As the fourth installation in the Gulfstream family line, the GIV SP offers new advancements that the former aircrafts lacked. One of the most significant improvements is the change of engines from the Rolls-Royce Spey to the Rolls-Royce Tay Mk 611-8, used in later jets including the G300 and 400. While the GIV SP sounds like an all business aircraft step inside the GIV SP’s cabin and you will see all the familiar comforts discerning clients demand from a business jet.
