Cops nabbed a hit-run driver whose Porsche fatally struck a young woman in Queens, authorities said.

Irene Lee, 56, was headed west in the sports car on the Horace Harding Expressway in Elmhurst at about 6:30 p.m Thursday when she lost control, cops said.

The Porsche then jumped onto the sidewalk, striking a 21-year-old woman walking by and a 26-year-old woman on a bicycle, cops said.

The younger woman was rushed to Elmhurst Hospital, where she succumbed to her injuries.

The bicyclist was treated at the same hospital.

After striking the women, the Porsche collided with a Mini Cooper and a Toyota Camry, injuring the drivers.

Lee then got out and fled, but was later arrested, cops said.
