Walker, 40, was a passenger in the high-speed Porsche Carrera GT when it spun out of control and slammed sideways into a light pole and small tree.
The driver, friend and business partner Roger Rodas, was killed instantly by multiple trauma from the crash, the Los Angeles County Coroner’s Office report confirmed.
Walker and Rodas died “within seconds” of the crash, according to Los Angeles County Coroner’s Office Assistant Chief Ed Winter.
Both bodies, burned beyond recognition, were identified through dental records, and Rodas was confirmed as the driver of the car, according to the report.
Porsche USA, which oversees the brand in the United States, has repeatedly failed to return telephone calls for comment or a statement.
The crash, so far, has been ruled an accident, according to gossip site TMZ.
According to a newly released security camera video, the car may have smoldered for up to a minute before it burst into flames. That would have given Walker enough time to get out of the car. But in all likelihood he was unconscious as a result of his injuries.
It’s unknown at the moment whether he could have survived those injuries if he could have been pulled from the car before the fire began raging.
Earlier reports, citing witnesses, said the “Fast & Furious” movie star was still seated in the car and was wearing his seat belt as it burned.
The Carrera is equipped with driver’s and passenger’s front and side airbags, according to Porsche specs. It’s unknown at the moment whether they deployed.
Although the car was demolished, it’s carbon-fiber construction is reportedly designed to tear away in a crash to help absorb the force of the impact.
Toxicology results will be available in 6 to 8 weeks, according to the coroner’s office.
Rodas lost control of the exotic $440,000 sports car as he was coming out of a sweeping right hand turn on Hercules Street, which makes up part of a loop through an industrial park. The road is frequented by hotrodders who show off their drifting skills.
Rodas and Walker co-owned a car shop about 500 yards from the crash site. A car show, sponsored by Walker’s charity, was being held that day at the shop and the Carrera GT was one of the featured autos.
As the show was winding down, the two men decided to take the car, owned by Rodas, for a spin.
