“The Fratzonic Chambered Exhaust—the name refers to a Dodge logo— combines various chambers underneath the Charger’s body with some woofers and mid-range speakers, all driven by a dedicated 600 W amplifier. The system is also designed to transmit vibrations into the chassis through elastomeric bushings, mimicking an internal combustion engine and its motor mounts.”
It is ridiculous, but it’s also exactly what is happening with loud combustion engines. Any sound coming from it is just higher-entropy (i.e., unused) energy being produced and promptly lost instead of contributing to power.
Thanks for the mansplanation. I am well aware of those facts as a mechanical engineer.
