The new G650 by Gulfstream tops our comparative list costing an average of $58 Million. This aircraft does not tout its price on name-sake alone, as it’s also the best performing jet in this class. Two Rolls-Royce BR725 A1-12 turbofans create 32,200 pounds of combined thrust giving the G650 its ability to travel up to 7,000 nautical miles with a max cruising speed of 611 knots. Like the XRS, this Gulfstream also has a top flight altitude of 51,000 feet. Gulfstream’s PlaneView II avionics system monitors and controls this personal jet. It has a 6.42 foot interior cabin height while measuring 99.76 feet in overall length and 99.58 feet across the wings.
