Use it in your car

  1. Park. Open this page in the car's browser and press Start engine. Allow location: the speed comes from GPS and never leaves the car.
  2. Turn the media volume up and drive. The revs follow your speed; the gearbox shifts on its own.
  3. At a red light hold Rev to blip the throttle. Standing still you can also try Test drive or Play demo run.
  4. Shape the sound with the sliders: character opens the exhaust, crackle adds pops on lift-off.

Sound lags the speed by roughly half a second in a car browser and by one or two seconds on a phone, because GPS reports speed about once a second.

Compatibility

Tesla browser

Model 3, Y, S, X and Cybertruck. Plays through the car's speakers. Tap Start engine and allow location when asked.

Other EVs

Any car whose browser has Web Audio and location: Polestar, Volvo, Rivian, BYD and most Android Automotive cars.

Phone

Chrome, Edge or Safari with the phone on the car's Bluetooth. Keep the screen on, or the browser pauses the sound.

Sounds

Questions

Is this safe?

Keep the volume sensible: an engine sound can mask sirens and your car's own warnings. You are responsible for driving the car; this page only plays audio.

Why does it need my location?

GPS is the only way a web page can know your speed. The fixes are used for speed and acceleration right in the browser and are not sent anywhere.

Location is blocked. What now?

Tesla: tap the lock icon left of the address, open Site settings, set Location to Allow, then reload. Chrome / Edge: same: lock icon → Site settings → Location. Safari on iPhone: Settings → Privacy → Location Services → Safari Websites → While Using.

How does the free tier work?

You get five minutes of engine time per day on each device, no account needed. EVroar Pro removes the limit for $3/month + tax on up to two devices. Cancel any time; access stays until the end of the paid month.

How do I pay from the car?

Press Unlock. The car shows a QR code; scan it with your phone and pay there with Stripe. The car notices within a few seconds. You can also pay on the device itself.

How do I use Pro on a second device?

On the Pro device press Add another device and you get a six-character code that lives for ten minutes. On the other device press Redeem subscription and type it in.

How do I cancel?

Press Manage subscription on a Pro device. It opens the Stripe billing portal where you can cancel, change the card or download invoices.

The sound stutters or stops

Close other tabs and keep this one in front. On a phone, keep the screen on. If the sound stops after a long drive, press Start engine again.

Does it play outside the car?

No. A web page can only use the cabin speakers, like music. Tesla's Boombox, which uses the outside speaker, takes sound files from a USB drive and is a separate feature of the car.

Does it keep playing when I minimise the browser?

In a Tesla it should: the sound is played as media, so it continues when you swipe the browser away. Opening the mini player or another media source pauses it. If it stops, open the page again and press Start engine. On a phone, keep the screen on.

Is this affiliated with Tesla or any carmaker?

No. Car names are used only to describe what the sounds resemble. Every sound is synthesized live in the browser; nothing is recorded from a real car.
