Porsche that killed Paul Walker may have malfunctioned

The red 2005, Porsche sports car in which killed Paul Walker, crashed as a result of mechanical failure, possibly a steering fluid leak, according to sources closely tied to the auto shop where the vehicle was stored and maintained.

Sources with ties to Always Evolving, the shop co-owned by Walker and the Porsche driver Roger Rodas, told TMZ they saw evidence of a fluid burst and subsequent fluid trail before the skid marks at the accident scene.

According to TMZ, the Always Evolving sources point to the fact there is a noticeable absence of skid marks until just before the point of impact. They say if Roger had lost control the skid marks would show swerving, but instead the marks were in a straight line. They feel this cements the theory the driver didn't have steering control.

The fire spreading so quickly in the front of the car is another mystery. Sources say flames would be expected in the rear where the engine is, but fire in the front reinforces their theory of a fluid leak of some sort.

According to CNN, Paul's daughter Meadow, who is only 15- years-old attended the charity event, heard the explosion but did not see the crash.

"They tried everything to get them out of the car, but couldn't save them," Today Show reported.

Walker and his co-stars were already in filming for Fast and Furious 7.

According to TMZ, $500,000 Carrera GT was not modified and was driven rarely so they believe any failure must be a factory defect. As one source put it ... "Roger was a world class driver" and while he might have been speeding (as cops have reported) ... the notion he just lost control is preposterous.

See the wrecked car in flames now.
