Force India has decided to stick with the same drivers as in 2014 and they are a good pair in my opinion.
Hülkenberg has always been a good driver and in my opinion he is one of the best drivers in Formula One. Perez on the other hand is a driver who is a bit off sometimes but is capable of scoring some very good points for him and his team. Perez was good at Sauber but at McLaren he couldn't beat his world champion teammate Jenson Button. Last year he got a podium but lost to Hülkenberg in points.
The comparing starts here and I will begin with Sergio Perez. First the year, then the former teammate and how the season went.
2011 - Kamui Kobayashi. Perez started his career with a very good and hungry teammate. Kobayashi was said to be a rising star but for some reason he isn't driving in F1 anymore.
The first season in F1 wasn't that good for Perez. Kobayashi got double the amount of points than Perez. Sauber was also a very weak team that year which didn't really give him a chance to show any skills.
2012 - Kamui Kobayashi. This time the Sauber was working much better than the year before and even Perez was driving better. He won Kobayashi with 6 points (66-60) and even got three podium finishes. The 2012 Malaysian GP was the best race ever for Perez. He almost won the race but got second place in the end fighting with the two time world champion Fernando Alonso. People were talking that Perez was going to replace Massa at Ferrari. In the end Perez got a contract with McLaren after Lewis Hamilton wanted to leave.
2013 - Jenson Button. Now it was time for Perez to show his real potential but he failed. Jenson Button was not an easy man to beat. Perez lost 73-49 in points and lost also his seat at McLaren to the newbie Kevin Magnussen. Not a good year for McLaren and not for Perez either.
2014 - Nico Hülkenberg. I will talk about him when I have compared his teammates first.
Let's take a look at the German superstar Nico Hülkenberg. Some say that if Kimi Räikkönen would have stayed with Lotus Hülkenberg would have joined Ferrari for sure.
2010 - Rubens Barrichello. The only season that Hülkenberg has lost to his teammate. As a rookie he got only half of the points that Barrichello got. But then on the other hand Hülkenberg retired twice more than Barrichello. The young rookie from Germany also shocked everybody by taking pole position in Brazil with a car that wasn't good enough for that.
2011 - This year he lost his seat when Williams needed a pay driver and signed Pastor Maldonado. Hülkenberg would have gotten a seat for sure in another team but Williams notified him so late that all of the seats were already taken.
2012 - Paul di Resta. Hülkenberg was back again and showed his teammate who's boss with the points 63-46. Hülkenberg was now a driver that every team was keeping an eye on. McLaren could have signed him for 2013 but thought that his 2014 teammate (Sergio Perez) was a better choice. An interesting question was in the air: If they would have signed Hülkenberg instead of Perez would they have signed Magnussen for 2014? We will never know and only wonder.
2013 - Esteban Gutierrez. This was a pretty obvious victory for Hülkenberg because he got over 8 times more points than his teammate. The points were 51-6! What a difference! Sauber were happy enough to keep him for one more season though. Hülkenberg was good enough to say that he wasn't happy with the car and returned to Force India who were glad to take him back.
2014 - Sergio Perez. He got Force India's first podium since 2009 but Hülkenberg won him in points and being more consistent.
If I would take a guess I would say that Perez will lose this time too because "the Hulk" is a very tough teammate to beat.
