How do I make my Tesla sound like a gas car?
While parked, open this page in the Tesla browser, press Start engine and allow location access. Turn up the media volume and drive: the engine sound follows your speed. Bookmark the page so it is one tap away next time.
Does it play outside the car, like Boombox?
No. eCarSounds plays inside the car through the regular speakers, like music. A web page cannot use the external Boombox speaker.
Why does it need my location?
The engine noise is driven by your speed, and the browser measures speed with GPS. Your location stays in the browser and is never sent anywhere.
Is there a delay in the sound?
A short one. In a Tesla the revs follow your speed about half a second behind, and when you floor it or lift off, the engine responds after about a second. About a quarter of a second of that is the car's own audio system; the rest is because GPS only sees the car speed up after it happens. On a phone, GPS updates once a second, so the sound reacts after about 1.5 to 2 seconds.
Is it a recording of a real engine?
No. Every sound is synthesized live by our own code, so the engine reacts to each change in speed instead of looping a sample.
Does it work in other electric cars?
Yes, in any car with a modern web browser and location access. You can also use it on a phone connected to the car speakers by Bluetooth. Keep the page open: the sound stops when the browser goes to the background.
