What is the fastest land animal among big cats?

The cheetah is the fastest land animal among big cats.

Its speed comes from a specialized body: long legs, a flexible spine, powerful hindlimb muscles, large nasal passages, and enlarged heart and lungs. It can accelerate from 0 to 97 km/h in under three seconds, although it can maintain top speed only briefly.

Cheetahs are pursuit predators rather than ambush hunters. They use speed to close the distance across open ground, then rely on quick changes of direction to catch prey such as gazelles and impalas. Their long tail helps with balance and steering during these high-speed turns.

A common mix-up is the often-repeated claim that cheetahs reach 114 km/h or more. The highest reliably recorded speed is about 104 km/h. Cheetahs are also built for sprinting, not endurance: a chase usually lasts less than a minute, after which the animal needs time to recover.
