Jaime Alguersuari has apologised to the Toro Rosso team for the incident on the opening lap at Hockenheim that put team-mate Sebastien Buemi out of the race.
The pair collided under braking for the hairpin which resulted in Buemi losing the rear wing of his car.
Although he was able to make it back to the pits, the damage was too great to be repaired and the Swiss driver was forced to retire.
“I made a really good start and was able to pass three or four cars,” he said. “Then when we came to the hairpin, I was braking in the middle of the corner and my team-mate came from a long way back and ended up driving onto the top of my car. The damage was too bad for me to continue, which is a real shame after I had got such a quick start.”
Alguersuari himself was forced to pit for a replacement nose and dropped to the rear of the field as a result, eventually taking the chequered flag in 15th place.
“Regarding the incident with Sebastien, I was on the inside going into turn six and I braked well leaving enough space, but there seemed to be some problems in front of me, as the cars ahead all slowed much more than is normal,” he said. “I braked again, but it was not enough and I drove into him. Naturally, I am sorry for that. I had to pit for a new nose and we switched to the soft tyres at that point, having started on the hards.
“In terms of performance, the car was quite fast and I was able to do some good lap times. I am looking forward to doing better in Hungary, a circuit where at least I have already driven a Formula 1 car last year.”
