That is because the trailing driver gets many opportunities to pass the leading car and can bide his time sitting on the tail for a long time.

Drafting also reduces fuel consumption throughout the race. Senior Lecturer in Mechanical Engineering at the University of North Carolina at Charlotte. The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the . A trailing car (perhaps pushed by a line of drafting cars) uses the lead car's wake to pull up with maximum momentum at the end of a straightaway, enters a turn high, and turns down across the lead car's wake.
