Spied: 2016 Ford F-Series Super Duty Prototype Goes Down in Flames - MotorTrend Magazine

The fire, which started at the driver's front wheel well, completely consumed the truck's front end in just three minutes. After 21 minutes, the prototype was completely destroyed, leaving behind charred remnants of the frame and piles of molten aluminum. This confirms that most of the Super Duty is made of aluminum , answering the question of whether the larger truck would get the same lightweight engineering as the F-150. The 2015 F-150 is about 700 pounds lighter than its predecessor, so don't... The melting point of Lead is 622 degrees F. Aluminum is 1221 degrees F. Steel is 2500 degrees F. I have had two cars catch fire, an old Jeep CJ-7 where the water hose burst and a Toyota Celica where the rusted hood hinge fell onto the battery post. Lightweight steel is much safer and sensible way to achieve better gas mileage in car construction than using melty aluminum held onto a steel frame with glue. Just at a guess it was probably a fuel leak since Fords have fuel tank / plumbing on the left side.
