Bell 525 Relentless vs Cessna Citation Xls vs Dassault Falcon 8x vs Gulfstream G700

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore, corporate, and VIP missions. Compared with the jets, it sits in a different category with far shorter range (roughly 500–600 nautical miles) and a typically smaller passenger load, commonly around 10–16 depending on layout and fuel reserves. The Cessna Citation XLS+ is a midsize business jet designed for efficient regional and transcontinental trips, offering about 1,800–2,100 nautical miles of range and usually seating 8–9 passengers in a standard corporate cabin (often up to about 12 with high‑density configurations). The Dassault Falcon 8X is an ultra‑long‑range large‑cabin jet, typically configured for about 12–16 passengers, with range around 6,400–6,500 nautical miles, enabling many nonstop intercontinental city pairs. The Gulfstream G700 is a flagship ultra‑long‑range jet with a very large cabin, commonly seating about 13–19 passengers, and range around 7,500 nautical miles, generally outpacing the 8X on maximum reach while competing at the top end of comfort and space.
