Aircraft Comparison: Gulfstream GIV vs G450

The Gulfstream GIV and the Gulfstream G450 are closely related: in fact, they come from the same family of private jet jets. Different versions of the same aircraft, the two private planes both fall into the large business aircraft category and are a great choice for accommodating a large number of passengers needing to travel far distances. Below, we compare and contrast the Gulfstream GIV and G450 so you can better understand what makes these two private aircraft unique.

The Gulfstream GIV

The Gulfstream GIV made its debut in 1985 and continues to be a solid choice of aircraft for both business and leisure. It offers plenty of room for up to 13 passengers to relax, conduct business, or comfortably move about the cabin. Seating can be arranged in a conference-style grouping to facilitate meetings that can’t wait. In addition to ample cabin space, the GIV also features a large galley and a full-sized lavatory with shower.

Gulfstream G450

The Gulfstream G450 is a later iteration in the Gulfstream IV family of twin jets, coming onto the scene in 2004. Like its predecessor, it’s an iconic private jet. It’s a business aircraft built not just for long-range flights but for comfort: it has advanced sound suppression technology and an elegantly designed interior to encourage productivity in the air. The Gulfstream G450’s three separate living areas, two bathrooms, and full-size galley feel like a suite in the sky.

Private travelers with a global focus can’t go wrong with the Gulfstream GIV or its later iteration, the Gulfstream G450. The aircraft are similar, with the newer G450 understandably featuring some enhanced and additional features as well as a slightly larger cabin. Both aircraft have 100% fresh oxygen circulated throughout the cabin every two minutes to help passengers feel relaxed and refreshed, as well as 12 panoramic windows.

Slight differences are seen in that the G450 features newer technology, more advanced tech for the crew, and a larger fuselage, as its design was geared more toward creature comforts, like a bed or space for guests. The GIV was created with a focus on business aviation, with less separation between sections in the cabin and open space to facilitate collaboration.
