Amy Rose Wilson died in an accident in Falkirk around 6.10pm on Saturday.
Her death is being treated as a homicide and the black Mercedes has been recovered.
Police previously said there was an “argument” between the occupants of Ms Wilson’s silver Vauxhall Vectra and the Mercedes on Foundry Street.
A 39-year-old man driving a black Volkswagen Tiguan involved in the crash suffered minor injuries.
According to investigations, the Mercedes left the scene of the accident and drove north on New Carron Road, where the accident occurred.
Ms Wilson was pronounced dead at the scene. The passenger, a 22-year-old man, was taken to Edinburgh’s Royal Infirmary and released after treatment.
The 22-year-old man was arrested on a charge and released pending further investigation.
Chief Inspector Susan Balfour, of the Scottish Police Main Investigation Team, said: “It is important that we locate the occupants of the black Mercedes so that we can establish the exact circumstances of the incident.”
“I specifically request information on the movements of this car between 4:30 p.m. and 6:30 p.m. on Saturday 29 July. We know it has been seen in the Glasgow, Cumbernauld and Falkirk areas.
