Gulfstream reinvents the large cabin class with the all-new G400

Gulfstream recently introduced a new private jet: the G400. The aircraft, which sits between the super-midsize G280 and the large-cabin G500, is the company’s reimagined large-cabin jet and the first to enter the category for more than a decade.

The new G400 was unveiled on October 4 in a live-streamed launch ceremony at Gulfstream headquarters in Savannah, Georgia. The special event included a virtual tour of the new G400, which showed us a glimpse of the improved interior of the aircraft.

“The aircraft reimagines this market segment with its maximum operational flexibility and improved cabin comfort”, says Gulfstream President Mark Burns.

The interior of the G400 is strategically sized, with floor plans that can offer up to 2.5 living spaces. Depending on the floor plan, the aircraft can accommodate nine, 11 or 12 passengers.

People will benefit from the fresh air with the Gulfstream Cabin Experience and the lowest cabin altitude in their respective classes. Other features include 10 panoramic oval windows and a plasma ionization clean air system capable of neutralizing airborne bacteria and odors.

Powered by advanced Pratt & Whitney PW812GA engines, the aircraft is capable of reaching 4,200 nautical miles (4,833 miles / 7,778 km) at a cruising speed of Mach 0.85. Being one of the fastest planes in its class, it can reach a top speed of 0.9 Mach.

The G400 features a clean-wing aerodynamic design, which dramatically reduces fuel consumption, emissions and noise.

Technically, Gulfstream outfitted the jet with advanced avionics such as the Symmetry Flight Deck, which includes electronically linked active throttles (a company first) that increase non-verbal communication between pilots through tactile signals. In addition, intensive use of touch screens reduces pilot workload and flight start-up time.

The cockpit includes a predictive landing performance system that uses real-time data, allowing pilots to make the necessary adjustments to help prevent runway excursions.

Gulfstream expects customer deliveries for the G400 to begin in 2025.
