Follow live coverage of the Mexican Grand Prix weekend from the Autodromo Hermanos Rodriguez with F1i.
Formula One returns to Mexico for the first time since 1992, with the refurbished circuit in Mexico City having previously hosted a round of the world championship from 1963-70 and 1986-92.
The teams have been greeted with a damp circuit for the opening practice session following rain this morning, but conditions are due to improve throughout the day. Friday's running is forecast to be the best in terms of the weather, with rain predicted for Saturday and also a threat to race day.
Lewis Hamilton arrives in Mexico as the newly-crowned 2015 world champion, but there remains a close battle for second place between Sebastian Vettel and fellow German Nico Rosberg.
The teams will face a unique challenge at the Autodromo Hermanos Rodriguez, with the circuit situated 2219 metres above sea level, with the altitude impacting on downforce. While the cars will run maximum downforce, the difference in air pressure means they are predicted to perform as if using Monza-specification low downforce levels.
You can follow all the live coverage on F1i's live page, which can be bookmarked as it will provide commentary on every session of the 2015 F1 season.
