The ultimate competition between two of the most luxurious, most capable private jets in the sky – the Gulfstream G650ER Vs the Gulfstream G700. Both aircraft have similar stats, costs and capabilities.
Therefore, how do you choose one over the other?
The G700 is Gulfstream’s latest aircraft development, with deliveries to customers due to begin in 2022. The G650ER has been around since 2014, with the G650 – the platform that the G650ER is based – having been around for a decade.
Is it as simple as one is newer? How do you decide the best one to charter? Is it worth purchasing a G650ER pre-owned for less than a new G700? All these questions and more will be answered in this instalment of aircraft comparisons. To view all our other aircraft comparisons then please click here.
Firstly the performance data will be assessed. Factors such as cruising speed, range and runway performance will be discussed. Next the interiors will be analyzed. Finally the costs – both charter and purchase – will be compared.
Firstly, cruise speed. This is a metric that is easy to understand and compare. Additionally, the cruise speed of an aircraft is vitally important when flying long distances. If one aircraft cruises at 450 knots and another at 500, over a distance of 7,000 Nautical Miles that will translate to an increased journey time of 1 and a half hours.
When comparing the G650ER and G700 they are equally matched for their cruise speed. Both aircraft can cruise at a speed of 516 Knots. Keep in mind that this is the true airspeed of the aircraft – the speed of the aircraft relative to the air mass through which it is flying. However, in terms of mach, both aircraft can cruise at 0.90 mach. For reference, Mach 1 is the speed of sound.
In terms of the maximum speed of the aircraft, both aircraft have a Maximum Operating Mach Number (Mmo) of Mach 0.925.
Range is a similar story to cruise speed when comparing these aircraft. Both aircraft have a maximum range of 7,500 Nautical Miles (8,631 Miles / 13,890 KM) one a single tank of fuel.
This means that both aircraft can fly non-stop from New York to Hong Kong or Seattle to Sydney. For reference, both aircraft are able to achieve this range when cruising at 0.85 Mach.
Gulfstream G650ER Vs Gulfstream G700 Take Off Distance
The take off distance is where the numbers start to diverge with the G700 taking the crown, but only just.
The Gulfstream G650ER has a minimum take off distance of 6,299 feet. The G700 is able to beat this by just 49 feet, with a minimum take off distance of 6,250 feet.
In the real world will this difference be noticeable? Probably not. However, the benefit of a shorter take off distance is that the aircraft is able to reach more airports. Although it is unlikely that there will be a situation in which the G700 can reach an airport that the G650ER can’t.
However, these numbers are an interesting comparison between the aircraft. The G700 has the same range as the G650ER. Can achieve the same speeds. The G700 is also a larger aircraft. So the fact that Gulfstream have been able to develop the G700 to have a shorter take off distance than the G650ER – even if it is slight – is an impressive feat of engineering.
Gulfstream G650ER Vs Gulfstream G700 Landing Distance
The figures are even more pronounced when looking at the landing distance of both aircraft.
The G650ER has a minimum landing distance of 3,000 feet. An impressive figure for an aircraft that is so large and capable. However, once again, the G700 beats this. The G700 has a minimum landing distance of just 2,500 feet.
The Gulfstream G700 can land in 500 feet less than the G650ER.
Again, in the real world will this be noticeable? And again the answer is no. The reason for this is because whichever airport you land at you have to take off from. Therefore, to land at an airport that you can’t take off from isn’t particularly useful. However, it once again highlights the impressive engineering and technological advancements that have gone in the G700.
Gulfstream G650ER Vs Gulfstream G700 Capacity
Both aircraft can carry up to 19 passengers. This is hardly a surprise given the fact that the G700 is the flagship aircraft for Gulfstream, with its predecessor being the G650ER.
However, the primary purpose of these aircraft is to fly long haul routes. Therefore, the number of people that can sleep onboard is vital. This is where the G700 is able to trump the G650ER. The G700 has space for up to 13 passengers to sleep, with each passenger having a fully flat bed. The G650ER, on the other hand, can only accommodate up to 10 passengers in a sleeping configuration. Again, with each passenger having a fully flat bed.
The interiors of both aircraft are classic Gulfstream. However, this is where the extra size of the G700 will be most appreciated. Both cabins of the G650ER and G700 are the same width and height. Both a 2.49 meters wide and 1.91 meters height. This makes both cabins easy to move around in and provide plenty of shoulder room. The difference is length. The G650ER has an interior cabin length of 16.33 meters versus the 17.35 meter length of the G700. This enables the G700 to have up to five living areas, compared with up to four living areas in the G650ER.
The G650ER has space for up to four living areas, providing enough space to work, dine, entertain and relax. The cabin noise level comes in at just 47 decibels, making it one of the quietest cabins in the sky. When cruising at 51,000 feet the cabin altitude is just 4,100 feet. Lower than most other jets at lower altitudes. Bear in mind that when cruising at lower altitudes the cabin altitude is even lower.
Combine these two factors and you have a supremely comfortable cabin. And, as you would expect from a Gulfstream, 100% fresh air is constantly entering the cabin. The entire volume of air in the cabin can be replaced with 100% fresh air in just a few minutes. Sixteen of Gulfstream’s large oval windows run along the side of the cabin.
According to Gulfstream, the G700 features the tallest, widest and longest cabin in the industry. 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.
Compared with the 16 windows on the G650ER, the G700 features 20 of the signature Gulfstream windows. As standard the G700 features Jet Connex Ka-band Wi-Fi so that you can stay connect when you are in the air for hours at a time.
Seeing as the G700 is a larger and newer aircraft than the G650ER, you would expect the G700 to cost more to charter. And that is exactly correct.
While the G700 is yet to be available for charter, current figures suggest that the estimated hourly charter rate of the G700 will be $13,000 per hour. The G650ER, on the other hand, is estimated to cost $10,900 per hour.
If you are to split if by passenger in a seating configuration then the G650ER costs less. However, if you split it by the sleeping passenger configuration the G700 comes out cheaper. Per passenger in a sleeping configuration, the G700 would cost $1,000 per hour. Alternatively, the G650ER would cost $1,090.

Gulfstream G650ER Vs Gulfstream G700 Purchase Price
Much like with the charter price, the same story continues for the purchase price. The base list price for the G700 is $75 million. The base list price for the G650ER is $70 million.
Moreover, if you were to consider pre-owned examples, a G650ER can be had for as little at $40 million for a three to four year old aircraft. All things considered, that’s a lot of aircraft for the price.
So, Which is Best?
The G650ER is at an inherent disadvantage in this comparison.The G700 is far newer. A newer aircraft brings new technology and improvements over the previous generation.
Therefore, objectively looking at the figures the G700 is a better aircraft. The G700 can fly just as far, just as fast, and has a bigger, more comfortable cabin.
However, consider the fact that deliveries of the G650, of which the G650ER is based, started ten years ago, with deliveries of the G650ER starting in 2014. And yet the G650ER can keep up with the G700 and match it on almost every comparative measure, it is still one of the most capable and luxurious private jets out there.
