A major investigation is underway after two people were killed when a luxury car crashed and erupted into flames during a police pursuit in NSW.

A critical incident has been declared following the horror incident at Strathfield in the early hours of this morning.

According to police, officers were patrolling Centenary Drive when they attempted to stop the driver of a silver Audi.

The vehicle failed to stop, with police launching a short pursuit which came to a shocking end when the Audi lost control, rolled and erupted into a fireball on the westbound on-ramp to the M4 Motorway at Homebush.

Fellow motorists and police attempted to drag the driver and passenger from the engulfed vehicle but were unsuccessful.

After fire crews were finally able to extinguish the flames, two bodies were found inside.

They are yet to be formally identified.
