A number of years ago a LLNL study put the manufacturing portion of
total life cycle energy consumption of an automobile at close to 50%.
Increased use of plastics, thinner/recycled steel, and greater lifespans
have reduced this somewhat, but it is still in the same order of
magnitude with roughly 1/3 of the total life cycle energy being used
just to build a car. Not what I would call minuscule, but headed in the
right direction.
Manufacturing has never been over 5%. Where did you get that data?
It's expected to go up, with increased use of lightweight materials, but
total life-cycle energy consumption will go down.
