High Quality Content by WIKIPEDIA articles! The Airbus A320neo family is a series of enhanced versions of the A320 family under development by Airbus. The letters "neo" stand for "New Engine Option". The main change is the use of larger and more efficient engines which is predicted to result in 15% less fuel consumption, 8% lower operating costs, less noise production and a reduction of nitrogen oxide (NOx) emissions by at least 10% compared to the A320 series according to Airbus. Customers will have a choice of either the CFM International LEAP-X or the Pratt & Whitney PW1000G. The airframe will also receive some modifications, including the addition of "Sharklet" wingtips to reduce drag and interior modifications for the passengers comfort such as larger luggage spaces and an improved air purification system.
