If you are wondering if a “Loud Pedal” refers to the musical percussion instrument called a “Piano,” think again! The loud pedal on a piano makes the piano go louder, and the loud pedal on a car makes it louder AND faster (the latter of the two the piano CANNOT brag about!).
With cars, when you press the “Loud Pedal,” more gas and air flow into the engine, making it spin faster and rev higher. This makes the car louder, hence the name “Loud Pedal…”

he’d better, otherwise I might hire a copyright lawyer!
