Both the Gulfstream G600 and Dassault Falcon 6X are powered by Pratt & Whitney Canada engines, a renowned firm known for manufacturing reliable and efficient engines.

The Gulfstream G600 is powered by the PW815GA model, while the Dassault Falcon 6X utilizes the PW812D model.

In terms of thrust output, the Gulfstream G600 outperforms the Dassault Falcon 6X.

Each engine of the G600 generates 15,680 lbs (7,111 kg) of thrust, making a total thrust output of 31,360 lbs (14,223 kg).

On the other hand, each engine of the Falcon 6X produces 13,500 lbs (6,123 kg), giving it a total thrust output of 27,000 lbs (12,247 kg).

Both jets boast a high-speed cruise of 516 knots (954 km/h), providing fast and efficient travel.

However, the long-range cruise speed of the G600 is 488 knots (904 km/h), which is higher than that of the Falcon 6X at 458 knots (848 km/h).

A higher cruise speed means you can reach your destination quicker, which is beneficial for time-sensitive travel.

When it comes to altitude, both aircraft can reach a maximum of 51,000 feet (15,545 meters). The initial cruise altitude of the G600 is 41,000 feet (12,497 meters), while the Falcon 6X starts cruising at an even higher altitude of 43,000 feet (13,106 meters).

A higher maximum altitude allows the aircraft to fly above most weather disturbances, ensuring a smoother and more comfortable flight experience.

Fuel consumption is an essential factor to consider when comparing these two aircraft.

The Gulfstream G600 consumes 458 gallons (1,733 liters) of fuel per hour, while the Dassault Falcon 6X has a lower fuel burn rate of 419 gallons (1,586 liters) per hour.

Selecting an aircraft with a lower fuel burn rate translates into significant cost savings.

Assuming Jet A fuel costs $6 per gallon, flying each aircraft for 300 hours per year would result in a saving of $70,200 with the Falcon 6X due to its lower fuel burn rate.


The range of a private jet is a crucial consideration for potential owners or charterers.

In the case of the Gulfstream G600 and the Dassault Falcon 6X, there is a significant difference in their respective ranges.

The G600 boasts a range of 6,600 nautical miles (12,230 kilometers), while the Falcon 6X offers a range of 5,500 nautical miles (10,186 kilometers).

This means that both aircraft are capable of flying non-stop from New York to all of Europe and the Middle East.

However, as the map below shows, the G600 is able to fly to considerably more destinations non-stop. For example, the G600 can fly non-stop from New York to Tokyo, something that the Falcon 6X simply cannot do.

These figures represent best-case scenarios and are subject to several influencing factors.

Firstly, the weight of the aircraft, inclusive of passengers, luggage, and fuel, can impact the range. A heavily loaded plane will consume more fuel, reducing its range.

Secondly, weather conditions play a role. Strong headwinds can increase fuel consumption, decreasing the range, while tailwinds can extend it.

Lastly, the cruising altitude can affect an aircraft’s range. Higher altitudes often provide thinner air, reducing air resistance and thus increasing fuel efficiency and range.

Ground Performance

When comparing the ground performance of the Gulfstream G600 and the Dassault Falcon 6X, it becomes apparent that both aircraft are designed for efficiency and precision.

The take-off distance for the Gulfstream G600 is 5,700 feet (1,737 meters), while the Dassault Falcon 6X requires slightly less runway at 5,480 feet (1,670 meters).

On landing, the Gulfstream G600 needs 3,100 feet (945 meters) to come to a complete stop, whereas the Falcon 6X requires just 2,480 feet (756 meters).

This presents a clear advantage of the Falcon 6X due to the benefits that come with shorter take-off and landing distances.

Naturally, these are the best-case scenario figures and in many real-world situations, a difference in minimum take-off distance of 220 feet is unlikely to be too significant.

In terms of shorter take-offs and landings, there are numerous benefits.

Firstly, they allow these aircraft to operate out of smaller airports. This gives passengers access to a wider range of destinations, including those that might be closer to their final destination, reducing travel time.

Secondly, shorter take-off and landing distances also mean these aircraft are capable of operating in more challenging environments, such as high-altitude airports or those with shorter runways due to geographical constraints.

This adds to the versatility and utility of these aircraft, making them a valuable asset for any business or private owner.

These figures represent the best-case scenario and actual performance may vary based on several factors.

One of these is the weight of the aircraft, which includes fuel, passengers, and luggage. A heavier aircraft will require more runway to gather the necessary speed for take-off and will need a longer distance to decelerate upon landing.

Weather conditions can also impact ground performance, with factors like wind direction and speed, temperature, and air pressure all playing a role. For instance, headwinds can help reduce take-off and landing distances, while tailwinds can increase them.

Lastly, the condition of the runway is an influencer. A wet or icy runway can increase the distance needed for take-off and landing, while a dry, well-maintained runway can keep these distances to a minimum.

Interior Dimensions

The interior dimensions of a private jet significantly contribute to the comfort and overall experience of the passengers. When it comes to the Gulfstream G600 and the Dassault Falcon 6X, both jets offer spacious cabins but with notable differences.

The Gulfstream G600 boasts an interior length of 51.25 feet (15.61 meters), which is longer than the Falcon 6X’s length of 40.35 feet (12.30 meters). A longer cabin provides more space for passengers to move around freely, enhancing their comfort during long flights. It also allows for additional amenities and seating configurations, making the journey more enjoyable.

In terms of width, the Falcon 6X offers a slightly wider cabin at 8.46 feet (2.58 meters) compared to the G600’s width of 7.58 feet (2.31 meters). A wider cabin can provide passengers with more personal space, which is particularly beneficial on crowded flights or during long hauls when passengers might want to stretch out or rest.

The Falcon 6X also has a slightly taller cabin, standing at 6.50 feet (1.98 meters) in height, compared to the G600’s height of 6.17 feet (1.88 meters). A taller cabin allows for more headroom, which is especially advantageous for taller passengers. It also gives the cabin a more spacious and airy feel, which can enhance the overall travel experience.

The maximum passenger capacity for the Gulfstream G600 is 19, with a typical configuration accommodating 16 passengers.

On the other hand, the Falcon 6X can carry up to 16 passengers at its maximum capacity, with a typical setup accommodating 14 passengers.


The cabin altitude of a private jet is an essential factor that directly influences the comfort and well-being of passengers, especially during long-haul flights. When we look at the Gulfstream G600 and the Dassault Falcon 6X, there are noticeable differences in their respective cabin altitudes.

The Gulfstream G600’s maximum cabin altitude is set at 4,850 feet (1,478 meters), which is lower than the Falcon 6X’s maximum cabin altitude of 6,000 feet (1,829 meters).

A lower cabin altitude results in a higher atmospheric pressure inside the cabin. This higher pressure allows for more oxygen to be absorbed in the blood, reducing symptoms related to altitude sickness such as headaches, shortness of breath, and fatigue.

Consequently, passengers tend to feel more comfortable and less fatigued after flying, especially on longer flights.

Gulfstream G600

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.

Dassault Falcon 6X

The Falcon 6X has a truly stunning cabin. The latest in technology and comfort have been integrated to maximize passenger comfort.

Firstly, the 6X has a tall and wide cabin. According to Dassault, the 6X has the tallest and widest cabin in any purpose-built business jet. This gives you more space to sit or stand. It also provides more room for privacy and relaxation. Additionally, common space has been allocated in order to allow teams to meet and confer. Dassault have built the cabin to be flexible between living and working space. This allows you to stay comfortable while achieving more.

The air filtration system on the Falcon 6X keeps you breathing easier and gets fresh air into your lungs. The entire volume of cabin air can be refreshed in under three minutes. Furthermore, Dassault have been able to make the interior of the cabin have some of the lowest sound levels on the market. According to Dassault, the sounds levels are “below the level of normal conversation”.

The 6X has 30 large windows throughout the cabin. Windows are closely spaced to increase the field of view when looking out the window. The volume of natural light entering the cabin is sure to elevate your mood and enlarge your perspective. Incredibly, Dassault have managed to integrate a skylight into the cabin. The first ever in a business aircraft. This drenches the entrance and galley areas in natural light.

A critical aspect of business jets in their connectivity to the outside world. The cabin can be controlled from your own personal device, allowing you to control lighting, volume level and entertainment options. The connectivity onboard will make you feel like your at your own home or office.

Charter Price

When it comes to chartering these two aircraft, the hourly price is estimated to be the same.

Both the Gulfstream G600 and the Dassault Falcon 6X are estimated to cost $10,000 per hour when chartering. This parity in price offers potential customers a choice between two high-quality aircraft without the need to factor in differing costs.

However, it’s important to note that the hourly charter cost is just one aspect of the overall expense associated with private jet hire.

here are several other factors that can influence the total cost. One of these is the duration of the flight. Longer flights will naturally incur higher costs due to increased fuel consumption and possibly additional crew requirements.

The destination also plays a role. Flights to remote or challenging locations may be priced higher due to the added complexity and risk involved.

Purchase Price

The acquisition cost of a private jet, whether new or pre-owned, is a significant financial consideration for potential owners. Looking at the Gulfstream G600 and the Dassault Falcon 6X, we find some differences in their pricing structures.

The new list price for the Gulfstream G600 stands at $54,500,000, while the Dassault Falcon 6X is priced slightly lower at $47,000,000. These figures represent the cost to acquire a brand-new model of either aircraft.

In terms of pre-owned models, a 2019 Gulfstream G600 has an estimated market value of $54,000,000. This, therefore, results in an annual depreciation rate of just 0.43% for the Gulfstream G600.

This is an unprecedented figure and means that if you were to buy a 2019 G600 today and sell it in 3 years, you would be able to sell if for just over $53 million. As aa result, you would likely lose less than $1 million in depreciation during your ownership time.

When it comes to private jets, this is an incredibly impressive number.

Unfortunately, the Falcon 6X does not have any market data to compare with the G600. However, it will be hard to beat.

Several factors can influence the depreciation rate of a private jet.

These include the aircraft’s age, as older jets tend to depreciate faster. Maintenance history also plays a role, as well-maintained aircraft maintain their value better. Finally, market conditions can impact depreciation, with higher demand leading to slower depreciation rates.


So, which aircraft is best?

The Gulfstream G600 can fly further than the Falcon 6X. It can also fly faster with more passengers and with an overall larger cabin. Moreover, the cabin altitude is far lower than the 6X. This likely results in a more pleasant cabin environment.

However, the G600 costs more to buy than the 6X. It also costs more to operate annually than the 6X, partly due to burning more fuel per hour.

Additionally, the Falcon 6X has better ground performance figures meaning that it can operate from more airports than the G600.

If you are choosing between these aircraft the decision is easy should you be wanting to fly non-stop from New York to Tokyo given the 6X can’t complete this mission.

However, if all your missions will fall within the range of both aircraft, then the decision will come down to availability, money, and which interior you prefer.

Moreover, we cannot ignore the loyalty that many customers have to their chosen manufacturers.
