Video: Audi educates us on the R8 E-Tron’s "E-Sound"

One of the biggest allures people have of supercars is the ear-splitting noise these cars produce. After all, nothing speaks to a car’s power than all those ponies working in harmony to produce a roar like no other.

But what happens with a car like the Audi R8 E-Tron, a supercar that’s powered by silent electric motors?

In the case of Audi, it involves a few compromises. In this video, Audi talks about the challenges of producing that emotional sound supercar owners love on a car that’s run by electricity. The solution, as far as Audi engineers are concerned, was to develop a synthetic sound signature that can be played with a loudspeaker attached to the car’s undercarriage.

Take note of the word "synthetic" because that in itself means that the sound is fabricated and not directly derived from the engine. Nevertheless, the objective with the "E-Sound" was to generate enough noise to allow drivers to enjoy the thrills of a supercar with an electric powertrain.

Have they decided to make it mandatory? I’m worried because I don’t really like it.

I do not need to hear it. Actually, I loved it because it is soundless, yet they come up with this?

I’d say the noises of the engines are rather enthralling, but since this is an electric-powered car, installing devices to induce sound impact is just ridiculous.

So, without the speakers, this is thoroughly soundless? Hmmm.. I’d rather prefer it that way anyway. It would help lessen the noise pollution too.

The process they’re going through just to produce an artificial sound is a hassle. And sorry to say, but it’s such a trying hard.
