Summary The Gulfstream G600 carries 11.3% more payload (6,540 lbs) than the G550, with the same seating capacity. The G600 cabin is 11% larger (1,884 cubic ft) than the G550, allowing for more comfort and a crew rest area.
The Pratt & Whitney engines on the G600 provide a higher cruise speed (Mach 0.9) for shorter travel times. The Gulfstream G550 and the G600 are large business jets designed for long-range flying for up to 19 passengers each.
The successor G600 hit the market in 2019, while the predecessor G550 has proven performance. This article notes specific upgrades Gulfstream made to the G600 jet. 1 Payload capacity The Gulfstream G600 has over 11% more payload capacity Both the Gulfstream G550 and G600 share the same external dimensions.
However, the G600 has 11% greater payload capacity than the G550. With a capacity of 6,540 lbs, the G600 can carry slightly more fuel and more payload. While both types have a limit of up to 19 passengers, they are generally configured for 12-16 passengers.
According to GlobalAir , “With a 2024 list price of $54.5 million, the Gulfstream G600 epitomizes luxury and performance in private aviation. Whether for business or leisure, the Gulfstream G600 promises an unparalleled flying experience that is second to none.
” Over 250 variants are currently in service today. 2 Increased cabin volume The Gulfstream G600 cabin volume is over 11% greater than the G550 The Gulfstream G600 features a more spacious cabin. Despite the same external dimensions, Gulfstream upgraded the cabin, having a volume of 1,884 cubic ft compared to 1,669 cubic ft on the G550.
The additional nearly-2 m cabin length enables up to four individual cabin sections compared to three on the G550. According to Gulfstream , “Designed to be the quietest in business aviation, the cabin provides a peaceful environment. Arrive alert and refreshed thanks to 100% fresh air and an exceptionally low cabin altitude.
” Gulfstream states that the G600 features 14 windows in the cabin, which is the largest in business aviation. The large windows offer abundant natural light and sweeping views of the world. Examining one of the fastest business jets on the market.
3 Crew rest area The longer cabin of the G600 allows more space The Gulfstream G600’s lengthier cabin provides sufficient space for an additional luggage area, a fourth living area, or a crew rest area. The dedicated crew rest areas can make all the difference with the aircraft’s long-range (for flights as long as 16 hours). According to Gulfstream , “At its near-supersonic high-speed cruise of Mach 0.
90, the G600 has more than enough range to connect far-flung cities like New York and Dubai, London and Beijing, or Los Angeles and Shanghai nonstop. As an added bonus, fewer flight hours means longer periods between scheduled maintenance visits, higher potential aircraft value and fresher crews.” Not so much an upgrade but a trade-in.
4 Power Plants Pratt & Whitney engines power the G600 The Gulfstream G600 is powered by two Pratt & Whitney Canada PW815 turbofan engines, each generating 15,680 lbf (70 kW) of takeoff power. The engines are slightly more powerful than the G500 Rolls-Royce BR710 engines. The G600 engines support the aircraft's greater Maximum Takeoff Weight (MTOW) and enable greater cruise speeds.
Gulfstream claims that the improved operating speeds minimize flight time while ensuring high operational reliability. The Gulfstream G600 has been in service since August 2019. 5 Operating speed The Gulfstream G600 cruises at a much greater speed than the G550.
The Pratt & Whitney PW800 engines offer much greater speed on the G600 than the G550 offered. The near-supersonic speed means shorter travel times for the passengers and their guests. Moreover, the inherent airframe and engine design minimizes wave drag at transonic speeds.
While the high-speed cruise may reduce the maximum range achieved, the efficient systems provide optimized fuel efficiency based on the configuration. The G600 has been in production since August 2019..
