In F1, every thousandth of a second is crucial. Drivers' performances are often separated by less than the blink of an eye, so how are F1 cars timed so accurately?

To find out, Christian and Katie speak to James Clarke, a highly-trained F1 timekeeper. James explains the technology on cars and at circuits which make the timing system work, how lap times and race positions are accurately recorded, and what happens if two drivers set identical times.

They’re essential pieces of safety kit, made from specialised materials. But F1 helmets do far more than just protect the driver. F1 Explains explores helmet design, testing and technology with Stephane Cohen, co-CEO of Bell Racing – the company which makes helmets for 13 current F1 drivers. 

Stephane tells Katie Osborne and Christian Hewgill how Bell make helmets that are strong and light, visors that don’t fog up and why a car update can require helmets to be modified. 

Plus, hear how F1 helmets differ from those worn by the stars of the NFL.
