Round 18 of the 2014 Formula One World Championship takes place in Sao Paulo, Brazil, at the Autodromo Jose Carlos Pace which has been home to the Brazilian Grand Prix since 1990. It’s a track that presents many difficulties, including the need to find the right compromise between qualifying and race trim, as well as total unpredictability of the weather.

A chance of rain is currently forecast for Sunday’s race, and Saturday’s qualifying could see stormy conditions. The peak temperature for the weekend should be around 70 degrees F (21 degrees C). Humidity will be around 73 percent and wind speed low.

Pirelli has nominated its medium and soft tires for the race instead of the normally harder compounds used in Brazil. This is because the track was completely resurfaced recently, meaning it’s slipperier than usual.

There were no disruptions during today’s practice session, with Mercedes AMG’s Nico Rosberg setting the best times. Right behind him was his teammate Lewis Hamilton who goes into the race with a 24 point lead in the 2014 Drivers’ Championship. Despite this gap, the winner won’t be determined here as there are double points up for grabs at the final race in Abu Dhabi later this month.

In the Drivers' Championship, Hamilton currently sits on 316 points, with Rosberg in second with 292 points and Infiniti Red Bull Racing’s Daniel Ricciardo in third with 214 points. In the Constructors’ Championship, Mercedes AMG has already been declared the champion and currently sits on 608 points. Infiniti Red Bull Racing is second with 363 points while Williams is in third with 238 points.
