Sauber team principal Monisha Kaltenborn hit out at drivers Marcus Ericsson and Felipe Nasr following their on-track collision in Sunday’s Monaco Grand Prix.
Nasr was given the call to let Ericsson past when running in 15th place with 30 laps remaining, but demanded to be given a reason by his Sauber team.
Ericsson joked that his teammate’s radio must not be working before taking matters into his own hands and trying to force his way past on-track at La Rascasse.
The two drivers collided and spun before ultimately retiring within a few laps of each other.
The stewards looked dimly on the incident, handing Ericsson a three-place grid drop for the Canadian Grand Prix.
However, Kaltenborn felt that both of her drivers were to blame for the incident.
“It was unacceptable behaviour by both drivers,” Kaltenborn said.
“Today the work of the whole team ended in a collision. Marcus and Felipe both know how much work is put into every race weekend. They have the responsibility to make it to the end of the race.
“After evaluating the overall situation, it was important to bring the fastest car as far as possible to the front, so that we were able to used any chances. Our decision was based on the data from both cars.
“After this, we have clarified the situation internally and both drivers are aware of their responsibilities. Such an incident will not happen again.”
Both Nasr and Ericsson apologized to the team for the incident.
“I was told that Felipe received a call via the radio. Then I saw a gap and tried to overtake him, but we all saw what then happened,” Ericsson said.
“It is a difficult situation for us, and it is even more important to stick together as a team in these times.
“I apologize, and I am sure that this will not happen again in the future.”
Nasr added: “For me it was not the right timing to swap positions. Suddenly, in Rascasse I felt my car being hit. It is surely disappointing for everyone as the whole team works very hard.
“I apologize for what happened. We need to make sure that this will never happen again.”
