So if your increasing your speed from 10mph to 20mph, it'll still require 4 times the power...except at those speeds, you might only be using 3hp to maintain 10mph (or 12hp for 20mph.)
But if you're doing 50mph, and you want to do 100mph, where it might be 50hp to do 50, you'll need 200hp to do 100mph...and exponential jump!
Someone correct me if I'm wrong....

Doubling your speed requires
8 times the power.
Drag force is 4X as much at double the speed.
Power is a function of force * velocity.
