Bell 525 Relentless vs Bombardier Global 7500 vs Embraer Legacy 650 E vs Gulfstream G700

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter, so it fits a different category than the other three long‑range business jets. It is intended for vertical-lift missions and typically carries about 16 passengers, with range on the order of roughly 600–700 nautical miles depending on configuration and reserves. The Embraer Legacy 650E is a large-cabin business jet in the “heavy” class rather than the ultra‑long‑range tier. It commonly seats around 13 passengers (with higher-density layouts possible) and is suited to intercontinental-but-not-top-end missions, with range around 3,900–4,000 nautical miles. The Bombardier Global 7500 and Gulfstream G700 are ultra‑long‑range flagships. Both offer very large cabins and typically accommodate about 14–19 passengers depending on layout, with maximum capacities higher in dense configurations. In range, they lead this group: the Global 7500 is about 7,700 nautical miles, while the G700 is roughly 7,500 nautical miles, enabling nonstop city pairs well beyond what the Legacy 650E can cover and far beyond the helicopter.
