Gulfstream G280 vs Gulfstream G450
The Gulfstream G280 and the G450 both carry the Gulfstream name, but they arrived from different engineering origins and address different missions. The G280 (2012 certification) was developed by Israel Aerospace Industries as the G250 — a super-midsize jet with Honeywell HTF7250G engines and a design independent from the classic Gulfstream lineage. Gulfstream acquired rights to the program and certified it as the G280, producing a contemporary aircraft with efficient turbofan economics, modern avionics, and approximately 3,600 nm range in a cabin sized for eight passengers. The G450 (2004) is a classic Gulfstream large-cabin aircraft — Rolls-Royce Tay 611-8C engines, fourteen to nineteen passengers in a wide, stand-up cabin, and transatlantic range well beyond the G280's. The cross-shop occurs at the boundary of super-midsize and large-cabin, where the question is whether the G450's cabin and range justify its operating costs over the more economical G280.

Which Should You Buy: Gulfstream G280 or Gulfstream G450?
Bottom line: Choose the G280 for super-midsize economics and contemporary avionics — the Honeywell HTF7250G engines are modern designs with solid efficiency, and the G280's lighter weight keeps per-hour costs meaningfully below the G450. For eight or fewer passengers on missions under approximately 3,500 nm, the G280 does the job without the G450's fuel burn and maintenance overhead. Choose the G450 when the cabin defines the mission — the G450's stand-up cabin, flat floor, and larger passenger volume deliver a different experience than the G280, and its range enables transatlantic operations the G280 cannot cover with a full payload. Safety axis: both types require Gulfstream type ratings at an approved training facility. The G450's Rolls-Royce Tay engines have an exceptional in-service reliability record over two decades of operation, and the G450's large fleet provides deep MRO access worldwide. The G280's shorter production history means a smaller fleet and somewhat less independent MRO infrastructure; Gulfstream-authorized service is more important for G280 support than for the established G450 platform.
Pick the G280 if…
- Lower operating cost — ~$3200/hr vs $3600/hr.
- Newer design — production from 2012 vs 2004.
Pick the G450 if…
- Budget matters — from $3,944,760 vs $12,119,000, you save ~$8,174,240.
- More seats — 16 vs 10.
- Faster cruise — 476 kts vs 459 kts.
- Longer range — 4350 nm vs 3600 nm.
- More inventory — 36 listings vs 22.
