The 757 was intended to be more capable and more efficient than the preceding 727.The focus on fuel efficiency reflected airline concerns over operating costs, which had grown amid rising oil prices during the Yom Kippur War of 1973. Design targets included a 20 percent reduction in fuel consumption from new engines, plus 10 percent from aerodynamic improvements, versus preceding aircraft. Lighter materials and new wings were also expected to improve efficiency. The maximum take-off weight (MTOW) was set at 220,000 pounds (99,800 kg), which was 10,000 pounds (4,540 kg) more than the 727. The 757's higher thrust-to-weight ratio allowed it to take off from short runways and serve airports in hot and high conditions with higher ambient temperatures and thinner air, offering better takeoff performance than that offered by competing aircraft. Competitors needed longer takeoff runs for these hot and high conditions. Boeing also offered options for higher payload capability.
Production of the 757 peaked at an annual rate of 100 aircraft in the early 1990s, during which time upgraded models came under consideration. For over a decade, the narrow-body twinjet had been its manufacturer's only single-aisle airliner without a stretched variant, and while rumors of a long-range 757-200X and stretched 757-300X persisted, no formal announcements had been made. European charter carriers were particularly interested in a higher-capacity version which could take better advantage of the 757's range. Besides meeting the needs of charter customers, a larger model would enable Boeing to match the passenger lift capabilities of the 767-200 with lower operating costs,[66] and counter longer-range versions of the 185-seat Airbus A321, a new stretched variant of the A320 narrow-body airlinerCeiling

he 757 is a low-wing cantilever monoplane with a conventional tail unit featuring a single fin and rudder. Each wing features a supercritical cross-section and is equipped with five-panel leading edge slats, single- and double-slotted flaps, an outboard aileron, and six spoilers.
While the 757 program had been financially successful, declining sales in the early 2000s threatened its continued viability.
