It has given us more action, more overtaking and more chances to change the race with strategy. DRS, the Drag Reduction System, can help F1 drivers get in position for a race-winning overtake. Why was it introduced? How does it work? What's the best way to use it?

F1 Explains with the help of three experts, who tell Christian Hewgill and Katie Osborne all about this fascinating subject:

• McLaren Aerodynamics Specialist Emel Cankaya works on designing DRS systems. She explains the physics of DRS, why it makes cars go faster and the rules on DRS design

• Alfa Romeo's Head of Race Strategy Ruth Buscombe studied DRS at university. She tells us how DRS is controlled and how it has changed F1 racing for strategists

• Former Renault F1 racer Jolyon Palmer puts us in the cockpit to explain DRS driving and overtaking
