The Porsche GT, which the late actor was a passenger in, was travelling at approximately 93 MPH when his good friend Roger Rodas lost control and crashed.
It has been four months since the tragic death of the 'Fast & Furious' film franchise star Paul Walker.
On Tuesday (March 25th) the Los Angeles County Sheriff concluded their investigation and their report states the fatal crash was caused by excessive speed and not a mechanical failure.
The 40 year-old actor was killed when visiting a charity event in Santa Clarita, California, this past November (2013), he and friend Roger Rodas, (38) entered a Porsche Carrera GT sports car to drive round the block.
The new report determines that when the car crashed, after the driver lost control, it was travelling at 93 MPH in a 45 MPH zone when it collided with a post and tree, which caused the car to burst into flames.
"Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions," Los Angeles County Sheriff Commander Mike Parker said in a statement.
The investigation also claimed the sports car's nine year-old tires played a part in the tragedy.
In January an autopsy report determined Walker died from "combined effects of traumatic and thermal injuries," meaning the late did not just die from impact injuries, he also burned to death.

The driver of the Porsche GT, Rodas, died from multiple impact injuries alone, been burnt was not stated as a cause of death.
Following Walker's tragic death, filming for 'Fast & Furious 7' was postponed, but this will now recommence at the end of March.
The good news is that the 'Hours' actor will still be featured in the movie's final scenes as the production team will complete these with the use of stunt doubles and CGI, Universal Pictures announced on Sunday (March 23rd).
