The test drive reacts instantly. On the road, GPS and the car's audio add a short delay.
Intensity controls how eagerly acceleration turns into throttle and how late it shifts. Character goes from a stock, muffled engine to a lumpy cam with open pipes and crackle. Crackle sets how much the exhaust pops and the engine misfires; 0% is a clean-running engine.
Test drive lets you hear the car without moving: press the Gas and Brake pedals (lower on the pedal presses harder; the top of Gas holds your speed), or play the demo run.
Location stays in this browser: it is only used to measure speed and is never sent anywhere.
TeslaSound gives Tesla cars, and other electric cars, an engine or motor sound that follows your driving. Pick a gasoline engine that burbles at idle, revs as you accelerate, shifts gears and crackles when you lift off. Or pick an electric buzz, a made-up car that no factory ever built, or a new sound as we add more. Open teslasound.io in the Tesla browser and it plays live through the car speakers. No app to install, no account, no audio files.
Most fake engine noise just loops a recording. TeslaSound builds the sound in real time from your GPS speed. For the engines it models the firing order, exhaust pulses, intake roar and gearbox, so the revs follow what the car is really doing. The electric sound follows the motor speed and fades to a near-silent hum when you lift off and regenerate.
It runs in the browser of current Tesla models (Model 3, Model Y, Model S, Model X and Cybertruck) and in other EVs with a modern web browser. The Compatibility list above shows whether your browser supports it.
More cars are on the way, both real and made-up. Tune each engine with Intensity, Character and Crackle, from a stock, muffled engine to open pipes with pops and bangs. On an electric car, Character makes the buzz grittier and brighter.
While parked, open teslasound.io 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.
No. TeslaSound plays inside the car through the regular speakers, like music. A web page cannot use the external Boombox speaker.
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.
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.
No. Every sound is synthesized live by our own code, so the engine reacts to each change in speed instead of looping a sample.
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.

TeslaSound needs your location to measure speed. The browser remembers "Never allow", so it has to be switched back on:
Then reload the page and press Start engine again. Or use Test drive without GPS.
