Silent car.
Loud attitude.

Your EV is quick. Now it sounds the part. Bamsirev turns your speed into a living engine note that revs, shifts and crackles through the cabin speakers, straight from the car's browser.

Pit stop

What do I need to get going?

Just the car's browser. Open the site, tap START, done. Nothing to download and no sign-up.

Where should I use it?

On the track. Bamsirev is made for track days, closed courses and fun while parked. It isn't meant for public roads; if you choose to use it there, it's at your own risk, traffic law comes first, and Launch mode stays off.

Will people on the street hear me?

Only the people in the car. The sound comes out of the cabin speakers along with your music; a website can't reach the car's outside speaker.

How quickly does it react when I floor it?

GPS refreshes about once a second, so Bamsirev predicts what happens in between and smooths the revs. Hard launches feel a touch behind; normal driving feels natural.

Why does it want my location?

Speed. That's the only thing it's used for, and it's worked out inside the car's browser. We never get your position. The minimap fetches map images for your area from OpenFreeMap, an open map service, and you can switch it off.

Can I use it in another car or on my phone?

Any Tesla with the browser works, and so do most electric cars with a modern browser. On a phone, connect to the car over Bluetooth and play it from there.

Can I film it for TikTok or Reels?

Please do. Launch mode and the Garage make great clips. Film while parked or let a passenger hold the phone.

Can I stop Pro whenever I want?

Yes. Tap Manage subscription at the bottom of this page, enter the email you paid with, and cancel. You keep Pro until the period you paid for runs out. Lifetime is a one-off payment, so there's nothing to cancel.
