Aircraft engines are both efficient and reliable. Believe it or not, aircraft engines designed in the late 1930's have a BSFC (fuel consumption per hour per HP) that matches the best engines today. Those engineers were brilliant and truly did understand what they were doing.
Today's turbine engines produce far more power, and are exceedingly reliable. But they are not more efficient.
Radial engine porn.
