Red Bull fly out new upgrades just in time for the season-ending Brazilian GP
Champions not resting on their laurels ahead of Sunday's showdown

Despite the team boasting race-winning pace in four of the last six events and securing a third successive Constructors' Championship last week in Austin, a suite of upgrades have been delivered in a bid to shore up Sebastian Vettel's title tilt.
"There's plenty of work going on with both Red Bull cars after new parts arrived this morning on a flight from London Heathrow," reported Sky Sports F1's Ted Kravitz from the paddock in an online blog. "We believe that there is a new rear-wing and new bodywork as well."
But with the RB8's competiveness not in doubt, it may be more significant that Vettel's car will be armed this weekend with a new-spec alternator. The team have suffered three race retirements this season due to an alternator fault and Christian Horner voiced his anxiety about the issue on Wednesday night.
"For sure, the alternator is a concern," the Red Bull boss acknowledged.
"It is something [engine supplier] Renault need to get on top of this week. They have run different solutions on different cars and hopefully they have enough data now to make sure we have a reliable version. It is not ideal at the moment."
Vettel himself has voiced his confidence that supplier Magneti Marelli will fix the problem in time for Sunday's showdown - but admitted there could be no guarantees of reliability.
"We're aware of it, we're not proud of it, but I think in terms of confidence for this race it is as high as it can be," the championship leader told Sky Sports News' Rachel Brookes. "We don't expect any trouble, but you never know - the cars are built on the limit, we've had this problem a couple of times but we don't expect it to happen again."
