Gulfstream G650 vs G550: Key Facts on Range, Cabin, Cost and 2026 Market Prices

The Gulfstream G650 and G550, both now out of production, remain active in the used large-cabin jet market with a typical price gap of roughly $29 million, according to Hagerty Jet Group's quarterly Gulfstream market update and listings on the GlobalAir.com marketplace.

On range, the G650ER leads at 7,500 nautical miles, followed by the base G650 at 7,000 nm and the G550 at 6,750 nm. The G650 also holds a speed advantage, with a maximum cruise speed of 516 knots against the G550's 488 knots — a 28-knot difference translating to approximately 25 minutes on a 3,500 nm trip and about 45 minutes at maximum range. Both aircraft share a 51,000-foot service ceiling and Rolls-Royce turbofan engines; the G650 and G650ER use Rolls-Royce BR725 engines and share the GVI type rating, while the G550 carries the G-V rating, which is not cross-compatible. The G650 cabin measures 46 feet 10 inches long by 8 feet 6 inches wide, totalling 2,138 cubic feet, versus the G550's 43 feet 11 inches by 7 feet 4 inches, or 1,669 cubic feet — 14 inches narrower and nearly three feet shorter.

On operating cost, the G550 runs approximately $9,483 per flight hour against $10,547 for the G650. At 400 flight hours per year, that equates to annual budgets of roughly $3.65 million and $4.06 million respectively — a difference of about $426,000 per year. Used G550 asking prices in the first quarter of 2026 ranged from $15 million to $35 million, averaging $19.27 million. G650 and G650ER listings on GlobalAir.com ranged from $43 million to $53 million, averaging $48 million overall, with G650ERs averaging $46 million.

As of mid-September 2026, GlobalAir.com carried six G550s, six G650ERs and two G650s. Over the prior 12 months, the marketplace recorded 38 G550 sales against 25 across the G650 family. Average time on market was 57 days for the G550, 89 days for the G650 and 152 days for the G650ER. Buyer inquiries in the past 30 days stood at 132 for the G550 against 95 combined for both G650 variants. Hagerty Jet Group reported the G650 appreciated approximately 10% between the fourth quarter of 2025 and the first quarter of 2026.

Gulfstream ended G550 production in July 2021 after more than 600 aircraft. The final G650/G650ER left the Savannah assembly line in February 2025 after more than 500 deliveries. The G650 was succeeded in the product lineup by the G800, which is currently in production. Parts availability, maintenance support and pilot supply for both fleets are described as healthy, with that situation expected to continue for at least a decade.

This split reflects how a manufacturer's own discontinued models can settle into distinct market tiers once production ends: one priced for entry-level large-cabin buyers, the other for those paying for extra range, cabin volume and speed. The G550's 132 inquiries against 95 combined for the G650 family, alongside its shorter 57-day average time on market versus 89 and 152 days for the G650 and G650ER, points to broader demand at the lower price point even as the G650 posted the stronger recent appreciation.

In the pre-owned large-cabin segment, buyers weigh acquisition price against the roughly $426,000 annual operating-cost gap and against cabin and range differences that affect mission suitability, with healthy parts, maintenance and pilot supply for both types removing fleet-age risk as a deciding factor for at least the next decade. That supply outlook, paired with the G650's role as predecessor to the in-production G800, keeps both types viable rather than pushing buyers toward one exclusively.

What happens to G650 and G650ER pricing and inventory levels over coming quarters, particularly whether the reported 10% appreciation continues into subsequent Hagerty Jet Group updates, will indicate whether the two-tier structure is stabilizing or shifting further apart.
