Probably three reasons....Cost, cost and cost.  It's cheaper to design
it so it doesn't need it.

No realy, cost is a factor but also reliability, production engines for
the masses must be designed to work for a long time, without proper
care, under extreme conditions, so they are over engineered to a point.


If a production engine was designed to the point where it really needed
thermal coatings it would probably not meet the above criteria.

You see them in applications where the demand is the greatest and in
some conditions actually a requirement for any kind of longevity.

Sounds like a great idea.  It bothers me that I've only heard about
thermo-barrier coatings on race car engines, exhaust systems and gas
turbines, and not any production auto engines. Makes me wonder why the
automakers aren't using them.  Seems like a relatively inexpensive
improvement.
