G450 vs G500

The G500 leads, topping 6 of 7 compared metrics.

Cross-shopping the Gulfstream Aerospace G450 (introduced 2005) against the Gulfstream Aerospace G500 (introduced 2018) 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 range, where the G500 has the advantage. Below we compare them spec by spec, then break down which aircraft suits which mission.

G450 vs G500: the key differences

  • The G500 delivers 20% more range (G450: 4,350 nm; G500: 5,200 nm).
  • The G500 delivers 6% more cruise speed (G450: 459 kt; G500: 488 kt).
  • The G500 delivers 19% more passenger capacity (G450: 16 seats; G500: 19 seats).
  • The G500 is the newer design (introduced 2018 versus 2005 for the G450), a gap of 13 years that usually shows up in avionics, cabin systems and fuel burn.
  • The G500 is the larger aircraft by maximum takeoff weight (91,400 lbs versus 74,600 lbs), which typically buys more cabin and payload at the cost of higher trip economics.

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 G500 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?

On published specifications the G500 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The G450 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
