Aircraft comparison: Gulfstream G700 versus Bombardier Global 7500

We always start our aircraft comparisons with a disclaimer, and this time is no different. The Gulfstream G700 was announced the day before this article was originally written, whereas the Global 7500 has seen its first handful of deliveries.

When this comparison was originally written, the G700 was just a day old, having only been announced the night before. Announcements of major specification changes, such as a bump in range, have become increasingly common. The Global 7500, the aircraft that we will compare to the G700, saw a range increase of 300nm before its first delivery.

The flagship aircraft in both manufacturers’ fleets are respectively the biggest and second-biggest purpose-built business jets. Both have ranges that can connect city pairs like Los Angeles to Sydney or Beijing to Cape Town.

Both aircraft, on paper at least, look similar but are born from different DNA. The Gulfstream G700 continues from the 500+ selling G650 which revolutionised business aviation with its speed and range, and the Global 7500, one of the most anticipated business jets ever, with the longest range and longest cabin in the industry.

But things can and do change. The Global 7500 (then known as the Global 7000) was originally launched by Bombardier back in October 2010 and took until the end of 2018 to enter service. Gulfstream announced the G700 in October 2019 and said that the first aircraft will be in the hands of launch customer Qatar Executive in 2022.

Price:

Gulfstream G700: $75 million
Global 7500: $72.8 million

You could argue that a difference of $2.8 million when spending over $70 million on an aircraft is not such a big difference, in fact, the G700 is just 3% more expensive than the Global 7500.

However, $75 million hits a psychological barrier. Even if you are a billionaire, 72.8 can be a much easier number to swallow than 75.

Cabin length:

Gulfstream G700: 56ft 11in
Global 7500: 54ft 5in

The G700 and the Global 7500 are the biggest purpose-built business jets and, as such, have massive cabin volume. Although the fuselage of the Global 7500 is longer than the G700, the cabin of the G700 is longer, taller and wider.

Both aircraft can carry a maximum of 19 people, although the G700 cabin layout can be completed to have five separate zones, whereas the Global 7500 can currently only have four.

Maximum Range:

Gulfstream G700: 7,500nm
Global 7500: 7,700nm

There is only a 200nm range difference between the two aircraft, with the Global 7500 winning this round. As noted earlier, Bombardier found an extra 200nm of range before the first Global 7500 was delivered, so there is always a chance that Gulfstream will do the same with the G700, as it did with the G280, G450, G500, G600 and G650.

That is of course unless Gulfstream is planning an extended range ER version of the G700 further down the line, much as it did with the G650.

It is also worth mentioning that whilst the quoted maximum range of the Global 7500 is 7,700nm, in early October 2019 a Global 7500 flew non stop between Detroit and Sydney. That’s just over 8,200nm, making it the longest flight ever recorded by a purpose-built business jet.

Maximum Speed:

Gulfstream G700: Mach 0.925
Global 7500: Mach 0.925

According to the manufacturers websites, both aircraft have identical max speed, high-speed cruise and long-range cruise speeds.

Take off distance:

Gulfstream G700: 6,250ft
Global 7500: 5,800ft

Using the figures that manufacturers have supplied for the take off distance each aircraft needs at Maximum Take Off Weight (MTOW), then the Global 7500 is the clear winner as it needs 450ft less of runway to get airborne.

Unfortunately, the landing distance that the G700 is not currently known, however, the Global 7500 needs 2,850ft.

Gulfstream has a track record of not only delivering on its promises when it launches a new aircraft, but often exceeding them. So with all specs for the Gulfstream G700 not yet released, it is hard to make a true comparison between the two aircraft.

But on paper at least, before the final specifications are known, the Global 7500 is less expensive and flies further. The G700, on the other hand, has a larger cabin.
