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]


Austro Engine E4 (AE 300)Edit

Reciprocating four-cylinder, four-stroke diesel aircraft engine, marketed as the AE 300, it produces 170 hp (127 kW).[1] Certified through the European Aviation Safety Agency EASA on January 28, 2009 and through the FAA on July 29, 2009. The E4 is installed on various types of Diamond Aircraft Industries aircraft.[2]

Austro Engine AE 330Edit

Derived from the AE300, the AE 330 produces an increased 180hp (132kW) of power.[3] Two AE330s are used to power the Diamond DA62.


Single rotor Wankel engine with 294 cm3 (18 cu in) displacement, 55 hp (41 kW) and a weight of 28 kg (62 lb).[4] The AE50R is installed on the Schleicher ASH 30, Schleicher ASH 31 and Schiebel Camcopter S-100.


Further development of the AE50R. No certification. Twin rotor, 588 cc (36 cu in), (max) 75 hp (56 kW) at 7000 rpm, 33 kg (73 lb).[5]


Another development of the AE50R with a power output of 80 hp (60 kW), announced in January 2013.[6]

The AE500 on display

Based on Steyr Motors' M1 3.2 liter "Monoblock", the AE500 (6-cylinder, 280 hp (209 kW)) is the result of the cooperation between the two companies. It was intended for use in the Diamond DA50[7] but was instead replaced with the Continental CD-300.[8]
