The Gulfstream G450 not only is the best large-cabin, long-range business jet in its class; it’s also a direct descendent of the storied GIV series aircraft. By 2002 when production for that line ceased, over 500 world-class airplanes had been made. Now this outstanding plane has an upgrade and become even more impressive with new features like reaching a maximum operating speed of Mach 0.88 to carry eight people up 4,350 nautical miles at normal cruise speeds of Mach 0.80!
