Gulfstream G650ER vs Gulfstream G700
The Matchup
This is the Gulfstream family feud. The G650ER is the reigning champion — the aircraft everyone benchmarks against. The G700 is the new flagship, offering more cabin and newer technology. If you're a Gulfstream loyalist (or just shopping the best ultra-long-range jets), this comparison comes down to whether the G700's extra cabin justifies a potentially massive price premium.
Head to Head
| Gulfstream G650ER | Spec | Gulfstream G700 |
|---|---|---|
| 7,500 NM at Mach 0.85 | Range | ★7,750 NM at Mach 0.85 |
A 250 NM advantage. Meaningful on paper but rarely decisive in practice. Both cover virtually every ultra-long-range city pair you'd need. | ||
| Mach 0.925 | Max Speed | ★Mach 0.935 |
The G700's Pearl 700 engines push it to Mach 0.935 — the fastest in business aviation alongside the Global 8000. On a 7,000 NM flight, the speed difference saves roughly 10–15 minutes. Nice to have, not a deal-maker. | ||
| 8 ft 6 in★ | Cabin Width | 8 ft 2 in |
Surprise — the older jet is actually wider. Four inches matters in seat comfort and lie-flat bed width. The G650ER's cross-section is one of the widest in business aviation. | ||
| 46 ft 10 in | Cabin Length | ★56 ft 11 in |
Ten feet longer. This is the G700's defining advantage. Five living zones instead of three. A proper master stateroom. Crew rest area. On flights over 10 hours with 8+ passengers, this extra space fundamentally changes the experience. | ||
| 6 ft 5 in★ | Cabin Height | 6 ft 3 in |
Two inches taller. Minor but noticeable for passengers over 6 feet. | ||
| 13–19 | Passengers | 13–19 |
Same maximum capacity. The G700's longer cabin makes higher passenger counts more comfortable, though typical configurations seat 13–15 in both. | ||
| 51,000 ft | Ceiling | 51,000 ft |
| 6,299 ft | Takeoff Distance | 6,250 ft |
Within 50 feet — no meaningful operational difference. | ||
| 3,000 ft | Landing Distance | 2,937 ft |
Again, negligible difference. | ||
| 2× Rolls-Royce BR725 (16,900 lbs thrust each) | Engines | ★2× Rolls-Royce Pearl 700 (18,250 lbs thrust each) |
The Pearl 700 is the next-generation engine — more thrust, better fuel efficiency, cleaner emissions. It's also newer with less field history, but Rolls-Royce's track record inspires confidence. | ||
| $45.95M–$47.9M asking — 2016 examples | 2026 Acquisition Market Reference | $73.38M–$82M Vref (July 2026) |

G700
If you regularly fly with 8+ passengers, staff, or family — and you want everyone in separate zones — the G700's five-zone, 57-foot cabin is unmatched. The G650ER's three zones feel compact by comparison.

Aircraft age, condition and maintenance commitments can outweigh an apparent model-level price advantage.
G650ER
For 1–4 passengers, the G700 is dramatically more aircraft than you need. The wider cabin of the G650ER is actually more comfortable for small groups, and you're not paying to heat, cool, and maintain 57 feet of cabin for four people.
G700
Symmetry Flight Deck with active control sidesticks, Pearl 700 engines, latest cabin management systems, lower cabin altitude. If having the newest, most advanced cockpit and cabin technology matters — and for some buyers it absolutely does — the G700 is the clear choice.
G650ER
The math is simple. The G650ER offers equivalent range, a wider cabin, lower operating costs, and dramatically lower acquisition costs. For the vast majority of ultra-long-range missions, the G650ER is the smarter purchase.
The Final Take
The G700 is objectively the better aircraft — longer cabin, newer engines, more advanced avionics, slightly more range and speed. If money were no object and you were ordering new, the G700 wins. Buy the G700 if you genuinely need five cabin zones, want the latest technology, and the budget is there. Buy the G650ER for everything else. Most buyers should buy the G650ER. Market research reviewed October 8, 2026: Gulfstream G650ER: $45.95M–$47.9M asking — 2016 examples; Gulfstream G700: $73.38M–$82M Vref (July 2026).
