Re: A new Saab?
A turbine cost less to manufacture in large quantities than the average 4cylinder aluminum engine. The reason turbines are thought to be so expensive is because most people see turbine engines from Boeing that are pushing over 20,000hp or steam turbines that where pushing between 180,000 - 650,000hp (when I retired).
Also the average 450hp turbine only needs servicing about every 100,000 hours and has a lifetime of somewhere around 45,000,000 hours of life.
A good estimate on the cost of a 450 turbine with a proper gear box would be about $3,500usd.
