The victim had been walking alone along Bradiston Road at 9pm on June 14, 2022 when a car, believed to be a dark coloured Audi A3, stopped at the junction ahead of her.
Police said an unknown man pushed the woman from behind into the vehicle, then drove away with her inside before raping her.
After the assault, the woman was pushed back out of the vehicle not far from where she had been picked up.
Detectives have released an e-fit of the man they “urgently” need to trace.
Police described him as speaking with a Jamaican accent and he is believed to be in his late 30s, tall with short dreadlocks, and a significant facial scar.
Detective Constable, Leon Riley, from the policing team covering Westminster borough, said: “If you recognise the man in the image please contact us without delay.
“We have been carrying out extensive enquiries since the incident and we continue to support the victim who, as far as possible, has been trying to live her life as normal since it happened.
“It was a horrifying ordeal for her and we thank her for supporting the investigation to trace the man responsible for assaulting her, and now helping us build an e-fit of the suspect.
“Women should be able to walk alone without fear and we are dedicated to protecting women and girls from predatory offenders such as this.
