Quote: "An object that is sprung requires dramatically less energy to move than an unsprung object."

Translation: "I don't know anything about physics."

How did this nonsense get posted to Wikipedia?

The "less energy" is only true for an uneven surface. A normal tire would have to fight against the up/down movement. The sprung tire would act somewhat like a cam and transfer the up/down movement into forward movement.
