Investigators look over the wreckage of the Porsche Carrera GT in which Paul Walker was killed.

Paul Walker’s fiery death in a high-performance Porsche Carrera GT appears to be solely related to speed and likely driver error, according to the latest reports on the investigation.

The car had no mechanical problems and investigators have also ruled out debris and small illuminating discs in the roadway as contributors as well.

If speed and driver error are ultimately blamed for the crash it could take Porsche off the hook legally, although the victims’ families could raise an issue over design flaws that make the car inherently unstable, and therefore, unsafe to drive.

Paul Walker Car Crash: Theories Mount as to How It Happened

Atlanta-based Porsche U.S.A, which handles all inquires in North America, referred all calls to the Chicago office of its powerhouse public relations agency Omnicom Group Inc, which has failed to return several calls for comment.

Walker and his friend and business partner Roger Rodas were killed Nov. 30 in in Santa Clarita, Calif, after the 610 hp supercar came out of a sweeping right hand curve and began accelerating. It jumped a curb, struck a light pole and crashed into a tree.

The car, known for its tricky handling because of its light weight-to-power ratio and lack of traction control, went into a slide. Rodas may have been unfamiliar with the car; he’d driven it very little since buying it in 2005, according to friends.

TheImproper conducted an Internet search and turned up more than a dozen Carrera GT cars that crashed under very similar circumstances. Drivers simply lost control of the car while driving it aggressively.

Earlier, TheImproper also reported that investigators had found no evidence of a massive fluid leak, either from the brakes or power steering, as some colleagues of the two men had claimed.

“We’re looking at speed and speed alone,” a law enforcement official with knowledge of the investigation told The Associated Press (AP). The official was not authorized to speak publicly about the ongoing investigation and spoke on condition of anonymity.

Even so conspiracy theories have already sprung up about the accident.

Investigators are likely to uncover more information when Porsche engineers arrive from Germany in mid-January to examine on-board data collectors that track such things as engine performance, engine problems, speed and other data.

The data should provide solid information on the car’s speed. Estimates at the time of the crash have ranged from 40- to 50-mph to as much as 100-mph. The car broke in half with significant force and burst into flames, although the carbon fiber body is designed to break up to absorb the impact of a crash.

About 1,400 of the $440,000 supercars were built by Porsche before it ended production in 2005, due to poor sales.
