EVRoar vs RoarDrive

Your EV is silent. Your heart isn't. EVRoar turns your phone into an engine. Pick a thundering V8, a screaming V10, a turbine-smooth V12, or a cinematic electric drive sound — then drive. EVRoar reads your motion and plays an authentic, gear-shifting engine note through your car's speakers, live. Built for petrolheads who went electric — and anyone who misses the noise. REAL ENGINES, NOT A SOUNDBOARD • Nine distinct engines: cross-plane V8 burble, flat-plane exotic, V10 wail, V12 hypercar, classic muscle, turbo flat-six, vintage oldtimer, exotic supercar, and a futuristic EV synth. • Firing-order accurate — a cross-plane V8 burbles because of its uneven firing pattern, and EVRoar models it. • The sound reacts to load: accelerating sounds different from coasting, with backfires and overrun crackle on lift-off. DRIVEN BY YOUR DRIVING • Uses your phone's GPS, accelerometer and gyroscope to turn real motion into revs. • Simulated automatic gear shifts — feel the shift, hear the bark. • Instant throttle response, tuned for how a real engine loads up. MADE FOR YOUR CAR • Plays through your car's audio over Bluetooth or AirPlay. • Recovers automatically after phone calls and navigation prompts. • Runs in the background with the screen off. MAKE IT YOURS • Configure your vehicle: top speed, number of gears (1–8), and shift style — relaxed, medium or sport. • From a 30 km/h e-bike with 3 gears to a 300 km/h hypercar with 7. • Fine-tune the sensor mix (accelerometer, gyroscope, GPS) and overall sensitivity. TRY IT ANYWHERE • Simulator mode gives you on-screen gas and brake pedals — test every engine from your couch, no driving required. EVRoar is for entertainment. Sound plays inside your own vehicle; you remain responsible for road safety and local regulations. All engine sounds are original, generated audio.

Your car sounds like a race car. RoarDrive plays real engine recordings that follow your actual speed: lift off and it settles, floor it and it climbs, and the gearbox changes where a real one would. It runs on your phone or, better, on your car's own screen: open roardrive.com there and drive. FREE, WITHOUT PAYING ANYTHING • The simulator: drive an engine with two fingers, no car and no GPS needed. • A demo of every engine, a few minutes a day. • The full race dash: rev lights, gear, speed, lap timer with 70+ circuits. THE ENGINE • Recordings of a real engine, not a synthesiser: idle, on-throttle, overrun, the starter, the shutoff, the noise of the pit box while you sit there. • A virtual gearbox with its own ratios, or tell us your car's and it changes where you change. • Launch control: hold the brake for five seconds and the revs sit at the launch point. HOW IT READS YOUR SPEED • The phone's GPS, anywhere, with nothing to set up. • Your car's own browser reads the car's GNSS: faster and tighter. • Coming soon: optional hardware for the best response, a RaceBox at 25 Hz or an OBD-II dongle. NOTHING TO TOUCH WHILE DRIVING You set it up parked. After that the screen is a dash and you just drive. Each engine is bought once and is yours on every screen you sign in on: the phone and the car.
