Jun.5 (GMM/Inautonews.com) Felipe Nasr has clarified his recent remarks about Sauber.

According to Brazil’s UOL Esporte, the rookie reportedly said recently that the Swiss team’s 2015 progress had stalled due to a lack of car development.

But in Canada, the Brazilian rookie clarified that he is not unhappy with the Hinwil based team.

“It’s something we knew about from the beginning,” said Nasr. “I was not complaining, I’m just saying the situation so that people understand that our car has not changed.”

Nasr revealed that Sauber is in fact planning an upgrade for the Belgian grand prix after the summer break.

And it is there that the team is also expecting to receive the newly-improved Ferrari engine, even though the works team is using it in Canada.

Nasr said in Montreal: “We are not getting it here. Probably we will get it at Spa.”
