Keeping the same fuselage cross-section, longer variants are stretched by up to 14 ft (4.3 m) from the DC-9-50 and have a 28% larger wing.The larger variants (MD-81/82/83/88) are 148 ft (45.1 m) long to seat 155 passengers in coach and, with varying weights, can cover up to 2,550 nautical miles [nmi] (4,720 km; 2,930 mi). The later MD-88 has a modern cockpit with Electronic flight instrument system (EFIS) displays. The MD-87 is 17 ft (5.3 m) shorter for 130 passengers in economy and has a range up to 2,900 nmi (5,400 km; 3,300 mi).The MD-80 series initially competed with the Boeing 737 Classic and then also with the Airbus A320ceo family. Its successor, introduced in 1995, the MD-90, was a further stretch powered by IAE V2500 high-bypass turbofans, while the shorter MD-95, later known as the Boeing 717, was powered by Rolls-Royce BR715 engines. Production ended in 1999 after 1,191 MD-80s were delivered, of which 116 aircraft remain in service as of August 2022.
