How can a large creature be deceptively fast?

So as I was creating a variety of creatures I wondered if speed is exclusive to smaller creatures or if a large organism could move deceptively fast to take prey or predator by surprise. This is assuming the creature has the mass of an elephant (about 2 to 6 tons) but its body plan can be anything as long as it accommodates for the need for speed. The reason for this adaptation is probably due to predation and that the creature hasn't developed other survival mechanisms. I have not yet settled on wether I want a prey or predator but for the time being we can leave that aside, It's not like lions and antelopes run all the time.

How can a creature move fast for its size? What would its body look like?

The answer does not have to be if this could evolve just if this is possible within our knowledge of physics and biology. Any comment to help improve this question is welcome.
