A BMW barreling down a Brooklyn road at 90 mph smashed head-on into a minivan and killed a Pakistani immigrant who dreamed of becoming a doctor, police said.



Jamal Iqbal, 23, was driving his Ford Winstar north on Ocean Parkway in Sheepshead Bay near Avenue X about 11:45 p.m. Saturday. At the same time, Beka Skhirtladze, 26, lost control of his 560-horsepower BMW M6, spun out and crossed over into Iqbal's lane, police and witnesses said.



Skhirtladze — going at triple the limit in the 30 mph zone — was hit with criminally negligent homicide, vehicular manslaughter, reckless endangerment and reckless driving charges for speeding and reckless driving, police said.



A witness who was sitting with his wife on a bench near the roadway said the BMW was moving at a dangerous speed.



"I said to my wife: 'This guy is going too fast,'" said Mohammed Sadiq, 63.



"The guy in the van probably didn't even know what happened, it was so fast," he added.



The devastating impact could be heard from several blocks away. A man who lives two blocks from the crash site told the Daily News it sounded like "an explosion."



The impact tore Iqbal's minivan apart, sending the engine and transmission across the road.



The BMW spun around several times and came to rest facing the wrong way in the northbound lanes — about 150 feet from where Iqbal sat in the driver's seat, mortally injured.



He was rushed by ambulance to Coney Island Hospital, where he died.



Skhirtladze and a 30-year-old woman who was his passenger were taken to area hospitals in stable condition, police said. His injuries included a broken jaw, sources said.



Throughout the day Sunday, grieving friends and relatives of Iqbal visited the Sheepshead Bay home he shared with his parents.



"It's not fair," one woman wailed as she approached the home, sobbing hysterically. "I can't believe he's really dead."



Iqbal's friends said he was determined to go to medical school after he finished college.



"He was a really smart guy," said Azeem Ullah, 23. "He was always there for everyone."



"Everyone is crying," the friend added.



"His mother is shocked. She keeps saying, 'My son! My son!' His father is ruined. He gave up. He doesn't want to live anymore."
