Falcon 900LX vs G400

The G400 leads, topping 4 of 7 compared metrics.

Cross-shopping the Dassault Aviation Falcon 900LX (introduced 2010) against the Gulfstream Aerospace G400 (introduced 2023) is a common decision, and the two sit closer on paper than the badges suggest. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is cabin capacity, where the G400 carries more passengers. We line the numbers up below, then translate them into the mission each aircraft actually wins.

Falcon 900LX vs G400: the key differences

  • The Falcon 900LX delivers 13% more range (Falcon 900LX: 4,750 nm; G400: 4,200 nm).
  • The G400 delivers 4% more cruise speed (Falcon 900LX: 459 kt; G400: 476 kt).
  • The G400 delivers 36% more passenger capacity (Falcon 900LX: 14 seats; G400: 19 seats).
  • The G400 is the newer design (introduced 2023 versus 2010 for the Falcon 900LX), a gap of 13 years that usually shows up in avionics, cabin systems and fuel burn.
  • The G400 is the larger aircraft by maximum takeoff weight (74,600 lbs versus 49,000 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
  • The two differ in powerplant layout: the Falcon 900LX runs 3 engines against 2 on the G400 — a factor in redundancy, maintenance scope and operating cost.

Which mission suits which aircraft

Both aircraft are built for long-haul and transatlantic missions, so outright range rarely separates them — the call leans on cabin (the G400 seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.

Which should you choose?

Choose the Falcon 900LX when nonstop range is the deciding factor, and the G400 when cabin capacity and payload matter more; the G400 holds the cruise-speed edge. The right answer ultimately depends on acquisition cost, maintenance-program status, and what is actually available on the market — talk to our acquisition advisory team to pressure-test the choice against your missions and budget.
