For the 2017 model year, Cirrus released the G6 SR20, which gets both an avionics upgrade and a new IO-390 Lycoming engine.
Cirrus said its decision to re-engine the entry-level SR20 is significant for a couple of reasons. For one, it plans to aggressively market the aircraft to fleet operators who’ve expressed a strong preference for a four-cylinder Lycoming over a six-cylinder Continental. Moreover, the IO-390 substantially reduces weight, while also stretching the TBO for high-use operations.
