Embraer E-Jet E2 family The Embraer E-Jet E2 family is a family of three narrow-body medium-range twin-engine jet airliners developed by Brazilian aerospace company Embraer, replacing the predecessor Embraer E-Jet family. The three variants share the same fuselage cross sections with different lengths and three different new wings, Pratt & Whitney PW1000G geared turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin with 40% enlarged baggage bins. Announced improvements per seat are 16 to 24% lower fuel burn and 15–25% lower maintenance cost.

Aircraft in the series include the ERJ135 (37 passengers), ERJ140 (44 passengers), and ERJ145 (50 passengers), as well as the Legacy business jet and the R-99 family of military aircraft. Each jet in the series is powered by two turbofan engines. The family's primary competition comes from the Bombardier CRJ regional jets.
