Why do small turbine engines cost more than car engines? They have less moving parts so you'd think they would be cheaper? Take the Alison 250 which has 250HP and weighs about 120 pounds.. it costs 300k. Whereas a V8 is like 12k, makes 500hp, and weighs 500lbs.

Are the tolerances really that much tighter in a turbine engine, or is it just because of mass production? I know that comparable piston aviation engines are only like 20k so it must not be quality control that drives up cost?
Wouldn't turbines make the most efficient, simplest, and lightest engine for a car if it's coupled to an electric drive system?

Because if your ls1 blows up you come to a screeching halt or if you're lucky coast to a stop
If your turbine blows up you 9/11 a few houses

They're not produced at the scale car engines are.

Turbine engines are on a totally different level from any piston engine, even the small ones operate at extreme temperatures and speeds which means expensive materials. Also, most of their sales are probably military contract, so the price is probably inflated from that, too.

to make a reliable turbine you need fairly exotic materials and more complicated engineering and manufacturing, which cost money.
