Mexican GP: Why are the teams struggling so much in Mexico
Tom Clarkson speaks to Red Bull's team principal, Christian Horner, about what technical challenges the teams are facing this weekend at the first Mexican Grand Prix in 23 years.
The Autodromo Hermanos Rodriguez, is situated at over 2,200 metres above sea level, which means the thinner air moves across the cars more easily, but does not cool the engines and brakes as well.
Horner and Clarkson discuss some of the "on-the-hoof" engineering techniques that have been used this weekend as well as the down force requirements and tyre decisions each team are having to make.
