Adrianna Magdalena Dereszewicz, 36, of Cherry Drive, Ellesmere, was taken to the Royal Stoke University Hospital after the single-vehicle incident on the A539 between Overton and Erbistock on February 3. She died two days later.
At the opening of an inquest into the death of the administrative assistant John Gittins, coroner for North Wales East and Central, said the provisional cause of death was given as head injuries.
The inquest was adjourned while police continue their investigation into the collision, in which the Vauxhall Zafira hit a wall on a right-hand bend.
North Wales Police have appealed for witnesses to the collision and in particular are trying to trace the driver of a Ford Transit-style van which overtook the Vauxhall shortly before the crash.
Officers say they have reviewed CCTV footage which shows two vehicles driven by people who may have seen what happened.
A car, and what is believed to be a Ford Transit, passed the Zafira in the opposite direction moments before the collision.
Sergeant Meurig Jones of the Roads Policing Unit, said: “Sadly the quality of the CCTV footage isn’t great.
“However we can make out that a car, and a white Ford Transit pick-up type vehicle – or something similar – were captured travelling from the direction of Overton Bridge towards Overton.
“They passed the Vauxhall Zafira moments before the collision at around 7.30pm."
