Automotive News reports on BMW’s potential plans to add artificial sounds to its electric vehicles to make them safer to pedestrians.

According to the magazine, BMW’s competitors Audi and Mercedes-Benz have already begun developing specific-sounds for their EVs.

BMW is weighing whether to add artificial sounds to its electric vehicles to make them safer to pedestrians. German rivals Audi and Mercedes-Benz say that they already have started developing brand-specific sounds while Nissan and Infiniti have revealed the solutions they will use to ensure that their EVs don’t pose a danger to people when traveling at low speeds.

BMW considers adding artificial sounds to make Electric Vehicles safer

BMW spokesman in charge for the future electric vehicles family, Tobias Hahn, said the BMW and MINI prototype electric cars currently are not equipped with active sound systems that add artificial noise at low speeds.

“However we have been looking into possible technical solutions for a while and we would be able to add such a feature to our vehicles should this turn out to be a real problem. We are also cooperating with organizations for the visibly impaired in Germany.”

In summer of 2011, BMW will roll-out a new field trial, ActiveE, an electric vehicle conversion based on the 1 Series Coupe. Two years after the kick-off of this field trial, BMW will launch their first built-from-the-ground-up electric vehicle, Megacity.

While Mr. Hahn has not offered more details on the technology piece behind the artificial sounds, the competitors have been more open about it. Mercedes is said to deliver a naturally produced sound that warns pedestrians but does not mimic the noise created by an internal combustion engine.

Audi’s acoustics experts are working to create a futuristic engine note for the brand’s EV.

On the other hand, the wonder hit Nissan Leaf emits a noise that can be described as a cross between a small jet plane and a monorail.

With the Megacity vehicle moving forward towards production, we expect BMW to reveal more technical details this year.

        I think Horatiu should add an extra lockout, that when you reach 12 negative votes your comment is deleted completely.

      No, the sound of a little kid making engine noises! Wait, the Jetson car!

    A naturally aspirated I6 noise would be nice :)

    Make it sound like an M6 or don’t bother. How stupid is this idea anyway. You make an electric car to try and decrease consumption and pollution. Now you want to add some noise pollution and have an on going engine sound that consumes energy. Don’t BMW engineers have better things to do??? Like fixing the far from perfect electric steering system that the dumped, making current BMWs steer like a delayed game steering???

      Piezokinetic sound generators would use virtually no energy. You seem very bigoted concerning the sight impaired.

        lol… bigoted?

    Well, I think sounds are necessary because the average pedestrian is rather pre-occupied when walking/crossing the streets while talking on their cell phone or texting at the same time while walking; I’ve seen people literally walk straight into poles. A lot of people still have a chance of waling straight into a moving car with normal “car sounds” let alone a car with no sound; that’s a disaster waiting to happen.

    I feel sorry for all those who live in mega cities when these electric cars come out. Can you imagine the different noises all combining to give the most horrible road noise imaginable.
