The season started with very good results for Renault (podium in both first Grand Prix) but it ended badly with the team trying hard to get some points.

Many pointed out that the peculiar exhaust system chosen by the team had ultimately created problems for the car.

The R31's exhaust tips instead of being at the rear of the car were at the front under the side vents. According to Boullier, however, this risk could be overcome.

What was not overcome was the absence of Kubica due to his serious injury. Asked by Autosport magazine about the key factor affecting the team's performance, Boullier responded: “Robert, certainly".

Robert's absence cost him very directly in terms of speed and because it was also a blow to the morale of the team and everyone. But we also had indirect losses, και αυτό δείχνει την αξία του Robert. Ήταν η πίστη που χάσαμε και η δέσμευση ότι μπορούμε να τα πάμε καλύτερα. Και φυσικά, δεν ξέρουμε πόσο μας κόστισαν οι μπροστινές εξατμίσεις αφού τα πράγματα μπορεί να ήταν διαφορετικά αν είχαμε και τη γνώμη του Robert».

O Robert Kubica πλέον θα χάσει σίγουρα την αρχή του πρωταθλήματος του 2012 and it looks hard to compete in Renault colours, which was named Lotus Renault, since the team has already announced Kimi Raikkonen and Romain Grosjean.

Despite his poor season 2011 Boullier believes this experience will make the team stronger in the future.

He stated himself: "This year has been very difficult for our people, για μένα και για όλους στην εταιρία επειδή περιείχε πολλές ιδιαίτερες και πιεστικές καταστάσεις, ωστόσο μπορεί μέσα από αυτό να συνειδητοποιήσουμε τον τρόπο με τον οποίο μπορούμε να γίνουμε καλύτεροι».
