Why some car engines have fake Vrooms

This piece of specialized equipment, called 
a Soundaktor, makes a VW sound even better.

Many drivers like to hear the sound of their engines. In fact, some sports cars have special "noise pipes" that allow more of the engine sounds to reach the driver.

However, some automakers have discovered a better way to give you a great "Vroom."

They use "active sound generators", or speakers.

For instance, Volkswagen's GTI has a small device mounted on the firewall near the engine that plays a precorded engine sound.

And BMW's M5 luxury car plays engine noises directly through the car's speakers.

Is this technology a form of false advertising, or is it merely a clever (and cheaper) way to give drivers a better driving experience?

The Rise of the Fake Engine Roar. To make engines sound better, some automakers are broadcasting motor noise through speaker in the cabin. Is this progress—or an affront to the purity of the engine note? Popular Mechanics>>

  3. I don't think it is cheating at all. Little tricks like that have been around for years. The MK5 GTI and GLI had a noise tube that changed the sound of the intake.

    This is just the future of fine tuning the driving experience.

    I did an output test of one it sounds like a spaceship.. I think it's cool
