How does the A320neo compare to the previous A320 model in terms of fuel consumption?

The A320neo, which stands for "new engine option," is specifically designed to be more fuel-efficient compared to its predecessor, the A320. One of the major advancements in the A320neo is the incorporation of new, more efficient engines, such as the Pratt & Whitney PurePower PW1100G or the CFM International LEAP-1A. These engines utilize advanced technology that enhances their performance while reducing fuel consumption.

The claim of up to 15% fuel savings denotes the improvements in aerodynamics and engine technology that contribute to this efficiency. This increased fuel efficiency leads to lower operational costs over the lifespan of the aircraft, making it an attractive option for airlines looking to reduce their carbon footprint and operating expenses.

In contrast, the other options do not reflect the advancements made with the A320neo. Claiming that it consumes more fuel or has no significant changes overlooks the innovations that directly contribute to fuel savings. Additionally, while the A320neo may accommodate longer flight ranges due to its improved efficiency, the primary focus of the design change is the enhanced fuel economy.
