Boeing seems well on its way to unveiling the redesigned 737, dubbed the 737 MAX. Now that they have the basic design finalized, Boeing's engineer will begin ironing out the aircraft's finer details.
What's different about the new 737 is its fuel consumption. Gone are the days of four-engine jumbo jet awesomeness. With fuel prices ever on the rise, airlines needed a narrow-bodied airliner that gets better fuel economy than the jets in their current fleets. The 737 MAX weighs less than its predecessor, uses new CFM LEAP-1B engines, and benefits from improved aerodynamics.
