Jun.6 (GMM/Inautonews.com) Sauber is “not happy” with its engine situation in Canada, according to team driver Felipe Nasr.

Team boss and co-owner Monisha Kaltenborn has had to deny speculation in Montreal that Sauber is not running Ferrari’s new engine upgrade this weekend for financial reasons.

Rather, she said it was a strategic move.

But Sauber rookie has indicated the Hinwil based team in fact had no choice.

“The team is not happy,” he is quoted by UOL Esporte.

“Monisha has said that everything we receive should be in the form of equality. It’s not my question to be talking about it,” Nasr added.

“The update should arrive for our team in Spa,” the 22-year-old Brazilian driver said.
