Police cars have sirens.
To warn other cars it is coming through!
Policies and laws vary from state to state, but in my locality, police officers basically use sirens (and lights) any time they are responding to an emergency call. If they are responding to a silent alarm, they may choose to not use sirens, but that's not common around here.
the sirens tell people that a car is coming also it sends a signal to stoplights for a go.
Chicago is famous for having only Blue lights on its police cars

They have upgraded engines. They have additional lighting.. beacon lights, wig-wag flashers for the head and tail lights, radios, sirens, a shield between the driver compartment and rear passenger area, a rack for the shotgun, etc.
Lights, and Siren.
The french police drive terrible cars with terrible sirens were as the Miami police department drive good cars with good sirens, also they have a better way of processing people and information in the Miami police department. Also, the Miami police probably need better training, because Miami is the most crime-filled state in the US.
Looking at pictures of these Police cars it does not look like they had sirensAdded: I believe that they used alarm bells or "military horns" (alternating high-low pitch)
