The Boeing 757-300
 

Engines and Wings

Boeing 757-300 in flightThe 757-300 and 757-200 share many of the same features. Both have high-bypass-ratio engines and a wing design that help make them two of the quietest, most fuel-efficient jetliners in the world.

Engines are available from Rolls-Royce or Pratt & Whitney in thrust ratings of 43,500 (193.5kN) and 42,600 pounds (189.4kN) respectively.

The wings on both the 757-300 and 757-200 are less swept and thicker through the center than those on earlier Boeing airplanes, permitting a longer span. The lower wing surface is slightly flatter, and the leading edge is somewhat sharper. This improves lift, reduces drag and makes for improved aerodynamic efficiency and low fuel consumption.

The only difference between the 757-300 and the 757-200 wing is that the former has been structurally reinforced to handle the increased load.
