The hybrid trucks are a bit noisier than the cars, so the Chevy Silverado Hybrid shouldn't need to have noise emitting speakers installed under the hood. And with the hemi engine popularity at Dodge Reading, none of their line up should be too quiet! Beginning at the end of this month, consumers in Japan can spend $148 and have speakers installed under the hood of their car so that their eco-friendly Prius will make the same amount of noise as regular cars. The success and popularity of the system in Japan will likely determine whether or not the system is made available in the United States.
So why is the Prius too quiet? Well, because engineers have advanced the technology so much that the car is usually running on just the electric engine, people outside the car can't even hear that the vehicle is turned on, it is that quiet! Good luck to the hybrid engineers to make the car louder and still retain those precious miles per gallon!
