Audi has announced that its approach to artificial noise for EVs will be “new and unusual”.
“The obvious approach would be to work on the basis of the familiar sound of a combustion engine,” the firm has said, but links with the Audi RSQ from the Hollywood film 'I, Robot' have been mentioned by the company.
Audi is the latest manufacturer to work on artificial noise for EVs and the new technology will be implemented as a safety feature to make EVs audible to pedestrians.
Audi acoustics boss Ralf Kunkel says: “We speak of quiet cars when an electric car is driven at a speed between 0 and 25km/h [16mph]." Audi hopes to bridge the audible gap to 16mph, which the company is currently developing for its range of e-tron concepts.
Toyota's Japanese car dealerships have already introduced an 'approaching vehicle audible system', which emits synthesised sound of an electric motor with a pitch that rises and falls with the car's oncoming speed.
