The CVT will adjust its ratio to allow the engine to run at the speed necessary to make the required amount of power in the most efficient way for the given circumstance. Punching the accelerator would result in the engine revving up to make more power by lowering (numerically raising) the drive ratio, just like a regular automatic transmission. As you accelerate the engine will stay at a fixed speed while the transmission gradually raises (numerically lowers) the drive ratio. The fuel efficiency advantage is gained over a regular transmission in that there doesn't need to be compromises made when the combination of vehicle speed and required engine power can't be ideally met with fixed ratios. This is also the reason that the number of gears in regular automatic transmissions has gone from 4 to 6 or more in the last decade.
