Why are some F1 cars faster than others? Why do some upgrades work and some don't? Why don't F1 teams all just copy the fastest car? 

F1TV presenter and Drive to Survive star Will Buxton, and former Aston Martin Head of Race Strategy Bernie Collins join Katie and Christian to answer those questions in more in a quickfire Formula Why special all about F1 cars.

You'll hear what upgrading an F1 car has in common with online clothes shopping, why copying a successful car is like trying to cook without a recipe, and why F1 drivers get weighed after every single race.
