New Option: Aircraft for sale A320CEO /& NEO (2020). Airbus developed a new version of the A320, called A320neo, for new engine option, based on more efficient engines, at least partly in response to the threat posed by Bombardier Aerospace's development of the CSeries airliner, with which Bombardier hoped to compete directly with Boeing and Airbus for the first time. The choice for new engines include the CFM International LEAP-1A and the Pratt & Whitney PW1100G. Though the new engines will burn 16% less fuel, the actual fuel gain on an A320 installation will be slightly less.
