BTW, I am not saying the tailgate ignited the fire.
But I wouldn’t use FCA’s decision making as a template for safety; their main objective is to save a buck —and weight— wherever they can.
In its natural form, magnesium is classified as highly flammable.
According to the Wiki:
“Magnesium is highly flammable, especially when powdered or shaved into thin strips, though it is difficult to ignite in mass or bulk. Flame temperatures of magnesium and magnesium alloys can reach 3,100 °C (5,610 °F),although flame height above the burning metal is usually less than 300 mm (12 in). Once ignited, such fires are difficult to extinguish, because combustion continues in nitrogen (forming magnesium nitride), carbon dioxide (forming magnesium oxide and carbon), and water (forming magnesium oxide and hydrogen, which also combusts due to heat in the presence of additional oxygen). This property was used in incendiary weapons during the firebombing of cities in World War II, where the only practical civil defense was to smother a burning flare under dry sand to exclude atmosphere from the combustion.”
JL's hood is aluminum, too.this is fishy. doors and the hood gone completely is a little weird. the top i don't worry about as it could be a soft top. doors are aluminum and would puddle up in and around the jeep. hood is cheap steel that would have also just buckled but been still existing. interesting. i doubt we will ever find out.
