Teen killed in possible street racing smash

Excessive speed is being blamed for a fatal crash in Sydney's west that damaged three of the four cars involved to the extent that police say they are unrecognisable.

Amin Asfouroh, 18, was killed on Sunday night when a Mitsubishi Lancer and red Nissan Pulsar crossed over the Hume Highway at Greenacre and hit two oncoming vehicles.

The 21-year-old driver of the Mitsubishi was taken to Liverpool Hospital with serious head injuries. Four other people suffered minor injuries.

Amin's Uncle, Mohamed Tabbah, told 7News the teen's family is distraught and described his nephew as a good boy who cared for his family and studied hard.

"Just a big shock to us all, just the only son we had," Tabbah said.

"Just got to grieve, accept it and god's created us all and he'll take us when he wants so you gotta have strong faith."

Friends have also taken to social media to express their grief.

"May you rest in paradise inshalah (God willing)!," a friend is reported as saying.

"You where [sic] a friend and a brother too us all [and] always had a smile on your face we all love you," according to another friend.

Detective Inspector Phil Battin says speed was almost certainly a factor.

"Here we are again leading into the holiday period and speed of course appears to be the factor in this particular collision," he said.

"Three of the four vehicles were almost unrecognisable.

"The fact is speed limits exist for a reason."

Det Insp Battin could not confirm reports that drag racing might have been a factor in the crash.

Earlier on Monday, Detective Inspector Dave Firth told Macquarie Radio that drag racing had the potential to destroy families.

"Any vehicles involved in street racing are taking a very big risk both with their own lives and those of the other occupants of their vehicles," he said on Monday.

"You've also got to have a consideration for other people related to them, and the impact it has on them."
