Can Red Bull challenge in this race? Daniel Ricciardo was 0.5 seconds off in qualifying, but that is a smaller gap than might normally be expected and on race pace on Friday Red Bull - and particularly Ricciardo - were right there.
The intrigue is that while Max Verstappen in fourth starts on the soft tyres like both Mercedes drivers, Ricciardo is on the super-softs. That’s a strategic disadvantage in theory as the super-soft is not as good a race tyre as the soft. But quite often in such situations the difference actually turns out to be minimal in the race and the super-soft will give him extra grip off the line, on the grippy side of the grid. If he can get amongst the Mercedes on the first lap, it could be game on for Red Bull with split strategies to keep Mercedes guessing.

There's been a whole host of celebrities knocking about in the paddock over the course of the weekend and chef Gordon Ramsey has popped along today.
Nice trainers.
Red Bull's Daniel Ricciardo, third on the grid, tells Sky Sports: "I'm looking at a better start than Lewis and Nico and hopefully get the lead on lap one.
"It will not be a breeze but if we can get a good start on the super softs we can get at least one of them."
Having beaten Nico Rosberg to pole position, clocking the fastest lap ever at the Circuit of the Americas in the process, you'd be forgiven for thinking it's been a pretty perfect weekend for Lewis Hamilton so far, and it has, but I'm bettering there will be a little niggle in the back of the Briton's mind.
Mercedes broke curfew on Friday night to change Hamilton's fuel system and while the team have insisted it is only minor issue that won't affect Hamilton in the race, he doesn't seem quite so sure.
"Maybe you should ask Toto [Wolff] about it," Hamilton said on Saturday. "He knows more, and there are knock-on effects, actually."
Here are some of the stories you may have missed from today's newspapers.
The Sun on Sunday:, external Lewis Hamilton has been undergoing special sleep treatments – designed with help from NASA – to help keep him at full-throttle.
The Mail on Sunday:, external If Lewis Hamilton is trying to be the new James Hunt, he is failing miserably, says the son of the F1 legend.
Sunday Telegraph:, external Jolyon Palmer has hit out at Renault for failing to give him enough credit in his rookie season as the Englishman’s Formula One career hangs by a thread.

Do you agree with F1 bosses' decision to outlaw moving under braking? Or do you think drivers should be allowed to just get on with racing?
We've got a vote running asking that very question so feel free to join in and also let us know what you think via #bbcf1, text in on 81111 (UK only) or post a comment on the BBC Sport Facebook page.
There was a pretty significant development off the track yesterday as the FIA issued a clampdown on "potentially dangerous" defensive moves.
Some F1 drivers have been unhappy with the way Max Verstappen sometimes moves under braking and it was the subject of a heated discussion in Friday's drivers' briefing.
Asked how he felt about sitting in a meeting where other drivers were complaining about him, Verstappen said: "It's funny. I just listen to it. In the end, everyone can have their own opinion.
"I did say some things, but it doesn't really make a lot of difference does it? I speak for myself, for what I think is right. That's what I did."
Verstappen also said he had no plans to change his driving style, despite the clarification.
This is like a home away from home for Lewis Hamilton. He's won three of the four US GPs in Austin while Nico Rosberg is yet to taste victory on the circuit.
History is certainly on the Briton's side, but he knows he'll have to nail his start and hope for no engine trouble to have a real chance of maintaining his impressive record at the circuit.

There's still plenty of Taylor Swift fans at the circuit today for the race itself. Excellent attire.
Love how American the truck is for the drivers' parade.
The attendance for the US GP has dwindled in recent years but some clever work by the race organisers has seen them boosted this weekend.
A Taylor Swift concert - her first of the year - has been incorporated into the weekend, and 100,000 watched her perform last at the circuit night.
If Lewis Hamilton is to win a fourth world championship then the task is simple - win the four remaining races of the season. Easier said than done for someone who hasn't won a race since July's German Grand Prix.
But even if he manages that it might not be enough because if Nico Rosberg comes home second in each of the remaining races, then he will be world champion.
The pressure's on but the good thing for us observers is, it should make for a thrilling finish to the season.

Objective number one for Lewis Hamilton at the United States Grand Prix has been achieved - get pole position. Now for objective number two - win the race. He has the speed; that’s abundantly clear from his pole position and impressive form leading up to it. But first he has to get off the line cleanly, and then he has to have a trouble-free race, two things that have proved difficult in recent grands prix.
“I feel great,”Hamilton said on Saturday evening. “I practised last week (at the factory). I worked hard on the process sequence we have and the starts I’ve had this weekend and I plan to carry that through to tomorrow.”
With a 33-point deficit to begin to close and only four races to do it, Hamilton has to have a good afternoon or the championship is as good as gone.
The United States Grand Prix, 2015.
With seven laps remaining, Lewis Hamilton moved into the lead and closed out the race to seal a thrilling victory and with it his third world championship. His fight with Nico Rosberg was over.
Today, with four races remaining and 33-point deficit to make up, that fight is very much still on but this time it is Rosberg who is warming up to land the knockout blow.
Nothing but victory today will do today for Hamilton. Having secured pole position in qualifying yesterday, he is well positioned to get it, just as long as his engine plays ball....
