Bombardier Challenger 650 vs Gulfstream G280 vs Gulfstream G500

The Bombardier Challenger 650 and Gulfstream G280 are both super‑midsize business jets, while the Gulfstream G500 steps up into the large‑cabin, long‑range category. In range terms, the Challenger 650 is typically around 4,000 nautical miles, the G280 about 3,600 nautical miles, and the G500 roughly 5,300 nautical miles, making the G500 the clear choice for longer nonstop city pairs. Passenger capacity overlaps but trends upward with size: the Challenger 650 is commonly configured for about 9 to 12 passengers, the G280 typically seats about 8 to 10, and the G500 is often arranged for about 10 to 14. In practical terms, the Challenger 650 emphasizes cabin volume and comfort within the super‑midsize class, the G280 offers strong speed and efficiency for its segment, and the G500 provides a larger cabin and substantially more range for intercontinental‑leaning missions.
