Gulfstream G450 Overview (2005-2018)

Product Overview

The Gulfstream G450 is a direct descendent of the Gulfstream G400/GIV-SP series. It comes with upgraded engines (Rolls-Royce Tay 611-8C) with FADEC, and redesigned thrust reverser, nacelle and pylon that, coupled with aerodynamic improvements, increase range and payload. It was designed using the G400 airframe with the G550 nose section grafted on, and the fuselage is 12 inches longer than the Gulfstream IV.

As of May 2021, 60% of all Gulfstream G450 aircraft were purchased pre-owned by their current owners, the other 40% new. 7.3% are for sale with the majority of those (92%) under an exclusive broker agreement. When for sale the average time on the market is 288 days.
