GULFSTREAM G450
Gulfstream G450 for Sale: The GIV Refined for Long-Range Ownership
The 2004 Classic Refined
The Gulfstream G450 grew out of the GIV-SP, but the important date is 2005, not 2004. Gulfstream started flight testing in April 2003, received FAA certification in August 2004, and delivered the first G450s after the aircraft entered service in May 2005. Production ended in January 2018.
Gulfstream was updating a proven large-cabin platform for a new generation of buyers. The G450 received Rolls-Royce Tay 611-8C engines, FADEC, aerodynamic changes and the Honeywell Primus Epic PlaneView cockpit. The forward fuselage was also redesigned around the G550 cockpit section, while the fuselage grew by 12 inches compared with the GIV.

Gulfstream G450 Competitors
Bombardier Challenger 605 for sale / Range: 4,123 nm maximum published range, with 10 executive seats in AvBuyer's buyer guide.
The Challenger 605 is smaller and lighter. Its cabin is 28 ft 4 in long and 7 ft 11 in wide, while the G450 has a much longer cabin. The 605 uses GE CF34-3B engines and Collins Pro Line 21 avionics.
If cabin size and long-range capability are high on the list, the G450 is the more natural choice. If the mission is closer to 4,000 nm and operating economics matter more, the Challenger deserves a serious look.
Dassault Falcon 900EX for sale / Range: 4,725 nm maximum, with 4,500 nm published for the full-seat range figure.
The Falcon 900EX uses three Honeywell TFE731-60 engines and carries 12 passengers in the cited configuration. Its cabin volume is around 1,218 to 1,270 cu ft, well below the G450's published 1,523 cu ft figure on GlobalAir.
The reason buyers compare these aircraft is simple. Both can cover long international missions. The G450 gives you a larger cabin and two Tay engines. The Falcon brings the three-engine Falcon design and a different airport and operating profile.
Bombardier Global 5000 for sale / Range: 5,200 nm with full payload in Bombardier's published brochure, with a 5,984 nm maximum figure listed by GlobalAir.
The Global 5000 has a 7 ft 11 in wide cabin, 6 ft 2 in height and 40 ft 9 in cabin length. It also cruises faster than the G450 in some published profiles and has a 51,000 ft maximum operating altitude.
The Global 5000 is the step-up option when the mission regularly pushes beyond the G450's range. Current market listings also show that older Global 5000s can overlap with G450 asking prices, which makes the comparison particularly important.
Embraer Legacy 650 for sale / Range: 3,900 nm maximum, with 3,661 nm listed at full payload.
The Legacy 650 has a long cabin, almost 50 ft according to GlobalAir, but it is narrower and lower than the G450. It seats up to 14 in the cited configuration and uses Rolls-Royce AE3007A2 engines.
For a buyer who flies shorter international routes and wants a large cabin without moving into G450 size, the Legacy 650 is worth comparing. Its range is the first limitation to check.

The Verdict
The G450 is still a very capable large-cabin jet for the buyer whose normal trips fall around the 2,000 to 4,000 nm mark.
Its advantage is easy to understand. You get a large Gulfstream cabin, Rolls-Royce Tay engines, PlaneView avionics and roughly 4,400 nm of published maximum range in a mature used-aircraft platform.
The honest limitation is age. Maintenance status, engine coverage and avionics configuration can make one G450 a much better purchase than another.
If the mission is eight passengers and roughly 2,500 to 3,000 nm, I would put the G450 on the shortlist and then compare specific aircraft by records, engine status, avionics and total acquisition cost.
