it wants to allow vehicle owners to choose which sounds they use.
In a Notice of Proposed Ruling, the National Highway Traffic Safety Administration in the United States says drivers should be able to "choose the sound they prefer from the plethora of sounds installed in the vehicle." a link to whether it should limit the number of false sounds that manufacturers should be able to install.
The proposed rulemaking would be an amendment to the rules, finalized in February 201
quieter than their internal combustion engines, ie having colleagues. The only noise that EVs usually generate is caused by wind resistance or tire noises and this is only at moderate to higher speeds.
The new rule requires all newly manufactured electric vehicles weighing 10,000 pounds or less to emit sound when traveling forward or backward at a speed of 19 mph or less. NHTSA says sound signals are not required at higher speeds because other factors, such as wind and wind noise, "provide adequate pedestrian warning." Initially, NHTSA did not foresee what kind of noise manufacturers chose to install in their vehicles.
Some car manufacturers have already chosen their sounds. Mercedes-Benz has an artificial tuning sound selected for its electric EQC range, while VW says its compact ID.3 electric vehicles will be installed with fake low-speed sound when it hits the showroom floor in 2020. Mercedes-AMG , The carmaker's brand, works with rock band Linkin Park to find more bass sound for their cars.
Some automakers are already exploring ways to make money from the lack of noise in EVs. Porsche offers the interior 500 "Electric Sport Sound" in the configurator for the recently introduced Taycan electric sports car, according to Electrek .
However, other automakers are looking for solutions. Last year The Verge reported that Ford needed partial relief for its lineup of police vehicles. The company asks if it could include an "exclusion" – it is suggested that law enforcement officers can use their EVs to sneak at suspected criminals.
