The S4 is designed to be super quiet

The S4 fits one pilot and four passengers, cruises at 322km/h, and has a range of about 241km on a single charge.
It runs on batteries, uses six tilting propellers for smooth takeoff and landing, and is designed to be super quiet—quieter than city traffic.
After racking up 50,000-plus test miles already, safety features like triple-redundant controls are built right in.
