A Staten Island high school teacher squabbling with her hubby steered her rage to his Porsche, pounding the pricey sports car with a metal rod Tuesday, police said.

Stephanie Tuzzo, 50, a business teacher at New Dorp High School, used the rod to bash the white two-door car, striking it several times as it sat in the driveway of their Thayer Place home near Hylan Boulevard in Bay Terrace sometime before 2 a.m.

She also used the rod to smash a window of their house and an air conditioning unit, police said.

Her husband called 911 to report the domestic incident and cops arrested the woman, who appeared to be intoxicated at the time, police said.

Tuzzo was arrested and charged with criminal mischief, officials said.

It’s not clear what sparked the fight between the couple.

New Dorp High School’s website says Tuzzo is a business teacher at the school.
