Aircraft Engines from 60-140 hp

Since the days of first tests with automotive air-cooled 4 cylinder horizontally opposed engines in the year 1978 in the course odf many years of development highly sophistacted and modern all-aluminum aircraft engines evolved where every component was adapted to the special requirements of aeronatiical use.

For example the very light Aluminum NicaSil coated cylinders, our very own crankshaft with altered crank and stroke, our very own camshafts, forged aluminium pisons -just to name a few- were introduced.

All of these developments were made in pursuit of one the common goal to have ample power available at a meer 3000rpm and at the same time with a  significant reduction in weight and reliability at hi-power settings.

Thereby today every Sauer Aircraft Engine features a TBO of at least 1600h!

Through an outstanding quality, a very low system weight combined with very high power @ low rpm’s and the reliability our engines are known for, Sauer Aircraft Engines feature advantages wich are only indirectly -if at all- apparent through a simple horsepower comparison.

We build aircraft engines that are engineered to impress
their pilots anew every flight!
