The undulating Interlagos Circuit in Brazil's largest city is a challenge for drivers and teams. It is run anticlockwise and consists of a twisty infield portion between turns six and 12, with three long straights between turns three and four, turns five and six, and off turn 14 down the frontstretch before the beginning of the Senna โSโ in turn one.
Maximum downforce would be preferred through the tight and twisting section, but in order to maximize the straights, cars need to be trimmed out with as little drag as possible. Some downforce is already lost before a wheel is even turned, as Sรฃo Paulo sits 800 meters (2,625 feet) above sea level.
For HaasF1 driver Romain Grosjean securing more points than the Toro Rosso duo is the main object on this special circuit this coming weekendโฆ.
You endured a difficult weekend in the last grand prix in Mexico City. What were you struggling with and was it specific to the Autรณdromo Hermanos Rodrรญguez or do you expect to face similar challenges in Brazil?
Well, we struggled in qualifying with both cars. We didn't really have any pace. In the race, the pace was better but, unfortunately, my car was badly damaged following the contact with Fernando Alonso. So, we really struggled during the race with the damage. I lost a lot of downforce from the floor. It was a difficult one. I'm hoping that Brazil will be a little less challenging. Hopefully, we'll get better performance, which was the case last year. Mexico is a very special one, with the altitude and the cooling, and so on. We didn't have much downforce on the car. Obviously in the race, when we could've made some ground, the damage didn't allow us to do so.
When you have a tough weekend, do you dwell on it or do you try to put it out of your mind as quickly as possible and focus on the next race?
I think having a family is really good in this aspect. I go back home and I play with the kids. They make you forget you've had a tough weekend. You can always learn from it, and you need to learn from a tough one, but it doesn't put you down as it would if you maybe didn't have a family. They just boost me again, and I just use the experience to move forward.
With only two races remaining, the midfield is as tight as ever, specifically among Haas F1 Team, Renault and Toro Rosso. How would you characterize this battle, and do you find yourself looking at the time sheets to see where you stack up to the drivers on those teams?
I think out of those teams, Renault is the faster one. They've got a really good car through to the end of the season. They've had a bit more of a difficult time in the races, which has allowed us to close the gap and keep them in sight. Toro Rosso is the one we can try to go for. They're not performing better than we are, and they've got less experience amongst their drivers, so that should help us. We're going to do everything we can to get those positions because it's very important for the team.
Whenever Formula One travels to Brazil, Ayrton Senna's legacy is prominent. Of all his races, is there one that stands out for you?
Brazil is always special because of Ayrton Senna. He was one of the biggest names in Formula One. Interlagos is a special place. There's so much history there. On raceday you've got so much support from the fans. I remember Ayrton winning there in 1991 when he couldn't hold the trophy in the air because he was so tired and had the pain in his arms from driving.
Interlagos was resurfaced prior to the 2014 race. How much has the track changed since then and what do you expect this year with another year of weathering to the track surface?
It was good because it was very bumpy. Unfortunately, some of the curbs were changed and the nature of the track changed a little bit, which is a bit of a shame. Generally, it's a track I really like. It'll be interesting to see how it's evolved with the heavy rain we know you can get in Brazil. We'll just go out there and see what we can do.
Interlagos appears to be a very physical track, and heat often plays a role in the performance of the car and the driver. Considering these variables, how do you attack the track?
It's a pretty tough track with not much opportunity for a rest. Even in the straight lines you can't rest as much as you would like. You're at altitude as well, at 800 meters (2,625 feet), so coming from Mexico that's nothing, but you're still not at sea level. The weather can be challenging. It can be very warm and humid. It's a pretty intense challenge but, at the end of the day, that's what we're looking for.
Last year's Brazilian Grand Prix was run in the wet, but in 2015 when the race was run in the dry, the top-three finishers used a three-stop strategy. What needs to happen to make a three-stop strategy work over a typical, two-stop strategy?
I think it's the tire degradation and the tire delta time between the different compounds. Let's say you've got a soft tire, which is much faster than the medium, but degrades quite quickly, then you're better with three stops. If you run the medium, and the pace that it brings compared to the soft is favorable, and the degradation is low, then you should go for two stops. That's how it's calculated.
What is your favorite part of the Autรณdromo Josรฉ Carlos Pace?
I like the Senna โS', and the first few corners are pretty amazing.
Describe a lap around the Autรณdromo Josรฉ Carlos Pace.
You go onto the pit straight and then big braking to go to the Senna โS'. Very tricky turn in on the left-hand side. You really want to be well placed for the right turn two, which sets you up for turn three and the second straight. Big braking to turn four, left-hand side, 90 degrees, a pretty good corner. Then you get to the middle part โ turn five is a high-speed corner going up the crest. It's tricky. Then it's turn six and the hairpin on the right-hand side. We can't use the curb as much as we used to. Turn seven is a left-hand side corner, no braking, just a lift off. It's a bit of a strange one. The second hairpin is then on the right-hand side, a second high-speed corner going down the hill, prior to the last turn. It's a left-hand corner where you really want to go early on the throttle because you're facing a wall to go up to the finish line.
