Has anyone heard this little tidbit about the construction of the new line of F-series trucks by Ford? I saw this on another message board:
Could make for some interesting truck fires next time out!

In the interests of lightening the overall curb weight of the new generation F-150 series vehicles, Ford has substituted die-cast magnesium as the material of choice for its core support assembly. As some will recall, the physical characteristics of magnesium are light weight coupled with exceptional rigidity (for it's mass). Ford saved almost 20lb. with this substitution.
Pros - light weight, stiffness, fewer bolt on parts due to intricacy of die-casting Vs stamping
Cons - Relatively expensive, extremely flammable.
Magnesium fed fires are almost impossible to extinguish with conventional fire control measures. Any underhood fire involving a magnesium part will result in a temperature intensity that would suggest outside incendiary accelerants, but would not necessarily be the case.
