NEW HORIZONS
Discover a breakthrough formula for 21st-century business success. Reaching a maximum range of 4,200 nm/7,778 km1 at Mach 0.85 cruise, the G400 delivers you to farther destinations, faster. Travel nonstop from Geneva to New York, or São Paulo to Miami, while accruing significant time savings through the year.

TOTAL EFFICIENCY
The G400 ramps up environmental performance on an intercontinental scale. Advanced twin Pratt & Whitney engines reduce fuel consumption, emissions and noise. The iconic Gulfstream aerodynamic clean-wing design further optimizes fuel-efficiency.


TAILORED FOR COMFORT
The G400 offers the largest cabin in its class. Optimal floorplans provide up to 2.5 living areas, so you have flexible space for meetings, focused work and relaxation. Thrive in an environment of 100% fresh air—replenished every two minutes—and a low cabin altitude, so you arrive refreshed.

Relax
Designed to be exceptionally quiet, the G400 cabin provides a peaceful environment.

Bask
Ten windows—the largest in business aviation—offer abundant natural light and sweeping views of the world.

ADVANCED AVIONICS
Gulfstream’s award-winning Symmetry Flight Deck has revolutionized the way that pilots operate, vastly improving safety and efficiency. Active control sidesticks increase nonverbal communication between pilots through tactile cues. The industry’s most extensive use of touch-screen displays, paired with Phase-of-Flight intelligence, reduces pilot workload and flight start-up time.

SAFETY INNOVATION
Our award-winning Predictive Landing Performance System uses real-time data to increase pilots’ situational awareness on approach. With continuously updated data, pilots can make the necessary micro-adjustments to help prevent runway overruns.
