| Gulfstream IV
Gulfstreams For Sale at BusinessJet.com The Gulfstream IV is a significantly improved, larger, longer ranging and advanced development of the earlier Gulfstream II and III models.
Gulfstream models are the Rolls-Royce Tay turbofans, which bring significant fuel burn and noise emission improvements despite their higher thrust output than the II and III’s Speys (the IV continues a Gulfstream and Rolls-Royce association that dates back to the original Dart powered Gulfstream I). Other changes include a stretched fuselage and aerodynamically and structurally improved wing with 30% fewer parts, greater fuel capacity and range, increased span tailplane and an advanced EFIS avionics suite with six colour CRT displays. Design work on the IV began in early 1983, with the first of four for military roles (such as maritime patrol and electronic surveillance, depending on equipment fit) it is also offered as a freighter for priority cargo transport (the US Navy has ordered four and the Marines one as C-20G operations support aircraft capable of accommodating 26 passengers or three freight pallets). Both the Gulfstream IV and IV-SP have set a number of records. A

I agree with Ray K about the Gulfstream G-V and Bombardier Global Express. I did a performance analysis on Bombardier Global Express, and in the relation we compared wing loading and power/weight ratio, and these two airplanes in the graph were almost coincident (and difficult to read). G-V and Global Express are powered by the same kind of engine(maybe not the same version), dimensions and performances are really similar and they have no directly comparable competitors ..or smaller business jet like learjet(part of Bombardier company) or Falcon (by Dassault), but these are smaller and shorter range, or airliners converted into business-jets(like BBJ that is 737, or B-727BJ), these are larger and more expensive but they have usually shorter range than G-V and GlobalExpress
