Rombo turns Tesla speed into engine noise
Rombo is a web app for Tesla’s browser that uses GPS speed and a virtual drivetrain to synthesize engine sounds through the car’s speakers.

- Tesla drivers seeking synthesized engine audio
- Worth noticing
- The sound is generated from firing pulses rather than recordings; the page says GPS updates arrive about once per second.
Field notes
The page says the browser reports position about once a second, which Rombo smooths and uses to look slightly ahead. Per-engine torque curves, gear ratios, and shift points drive the virtual automatic behavior, including throttle blips on downshifts; the sound is computed from firing pulses rather than recorded loops. Seven engine and dashboard combinations are listed, including a cross-plane V8, a 1985 V6, and an electric-drive option. Setup instructions say to configure while parked and not touch the screen while driving.
