Follow live coverage of the United States Grand Prix weekend from Austin with F1i.

Heavy rain is forecast throughout Friday and Saturday which could impact on running, but with so much wet weather predicted many teams will still be keen to get some laps in despite the conditions.

Mercedes has already wrapped up the constructors' championship and Lewis Hamilton goes in to the United States Grand Prix weekend with the opportunity to secure his third drivers' title. Hamilton needs to outscore Sebastian Vettel by nine points and Nico Rosberg by two in order to take the championship.

Hamilton's hopes have been helped by Ferrari bringing a power unit update which will see Vettel and team-mate Kimi Raikkonen both take 10-place grid penalties after qualifying.

Red Bull expects to be more competitive in Austin than it was in Sochi, with the high-speed corners of sector one suiting the RB11. Renault also has a power unit update available at Circuit of the Americas, but Toro Rosso has opted not to use it and Red Bull is expected to follow suit.

McLaren will be keen to get in some mileage to compare power unit specifications as Fernando Alonso runs a new Honda engine while Jenson Button remains on the previous version this weekend.

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.
