Bruno Senna returns to his race-seat for the German GP while Karun Chandhok will step aside for test driver Sakon Yamamoto... 

Sakon Yamamoto: "I have a lot of good memories of the circuit in Hockenheim. I like the track layout with the passing point at the end of the long straight and also the Stadium sector, which is very challenging. There is always a nice atmosphere with the spectators at the grandstands and I am always looking forward to come back to Hockenheim. Compared to Silverstone, I think we are more competitive and we can achieve a good result again. The last race weekend was very exciting for me. Now, the team has given me another chance to race on Sunday and I will do my best to prove that it was the right decision."

Bruno Senna: "I am looking forward to the race in Hockenheim as I have had a podium finish in GP2 in 2008 and I really like this track. It is a very interesting circuit with a mix of a wide and fast new section and a twisty and technical old part, which makes it challenging to set the car up. The stadium area is extremely difficult to get right and catches the driver on how much speed you can carry and how much of the track you can use. Hockenheim is one of the circuits where downforce is not as important as Silverstone or Barcelona, so I believe we will be slightly more competitive against the other new teams and I hope to have a good battle against them."

Colin Kolles: "After the solid result we could achieve in Silverstone, we want to go on like this and show a good performance again. The circuit in Hockenheim has a mix of slow and medium speed corners, and it requires strong measures of downforce. Because of this mix, it will be challenging to find the right set-up for the car. About 60% of the track is run under full throttle and it is especially demanding for the aerodynamic efficiency of the car, as well as the engine."
