Gulfstream G500 Vs Gulfstream G650

Gulfstream G500 Exterior

The Gulfstream G650 is one of the most iconic Gulfstream’s that is currently cruising the skies. However, the Gulfstream G500 is one of the most modern Gulfstream aircraft, with deliveries having started in 2018.

Therefore, how do these aircraft stack up against each other? One of the newest Gulfstream aircraft against a nearly 10 year old flagship.

Performance

Firstly, let’s look at the performance of each aircraft.

The Gulfstream G500 is powered by two Pratt & Whitney Canada PW814GA engines. Each engine is capable of producing up to 15,144 lbs of thrust. As a result, the total thrust output for the G500 is 30,288 lbs.

On the other hand, the Gulfstream G650 is powered by two Rolls-Royce BR725 engines. Each engine is capable of producing up to 16,900 lbs of thrust. As a result, the total thrust output for the G650 is 33,800 lbs.

Of course, this difference in thrust comes as no surprise considering that the G650 is a larger aircraft.

However, when it comes to the cruise speed of each aircraft, the difference in thrust is academic. Both the G500 and G650 are capable of cruising at up to 516 knots.

Additionally, both aircraft are evenly matched when it comes to their maximum cruise altitude. Both aircraft are capable of cruising at up to 51,000 feet.

However, an area where technology and efficiency put the G500 ahead of the older G650 is fuel burn.

The G500 has a fuel burn of just 353 Gallons per Hour (GPH). In comparison, the G650 burns 475 Gallons per Hour (GPH).

At $5 per Gallon of Jet A fuel, the cost saving is substantial. Therefore, on average, the G500 will cost you $520 less in fuel per hour compared with the G650.

Range

However, when it comes to maximum range, the G650 easily beats the G500.

The G500 is capable of flying up to 5,300 nautical miles (6,099 miles / 9,816 kms) without needing to refuel.

In comparison, the G650 is capable of flying up to 7,000 nautical miles (8,055 miles / 12,964 kms) without needing to refuel.

A difference in range of 1,700 nautical miles is substantial. This will result in some missions being easily completed with the G650 while the G500 will need to stop to refuel.

Of course, as with every manufacturer stated range figures, these numbers are somewhat optimistic.

Ground Performance

Ground performance is not a surprise. Given that the G500 is a smaller aircraft than the G650, you would expect it to require less runway. And, of course, that is true.

The Gulfstream G500 has a minimum take off distance of 5,300 feet. In comparison the Gulfstream G650 has a minimum take off distance of 5,858 feet.

However, the two aircraft are surprisingly close is minimum landing distance – with a difference of just 82 feet. Given the additional size of the G650, that is extremely impressive performance.

The G500 has a minimum landing distance of 3,100 feet. Whereas the minimum landing distance of the G650 is 3,182 feet.

Interior Dimensions

There is no getting around the fact that the G650 is a larger aircraft than the G500. However, the difference isn’t as stark as one might first expect. Rather, the G650 is just slightly bigger in all aspects.

For example, when it comes to interior length, the G500’s cabin measures 14.5 meters long. In comparison, the G650’s measures 16.33 meters in length.

Next up is interior width.The G500’s cabin measures 2.31 meters in width. In comparison, the G650’s cabin measures 2.49 meters wide. Again, the difference in size is relatively minor. Just a few percent.

Finally, cabin height. The G500’s cabin measures 1.88 meters in height. For reference, the G650 measures 1.91 in interior height.

As a result, the G650 will afford each passenger more space in every dimension. The aisle is slightly wider and there is more headroom. Therefore, the G650 will be a more pleasant cabin environment in regards to space.

Despite the slightly smaller dimensions of the G500, Gulfstream claim that both aircraft can carry the same number of passengers. Both the G500 and G650 can accommodate up to 19 passengers. However, as always with maximum passenger figures, it is unlikely that either aircraft will every fly with every seat occupied.

And finally, baggage capacity. Again the figures are not surprising. The G500 can accommodate 175 cubic feet of luggage. Meanwhile, the G650 has space for up to 195 cubic feet of baggage.

Interior

When comparing two private jets, an important factor to consider is cabin altitude. This is especially true when comparing long range jets.

The benefits of a lower cabin altitude are a more pleasant cabin environment and reducing the effects of jet lag. Therefore, the lower the cabin altitude, the better. And, for many, many years, Gulfstream have been the masters at achieving a low cabin altitude.

Of course, the G500 and G650 are no exception. When cruising at 51,000 feet, the maximum cabin altitude of the G500 is just 4,850 feet compared with a maximum cabin altitude of 4,100 feet for the G650.

Therefore, despite the G500 being the newer, more modern aircraft, the G650 still has a lower cabin altitude.

Gulfstream G500

As with every Gulfstream, the G500 is wonderfully appointed. All the features you would expect on a long-range business aircraft are provided.

To begin with, the G500 has a tall and wide cabin which provides customers with greater design flexibility. For example, customers are presented with the option for a forward galley, rear gallery and a rear stateroom.

The tall and wide cabin provides lots of space for strolling down the wide aisle. All-new seats have been designed for maximum comfort.

100% fresh air, a maximum cabin altitude of 4,850 feet, and a cabin noise level of 50 decibels provide a peaceful environment. This environment is lit by fourteen signature Gulfstream oval windows. Combined, these windows provide an abundance of natural light and sweeping views of the world below. Adding these factors together ensures that you arrive at your destination refreshed and with minimal jet lag.

Gulfstream’s Cabin Management System allows passengers to control lighting, temperature, and media right from their seats. The seats are able to be converted to lie-flat beds. Therefore, the G500 is a great space to work, dine and relax.

Gulfstream G650

Of course, the G650 has a fantastic interior as expected with a Gulfstream.

The G650 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 G650 is the perfect place to relax. The G650 has a cabin noise level of just 47 decibels. A cabin altitude of 4,100 feet is the lowest in business aviation.

These two factors combine to guarantee that the G650 is supremely comfortable. Additionally, low cabin noise, low cabin altitude, 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 G650 is able to provide fully flatbeds for the passengers. All single seats and divan convert to beds, providing you with a good night’s sleep.

Flying on the G650 entitles you to the top-of-the-range cabin amenities. Expect WiFi connectivity, a 42-inch flatscreen TV, video monitors, extensive galley facilities.

Charter Price

When it comes to chartering these aircraft the Gulfstream G500 is less expensive than the G650. 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 G500 is $7,350 .

In comparison, the estimated hourly charter price of the G650 is $10,500.

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.

Purchase Price

And finally, how much does each aircraft cost to buy?

The Gulfstream G500 has a new list price of $45 million. In comparison the Gulfstream G650 has a new list price of $65 million.

However, the purchase price of these aircraft starts to get really interesting when looking at their pre-owned value.

According to Aircraft Bluebook, a two year old G500 will set you back $42 million.

Therefore, the G500 will see a 93% retention of value over the same time period.

In comparison, a eight year old G650 is estimated to cost $56 million.

This, therefore, results in the G650 will see a 86% retention of value over the same time period.

Therefore, the Gulfstream G500 represents a better ‘investment’ thanks to its less aggressive depreciation curve. Additionally, in terms of the cash value, while the G650 will lost $9 million in value over two years, the G500 will only lose $3 million.

Summary

So, which aircraft is better? Should you choose the G500 or G650?

Much like when comparing the G500 with the G550 or the G600 with the G650, Gulfstream have been extremely clever about their aircraft lineup.

If one aircraft is unable to achieve your mission, then you can easily step up to a more capable aircarft.

Therefore, the conclusion of this summary is that if the G500 fits your needs, then that is the aircraft to choose. However, if you need the additional range, then the G650 is the aircraft to go for.

However, if you are looking to purchase one of these aircraft, the G500 represents the better deal.
