Bell 525 Relentless vs Dassault Falcon 8x vs Gulfstream G700

The Bell 525 Relentless sits in a different category from the other two: it is a super‑medium, fly‑by‑wire helicopter aimed at offshore, corporate, and government missions. Its range is measured in the hundreds of nautical miles rather than thousands, and typical passenger capacity is around the mid‑teens depending on layout. The Dassault Falcon 8X and Gulfstream G700 are long‑range, ultra‑long‑haul business jets designed for intercontinental travel. The Falcon 8X is a large‑cabin trijet with an ultra‑long range of roughly 6,400 nautical miles and typically carries about 12–16 passengers in executive configurations (with higher maximum seating possible). The Gulfstream G700 is a newer, very large‑cabin, ultra‑long‑range jet with roughly 7,500 nautical miles of range and commonly seats about 13–19 passengers depending on cabin plan. In short, the 525 prioritizes vertical lift and access over distance, while the 8X and especially the G700 prioritize nonstop global range and larger, more flexible cabins.
