The exact cause of this horrible crash will be discovered at some point.
The tragic death of actor, racer, gearhead and all-around cool guy Paul Walker is still a shock to many. While his family, friends and fans continue to grieve, investigators are still trying to get to the bottom of what exactly caused the crash of the Porsche Carrera GT. Walker was a passenger, while his friend and business partner, Roger Rodas, was behind the wheel. Both men were experienced drivers, so it's possible mechanical failure of some type was the cause.
Because the Carrera GT is such a unique and complex machine, Porsche has reportedly sent in a team of its own experts from Germany to aid in the investigation. Law enforcement officials want a full analysis of the car, specifically information on its brakes, engine and body. The black boxes from the car have also been recovered, which should provide details regarding the Carrera GT's last recorded speed, whether the airbags deployed, and throttle info. Investigators are also interested in the tires, and fortunately one was recovered fairly intact because it wasn't completely destroyed by the fire. Porsche is covering all of the costs of the investigation.
