A man is in custody after being arrested on suspicion of causing death by dangerous driving following a collision in Northolt.
An investigation has been launched and officers are appealing for witnesses and information.
At around 04:40hrs a BMW came to the notice of a patrolling police car due to the alleged speed at which it was traveling.
A short time later the BMW was involved in a collision with another vehicle, a Ford Focus, being driven by a member of the public in Ruislip Road.
London Ambulance Service and London Fire Brigade were called and attended.
Sadly the driver of the Ford Focus, a man aged 47, died at the scene. His next of kin have been informed and are being supported.
Two men in the BMW, a driver and a passenger, both aged 25, were arrested on suspicion of causing death by dangerous driving. They were taken to hospital, and their conditions are not life-threatening. The passenger has since been released with no further action.
The investigation is being led by detectives from the Serious Collision Investigation Unit who are working to establish what happened.
They would like to hear from anyone in the area who might have caught dash cam footage of the incident, or in the time leading up to it.
