Every sound is synthesized live and modeled on each engine's layout, firing order, induction and gearbox. Names describe the engines the profiles are modeled on. Combust isn't affiliated with or endorsed by any car maker.
Sport holds gears and revs higher. Comfort shifts early like a daily driver. Paddles gives you − / + buttons to shift yourself.
How hard you have to accelerate before the engine goes flat out. Teslas pull hard, so the middle is a good start.
Location only works over HTTPS. In a Tesla, open the page in the car's browser and allow location when asked.
RPM, gear and load are simulated from speed. Combust never reads vehicle data. Keep the volume where you can still hear sirens, horns and your car's alerts.
