Colin Kolles will leave the HRT Formula 1 team after reaching an agreement to end their cooperation, the Spanish squad announced. The team said the move was "due to the new direction that the team has taken and the decision of the new management to move the team headquarters to Spain."
Previously the team was based Germany, using the factory owned by Kolles. He had been HRT's team principal for the past two seasons.
"HRT F1 Team would like to thank Dr. Colin Kolles for his work and dedication throughout these past two years and wish him the best in his future projects," said the team in a statement.
Kolles was drafted in at HRT before the start of its debut season in 2010 after the original plans with Adrian Campos failed.
