The Gulfstream G600 and G700 are two of the newest aircraft from the Savannah, GA, based manufacturer.
These two aircraft represent the latest and greatest in comfort, technology and design.
However, how do these two aircraft actually differ? Furthermore, which aircraft should you choose to charter or even buy?
Firstly, it is important to consider the difference in performance between these two aircraft. Of course, as the names suggest, the G700 is the larger of the two aircraft. Therefore, it will come as no surprise that the Gulfstream G700 has more thrust than the G600.
The Gulfstream G600 is powered by two Pratt & Whitney Canada PW815GA engines. Each engine is capable of producing up to 15,680 lbs of thrust. As a result, the total thrust output for the G600 is 31,360 lbs.
On the other hand, the Gulfstream G700 is powered by two Rolls-Royce Pearl 700 engines. Each engine is capable of producing up to 18,250 lbs of thrust. As a result, the total thrust output for the G700 is 36,500 lbs.
However, despite the additional thrust of the Rolls-Royce engines, the G700 and G600 have the same maximum cruise speeds. Both the G600 and G700 are able to cruise at up to 516 knots.
Furthermore, the similarities continue when it comes to cruise altitude. Both the Gulfstream G600 and G700 are able to cruise at up to 51,000 feet.
An area where these two aircraft do differ, however, is hourly fuel burn. Please note that these figures are based off preliminary data.
In terms of hourly fuel burn, the G600 is estimated to burn 458 Gallons per Hour (GPH). In comparison, the G700 is estimated to burn 382 Gallons per Hour (GPH).
This is a surprising difference given that not only is the G700 a larger, heavier aircraft, it also has more powerful engines.
The G600 is capable of flying up to 6,600 nautical miles (7,595 miles / 12,223 kms) without needing to refuel.
In comparison, the G700 is capable of flying up to 7,500 nautical miles (8,631 miles / 13,890 kms) without needing to refuel.
That’s a substantial difference in range. For reference, based off these figures, the G600 is able to fly non-stop from New York to New Delhi, India.
In comparison the G700 is able to nearly make it non-stop from New York to Bangkok, Thailand, without needing to refuel.
Of course, as with every manufacturer stated range figures, these numbers are somewhat optimistic. Therefore, once you factor is passengers, baggage and weather conditions, these aircraft will not be achieving these figures.
However, that isn’t to take away from these breathtaking range figures.
When it comes to performance on the ground, the competition is surprisingly close.
The Gulfstream G600 has a minimum take off distance of 5,700 feet. In comparison the Gulfstream G700 has a minimum take off distance of 6,250 feet.
Given the additional size and weight of the G700, a difference of just 550 feet is impressive.
Furthermore, the official minimum landing distance figures are even more impressive.
The G600 has a minimum landing distance of 3,100 feet. Whereas the minimum landing distance of the G700 is 2,500 feet.
Amazingly, the larger G700 is able to safely land in a shorter distance than its smaller sibling.
As has been said many times in this comparison, the Gulfstream G700 is a bigger aircraft than the Gulfstream G600. Therefore, when comparing their interior dimensions, the results are not surprising.
Consequently, one of the most notable differences between the G600 and G700 is the interior length. When it comes to interior length, the G600’s cabin measures 15.62 meters long. In comparison, the G700’s measures 17.35 meters in length.
Next up is interior width.The G600’s cabin measures 2.31 meters in width. In comparison, the G700’s cabin measures 2.49 meters wide.
Finally, cabin height. The G600’s cabin measures 1.88 meters in height. For reference, the G700 measures 1.91 in interior height.
As you can see, in every measurable way, the G700 is larger than the G600. This results in larger seats, a larger aisle and greater space for distinct living areas.
However, despite the G700 being a larger aircraft, Gulfstream claim that both aircraft can accommodate up to 19 passengers each. Of course, it is unlikely that these aircraft will ever be flying at maximum occupancy.
And finally, baggage capacity. The G600 can accommodate 175 cubic feet of luggage. Meanwhile, the G700 has space for up to 195 cubic feet of baggage.
Again, this should come as no surprise. What this means is that the baggage limit for each passenger is far greater when flying the G700 compared with the G600.
Both of these aircraft are extremely new. Some of the newest aircraft in the sky. For reference, deliveries of the G600 began in 2019, compared with deliveries of the G700 starting in 2022.
This freshness continues through to both cabins. In fact, even the maximum cabin altitude is the same for both aircraft.
When cruising at 51,000 feet, both the G600 and G700 will have a cabin altitude of just 4,850 feet.
The benefit of a lower cabin altitude is a more pleasant cabin environment and reduced effects of jet lag. For reference, a typical airliner has a cabin altitude of around 8,000 feet. And this is when cruising at a far lower altitude.
The G600 interior is designed for passengers to relax, work and dine in. The G600 has been designed by Gulfstream to “be the quietest [cabin] in business aviation”. This is hardly surprising as the whole Gulfstream family of aircraft has exceptionally quiet cabins. Additionally, the G600 features Gulfstream’s classic 100% fresh air system. Combine this with the low cabin altitude will ensure that you arrive at your destination refreshed.
Furthermore, Gulfstream has been able to fit in fourteen signature Gulfstream oval windows. These windows are “the largest in business aviation” and drown the interior in natural light. The size and placement of the windows also offer all passengers a fantastic view of the world below.
Onboard passengers will be sitting on award-winning seats. These seats blend style, functionality, and comfort all into one. Gulfstream has been able to utilize customer feedback and optimize the proportions of the seat for an ideal fit. Through using precise, computerized machining, Gulfstream has been able to eliminate pressure points for maximum comfort.
The G600 can be configured with up to four living areas. Within the four living areas, there is space for up to 19 passengers and space for up to 10 passengers to sleep.
The G600 is so luxuriously appointed that it has even been awarded the International Yacht & Aviation Design Award.
According to Gulfstream, the G700 features the tallest, widest and longest cabin in the industry. If you require a larger cabin you will be looking at the VIP airliners, such as the Boeing Business Jet (BBJ) or Embraer Lineage 1000E.
The aim of the G700 is to create the most comfortable environment possible in the sky so that you can sleep, work or relax as efficiently as possible. The G700 features true circadian lighting to simulate the sunlight of your next time zone to help reduce the effects of jet lag. Additionally, the G700 has a maximum cabin altitude of just 4,850 feet, one of the lowest cabin altitudes to be found on a private jet, helping you sleep better and reduce the effects of jet lag. Add in the extremely quiet cabin, you will have no trouble working, sleeping, or just relaxing.
Gulfstream has also fitted the G700 with twenty of the largest windows in business aviation, flooding the cabin with natural light to make the already large cabin feel even more spacious. As standard, the G700 features Jet Connex Ka-band Wi-Fi so that you can stay connected when you are in the air for hours at a time. The G700 features an all-new seat design that is handcrafted for each aircraft and can be converted to ergonomic beds.
The G700 has a maximum capacity of 19 passengers in a seating configuration and space for 13 passengers in a sleeping configuration. The cabin can be configured with up to five living spaces so you will always be able to get some privacy from your fellow passengers when on a long flight. See below for the various configurations you can have on a G700.
When it comes to chartering these aircraft the G600 is less expensive than the G700. However, please note that there are many factors that influence the price of a private jet charter. Therefore, prices will vary depending on the mission.
The estimated hourly charter price of the G600 is $10,000 .
In comparison, the estimated hourly charter price of the G700 is $13,000.
Please do keep in mind that these prices are estimates only. There are a variety of factors that can and will influence the charter price of a private jet.
And finally, how much does each aircraft cost to buy?
The Gulfstream G600 has a new list price of $54.5 million. In comparison the Gulfstream G700 has a new list price of $75 million.
Usually at this point we would compare the pre-owned value of each aircraft. Unfortunately, due to the newness of these aircraft that isn’t possible.
However, historically speaking, Gulfstream aircraft are exceptionally good at retaining their value. Therefore, it is likely that both the G600 and G700 will retain a strong percentage of their value.
So, which of these two aircraft is best?
Ultimately, the reason to choose the G700 over the G600 is the additional cabin space and greater range ability.
However, the decision starts to get harder when you factor in the Gulfstream G650ER. The G650ER has the same range as the G700. Moreover, there are plenty of pre-owned examples of the G650ER on the market that represent a better value proposition. This is important to consider given that around 85% of all private jets are purchased pre-owned.
See a comparison between the G650ER and G700 here.
Therefore, when comparing the G600 and G700, the G600 provides nearly everything that the G700 can but for less.
Realistically, the only area that the G700 outperforms the G600 is range. In this circumstance one would have to consider whether the additional $20 million price tag is worth it.
Additionally, if you do require the extra range then would the G650ER not suit your needs just as well as the G700 but for less?
