The victim, who was from the Cork city area, is understood to have been a passenger in the vehicle.
The driver of the car, a male youth, as well as three passengers, an adult male, a male youth, and a female youth, were being treated at Cork University Hospital yesterday with injuries that have been described as non-life threatening.
A woman in her 30s, who is believed to have been on her way home from work, was driving the other vehicle and suffered serious injuries.
It’s understood the car the teenagers were travelling in had an interaction with gardai shortly before the fatal collision.
The incident has been referred to the Garda Ombudsman for a full investigation.
Gardai have called for any potential witnesses to come forward.
They said: "Gardai are appealing to anyone with information to come forward to them.
"Anyone who may have witnessed the incident or who may have video footage (including dash-cam) is asked to contact Gardaí.
"Gardai can be contacted at Mitchelstown Garda Station on 025 84833, the Garda Confidential Line on 1800 666 111, or any Garda Station."
A spokeswoman for GSOC said: "GSOC received a referral from An Garda Siochana on 1 July 2023, following a road traffic collision in the Mitchelstown area of Cork that took place in the early hours of the morning.
"The referral was made by a Garda superintendent under section 102(1) of the Garda Siochana Act, 2005.
"The matter is now under examination by GSOC further to section 91 of the Garda Siochana Act, 2005. No further comment will be made at this time." Section 102(1) of the Garda Siochana Act, 2005 provides for the referral to GSOC by An Garda Siochana of "any matter that appears…to indicate that the conduct of a member of the Garda Siochana may have resulted in the death of, or serious harm to, a person".
Section 91 of the Garda Siochana Act provides for the examination by GSOC of the circumstances of a referral or complaint with a view to recommending what further investigative measures may be required.
Cork councillor Frank O’Flynn called on Transport Infrastructure Ireland to put warning signs in place on the road.
Mr O’Flynn said: "My thoughts go out to the family of the male teenager who has died and I also wish those injured a speedy recovery.
"I am taking it up with Transport Infrastructure Ireland as they are responsible for the road and this is happening too often."
