slipstream 

The area behind a vehicle moving through something where there is not so much air resistance (if moving through air. This can be used to gain speed before overtaking someone in a race.
Also if in space when your spaceship is in the slipstream of another it can't be detected by the other ship's sensors (but this is only if you are in an episode of star trek).

Ooh ooh he's going to overtake him, he's gaining speed in the slipstream.
YES! he's done it and the crowd goes wild.

slipstream 

In auto racing, it is the zone right behind of a moving car. This zone has reduced air resistance and thus, allowing higher speeds...

Driver B got directly behind Driver A's slipstream, and was able to pass him easily..
