GULFSTREAM IV SERIES

Gulfstream IV Series for Sale — The Aircraft That Redefined the Large-Cabin Category

The Gulfstream IV arrived in 1985 as the most significant advance in large-cabin business jet design since the original G-II — bringing Rolls-Royce Tay engines, a redesigned wing with supercritical section, and a glass cockpit that transformed the flight deck experience compared to the analog G-III it succeeded. The GIV's combination of 4,220 nm range, 14-passenger cabin, and dramatically reduced noise and fuel consumption compared to its Spey-powered predecessor set new benchmarks that competitors spent years trying to match. Through multiple production variants spanning three decades, the Gulfstream IV family became one of the most successful large-cabin business jets in aviation history.

The GIV Family

• Gulfstream IV (G-IV) — Original production aircraft with Rolls-Royce Tay Mk 611-8 engines and Honeywell SPZ-8000 digital avionics. The aircraft that established the GIV's reputation for performance and refinement.
• Gulfstream IVSP — Special Performance variant with increased gross weight, improved hot-and-high performance, and enhanced range. The most common GIV variant on the pre-owned market and the most operationally capable of the original GIV generation.
• Gulfstream G400 — Updated designation bringing Rockwell Collins avionics improvements and enhanced passenger connectivity to the proven GIV airframe.
• Gulfstream G450 — Major evolution with PlaneView flight deck, increased range to 4,350 nm, and enhanced passenger environment. The G450 represented a complete technological refresh of the GIV platform and became one of the most sought-after large-cabin jets in the pre-owned market.

Value Proposition in the Current Market

Pre-owned GIV and GIVSP aircraft represent some of the most compelling value propositions in large-cabin business aviation. The Tay engines — while older technology — are well-supported by Rolls-Royce's network, and enrollment on Rolls-Royce CorporateCare provides predictable maintenance costs. The cabin volume accommodates 12–14 passengers in genuine comfort on routes that no midsize or super-midsize jet can match nonstop. For operators who need large-cabin intercontinental capability but cannot justify the acquisition cost of current-generation aircraft, a well-maintained GIVSP or G450 offers an exceptional performance-per-dollar result.
