F1 cars race round corners at more than 190 miles per hour. Those insane speeds are made possible by downforce - the invisible power which keeps F1 cars on-track.

Emel Cankaya is an Aerodynamics Specialist at McLaren. She tells Katie and Christian what downforce is, how F1 cars create it and what the front wing, rear wing and floor of the car do. She also explains how and why F1 teams change their downforce set ups for each racetrack, and how she got her job in Formula 1.

F1 Explains listener Brigit in New York asked us to explain downforce. If you'd like your question answered, send it to [email protected]
