Velocity is itself an expression of energy, and energy does scale linearly. Why does it take quardically more energy for each extra unit velocity? Well, because the closer you get to the speed of light the harder it is to get closer still. Why that is simply requires a deeper appreciation of the system than I expect is possible to muster in a comment.
