the ability of a quadruped to use all of its legs for acceleration and braking. Elephants are said to possess this ability. This is possible because power is imparted to each leg. Other quadrupeds are said to have rear-leg drive. Such animals use forelegs for braking and hind legs for acceleration.
Elephants are the only four-footed animals that are blessed with four-leg drive.
