Bell 525 Relentless vs Dassault Falcon 8x vs Gulfstream G700 vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Dassault Falcon 8X and Gulfstream G700 are long‑range business jets. In category terms, the Bell 525 is a modern super‑medium/large civilian helicopter aimed at offshore and corporate missions; the Robinson R66 is a light single‑engine turbine helicopter focused on shorter, lower‑cost utility and private flying. The Falcon 8X and G700 sit in the ultra‑long‑range large‑cabin jet class, built for intercontinental travel at high cruise speeds and altitudes. For range, the Falcon 8X and G700 are the clear leaders, typically capable of roughly 6,000–7,500+ nautical miles depending on configuration and mission, enabling nonstop city pairs across oceans. The Bell 525 is far shorter‑legged by comparison, generally in the several‑hundred‑nautical‑mile class, optimized for regional legs with reserves. The Robinson R66 has the shortest practical mission profile, generally a few hundred nautical miles. Passenger capacity follows a similar pattern: the G700 typically carries the most (often around 13–19), the Falcon 8X slightly fewer (commonly around 12–16), the Bell 525 around 10–16 depending on layout, and the R66 about 4 passengers plus a pilot.
