An Aylesbury man is in hospital with serious injuries following the crash which closed the main road into Watermead on Sunday morning.
The 25 year old, who was driving the black BMW, is believed to have suffered life-changing, but not life-threatening, injuries and is being treated at Oxford’s John Radcliffe Hospital.
The passenger, a 27-year-old man also from Aylesbury, was taken to hospital with serious pelvic and facial injuries.
His injuries are not believed to be life-threatening at this time.
The car smashed into bridge railings on the estate’s spine road at about 5.30am.
Firefighters used hydraulic rescue equipment to release the men from the car.
The road was closed for four hours while Thames Valley Police investigated the incident.
With only one road in and out of the estate, police redirected motorists to an exit usually only for buses on Lark Vale – which comes out in Elmhurst – where bollards were programmed to stay down until the scene was cleared.
Sgt Simon Hills said: “We would like to thank the residents of Watermead for their exceptional patience as the only road in to and out of Watermead remained closed until the bus entrance could be opened to relieve traffic pressure.
“We are appealing for witnesses who may have seen the black BMW in the Aylesbury area in the lead-up to the collision or may have seen the collision happen.”
A resident who lives near the spine road said he heard an ‘almighty bang’ which woke him up.
The man, who did not wish to be named, said: “I can see up the main road from my bedroom window. I was lying in bed and was woken up all of a sudden at about 5am by an almighty bang. I thought it was someone downstairs it was so loud.”
Anyone with information about the incident should contact PC Paul Taylor by calling 101.
