Austro Engine is an Austrian manufacturer of aircraft engines based at Wiener Neustadt in Lower Austria.


The production site and headquarters was built in 2007 with an investment of EUR 13 Million. The company was founded by Diamond Aircraft Industries and partners. The products are reciprocating engines and Wankel engines. The Wankel aero-engines are developed from the MidWest AE series engines developed at Staverton by MidWest, a UK firm that was bought by Diamond.[citation needed]
