At least four people are dead from three separate collisions on Big Apple streets Sunday – including a fiery crash that killed two 22-year-olds and left the vehicle they were in unrecognizable.

The carnage on the road concluded around 11:15 p.m. Sunday when a 22-year-old man smashed the Chevrolet Corvette he was driving into a guardrail on the Staten Island Expressway while traveling east, police said, noting the information was preliminary.

The young driver and his female passenger, also believed to be 22, were both killed at the scene, police said.

The Corvette was totaled and charred from an apparent fire following the impact, according to footage from the scene.

It was the second deadly crash on Staten Island Sunday after a motorcyclist collided with a turning pickup truck around 3:30 p.m., police said.

The motorcyclist, a 29-year-old man, fatally crashed into a Dodge Ram as the truck was attempting to make a left onto 10th Street from New Dorp Lane, according to cops.

The motorcycle, also traveling on New Dorp Lane and in the same direction, tried to pass the truck on the left side and collided with the rear driver’s side of the Dodge, authorities said.

He was pronounced dead at the scene after sustaining severe head trauma.

The 21-year-old driver stayed on the scene following the incident, police said.

Across the bridge in Brooklyn at around 8 p.m., an electric bike rider was traveling east on Eastern Parkway when he collided with a Jeep traveling west on Eastern Parkway trying to make a left on Schenectady Avenue in Crown Heights, police said.

The unidentified adult e-biker was taken to King County Hospital where he was pronounced dead.

The driver of the Jeep remained on scene, police said.

No charges have been filed in either collision.
