Follow live coverage of qualifying for the Mexican Grand Prix from Autodromo Hermanos Rodriguez with F1i.
The first F1 qualifying session for 23 years at the Mexico City circuit is set to be a tight affair, with the top three teams covered by 0.211s in FP3. Nico Rosberg and Lewis Hamilton were just 0.014s apart at the top of the times.
There will only be 19 drivers taking part in the session, with Jenson Button missing qualifying due to reliability issues at McLaren. Button was only able to complete four laps in FP3 before he was confined to the garage and ruled out of this afternoons session.
Kimi Raikkonen will also be looking to make up for lost time after he stopped in FP3 with flames visible under the engine cover. Ferrari has been facing a race against time to get the Finn's car ready in time for qualifying, but he is expected to make it out in Q1.
Teams will also be keeping an eye on the skies, with a threat of thunderstorms around the circuit this afternoon.
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 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.
