Real Engine Sound is a device for electric cars designed to play the sound of a gas engine when the car is moving, providing pedestrians with an audible warning of an electric car’s approach. Electric cars have many advantages, but their relative silence can make it harder for pedestrians to notice when they are nearby, creating a dangerous situation. Real Engine Sound emits a strong engine sound to warn pedestrians and other drivers, and offers drivers a range of pre-recorded engines to choose from, including famous car makes and models. With a built-in amplifier and speakers, Real Engine Sound can be quickly installed into any vehicle, and is easily connected directly to the car’s controls via the OBD system.
