I really don't believe that 1950's designed 4 banger was "that" efficient.

The hand of God was on that design!

Very thermally efficient - very good at converting the heat into power,

modern engines are much much more efficient at producing more power - but a lot of the techniques to get more power actually reduce the thermal efficiency
