Everything seems to be looking good for the team in terms of on-track performance at the moment?
Eric Boullier: We've certainly been delivering well on track at the last few races, so there's some good positivity coming out of Enstone looking to the remaining four races of the year. We did see a little dip in performance at the final two European races of the year leaving us with some ground to make up in both Championships, but certainly we look to be well placed relative to our opposition.

How satisfying was it to see an Enstone car leading for half of the Japanese Grand Prix?
EB: It was particularly satisfying. As Team Principal you are aware of all the work that goes on behind the scenes to try to make your car faster than the opposition. It's a relentless battle, so for everyone at Enstone it was a great sight to see one of our cars leading for so much of that race. For Romain himself it was a fantastic performance. It's no secret that he hasn't always had the easiest time of it as a Formula 1 driver, but it's clear to see how much his approach has matured this year and the results of this can be seen in how he is delivering on track. It's great to have both drivers delivering so well with a car which is one of the best on the grid.

Is the team any closer to making an announcement regarding 2014 driver line-up?
EB: There are no announcements yet but there is plenty going on behind the scenes. We know that Kimi is headed elsewhere for next season, but we also know that Romain would bring good continuity as well as the strong performance potential we've seen recently. There are a number of other good drivers on the market at the moment, so we're in a strong position of being able to assess the possibilities. A race seat with Lotus F1 Team is pretty hot property at the moment, so we're confident we'll have a strong line-up in 2014.

There's been a lot of talk regarding the team's finances recently...
EB: There has been a lot of talk, and there are a lot of positive things happening behind the scenes. We'll certainly be shouting from the rooftops when everything is finalised as we should be exceptionally well placed looking to the future.

How strong is the team's technical strength looking to 2014?
EB: It's true we've had a few people leave in 2013, but we've also been recruiting ourselves. There's been quite a lot of movement recently; not just within Enstone, but between other teams too. It's part of the sport and always has been. The strength of our technical department can be seen by the successful introduction of the long wheelbase E21. This change was driven by a new approach to how we develop the car and it's been a valuable proof of concept as we look to develop next year's model. I'm confident we can continue our recent run of form and improvement next year.

What's the aim for the remaining races this season?
EB: Podiums, podiums and podiums; we need points to help us with our Championship fight and you score the most points when you're spraying the champagne! Of course, we want to be winning races and we'll give our all whenever there is a sniff of victory, just like in Japan. There's one fundamental problem with trying to win at the moment, and that's the pace of the Red Bulls. We'll keep pushing and if we can beat them again this year it would be a tremendous performance.

What is possible in the Constructors' Championship?
EB: If we continue as we have done for the last few races, then mathematically second in the standings becomes a very attainable target. Of course, we all know that anything can happen in this sport, but second place would be an amazing result so we'll push as hard as we can and you never know what might happen.

What's the feeling after the Japanese Grand Prix?
Alan Permane: There was a lot to be positive about after our performance at Suzuka. Romain had a fantastic day - leading for 26 laps and genuinely looking like he was in contention for the win for a portion of the race - whilst Kimi was able to demonstrate similar pace in clear air as he worked his way up the order superbly at a track where overtaking is a challenge. After strong performances in both Japan and Korea before it, we head to the next two races with good confidence.

What do you think of the Buddh International Circuit?
AP: It's a good track with a mixture of challenges, but nothing particularly tricky. There's a steep uphill section into Turn 3 followed by a sizeable straight, a long banked right-hand corner and some quick changes of direction through Turns 5-9 and 13-14. It's a circuit where we expect the E21 to work well. Although we saw in Suzuka that we can compete on the harder tyres, our car generally favours the softer compounds making this a race where we're very much looking forward to continuing our run of strong recent performances.

Last year we struggled with a lack of grip and straight-line pace?
AP: DRS overtakes are tricky at Buddh. There was a double DRS zone last year, but even though there's a long straight it's not the easiest place to overtake. That said, we've seen some reasonably good attacking moves in the last few races and the softer allocation should help with passing opportunities too when differing degradation levels from different cars are factored in.

How much difference should the revised tyre allocation make?
AP: The change from hard and soft last year to medium and soft this year should make for quite a different race, where we saw one-stop strategies driven by the hard tyre allocation. Last year the performance gap between the tyres meant that everyone qualified on the soft and raced on the hard after a single stop. This year, the soft and medium compound open up the strategic permutations. With this season's tyres also being a step softer than last year's soft tyre, we have softer tyres to both qualify and race with. It could be a far more interesting race with strategy split between two and three stops.

How much are we still learning how to get the maximum performance out of the tyres; especially with the mid-season change to the construction?
AP: Even without any change we'd still be discovering how to extract the best performance, as you never stop learning in this area. We certainly learnt more about the tyres in Suzuka where we made changes to the setup overnight between Friday and Saturday, and this is knowledge we take to India.

The relative performance order seems to have changed a little between the teams recently?
AP: From our perspective there's no doubt that the long wheelbase car has benefitted our performance. It's difficult to put a figure on it with the fundamental change it has been, but it's an endorsement of all the simulator and modelling work we did in this area. We're qualifying better, racing better and we've been on the podium for the last three races at a variety of tracks from Singapore to Suzuka. These are about as different as you can get - one being a street circuit with super soft tyres, the other a very quick, flowing circuit on hard tyres - but it's clear that the E21 is working well on all variety of layouts. Add this to our increasing knowledge of the tyres, a few aerodynamic tweaks and both drivers being at the top of their game, and we're looking good.

Pit stops seem to be another area where the team has upped its game recently?
AP: It's an on-going battle to make the pit stops as quick as possible, but also reliably so. This is something which every team spends a lot of time looking at and we've made progress in two areas; new equipment and a performance increase from the crew themselves. We have a relentless practice programme where we constantly evaluate procedures and the speed of the stops. The crew have been working hard at this so it's good to see it paying off.
