Sound - or the lack of it - from an electric car is a factor drivers have reportedly found strange when making the move to an EV.
There is also perceived to be potential risk to pedestrians, especially those with reduced sight. Experts believe that compared to petrol and diesel cars, electric models are 37 to 57 percent more likely to cause low speed accidents with pedestrian and cyclists.
This July, EU law will demand that all new electric cars must be fitted with Acoustic Vehicle Alerting Systems that emit a continuous noise when moving at 20km per hour (12.4mph) or slower to alert pedestrians.
Which is why by tuning the sound manufacturers see an opportunity to not only make electric cars safer, but also to give the car a true expression of the driver’s personality.
BMW so far top the car sound charts having hired top Hollywood composer Hans Zimmer, whose many hits scores include the music for The Lion King and Interstellar. He will produce the sound track for their electric i4 model that goes on sale later this year.
Zimmer, who has an apartment with a view of the BMW HQ in Munich, says: “What did the world sound like before the internal combustion engine, silence is an expensive commodity now. But we could (with electric) make the driving experience more beautiful.
“There is no limit to the sounds we could make, without engine sounds overwhelming everything. We could have the same customisation that led people to create their own cell-phone ring tones, and make a car a more true expression of their personality.”
The BMW i4 will be the first to feature Zimmer's sounds
