The Gulfstream G650ER is the long-range private jet of choice for many of the world’s wealthiest individuals, such as Elon Musk and Jeff Bezos.
However, the brand new Gulfstream G800 presents a compelling option for wealthy individuals, all while being the longest-range private jet on the market.
Therefore, what are the key differences between these two aircraft? And which should you choose?
Performance
Both the Gulfstream G650ER and G800 are equipped with a pair of Rolls-Royce engines.
Rolls-Royce engines are known for their reliability, efficiency, and high thrust output. Therefore, it is no surprise that Rolls-Royce engines are used to power some of the fastest business jets with long-range capabilities, such as the Cessna Citation X, Global 5500, and most Gulfstream aircraft.
The G650ER is powered by two Rolls-Rouce BR725 engines, while the G800 is powered by two rear-mounted Pearl 700 engines.
In terms of thrust output, the G800 outperforms the G650ER with a total thrust output of 36,500 lbs (16,556 kg) compared to the G650ER’s 33,800 lbs (15,329 kg).
When it comes to the cruise speed of these two aircraft the figures are identical both in terms of high-speed cruise and long-range cruise numbers.
Both the Gulfstream G650ER and Gulfstream G800 are capable of cruising at up to Mach 0.90 and both have a long-range cruise speed of Mach 0.85.
Both aircraft have the same maximum altitude of 51,000 feet (15,545 meters) and initial cruise altitude of 41,000 feet (12,497 meters).
A higher maximum altitude offers several advantages, such as better fuel efficiency due to less air resistance, smoother rides as a result of flying above turbulent weather, and reduced noise pollution as the aircraft is farther away from ground-based noise sources.
Range
The Gulfstream G650ER and Gulfstream G800 are both long-range private jets, capable of covering vast distances without refueling.
The G650ER has a range of 7,500 nautical miles (13,890 kilometers), while the G800 boasts an impressive range of 8,000 nautical miles (14,816 kilometers).
These range figures represent the best-case scenario, assuming optimal conditions and minimal payload.
It is important to note that the actual range of these aircraft can be affected by several factors.
Firstly, weather conditions such as headwinds or tailwinds can significantly impact the range, as strong headwinds require more fuel consumption to maintain the desired speed.
Secondly, the weight of the payload, including passengers, luggage, and onboard amenities, will also influence the range. A heavier payload requires more fuel to lift and maintain altitude, thus reducing the overall range.
Lastly, air traffic control restrictions and routing requirements may necessitate a less direct flight path, increasing the total distance traveled and affecting the range.
If both aircraft were to take-off from New York City then it is possible to fly non-stop to all of North America, South America, Europe, Africa, and most of Asia.
Ground Performance
Given the size of these two aircraft and the range performance, the ground performance figures are extremely impressive for such large aircraft.
The G650ER has a take-off distance of 6,299 feet (1,920 meters). In comparison, the G800 boasts a slightly shorter take-off distance of 6,000 feet (1,829 meters).
In the real world, a 300-foot difference in take-off distance will likely be noticed at some airports. However, in most mission profiles this will be unlikely to be a deciding factor.
A shorter take-off distance is beneficial as it allows the aircraft to operate from smaller airports with limited runway lengths, providing greater flexibility in choosing departure and arrival locations.
This, therefore, means that it is possible to arrive and depart from airports closer to your final destination. This will therefore reduce overall travel time.
When it comes to the ground performance figures of private jets the take-off distance is considered more important as it is almost always greater than the landing distance.
Moreover, the landing distance for the Gulfstream G800 is currently unknown. However, for the G650ER the minimum landing distance comes in at 3,000 feet (914 meters)
It is crucial to note that these take-off and landing distances represent the best-case scenario and may be influenced by various factors.
The take-off and landing distance will mostly be effected by weight, which includes the payload, fuel, and onboard equipment. Heavier aircraft require longer distances to reach the necessary speed for take-off or decelerate during landing.
Another factor is the runway surface condition, as wet or icy runways can increase the required take-off and landing distances due to reduced traction. Lastly, environmental factors such as wind direction and strength, temperature, and altitude can also impact the ground performance of an aircraft, as they affect aerodynamics, engine performance, and braking efficiency.
Interior Dimensions
The Gulfstream G650ER and G800 both offer spacious and luxurious interiors, ensuring a comfortable and enjoyable travel experience for their passengers.
The G650ER and Gulfstream G800 have the exact same width and height, measuring 8.17 feet (2.49 meters) and 6.27 feet (1.91 meters) respectively.
However, the G650ER has a longer cabin with a total interior length of 53.58 feet (16.34 meters) versus 46.82 feet (14.28 meters) of the Gulfstream G800.
A longer cabin provides numerous benefits, such as increased space for seating, more room for amenities like conference tables or entertainment systems, and additional storage capacity for luggage and personal items.
The benefits of a wider cabin include enhanced passenger comfort through increased seat width and aisle space, allowing for easier movement throughout the cabin. Additionally, a wider cabin can accommodate larger windows, providing ample natural light and better views during the flight.
The primary benefit of a taller cabin is that it is easier for passengers to stand-up straight and move around the cabin. Moreover, it makes the cabin feel more spacious.
In terms of passenger capacity, the G650ER can accommodate up to 19 passengers in its maximum configuration and typically seats 16.
The G800, on the other hand, can also hold up to 19 passengers in its maximum configuration but typically seats 15.
Interior
One are that is often overlooked when comparing aircraft is the maximum cabin altitude.
A lower cabin altitude offers several benefits for passengers, particularly in terms of comfort and well-being.
Firstly, a lower cabin altitude helps to reduce the effects of jet lag, as the body is exposed to less stress from the lower oxygen levels typically experienced at higher altitudes. This means that passengers can arrive at their destination feeling more refreshed and alert.
Secondly, a lower cabin altitude also contributes to better air quality and humidity levels inside the cabin, reducing the likelihood of dryness and discomfort in the eyes, nose, and throat.
Gulfstream is the leading manufacturer in terms of keeping a low cabin altitude and maintaining a sea-level cabin for as long as possible.
The G650ER has a maximum cabin altitude of 4,100 feet (1,250 meters) and can maintain a sea level cabin up to an altitude of 31,900 feet (9,723 meters).
Unfortunately, the specific figures for the G800’s maximum cabin altitude and sea level cabin maintenance altitude are not available. However, it will likely be the same as the G650ER.
Gulfstream G650ER
Of course, the G650ER has a fantastic interior as expected with a Gulfstream. The interior is identical to that of the standard G650.
The G650ER boasts a spacious interior – described as “a refined getaway above the clouds”. The cabin can have up to four living areas, enough to work, dine, entertain, and relax.
With one of the quietest cabins in business aviation, the G650ER is the perfect place to relax. The G650ER has a cabin noise level of just 47 decibels. A cabin altitude of 4,100 feet is the lowest in business aviation. 4,100 feet is the cabin altitude when cruising at 51,000 feet. However, it is important to note that when cruising below 51,000 feet the cabin altitude is even lower.
These two factors combine to guarantee that the G650ER is supremely comfortable. Additionally, low cabin noise and 100% fresh air ensure that you will arrive at your destination with minimal jet lag.
With 16 of the trademark Gulfstream large, oval windows provide the cabin with an abundance of natural light.
Providing both comfort and productivity, Gulfstream’s handcrafted seats allow you to settle in and enjoy the journey. Each seat is positioned next to a window.
When circumnavigating the globe, as expected, the G650ER is able to provide fully flat beds for passengers. All single seats and divan convert to beds, providing you with a good night’s sleep.
Flying on the G650ER entitles you to top-of-the-range cabin amenities. Expect WiFi connectivity, a 42-inch flatscreen TV, video monitors, and extensive galley facilities.
