The development of the Gulfstream IV and its variants (Gulfstream G400, GIV-ST, G350, G450) was a big advancement from the earlier II and III models. The new Rolls Royce Tay turbofan engines were a large part of that, bringing significant improvements in efficiency and noise reduction. The plane was also made more aerodynamic and the wing redesigned for better lift properties.

The Gulfstream IV has set numerous world records in flights around the world. It has been used to sample atmospheric conditions around developing cycles, a task its well suited for because of its speed and long range capabilities along with ample interior room for passengers and equipment.

The G-IV is a proven high class performer and while it lacks some of the gadgets found and refinements found in newly designed aircraft it will take you far and fast in style.
