The Bombardier Global 7500 and Global 8000 are ultra long-range business jets under development by Bombardier Aerospace, announced in October 2010 and initially scheduled for introduction in 2016 for the 7500 and 2017 for the 8000. The program has been delayed by two years and entry into service for the Global 7500 is expected in 2018. The 7500, originally named the 7000, made its first flight on November 4, 2016.

Design
Both are stretched derivatives of the Global 6000 with a new transonic wing. They are powered by the new General Electric Passport 20 16,500 lbf (73 kN) thrust engine with reduced NOx emissions and 8% better fuel efficiency than the Global Express XRS, allowing a Mach 0.90 high-speed cruise. As part of its effort to make the long-range aircraft comfortable for the passengers, Bombardier developed a new ergonomic passenger seat, called the Nuage. The seat design took seven years to complete.
Global 7500
Officially designated as the BD-700-2A12, the design is marketed as the Global 7500. It is stretched by 11 ft 3 in (3.43 m) from the original Global. It is planned to have a four-zone 2,637 cu.ft. (74.67 cu.m.) cabin, 20 percent more than the previous. It was originally designed to cover a 7,300 nmi (13,500 km) range at Mach 0.85 to fly from London to Kuala Lumpur, New York to Dubai, or Beijing to Washington non-stop with 10 passengers.
Global 8000
BD-700-2A13, marketed as the Global 8000, is stretched by 2 ft 3 in (0.69 m) from the Global Express. It will feature a three-zone 2,236 cu.ft. (63.32 cu.m.) cabin and a range of 7,900 nmi (14,631 km) at Mach 0.85, farther than any other existing business jet and connecting Sydney to Los Angeles, Hong Kong to New York, and Mumbai to New York with eight passengers.

Development
In 2015 Bombardier decided to redesign the aircraft's wing and, along other development challenges, Bombardier delayed the programme by over two years. The goal of the redesign was to reduce the wing's weight without altering its aerodynamic profile. The aircraft fly-by-wire system architecture is based on the CSeries one. The airframe will use Aluminium-lithium alloys like the new airliner.
Global 7500
Formerly named Global 7000, its entry into service was initially scheduled for 2016. Former Formula One driver and long time Bombardier brand ambassador Niki Lauda announced his order ahead of the EBACE 2015 convention.
The first test aircraft underwent taxi testing in October 2016, with the first delivery scheduled for the second half of 2018. Dedicated to testing basic system functionality and assessing the handling and flying qualities of the aircraft, its maiden flight was performed on November 4th 2016, climbing to 20,000 feet (6,096 m) and reaching 240 knots during 2 h 27 mn.
The production wing was in final design in February 2017 and was expected to fly on a production-conforming airplane later in the same year. FTV2 flew on March 6, 2017, "The Powerhouse" is designed to test aircraft systems, including propulsion, electrical and mechanical systems. FTV1 is used to open the performance envelope and reached Mach 0.995 on March 29, 2017. FTV3 flew on May 10, 2017, "The Navigator" will be used to test the avionics and electrical system performance. At the end of May 2017, the three prototypes have flown a combined 250h.
The fourth prototype, used for cabin interior validation, is called "The Architect" and the fifth and final, used to pave the way for the entry-into-service, is called "The Masterpiece". The fifth has a slightly lighter production wing supplied by the Triumph Group, after a dispute over the wing weight was resolved.
By mid-July 2017, the three flight-test aircraft had accumulated 500 hours. On 15 August 2017, after "high vibration and high inter-turbine temperature readings", the second prototype's right GE Passport had an in-flight flameout at FL410 and the aircraft went back in Wichita Airport 156nm (290km) away for a single engine landing.
By October 2017, the four flight-test aircraft had flown 900 hours and the fifth will fly another 700 to 800 hours before the type's entry into service in the second half of 2018.
In April 2018, the flight test campaign surpassed 1,800h and confirmed a range increase from 7,400 to 7,700 nmi (13,700 to 14,300 km), greater than the competing Gulfstream G650ER's 7,500 nmi (13,900 km), but still overshadowed by the smaller Global 8000's range of 7,900 nmi (14,600 km), 200 nmi (370 km) more than the Global 7500. As the original Global Express is developed into the Global 5500 and 6500, it is renamed Global 7500 to reflect this range increase.
By the end of May 2018, the five flight-test aircraft had amassed about 2,000 hours towards the type's planned entry-into-service at year-end. By June 2018, 2,300 flight test hours had been completed by the test fleet towards certification. The first production aircraft entered the completion centre in May 2018, on track to enter service in the second half of the year.
Global 8000
Entry into service was initially scheduled for 2017. The programme schedule is delayed over two years, pushing Global 8000 deliveries to early 2019. Trading nearly 8 ft (2.4 m) of cabin space for 600 nmi (1,100 km) of range, the Global 8000 accounted for a very small part of the backlog in December 2017 and its schedule should be determined after the Global 7500 enters service. Lacking differentiation, it could be replaced by a higher MTOW Global 7000 variant with more range.
Orders
While Bombardier is not publishing a specific backlog, industry analyst Rolland Vincent estimated that 200 orders had accumulated by the time of the first flight in November 2016, mostly for the 7500 version.
