Definition: When a car travels through the air it leaves a gap behind it. Another car driving in this gap doesn't have as much air resistance pushing on it's nose and can then travel faster or use less fuel to travel the same speed.
This effect can be noticed at speeds as low as 70mph but the effect increases with speed.
Pronunciation: draft • (noun)
Also Known As: slipstream
Examples:
My car was slower than a turtle but once I got in the draft I was able to keep up.
