A 32-year-old man is fighting for his life after he was violently dragged by his own Infiniti Q50 along a Bronx street when he attempted to thwart a brazen broad-daylight car theft Thursday, shocking video shows.

The unidentified victim left his running vehicle double-parked on Westchester Avenue in Pelham Bay around noon to pick up Chinese food when an SUV drove up beside it, according to law enforcement sources and footage.

As the car thief emerged from the backseat of the SUV and quickly hopped into the driver’s side of the Infiniti, the victim raced from the sidewalk and attempted to save his car.

The man grabbed hold of the driver’s side window and attempted to run along with the car as it sped off, dragging him across the street, the video shows.

Officers found the victim badly injured with trauma to his head and leg a block away on Wilkinson Avenue, the NYPD said.

He remains in critical condition at Jacobi Hospital while the perp remains on the loose, authorities said.

The Infiniti was later abandoned and recovered on the northbound Hutchinson River Parkway, according to cops.
