Gulfstream unveils the comfortable G400 and long range G800
Thursday, 7 October 2021
The G800 is the longest range aircraft in Gulfstream history and will be powered by Rolls-Royce Pearl 700 engines, while the G400 aims for comfort and high speed, with PW812GA Pratt & Whitney engines.

Gulfstream Aerospace has introduced two new aircraft, the G800, the longest range aircraft in its history, powered by Rolls-Royce Pearl 700 engines, and the G400, with the Pratt & Whitney Canada PW800 powerplant.

Gulfstream announced the new aircraft before a live audience at its Savannah, Georgia headquarters along with a global broadcast via its website, Facebook and YouTube. The exclusive event featured a virtual tour of the new G400 and a live reveal of the first G800.

“For more than six decades, Gulfstream has led the business aviation industry with our commitment to continuous improvement and by consistently setting new standards for safety, performance, innovation and comfort,” says Mark Burns, president, Gulfstream. “Today marks a major milestone and investment in our company's future with the introduction of the G800, our fastest longest range aircraft yet, and the G400, the industry's first new large-cabin aircraft in more than a decade.”

The G800 offers customers the longest range in the Gulfstream fleet 14,816 km range at Mach 0.85 and 12,964 km at Mach 0.90. Powered by high thrust Rolls-Royce Pearl 700 engines and using the Gulfstream designed wing and winglet introduced on the Gulfstream G700, the G800 also features enhanced fuel efficiency and more city pair capabilities.

The G800 is designed to seat up to 19 passengers and offers up to four living areas or three living areas with crew compartment. It also features the signature Gulfstream cabin experience with 100% fresh, never recirculated air, quiet noise levels, low cabin altitude and 16 panoramic oval windows.

Dual head up displays in the G800 feature Gulfstream's new combined vision system that unites the enhanced flight vision system and synthetic vision system into a single image, increasing pilot situational awareness and access to more airports worldwide.

The Rolls-Royce Pearl 700 engine type has been custom built for Gulfstream and is on track to receive its certification next year. It is the most powerful product in the Rolls-Royce business jet propulsion portfolio and the exclusive powerplant for the new Gulfstream G700 and G800.

“Gulfstream is pleased with the performance capabilities of the Pearl 700 engine and excited to partner with Rolls-Royce for the longest range aircraft we have produced,” continues Burns. “Gulfstream and Rolls-Royce have been doing business together since the Gulfstream I, introduced more than 60 years ago, and we know our customers will greatly benefit from the performance capabilities and efficiencies of these engines.”

Dr Dirk Geisinger, director business aviation, Rolls-Royce, adds: “The Pearl 700 is a pioneering product that brings together our latest technology to deliver outstanding efficiency. It is part of our commitment to reach net zero operations and has already proved its ability to run on 100% sustainable aviation fuel. We are now in the final phase of the engine certification programme and everybody at our team is fully committed to support a smooth entry into service of the Pearl 700 next year.”

The G400 offers a combination of long range, high speed performance, cabin comfort and environmental efficiency.

It increases environmental performance by reducing fuel consumption, emissions and noise through its use of its aerodynamic clean wing design and advanced Pratt & Whitney PW812GA engines. The aircraft will fly 7,778 km at its long range cruise speed of Mach 0.85. Three floorplans are offered, with options for seating up to nine, 11 or 12 passengers and the G400 provides the signature Gulfstream cabin experience and 10 panoramic windows.

Pratt & Whitney Canada will deliver a fully integrated powerplant solution comprised of the PW812GA engine and nacelle system provided by Collins Aerospace. The PW812GA extends the application of the PW800 architecture, with optimisations for the advanced requirements of the G400 aircraft including the latest full authority digital engine control, sophisticated technology to support engine health monitoring and the use of advanced materials such as titanium and composites to deliver superior performance and availability.

“We are delighted that Gulfstream has once again turned to our engine family to power this new addition to its portfolio,” says Maria Della Posta, president of Pratt & Whitney Canada. “Gulfstream was the launch customer for the PW800 engine family, when the PW814GA powered G500 entered into service in September 2018, followed by the PW815GA powered G600 in August 2019. The PW800 engine on the G400 will bring a new level of performance and efficiency to the large cabin business aircraft class.”

Both the G800 and G400 are equipped with the Gulfstream Symmetry flight deck featuring electronically linked active control sidesticks and 10 touchscreen displays.

Additional health and safety enhancements include a plasma ionising clean air system neutralising 99.9% of airborne bacteria, spores and odours; and its predictive landing performance system, providing pilots advanced warning of potential runway excursions so they can adjust approaches or go around.

G800 customer deliveries are anticipated to begin in 2023 and G400 deliveries are expected in 2025.
